Types

type Action 

type Action struct {
	// Required. Fully qualified name of the handler to invoke.
	// Must match the `name` of a [Handler][istio.policy.v1beta1.Handler.name].
	Handler string `protobuf:"bytes,2,opt,name=handler,proto3" json:"handler,omitempty"`
	// Required. Each value must match the fully qualified name of the
	// [Instance][istio.policy.v1beta1.Instance.name]s.
	// Referenced instances are evaluated by resolving the attributes/literals for all the fields.
	// The constructed objects are then passed to the `handler` referenced within this action.
	Instances []string `protobuf:"bytes,3,rep,name=instances" json:"instances,omitempty"`
}

Action describes which Handler[istio.policy.v1beta1.Handler] to invoke and what data to pass to it for processing.

The following example instructs Mixer to invoke 'prometheus-handler' handler and pass it the object constructed using the instance 'RequestCountByService'.

```yaml 

handler: prometheus-handler
instances:
- RequestCountByService

```

	//
	// Where `IDENT` must match the regular expression `[a-z][a-z0-9]+` and `SEPARATOR` must
	// match the regular expression `[\.-]`.
	//
	// Attribute names must be unique within a single Istio deployment. The set of canonical

}

AttributeInfo describes the schema of an Istio `Attribute`.

Istio Attributes

Istio uses `attributes` to describe runtime activities of Istio services. An Istio attribute carries a specific piece of information about an activity, such as the error code of an API request, the latency of an API request, or the original IP address of a TCP connection. The attributes are often generated and consumed by different services. For example, a frontend service can generate an authenticated user attribute and pass it to a backend service for access control purpose.

To simplify the system and improve developer experience, Istio uses shared attribute definitions across all components. For example, the same authenticated user attribute will be used for logging, monitoring, analytics, billing, access control, auditing. Many Istio components provide their functionality by collecting, generating, and operating on attributes. For example, the proxy collects the error code attribute, and the logging stores it into a log.

Design

Each Istio attribute must conform to an `AttributeInfo` in an `AttributeManifest` in the current Istio deployment at runtime. An [`AttributeInfo`][istio.policy.v1beta1] is used to define an attribute's metadata: the type of its value and a detailed description that explains the semantics of the attribute type. Each attribute's name is globally unique; in other words an attribute name can only appear once across all manifests.

The runtime presentation of an attribute is intentionally left out of this specification, because passing attribute using JSON, XML, or Protocol Buffers does not change the semantics of the attribute. Different implementations can choose different representations based on their needs.

HTTP Mapping

Because many systems already have REST APIs, it makes sense to define a standard HTTP mapping for Istio attributes that are compatible with typical REST APIs. The design is to map one attribute to one HTTP header, the attribute name and value becomes the HTTP header name and value. The actual encoding scheme will be decided later.

type Handler 

type Handler struct {

	// to refer to this handler.
	Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
	// Required. The name of the compiled in adapter this handler instantiates. For referencing non compiled-in
	// adapters, use the `adapter` field instead.
	//
	// The value must match the name of the available adapter Mixer is built with. An adapter's name is typically a
	// constant in its code.
	CompiledAdapter string `protobuf:"bytes,67794676,opt,name=compiled_adapter,json=compiledAdapter,proto3" json:"compiled_adapter,omitempty"`
	// Required. The name of a specific adapter implementation. For referencing compiled-in
	// adapters, use the `compiled_adapter` field instead.
	//
	// An adapter's implementation name is typically a constant in its code.
	Adapter string `protobuf:"bytes,2,opt,name=adapter,proto3" json:"adapter,omitempty"`
	// Optional. Depends on adapter implementation. Struct representation of a
	// proto defined by the adapter implementation; this varies depending on the value of field `adapter`.
	Params interface{} `protobuf:"bytes,3,opt,name=params" json:"params,omitempty"`
	// Optional. Information on how to connect to the out-of-process adapter.
	// This is used if the adapter is not compiled into Mixer binary and is running as a separate process.
	Connection *Connection `protobuf:"bytes,4,opt,name=connection" json:"connection,omitempty"`
}

Handler allows the operator to configure a specific adapter implementation. Each adapter implementation defines its own `params` proto.

