Types

type Abort 

type Abort struct {
	// REQUIRED. HTTP status code to use to abort the Http request.
	HTTPStatus int `json:"httpStatus"`

	// Percentage of requests on which the delay will be injected.
	Percentage *Percentage `json:"percentage,omitempty"`
}

Abort specification is used to prematurely abort a request with a pre-specified error code. The following example will return an HTTP 400 error code for 1 out of every 1000 requests to the "ratings" service "v1".

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:
- route:
  - destination:
      host: ratings.prod.svc.cluster.local
      subset: v1
  fault:
    abort:
      percentage:
        value: 0.1
      httpStatus: 400

```

The _httpStatus_ field is used to indicate the HTTP status code to return to the caller. The optional _percentage_ field can be used to only abort a certain percentage of requests. If not specified, all requests are aborted.

	// inside a HTTP connection manager. This does not apply to the
	// virtual host. Currently, only MERGE operation is allowed on the
	// route configuration objects.
	ApplyToRouteConfiguration ApplyTo = "ROUTE_CONFIGURATION"
	// Applies the patch to a virtual host inside a route configuration.
	ApplyToVirtualHost ApplyTo = "VIRTUAL_HOST"
	// Applies the patch to a route object inside the matched virtual
	// host in a route configuration. Currently, only MERGE operation
	// is allowed on the route objects.
	ApplyToHTTPRoute ApplyTo = "HTTP_ROUTE"
	// Applies the patch to a cluster in a CDS output. Also used to add new clusters.
	ApplyToCluster ApplyTo = "CLUSTER"
)

type CaptureMode 

type CaptureMode string

CaptureMode describes how traffic to a listener is expected to be captured. Applicable only when the listener is bound to an IP. 

const (
	// The default capture mode defined by the environment.
	CaptureModeDefault CaptureMode = "DEFAULT"
	// Capture traffic using IPtables redirection.
	CaptureModeIPTables CaptureMode = "IPTABLES"
	// No traffic capture. When used in an egress listener, the application is
	// expected to explicitly communicate with the listener port or Unix
	// domain socket. When used in an ingress listener, care needs to be taken
	// to ensure that the listener port is not in use by other processes on
	// the host.
	CaptureModeNone CaptureMode = "NONE"
)

type ClusterMatch 

type ClusterMatch struct {
	// The service port for which this cluster was generated.  If
	// omitted, applies to clusters for any port.
	PortNumber uint32 `json:"portNumber,omitempty"`
	// The fully qualified service name for this cluster. If omitted,
	// applies to clusters for any service. For services defined
	// through service entries, the service name is same as the hosts
	// defined in the service entry.
	Service string `json:"service,omitempty"`
	// The subset associated with the service. If omitted, applies to
	// clusters for any subset of a service.
	Subset string `json:"subset,omitempty"`
	// The exact name of the cluster to match. To match a specific
	// cluster by name, such as the internally generated "Passthrough"
	// cluster, leave all fields in clusterMatch empty, except the
	// name.
	Name string `json:"name,omitempty"`
}

Conditions specified in ClusterMatch must be met for the patch to be applied to a cluster.

func (*ClusterMatch) DeepCopy

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type ConnectionPoolSettings 

type ConnectionPoolSettings struct {
	// Settings common to both HTTP and TCP upstream connections.
	TCP *TCPSettings `json:"tcp,omitempty"`

	// HTTP connection pool settings.
	HTTP *HTTPSettings `json:"http,omitempty"`
}

Connection pool settings for an upstream host. The settings apply to each individual host in the upstream service. See Envoy's [circuit breaker](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/upstream/circuit_breaking) for more details. Connection pool settings can be applied at the TCP level as well as at HTTP level.

For example, the following rule sets a limit of 100 connections to redis service called myredissrv with a connect timeout of 30ms

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: bookinfo-redis

spec: 

host: myredissrv.prod.svc.cluster.local
trafficPolicy:
  connectionPool:
    tcp:
      maxConnections: 100
      connectTimeout: 30ms
      tcpKeepalive:
        time: 7200s
        interval: 75s

```

func (*ConnectionPoolSettings) DeepCopy 

func (in *ConnectionPoolSettings) DeepCopy() *ConnectionPoolSettings

type ConsistentHashLB 

type ConsistentHashLB struct {
	// It is required to specify exactly one of these fields as hash key
	// HTTPHeaderName, HTTPCookie, or UseSourceIP.
	// Hash based on a specific HTTP header.
	HTTPHeaderName *string `json:"httpHeaderName,omitempty"`

	// Hash based on HTTP cookie.
	HTTPCookie *HTTPCookie `json:"httpCookie,omitempty"`

	// Hash based on the source IP address.
	UseSourceIP *bool `json:"useSourceIp,omitempty"`

	// The minimum number of virtual nodes to use for the hash
	// ring. Defaults to 1024. Larger ring sizes result in more granular
	// load distributions. If the number of hosts in the load balancing
	// pool is larger than the ring size, each host will be assigned a
	// single virtual node.
	MinimumRingSize *uint64 `json:"minimumRingSize,omitempty"`
}

Consistent Hash-based load balancing can be used to provide soft session affinity based on HTTP headers, cookies or other properties. This load balancing policy is applicable only for HTTP connections. The affinity to a particular destination host will be lost when one or more hosts are added/removed from the destination service.

func (*ConsistentHashLB) DeepCopy 

func (in *ConsistentHashLB) DeepCopy() *ConsistentHashLB

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new ConsistentHashLB.

type CorsPolicy 

type CorsPolicy struct {
	// The list of origins that are allowed to perform CORS requests. The
	// content will be serialized into the Access-Control-Allow-Origin
	// header. Wildcard * will allow all origins.
	AllowOrigin []string `json:"allowOrigin,omitempty"`

	// List of HTTP methods allowed to access the resource. The content will
	// be serialized into the Access-Control-Allow-Methods header.

	// A white list of HTTP headers that the browsers are allowed to
	// access. Serialized into Access-Control-Expose-Headers header.
	ExposeHeaders []string `json:"exposeHeaders,omitempty"`

	// Specifies how long the results of a preflight request can be
	// cached. Translates to the `Access-Control-Max-Age` header.
	MaxAge *string `json:"maxAge,omitempty"`

	// Indicates whether the caller is allowed to send the actual request
	// (not the preflight) using credentials. Translates to
	// `Access-Control-Allow-Credentials` header.
	AllowCredentials *bool `json:"allowCredentials,omitempty"`
}

Describes the Cross-Origin Resource Sharing (CORS) policy, for a given service. Refer to [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS) for further details about cross origin resource sharing. For example, the following rule restricts cross origin requests to those originating from example.com domain using HTTP POST/GET, and sets the `Access-Control-Allow-Credentials` header to false. In addition, it only exposes `X-Foo-bar` header and sets an expiry period of 1 day.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:
- route:
  - destination:
      host: ratings.prod.svc.cluster.local
      subset: v1
  corsPolicy:
    allowOrigin:
    - example.com
    allowMethods:
    - POST
    - GET
    allowCredentials: false
    allowHeaders:
    - X-Foo-Bar
    maxAge: "24h"

```

func (*CorsPolicy) DeepCopy 

func (in *CorsPolicy) DeepCopy() *CorsPolicy

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new CorsPolicy.

func (*CorsPolicy) DeepCopyInto 

func (in *CorsPolicy) DeepCopyInto(out *CorsPolicy)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type Delay 

type Delay struct {
	// REQUIRED. Add a fixed delay before forwarding the request. Format:
	// 1h/1m/1s/1ms. MUST be >=1ms.
	FixedDelay string `json:"fixedDelay"`

	// Percentage of requests on which the delay will be injected.
	Percentage *Percentage `json:"percentage,omitempty"`
}

Delay specification is used to inject latency into the request forwarding path. The following example will introduce a 5 second delay in 1 out of every 1000 requests to the "v1" version of the "reviews" service from all pods with label env: prod

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: reviews-route

spec: 

hosts:
- reviews.prod.svc.cluster.local
http:
- match:
  - sourceLabels:
      env: prod
  route:
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v1
  fault:
    delay:
      percentage:
        value: 0.1
      fixedDelay: 5s

```

The _fixedDelay_ field is used to indicate the amount of delay in seconds. The optional _percentage_ field can be used to only delay a certain percentage of requests. If left unspecified, all request will be delayed.

func (*Delay) DeepCopy 

func (in *Delay) DeepCopy() *Delay

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Delay.

func (*Delay) DeepCopyInto 

func (in *Delay) DeepCopyInto(out *Delay)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type Destination 

type Destination struct {
	// REQUIRED. The name of a service from the service registry. Service
	// names are looked up from the platform's service registry (e.g.,
	// Kubernetes services, Consul services, etc.) and from the hosts
	// declared by [ServiceEntry](https://istio.io/docs/reference/config/networking/v1alpha3/service-entry/#ServiceEntry). Traffic forwarded to
	// destinations that are not found in either of the two, will be dropped.
	//
	// *Note for Kubernetes users*: When short names are used (e.g. "reviews"
	// instead of "reviews.default.svc.cluster.local"), Istio will interpret
	// the short name based on the namespace of the rule, not the service. A
	// rule in the "default" namespace containing a host "reviews will be
	// interpreted as "reviews.default.svc.cluster.local", irrespective of
	// the actual namespace associated with the reviews service. _To avoid
	// potential misconfigurations, it is recommended to always use fully
	// qualified domain names over short names._
	Host string `json:"host"`

	// The name of a subset within the service. Applicable only to services
	// within the mesh. The subset must be defined in a corresponding
	// DestinationRule.
	Subset *string `json:"subset,omitempty"`

	// Specifies the port on the host that is being addressed. If a service
	// exposes only a single port it is not required to explicitly select the
	// port.
	Port *PortSelector `json:"port,omitempty"`
}

Destination indicates the network addressable service to which the request/connection will be sent after processing a routing rule. The destination.host should unambiguously refer to a service in the service registry. Istio's service registry is composed of all the services found in the platform's service registry (e.g., Kubernetes services, Consul services), as well as services declared through the ServiceEntry(https://istio.io/docs/reference/config/networking/v1alpha3/service-entry/#ServiceEntry) resource.

*Note for Kubernetes users*: When short names are used (e.g. "reviews" instead of "reviews.default.svc.cluster.local"), Istio will interpret the short name based on the namespace of the rule, not the service. A rule in the "default" namespace containing a host "reviews will be interpreted as "reviews.default.svc.cluster.local", irrespective of the actual namespace associated with the reviews service. _To avoid potential misconfigurations, it is recommended to always use fully qualified domain names over short names._

The following Kubernetes example routes all traffic by default to pods of the reviews service with label "version: v1" (i.e., subset v1), and some to subset v2, in a Kubernetes environment.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: reviews-route
namespace: foo

spec: 

hosts:
- reviews # interpreted as reviews.foo.svc.cluster.local
http:
- match:
  - uri:
      prefix: "/wpcatalog"
  - uri:
      prefix: "/consumercatalog"
  rewrite:
    uri: "/newcatalog"
  route:
  - destination:
      host: reviews # interpreted as reviews.foo.svc.cluster.local
      subset: v2
- route:
  - destination:
      host: reviews # interpreted as reviews.foo.svc.cluster.local
      subset: v1

```

And the associated DestinationRule

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: reviews-destination
namespace: foo

spec: 

host: reviews # interpreted as reviews.foo.svc.cluster.local
subsets:
- name: v1
  labels:
    version: v1
- name: v2
  labels:
    version: v2

```

The following VirtualService sets a timeout of 5s for all calls to productpage.prod.svc.cluster.local service in Kubernetes. Notice that there are no subsets defined in this rule. Istio will fetch all instances of productpage.prod.svc.cluster.local service from the service registry and populate the sidecar's load balancing pool. Also, notice that this rule is set in the istio-system namespace but uses the fully qualified domain name of the productpage service, productpage.prod.svc.cluster.local. Therefore the rule's namespace does not have an impact in resolving the name of the productpage service.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: my-productpage-rule
namespace: istio-system

spec: 

hosts:
- productpage.prod.svc.cluster.local # ignores rule namespace
http:
- timeout: 5s
  route:
  - destination:
      host: productpage.prod.svc.cluster.local

```

To control routing for traffic bound to services outside the mesh, external services must first be added to Istio's internal service registry using the ServiceEntry resource. VirtualServices can then be defined to control traffic bound to these external services. For example, the following rules define a Service for wikipedia.org and set a timeout of 5s for http requests.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-wikipedia

spec: 

hosts:
- wikipedia.org
location: MESH_EXTERNAL
ports:
- number: 80
  name: example-http
  protocol: HTTP
resolution: DNS

apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: my-wiki-rule

spec: 

hosts:
- wikipedia.org
http:
- timeout: 5s
  route:
  - destination:
      host: wikipedia.org