In the following example we define a `metrics` handler for the `prometheus` adapter. The example is in the form of a kubernetes resource: * The `metadata.name` is the name of the handler * The `kind` refers to the adapter name * The `spec` block represents adapter-specific configuration as well as the connection information

```yaml # Sample-1: No connection specified (for compiled in adapters) # Note: if connection information is not specified, the adapter configuration is directly inside # `spec` block. This is going to be DEPRECATED in favor of Sample-2 apiVersion: "config.istio.io/v1alpha2" kind: prometheus metadata: 

name: handler
namespace: istio-system

spec: 

metrics:
- name: request_count
  instance_name: requestcount.metric.istio-system
  kind: COUNTER
  label_names:
  - source_service
  - source_version
  - destination_service
  - destination_version

--- # Sample-2: With connection information (for out-of-process adapters) # Note: Unlike sample-1, the adapter configuration is parallel to `connection` and is nested inside `param` block. apiVersion: "config.istio.io/v1alpha2" kind: prometheus metadata: 

name: handler
namespace: istio-system

spec: 

param:
  metrics:
  - name: request_count
    instance_name: requestcount.metric.istio-system
    kind: COUNTER
    label_names:
    - source_service
    - source_version
    - destination_service
    - destination_version
connection:
  address: localhost:8090

type Instance 

type Instance struct {
	// Required. The name of this instance
	//
	// Must be unique amongst other Instances in scope. Used by [Action][istio.policy.v1beta1.Action] to refer
	// to an instance produced by this instance.
	Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
	// Required. The name of the compiled in template this instance creates instances for. For referencing non compiled-in
	// templates, use the `template` field instead.
	//
	// The value must match the name of the available template Mixer is built with.

	// Required. Depends on referenced template. Struct representation of a
	// proto defined by the template; this varies depending on the value of field `template`.
	Params interface{} `protobuf:"bytes,3,opt,name=params" json:"params,omitempty"`
}

An Instance tells Mixer how to create instances for particular template.

Instance is defined by the operator. Instance is defined relative to a known template. Their purpose is to tell Mixer how to use attributes or literals to produce instances of the specified template at runtime.

The following example instructs Mixer to construct an instance associated with template 'istio.mixer.adapter.metric.Metric'. It provides a mapping from the template's fields to expressions. Instances produced with this instance can be referenced by [Actions][istio.policy.v1beta1.Action] using name 'RequestCountByService'

```yaml

  • name: RequestCountByService template: istio.mixer.adapter.metric.Metric params: value: 1 dimensions: source: source.service destination_ip: destination.ip

	// request it evaluates the match expression and executes all the associated `actions`
	// if the match evaluates to true.
	//
	// A few example match:
	//
	// * an empty match evaluates to `true`
	// * `true`, a boolean literal; a rule with this match will always be executed
	// * `destination.service == ratings*` selects any request targeting a service whose
	// name starts with "ratings"
	// * `attr1 == "20" && attr2 == "30"` logical AND, OR, and NOT are also available
	Match string `protobuf:"bytes,1,opt,name=match,proto3" json:"match,omitempty"`
	// Optional. The actions that will be executed when match evaluates to `true`.
	Actions []*Action `protobuf:"bytes,2,rep,name=actions" json:"actions,omitempty"`
}

A Rule is a selector and a set of intentions to be executed when the selector is `true`

The following example instructs Mixer to invoke 'prometheus-handler' handler for all services and pass it the instance constructed using the 'RequestCountByService' instance.

```yaml

  • match: destination.service == "*" actions:
  • handler: prometheus-handler instances:
  • RequestCountByService

An instance field of type Value denotes that the expression for the field is of dynamic type and can evalaute to any ValueType[istio.policy.v1beta1.ValueType] enum values. For example, when authoring an instance configuration for a template that has a field `data` of type `istio.policy.v1beta1.Value`, both of the following expressions are valid `data: source.ip | ip("0.0.0.0")`, `data: request.id | ""`; the resulting type is either ValueType.IP_ADDRESS or ValueType.STRING for the two cases respectively.

Objects of type Value are also passed to the adapters during request-time. There is a 1:1 mapping between oneof fields in `Value` and enum values inside `ValueType`. Depending on the expression's evaluated `ValueType`, the equivalent oneof field in `Value` is populated by Mixer and passed to the adapters.

type ValueType 

type ValueType int32

ValueType describes the types that values in the Istio system can take. These are used to describe the type of Attributes at run time, describe the type of the result of evaluating an expression, and to describe the runtime type of fields of other descriptors. 

const (
	// Invalid, default value.
	VALUE_TYPE_UNSPECIFIED ValueType = 0
	// An undiscriminated variable-length string.
	STRING ValueType = 1
	// An undiscriminated 64-bit signed integer.