```

	// REQUIRED. The name of a service from the service registry. Service
	// names are looked up from the platform's service registry (e.g.,
	// Kubernetes services, Consul services, etc.) and from the hosts
	// declared by [ServiceEntries](https://istio.io/docs/reference/config/networking/v1alpha3/service-entry/#ServiceEntry). Rules defined for
	// services that do not exist in the service registry will be ignored.
	//
	// *Note for Kubernetes users*: When short names are used (e.g. "reviews"
	// instead of "reviews.default.svc.cluster.local"), Istio will interpret
	// the short name based on the namespace of the rule, not the service. A

	TrafficPolicy *TrafficPolicy `json:"trafficPolicy,omitempty"`

	// One or more named sets that represent individual versions of a
	// service. Traffic policies can be overridden at subset level.
	Subsets []Subset `json:"subsets,omitempty"`

	// A list of namespaces to which this destination rule is exported.
	// The resolution of a destination rule to apply to a service occurs in the
	// context of a hierarchy of namespaces. Exporting a destination rule allows
	// it to be included in the resolution hierarchy for services in
	// other namespaces. This feature provides a mechanism for service owners
	// and mesh administrators to control the visibility of destination rules
	// across namespace boundaries.
	//
	// If no namespaces are specified then the destination rule is exported to all
	// namespaces by default.
	//
	// The value "." is reserved and defines an export to the same namespace that
	// the destination rule is declared in. Similarly, the value "*" is reserved and
	// defines an export to all namespaces.
	//
	// NOTE: in the current release, the `exportTo` value is restricted to
	// "." or "*" (i.e., the current namespace or all namespaces).
	ExportTo []string `json:"exportTo,omitempty"`
}

`DestinationRule` defines policies that apply to traffic intended for a service after routing has occurred. These rules specify configuration for load balancing, connection pool size from the sidecar, and outlier detection settings to detect and evict unhealthy hosts from the load balancing pool. For example, a simple load balancing policy for the ratings service would look as follows:

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: bookinfo-ratings

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy:
  loadBalancer:
    simple: LEAST_CONN

```

Version specific policies can be specified by defining a named `subset` and overriding the settings specified at the service level. The following rule uses a round robin load balancing policy for all traffic going to a subset named testversion that is composed of endpoints (e.g., pods) with labels (version:v3).

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: bookinfo-ratings

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy:
  loadBalancer:
    simple: LEAST_CONN
subsets:
- name: testversion
  labels:
    version: v3
  trafficPolicy:
    loadBalancer:
      simple: ROUND_ROBIN

```

**Note:** Policies specified for subsets will not take effect until a route rule explicitly sends traffic to this subset.

Traffic policies can be customized to specific ports as well. The following rule uses the least connection load balancing policy for all traffic to port 80, while uses a round robin load balancing setting for traffic to the port 9080.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: bookinfo-ratings-port

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy: # Apply to all ports
  portLevelSettings:
  - port:
      number: 80
    loadBalancer:
      simple: LEAST_CONN
  - port:
      number: 9080
    loadBalancer:
      simple: ROUND_ROBIN

```

`EnvoyFilter` provides a mechanism to customize the Envoy configuration generated by Istio Pilot. Use EnvoyFilter to modify values for certain fields, add specific filters, or even add entirely new listeners, clusters, etc. This feature must be used with care, as incorrect configurations could potentially destabilize the entire mesh. Unlike other Istio networking objects, EnvoyFilters are additively applied. Any number of EnvoyFilters can exist for a given workload in a specific namespace. The order of application of these EnvoyFilters is as follows: all EnvoyFilters in the config [root namespace](https://istio.io/docs/reference/config/istio.mesh.v1alpha1/#MeshConfig), followed by all matching EnvoyFilters in the workload's namespace.

**NOTE 1**: Some aspects of this API is deeply tied to the internal implementation in Istio networking subsystem as well as Envoy's XDS API. While the EnvoyFilter API by itself will maintain backward compatibility, any envoy configuration provided through this mechanism should be carefully monitored across Istio proxy version upgrades, to ensure that deprecated fields are removed and replaced appropriately.

**NOTE 2**: When multiple EnvoyFilters are bound to the same workload in a given namespace, all patches will be processed sequentially in order of creation time. The behavior is undefined if multiple EnvoyFilter configurations conflict with each other.

**NOTE 3**: *_To apply an EnvoyFilter resource to all workloads (sidecars and gateways) in the system, define the resource in the config [root namespace](https://istio.io/docs/reference/config/istio.mesh.v1alpha1/#MeshConfig), without a workloadSelector.

The example below declares a global default EnvoyFilter resource in the root namespace called `istio-config`, that adds a custom protocol filter on all sidecars in the system, for outbound port 9307. The filter should be added before the terminating tcp_proxy filter to take effect. In addition, it sets a 30s idle timeout for all HTTP connections in both gateays and sidecars.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: EnvoyFilter metadata: 

name: custom-protocol
namespace: istio-config # as defined in meshConfig resource.

spec: 

configPatches:

The following example enables Envoy's Lua filter for all inbound HTTP calls arriving at service port 8080 of the reviews service pod with labels "app: reviews", in the bookinfo namespace. The lua filter calls out to an external service internal.org.net:8888 that requires a special cluster definition in envoy. The cluster is also added to the sidecar as part of this configuration.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: EnvoyFilter metadata:

            },
           "authorize call",
           5000)
         end
# The second patch adds the cluster that is referenced by the lua code
# cds match is omitted as a new cluster is being added

type Gateway 

type Gateway struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata,omitempty"`

	Spec GatewaySpec `json:"spec"`
}

`Gateway` describes a load balancer operating at the edge of the mesh receiving incoming or outgoing HTTP/TCP connections. The specification describes a set of ports that should be exposed, the type of protocol to use, SNI configuration for the load balancer, etc.

For example, the following Gateway configuration sets up a proxy to act as a load balancer exposing port 80 and 9080 (http), 443 (https), 9443(https) and port 2379 (TCP) for ingress. The gateway will be applied to the proxy running on a pod with labels `app: my-gateway-controller`. While Istio will configure the proxy to listen on these ports, it is the responsibility of the user to ensure that external traffic to these ports are allowed into the mesh.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-gateway
namespace: some-config-namespace

spec: 

selector:
  app: my-gateway-controller
servers:
- port:
    number: 80
    name: http
    protocol: HTTP
  hosts:
  - uk.bookinfo.com
  - eu.bookinfo.com
  tls:
    httpsRedirect: true # sends 301 redirect for http requests
- port:
    number: 443
    name: https-443
    protocol: HTTPS
  hosts:
  - uk.bookinfo.com
  - eu.bookinfo.com
  tls:
    mode: SIMPLE # enables HTTPS on this port
    serverCertificate: /etc/certs/servercert.pem
    privateKey: /etc/certs/privatekey.pem
- port:
    number: 9443
    name: https-9443
    protocol: HTTPS
  hosts:
  - "bookinfo-namespace/*.bookinfo.com"
  tls:
    mode: SIMPLE # enables HTTPS on this port
    credentialName: bookinfo-secret # fetches certs from Kubernetes secret
- port:
    number: 9080
    name: http-wildcard
    protocol: HTTP
  hosts:
  - "*"
- port:
    number: 2379 # to expose internal service via external port 2379
    name: mongo
    protocol: MONGO
  hosts:
  - "*"

```

The Gateway specification above describes the L4-L6 properties of a load balancer. A `VirtualService` can then be bound to a gateway to control the forwarding of traffic arriving at a particular host or gateway port.

For example, the following VirtualService splits traffic for `https://uk.bookinfo.com/reviews`, `https://eu.bookinfo.com/reviews`, `http://uk.bookinfo.com:9080/reviews`, `http://eu.bookinfo.com:9080/reviews` into two versions (prod and qa) of an internal reviews service on port 9080. In addition, requests containing the cookie "user: dev-123" will be sent to special port 7777 in the qa version. The same rule is also applicable inside the mesh for requests to the "reviews.prod.svc.cluster.local" service. This rule is applicable across ports 443, 9080. Note that `http://uk.bookinfo.com` gets redirected to `https://uk.bookinfo.com` (i.e. 80 redirects to 443).

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: bookinfo-rule
namespace: bookinfo-namespace

spec: 

hosts:
- reviews.prod.svc.cluster.local
- uk.bookinfo.com
- eu.bookinfo.com
gateways:
- some-config-namespace/my-gateway
- mesh # applies to all the sidecars in the mesh
http:
- match:
  - headers:
      cookie:
        exact: "user=dev-123"
  route:
  - destination:
      port:
        number: 7777
      host: reviews.qa.svc.cluster.local
- match:
  - uri:
      prefix: /reviews/
  route:
  - destination:
      port:
        number: 9080 # can be omitted if it's the only port for reviews
      host: reviews.prod.svc.cluster.local
    weight: 80
  - destination:
      host: reviews.qa.svc.cluster.local
    weight: 20

```

The following VirtualService forwards traffic arriving at (external) port 27017 to internal Mongo server on port 5555. This rule is not applicable internally in the mesh as the gateway list omits the reserved name `mesh`.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: bookinfo-Mongo
namespace: bookinfo-namespace

spec: 

hosts:
- mongosvr.prod.svc.cluster.local # name of internal Mongo service
gateways:
- some-config-namespace/my-gateway # can omit the namespace if gateway is in same
                                     namespace as virtual service.
tcp:
- match:
  - port: 27017
  route:
  - destination:
      host: mongo.prod.svc.cluster.local
      port:
        number: 5555

```

It is possible to restrict the set of virtual services that can bind to a gateway server using the namespace/hostname syntax in the hosts field. For example, the following Gateway allows any virtual service in the ns1 namespace to bind to it, while restricting only the virtual service with foo.bar.com host in the ns2 namespace to bind to it.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-gateway
namespace: some-config-namespace

spec: 

selector:
  app: my-gateway-controller
servers:
- port:
    number: 80
    name: http
    protocol: HTTP
  hosts:
  - "ns1/*"
  - "ns2/foo.bar.com"

```

	//   configuration will only match values like "123" but not "a123" or "123a".
	//
	// **Note:** `prefix` matching is currently not supported.
	QueryParams map[string]*v1alpha1.StringMatch `json:"queryParams,omitempty"`

	// Flag to specify whether the URI matching should be case-insensitive.
	//
	// **Note:** The case will be ignored only in the case of `exact` and `prefix`
	// URI matches.
	IgnoreURICase *bool `json:"ignoreUriCase,omitempty"`
}

HttpMatchRequest specifies a set of criterion to be met in order for the rule to be applied to the HTTP request. For example, the following restricts the rule to match only requests where the URL path starts with /ratings/v2/ and the request contains a custom `end-user` header with value `jason`.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:
- match:
  - headers:
      end-user:
        exact: jason
    uri:
      prefix: "/ratings/v2/"
    ignoreUriCase: true
  route:
  - destination:
      host: ratings.prod.svc.cluster.local

```

HTTPMatchRequest CANNOT be empty.

type HTTPRedirect 

type HTTPRedirect struct {
	// On a redirect, overwrite the Path portion of the URL with this
	// value. Note that the entire path will be replaced, irrespective of the
	// request URI being matched as an exact path or prefix.

	// On a redirect, Specifies the HTTP status code to use in the redirect
	// response. The default response code is MOVED_PERMANENTLY (301).
	RedirectCode *uint32 `json:"redirectCode,omitempty"`
}

HTTPRedirect can be used to send a 301 redirect response to the caller, where the Authority/Host and the URI in the response can be swapped with the specified values. For example, the following rule redirects requests for /v1/getProductRatings API on the ratings service to /v1/bookRatings provided by the bookratings service.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:
- match:
  - uri:

type HTTPRetry 

type HTTPRetry struct {
	// REQUIRED. Number of retries for a given request. The interval
	// between retries will be determined automatically (25ms+). Actual
	// number of retries attempted depends on the httpReqTimeout.
	Attempts int `json:"attempts"`

	// Timeout per retry attempt for a given request. format: 1h/1m/1s/1ms. MUST BE >=1ms.
	PerTryTimeout string `json:"perTryTimeout"`

	RetryOn *string `json:"retryOn,omitempty"`
}

Describes the retry policy to use when a HTTP request fails. For example, the following rule sets the maximum number of retries to 3 when calling ratings:v1 service, with a 2s timeout per retry attempt.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: ratings-route

spec: 

hosts:

	// provided in this field will replace the corresponding matched prefix.
	URI *string `json:"uri,omitempty"`

	// rewrite the Authority/Host header with this value.
	Authority *string `json:"authority,omitempty"`
}

HTTPRewrite can be used to rewrite specific parts of a HTTP request before forwarding the request to the destination. Rewrite primitive can be used only with HTTPRouteDestination. The following example demonstrates how to rewrite the URL prefix for api call (/ratings) to ratings service before making the actual API call.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata:

	Mirror *Destination `json:"mirror,omitempty"`

	// Percentage of the traffic to be mirrored by the `mirror` field.
	// Use of integer `mirror_percent` value is deprecated. Use the

	// be 100.
	Weight *int `json:"weight,omitempty"`

	// Header manipulation rules
	Headers *Headers `json:"headers,omitempty"`
}

Each routing rule is associated with one or more service versions (see glossary in beginning of document). Weights associated with the version determine the proportion of traffic it receives. For example, the following rule will route 25% of traffic for the "reviews" service to instances with the "v2" tag and the remaining traffic (i.e., 75%) to "v1".

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: reviews-route

spec: 

hosts:
- reviews.prod.svc.cluster.local
http:
- route:
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v2
    weight: 25
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v1
    weight: 75

```

And the associated DestinationRule

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: reviews-destination

spec: 

host: reviews.prod.svc.cluster.local
subsets:
- name: v1
  labels:
    version: v1
- name: v2
  labels:
    version: v2

```

Traffic can also be split across two entirely different services without having to define new subsets. For example, the following rule forwards 25% of traffic to reviews.com to dev.reviews.com

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: reviews-route-two-domains

spec: 

hosts:

	Response *HeaderOperations `json:"response,omitempty"`
}

Message headers can be manipulated when Envoy forwards requests to, or responses from, a destination service. Header manipulation rules can be specified for a specific route destination or for all destinations. The following VirtualService adds a `test` header with the value `true` to requests that are routed to any `reviews` service destination. It also romoves the `foo` response header, but only from responses coming from the `v1` subset (version) of the `reviews` service.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata:

type OutboundTrafficPolicy 

type OutboundTrafficPolicy struct {
	Mode *OutboundTrafficPolicyMode `json:"mode,omitempty"`
}

`OutboundTrafficPolicy` sets the default behavior of the sidecar for handling outbound traffic from the application. If your application uses one or more external services that are not known apriori, setting the policy to `ALLOW_ANY` will cause the sidecars to route any unknown traffic originating from the application to its requested destination. Users are strongly encouraged to use `ServiceEntry` configurations to explicitly declare any external dependencies, instead of using `ALLOW_ANY`, so that traffic to these services can be monitored.

	MinHealthPercent *int32 `json:"minHealthPercent,omitempty"`
}

A Circuit breaker implementation that tracks the status of each individual host in the upstream service. Applicable to both HTTP and TCP services. For HTTP services, hosts that continually return 5xx errors for API calls are ejected from the pool for a pre-defined period of time. For TCP services, connection timeouts or connection failures to a given host counts as an error when measuring the consecutive errors metric. See Envoy's [outlier detection](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/upstream/outlier) for more details.

The following rule sets a connection pool size of 100 connections and 1000 concurrent HTTP2 requests, with no more than 10 req/connection to "reviews" service. In addition, it configures upstream hosts to be scanned every 5 mins, such that any host that fails 7 consecutive times with 5XX error code will be ejected for 15 minutes.

	Port *Port `json:"port"`

	// REQUIRED. One or more hosts exposed by this gateway.
	// While typically applicable to
	// HTTP services, it can also be used for TCP services using TLS with SNI.
	// A host is specified as a `dnsName` with an optional `namespace/` prefix.
	// The `dnsName` should be specified using FQDN format, optionally including
	// a wildcard character in the left-most component (e.g., `prod/*.example.com`).
	// Set the `dnsName` to `*` to select all `VirtualService` hosts from the
	// specified namespace (e.g.,`prod/*`).
	//
	// The `namespace` can be set to `*` or `.`, representing any or the current
	// namespace, respectively. For example, `*/foo.example.com` selects the

	// Any associated `DestinationRule` in the selected namespace will also be used.
	//
	// A `VirtualService` must be bound to the gateway and must have one or

	// NOTE: Only virtual services exported to the gateway's namespace
	// (e.g., `exportTo` value of `*`) can be referenced.
	// Private configurations (e.g., `exportTo` set to `.`) will not be
	// available. Refer to the `exportTo` setting in `VirtualService`,

	// `unix:///path/to/socket` or `unix://@foobar` (Linux abstract namespace).
	DefaultEndpoint *string `json:"defaultEndpoint,omitempty"`
}

`Server` describes the properties of the proxy on a given load balancer port. For example,

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-ingress

spec: 

selector:
  app: my-ingress-gateway
servers:
- port:
    number: 80
    name: http2
    protocol: HTTP2
  hosts:
  - "*"

```

Another example

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-tcp-ingress

spec: 

selector:
  app: my-tcp-ingress-gateway
servers:
- port:
    number: 27018
    name: mongo
    protocol: MONGO
  hosts:
  - "*"

```

The following is an example of TLS configuration for port 443

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-tls-ingress

spec: 

selector:
  app: my-tls-ingress-gateway
servers:
- port:
    number: 443
    name: https
    protocol: HTTPS
  hosts:
  - "*"
  tls:
    mode: SIMPLE
    serverCertificate: /etc/certs/server.pem

type ServiceEntry 

type ServiceEntry struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata,omitempty"`
	Spec              ServiceEntrySpec `json:"spec"`
}

`ServiceEntry` enables adding additional entries into Istio's internal service registry, so that auto-discovered services in the mesh can access/route to these manually specified services. A service entry describes the properties of a service (DNS name, VIPs, ports, protocols, endpoints). These services could be external to the mesh (e.g., web APIs) or mesh-internal services that are not part of the platform's service registry (e.g., a set of VMs talking to services in Kubernetes).

The following example declares a few external APIs accessed by internal applications over HTTPS. The sidecar inspects the SNI value in the ClientHello message to route to the appropriate external service.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-https

spec: 

hosts:
- api.dropboxapi.com
- www.googleapis.com
- api.facebook.com
location: MESH_EXTERNAL
ports:
- number: 443
  name: https
  protocol: TLS
resolution: DNS

```

The following configuration adds a set of MongoDB instances running on unmanaged VMs to Istio's registry, so that these services can be treated as any other service in the mesh. The associated DestinationRule is used to initiate mTLS connections to the database instances.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-mongocluster

spec: 

hosts:
- mymongodb.somedomain # not used
addresses:
- 192.192.192.192/24 # VIPs
ports:
- number: 27018
  name: mongodb
  protocol: MONGO
location: MESH_INTERNAL
resolution: STATIC
endpoints:
- address: 2.2.2.2
- address: 3.3.3.3

```

and the associated DestinationRule

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: mtls-mongocluster

spec: 

host: mymongodb.somedomain
trafficPolicy:
  tls:
    mode: MUTUAL
    clientCertificate: /etc/certs/myclientcert.pem
    privateKey: /etc/certs/client_private_key.pem
    caCertificates: /etc/certs/rootcacerts.pem

```

The following example uses a combination of service entry and TLS routing in a virtual service to steer traffic based on the SNI value to an internal egress firewall.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-redirect

spec: 

hosts:
- wikipedia.org
- "*.wikipedia.org"
location: MESH_EXTERNAL
ports:
- number: 443
  name: https
  protocol: TLS
resolution: NONE

```

And the associated VirtualService to route based on the SNI value.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: tls-routing

spec: 

hosts:
- wikipedia.org
- "*.wikipedia.org"
tls:
- match:
  - sniHosts:
    - wikipedia.org
    - "*.wikipedia.org"
  route:
  - destination:
      host: internal-egress-firewall.ns1.svc.cluster.local

```

The virtual service with TLS match serves to override the default SNI match. In the absence of a virtual service, traffic will be forwarded to the wikipedia domains.

The following example demonstrates the use of a dedicated egress gateway through which all external service traffic is forwarded. The 'exportTo' field allows for control over the visibility of a service declaration to other namespaces in the mesh. By default, a service is exported to all namespaces. The following example restricts the visibility to the current namespace, represented by ".", so that it cannot be used by other namespaces.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-httpbin
namespace : egress

spec: 

hosts:
- httpbin.com
exportTo:
- "."
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: DNS

```

Define a gateway to handle all egress traffic.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: istio-egressgateway
namespace: istio-system

spec: 

selector:
  istio: egressgateway
servers:
- port:
    number: 80
    name: http
    protocol: HTTP
  hosts:
  - "*"

```

And the associated `VirtualService` to route from the sidecar to the gateway service (`istio-egressgateway.istio-system.svc.cluster.local`), as well as route from the gateway to the external service. Note that the virtual service is exported to all namespaces enabling them to route traffic through the gateway to the external service. Forcing traffic to go through a managed middle proxy like this is a common practice.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: gateway-routing
namespace: egress

spec: 

hosts:
- httpbin.com
exportTo:
- "*"
gateways:
- mesh
- istio-egressgateway
http:
- match:
  - port: 80
    gateways:
    - mesh
  route:
  - destination:
      host: istio-egressgateway.istio-system.svc.cluster.local
- match:
  - port: 80
    gateways:
    - istio-egressgateway
  route:
  - destination:
      host: httpbin.com

```

The following example demonstrates the use of wildcards in the hosts for external services. If the connection has to be routed to the IP address requested by the application (i.e. application resolves DNS and attempts to connect to a specific IP), the discovery mode must be set to `NONE`.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-wildcard-example

spec: 

hosts:
- "*.bar.com"
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: NONE

```

The following example demonstrates a service that is available via a Unix Domain Socket on the host of the client. The resolution must be set to STATIC to use Unix address endpoints.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: unix-domain-socket-example

spec: 

hosts:
- "example.unix.local"
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: STATIC
endpoints:
- address: unix:///var/run/example/socket

```

For HTTP-based services, it is possible to create a `VirtualService` backed by multiple DNS addressable endpoints. In such a scenario, the application can use the `HTTP_PROXY` environment variable to transparently reroute API calls for the `VirtualService` to a chosen backend. For example, the following configuration creates a non-existent external service called foo.bar.com backed by three domains: us.foo.bar.com:8080, uk.foo.bar.com:9080, and in.foo.bar.com:7080

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-dns

spec: 

hosts:
- foo.bar.com
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: DNS
endpoints:
- address: us.foo.bar.com
  ports:
    https: 8080
- address: uk.foo.bar.com
  ports:
    https: 9080
- address: in.foo.bar.com
  ports:
    https: 7080

```

With `HTTP_PROXY=http://localhost/`, calls from the application to `http://foo.bar.com` will be load balanced across the three domains specified above. In other words, a call to `http://foo.bar.com/baz` would be translated to `http://uk.foo.bar.com/baz`.

The following example illustrates the usage of a `ServiceEntry` containing a subject alternate name whose format conforms to the [SPIFFE standard](https://github.com/spiffe/spiffe/blob/master/standards/SPIFFE-ID.md):

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: httpbin
namespace : httpbin-ns

spec: 

hosts:
- httpbin.com
location: MESH_INTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: STATIC
endpoints:
- address: 2.2.2.2
- address: 3.3.3.3
subjectAltNames:
- "spiffe://cluster.local/ns/httpbin-ns/sa/httpbin-service-account"

	// us/us-east-1/az-2/r12, a sidecar from us/us-east-1/az-1/r11 locality

Location specifies whether the service is part of Istio mesh or outside the mesh. Location determines the behavior of several features, such as service-to-service mTLS authentication, policy enforcement, etc. When communicating with services outside the mesh, Istio's mTLS authentication is disabled, and policy enforcement is performed on the client-side as opposed to server-side.

)

type ServiceEntryResolution 

type ServiceEntryResolution string

Resolution determines how the proxy will resolve the IP addresses of the network endpoints associated with the service, so that it can route to one of them. The resolution mode specified here has no impact on how the application resolves the IP address associated with the service. The application may still have to use DNS to resolve the service to an IP so that the outbound traffic can be captured by the Proxy. Alternatively, for HTTP services, the application could directly communicate with the proxy (e.g., by setting HTTP_PROXY) to talk to these services. 

const (
	// Assume that incoming connections have already been resolved (to a
	// specific destination IP address). Such connections are typically
	// routed via the proxy using mechanisms such as IP table REDIRECT/

type Sidecar 

type Sidecar struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata,omitempty"`

	Spec SidecarSpec `json:"spec"`
}

Sidecar describes the configuration of the sidecar proxy that mediates inbound and outbound communication to the workload instance it is attached to. By default, Istio will program all sidecar proxies in the mesh with the necessary configuration required to reach every workload instance in the mesh, as well as accept traffic on all the ports associated with the workload. The `SidecarSpec` configuration provides a way to fine tune the set of ports, protocols that the proxy will accept when forwarding traffic to and from the workload. In addition, it is possible to restrict the set of services that the proxy can reach when forwarding outbound traffic from workload instances.

Services and configuration in a mesh are organized into one or more namespaces (e.g., a Kubernetes namespace or a CF org/space). A `SidecarSpec` configuration in a namespace will apply to one or more workload instances in the same namespace, selected using the `workloadSelector` field. In the absence of a `workloadSelector`, it will apply to all workload instances in the same namespace. When determining the `SidecarSpec` configuration to be applied to a workload instance, preference will be given to the resource with a `workloadSelector` that selects this workload instance, over a `SidecarSpec` configuration without any `workloadSelector`.

NOTE 1: *_Each namespace can have only one `SidecarSpec` configuration without any `workloadSelector`_*. The behavior of the system is undefined if more than one selector-less `SidecarSpec` configurations exist in a given namespace. The behavior of the system is undefined if two or more `SidecarSpec` configurations with a `workloadSelector` select the same workload instance.

NOTE 2: *_A `SidecarSpec` configuration in the `MeshConfig` [root namespace](https://istio.io/docs/reference/config/istio.mesh.v1alpha1/#MeshConfig) will be applied by default to all namespaces without a `SidecarSpec` configuration_*. This global default `SidecarSpec` configuration should not have any `workloadSelector`.

The example below declares a global default `SidecarSpec` configuration in the root namespace called `istio-config`, that configures sidecars in all namespaces to allow egress traffic only to other workloads in the same namespace, and to services in the `istio-system` namespace.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: SidecarSpec metadata: 

name: default
namespace: istio-config

spec: 

egress:
- hosts:
  - "./*"
  - "istio-system/*"

```

The example below declares a `SidecarSpec` configuration in the `prod-us1` namespace that overrides the global default defined above, and configures the sidecars in the namespace to allow egress traffic to public services in the `prod-us1`, `prod-apis`, and the `istio-system` namespaces.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: SidecarSpec metadata: 

name: default
namespace: prod-us1

spec: 

egress:
- hosts:
  - "prod-us1/*"
  - "prod-apis/*"
  - "istio-system/*"

```

The example below declares a `SidecarSpec` configuration in the `prod-us1` namespace that accepts inbound HTTP traffic on port 9080 and forwards it to the attached workload instance listening on a Unix domain socket. In the egress direction, in addition to the `istio-system` namespace, the sidecar proxies only HTTP traffic bound for port 9080 for services in the `prod-us1` namespace.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: SidecarSpec metadata: 

name: default
namespace: prod-us1

spec: 

ingress:
- port:
    number: 9080
    protocol: HTTP
    name: somename
  defaultEndpoint: unix:///var/run/someuds.sock
egress:
- port:
    number: 9080
    protocol: HTTP
    name: egresshttp
  hosts:
  - "prod-us1/*"
- hosts:
  - "istio-system/*"

```

If the workload is deployed without IPTables-based traffic capture, the `SidecarSpec` configuration is the only way to configure the ports on the proxy attached to the workload instance. The following example declares a `SidecarSpec` configuration in the `prod-us1` namespace for all pods with labels `app: productpage` belonging to the `productpage.prod-us1` service. Assuming that these pods are deployed without IPtable rules (i.e. the `istio-init` container) and the proxy metadata `ISTIO_META_INTERCEPTION_MODE` is set to `NONE`, the specification, below, allows such pods to receive HTTP traffic on port 9080 and forward it to the application listening on `127.0.0.1:8080`. It also allows the application to communicate with a backing MySQL database on `127.0.0.1:3306`, that then gets proxied to the externally hosted MySQL service at `mysql.foo.com:3306`.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: SidecarSpec metadata: 

name: no-ip-tables
namespace: prod-us1

spec: 

workloadSelector:
  labels:
    app: productpage
ingress:
- port:
    number: 9080 # binds to proxy_instance_ip:9080 (0.0.0.0:9080, if no unicast IP is available for the instance)
    protocol: HTTP
    name: somename
  defaultEndpoint: 127.0.0.1:8080
  captureMode: NONE # not needed if metadata is set for entire proxy
egress:
- port:
    number: 3306
    protocol: MYSQL
    name: egressmysql
  captureMode: NONE # not needed if metadata is set for entire proxy
  bind: 127.0.0.1
  hosts:
  - "*/mysql.foo.com"

```

And the associated service entry for routing to `mysql.foo.com:3306`

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-mysql
namespace: ns1

spec: 

hosts:
- mysql.foo.com
ports:
- number: 3306
  name: mysql
  protocol: MYSQL
location: MESH_EXTERNAL
resolution: DNS

```

It is also possible to mix and match traffic capture modes in a single proxy. For example, consider a setup where internal services are on the `192.168.0.0/16` subnet. So, IP tables are setup on the VM to capture all outbound traffic on `192.168.0.0/16` subnet. Assume that the VM has an additional network interface on `172.16.0.0/16` subnet for inbound traffic. The following `SidecarSpec` configuration allows the VM to expose a listener on `172.16.1.32:80` (the VM's IP) for traffic arriving from the `172.16.0.0/16` subnet. Note that in this scenario, the `ISTIO_META_INTERCEPTION_MODE` metadata on the proxy in the VM should contain `REDIRECT` or `TPROXY` as its value, implying that IP tables based traffic capture is active.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: SidecarSpec metadata: 

name: partial-ip-tables
namespace: prod-us1

spec: 

workloadSelector:
  labels:
    app: productpage
ingress:
- bind: 172.16.1.32
  port:
    number: 80 # binds to 172.16.1.32:80
    protocol: HTTP
    name: somename
  defaultEndpoint: 127.0.0.1:8080
  captureMode: NONE
egress:
  # use the system detected defaults
  # sets up configuration to handle outbound traffic to services
  # in 192.168.0.0/16 subnet, based on information provided by the
  # service registry
- captureMode: IPTABLES
  hosts:
  - "*/*"

	Name string `json:"name,omitempty"`
}

type Subset 

type Subset struct {
	// REQUIRED. Name of the subset. The service name and the subset name can
	// be used for traffic splitting in a route rule.
	Name string `json:"name"`

	// Labels apply a filter over the endpoints of a service in the
	// service registry. See route rules for examples of usage.
	Labels map[string]string `json:"labels"`

	// Traffic policies that apply to this subset. Subsets inherit the
	// traffic policies specified at the DestinationRule level. Settings
	// specified at the subset level will override the corresponding settings
	// specified at the DestinationRule level.
	TrafficPolicy *TrafficPolicy `json:"trafficPolicy,omitempty"`
}

A subset of endpoints of a service. Subsets can be used for scenarios like A/B testing, or routing to a specific version of a service. Refer to VirtualService(https://istio.io/docs/reference/config/networking/v1alpha3/virtual-service/#VirtualService) documentation for examples of using subsets in these scenarios. In addition, traffic policies defined at the service-level can be overridden at a subset-level. The following rule uses a round robin load balancing policy for all traffic going to a subset named testversion that is composed of endpoints (e.g., pods) with labels (version:v3).

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: bookinfo-ratings

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy:
  loadBalancer:
    simple: LEAST_CONN
subsets:
- name: testversion
  labels:
    version: v3
  trafficPolicy:
    loadBalancer:
      simple: ROUND_ROBIN

```

**Note:** Policies specified for subsets will not take effect until a route rule explicitly sends traffic to this subset.

One or more labels are typically required to identify the subset destination, however, when the corresponding DestinationRule represents a host that supports multiple SNI hosts (e.g., an egress gateway), a subset without labels may be meaningful. In this case a traffic policy with TLSSettings(#TLSSettings) can be used to identify a specific SNI host corresponding to the named subset.

Configuration affecting traffic routing. Here are a few terms useful to define in the context of traffic routing.

`Service` a unit of application behavior bound to a unique name in a service registry. Services consist of multiple network *endpoints* implemented by workload instances running on pods, containers, VMs etc.

`Service versions (a.k.a. subsets)` - In a continuous deployment scenario, for a given service, there can be distinct subsets of instances running different variants of the application binary. These variants are not necessarily different API versions. They could be iterative changes to the same service, deployed in different environments (prod, staging, dev, etc.). Common scenarios where this occurs include A/B testing, canary rollouts, etc. The choice of a particular version can be decided based on various criterion (headers, url, etc.) and/or by weights assigned to each version. Each service has a default version consisting of all its instances.

`Source` - A downstream client calling a service.

`Host` - The address used by a client when attempting to connect to a service.

`Access model` - Applications address only the destination service (Host) without knowledge of individual service versions (subsets). The actual choice of the version is determined by the proxy/sidecar, enabling the application code to decouple itself from the evolution of dependent services.

A `VirtualService` defines a set of traffic routing rules to apply when a host is addressed. Each routing rule defines matching criteria for traffic of a specific protocol. If the traffic is matched, then it is sent to a named destination service (or subset/version of it) defined in the registry.

The source of traffic can also be matched in a routing rule. This allows routing to be customized for specific client contexts.

The following example on Kubernetes, routes all HTTP traffic by default to pods of the reviews service with label "version: v1". In addition, HTTP requests with path starting with /wpcatalog/ or /consumercatalog/ will be rewritten to /newcatalog and sent to pods with label "version: v2".

```yaml apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: 

name: reviews-route

spec: 

hosts:
- reviews.prod.svc.cluster.local
http:
- name: "reviews-v2-routes"
  match:
  - uri:
      prefix: "/wpcatalog"
  - uri:
      prefix: "/consumercatalog"
  rewrite:
    uri: "/newcatalog"
  route:
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v2
- name: "reviews-v1-route"
  route:
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v1

```

A subset/version of a route destination is identified with a reference to a named service subset which must be declared in a corresponding `DestinationRule`.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: 

name: reviews-destination

spec: 

host: reviews.prod.svc.cluster.local
subsets:
- name: v1
  labels:
    version: v1
- name: v2
  labels:
    version: v2

	// Network enables Istio to group endpoints resident in the same L3

	Network string `json:"network,omitempty"`
	// The locality associated with the endpoint. A locality corresponds

	// standard service endpoint.
	Locality string `json:"locality,omitempty"`

	// with higher weights will receive proportionally higher traffic.
	Weight uint32 `json:"weight,omitempty"`
	// The service account associated with the workload if a sidecar

}

`WorkloadEntry` enables operators to describe the properties of a single non-Kubernetes workload such as a VM or a bare metal server as it is are onboarded into the mesh. A `WorkloadEntry` must be accompanied by an Istio `ServiceEntry` that selects the workload through the appropriate labels and provides the service definition for a `MESH_INTERNAL` service (hostnames, port properties, etc.). A `ServiceEntry` object can select multiple workload entries as well as Kubernetes pods based on the label selector specified in the service entry.

When a workload connects to `istiod`, the status field in the custom resource will be updated to indicate the health of the workload along with other details, similar to how Kubernetes updates the status of a pod.

The following example declares a workload entry representing a VM for the `details.bookinfo.com` service. This VM has sidecar installed and bootstrapped using the `details-legacy` service account. The sidecar receives HTTP traffic on port 80 (wrapped in istio mutual TLS) and forwards it to the application on the localhost on the same port.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: WorkloadEntry metadata: 

name: details-svc

spec: 

# use of the service account indicates that the workload has a
# sidecar proxy bootstrapped with this service account. Pods with
# sidecars will automatically communicate with the workload using
# istio mutual TLS.
serviceAccount: details-legacy
address: 2.2.2.2
labels:
  app: details-legacy
  instance-id: vm1
# ports if not specified will be the same as service ports

```

and the associated service entry

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: details-svc

spec: 

hosts:
- details.bookinfo.com
location: MESH_INTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: STATIC
workloadSelector:
  labels:
    app: details-legacy

```

The following example declares the same VM workload using its fully qualified DNS name. The service entry's resolution mode should be changed to DNS to indicate that the client-side sidecars should dynamically resolve the DNS name at runtime before forwarding the request.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: WorkloadEntry metadata: 

name: details-svc

spec: 

# use of the service account indicates that the workload has a
# sidecar proxy bootstrapped with this service account. Pods with
# sidecars will automatically communicate with the workload using
# istio mutual TLS.
serviceAccount: details-legacy
address: vm1.vpc01.corp.net
labels:
  app: details-legacy
  instance-id: vm1
# ports if not specified will be the same as service ports

```

and the associated service entry

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: details-svc

spec: 

hosts:
- details.bookinfo.com
location: MESH_INTERNAL
ports:

  name: http
  protocol: HTTP
resolution: DNS
