	SkipValidate bool

	// CSRMaxPerSecond is a rate limit on processing Connect Certificate Signing
	// Requests on the servers. It applies to all CA providers so can be used to
	// limit rate to an external CA too. 0 disables the rate limit. Defaults to 50
	// which is low enough to prevent overload of a reasonably sized production
	// server while allowing a cluster with 1000 service instances to complete a
	// rotation in 20 seconds. For reference a quad-core 2017 MacBook pro can
	// process 100 signing RPCs a second while using less than half of one core.
	// For large clusters with powerful servers it's advisable to increase this
	// rate or to disable this limit and instead rely on CSRMaxConcurrent to only
	// consume a subset of the server's cores.
	CSRMaxPerSecond float32

	// CSRMaxConcurrent is a limit on how many concurrent CSR signing requests
	// will be processed in parallel. New incoming signing requests will try for
	// `consul.csrSemaphoreWait` (currently 500ms) for a slot before being
	// rejected with a "rate limited" backpressure response. This effectively sets
	// how many CPU cores can be occupied by Connect CA signing activity and
	// should be a (small) subset of your server's available cores to allow other
	// tasks to complete when a barrage of CSRs come in (e.g. after a CA root
	// rotation). Setting to 0 disables the limit, attempting to sign certs
	// immediately in the RPC goroutine. This is 0 by default and CSRMaxPerSecond
	// is used. This is ignored if CSRMaxPerSecond is non-zero.
	CSRMaxConcurrent int
}

type ConnectManagedProxy added in v1.2.0 

type ConnectManagedProxy struct {
	// ExecMode is one of daemon or script.
	ExecMode ProxyExecMode

	// Command is the command to execute. Empty defaults to self-invoking the same
	// consul binary with proxy subcomand for ProxyExecModeDaemon and is an error
	// for ProxyExecModeScript.
	Command []string

	// Config is the arbitrary configuration data provided with the registration.
	Config map[string]interface{}

	// Upstreams are the dependencies the proxy should setup outgoing listners for.
	Upstreams Upstreams

	// ProxyService is a pointer to the local proxy's service record for
	// convenience. The proxies ID and name etc. can be read from there. It may be
	// nil if the agent is starting up and hasn't registered the service yet. We
	// ignore it when calculating the hash value since the only thing that effects
	// the proxy's config is the ID of the target service which is already
	// represented below.
	ProxyService *NodeService `hash:"ignore"`

	// TargetServiceID is the ID of the target service on the localhost. It may
	// not exist yet since bootstrapping is allowed to happen in either order.
	TargetServiceID string
}

ConnectManagedProxy represents the agent-local state for a configured proxy instance. This is never stored or sent to the servers and is only used to store the config for the proxy that the agent needs to track. For now it's really generic with only the fields the agent needs to act on defined while the rest of the proxy config is passed as opaque bag of attributes to support arbitrary config params for third-party proxy integrations. "External" proxies by definition register themselves and manage their own config externally so are never represented in agent state.

func (*ConnectManagedProxy) ParseConfig added in v1.2.0 

func (p *ConnectManagedProxy) ParseConfig() (*ConnectManagedProxyConfig, error)

ParseConfig attempts to read the fields we care about from the otherwise opaque config map. They are all optional but it may fail if one is specified but an invalid value.

type ConnectManagedProxyConfig added in v1.2.0 

type ConnectManagedProxyConfig struct {
	BindAddress         string `mapstructure:"bind_address"`

	LocalServiceAddress string `mapstructure:"local_service_address"`
	LocalServicePort    int    `mapstructure:"local_service_port"`
}

ConnectManagedProxyConfig represents the parts of the proxy config the agent needs to understand. It's bad UX to make the user specify these separately just to make parsing simpler for us so this encapsulates the fields in ConnectManagedProxy.Config that we care about. They are all optional anyway and this is used to decode them with mapstructure.

type ConnectProxyConfig added in v1.3.0 

type ConnectProxyConfig struct {
	// DestinationServiceName is required and is the name of the service to accept
	// traffic for.
	DestinationServiceName string `json:",omitempty"`

	// DestinationServiceID is optional and should only be specified for
	// "side-car" style proxies where the proxy is in front of just a single
	// instance of the service. It should be set to the service ID of the instance
	// being represented which must be registered to the same agent. It's valid to
	// provide a service ID that does not yet exist to avoid timing issues when
	// bootstrapping a service with a proxy.
	DestinationServiceID string `json:",omitempty"`

	// LocalServiceAddress is the address of the local service instance. It is
	// optional and should only be specified for "side-car" style proxies. It will
	// default to 127.0.0.1 if the proxy is a "side-car" (DestinationServiceID is
	// set) but otherwise will be ignored.
	LocalServiceAddress string `json:",omitempty"`

	// LocalServicePort is the port of the local service instance. It is optional
	// and should only be specified for "side-car" style proxies. It will default
	// to the registered port for the instance if the proxy is a "side-car"
	// (DestinationServiceID is set) but otherwise will be ignored.
	LocalServicePort int `json:",omitempty"`

	// Config is the arbitrary configuration data provided with the proxy
	// registration.
	Config map[string]interface{} `json:",omitempty"`

	// Upstreams describes any upstream dependencies the proxy instance should
	// setup.
	Upstreams Upstreams `json:",omitempty"`
}

ConnectProxyConfig describes the configuration needed for any proxy managed or unmanaged. It describes a single logical service's listener and optionally upstreams and sidecar-related config for a single instance. To describe a centralised proxy that routed traffic for multiple services, a different one of these would be needed for each, sharing the same LogicalProxyID.

	//
	// Note that we DON'T validate trust domain during AuthZ since it causes

	// only time the additional validation adds value is where the cluster shares
	// an external root (e.g. organization-wide root) with another distinct Consul
	// cluster or PKI system. In this case, x509 Name Constraints can be added to

	// provide additional bounds on the last contact time from the leader. It's
	// expected that servers that are partitioned are noticed and replaced in a
	// timely way by operators while the same may not be true for client agents.
	UseCache bool

	// If set and AllowStale is true, will try first a stale
	// read, and then will perform a consistent read if stale
	// read is older than value.
	MaxStaleDuration time.Duration

	// MaxAge limits how old a cached value will be returned if UseCache is true.
	// If there is a cached response that is older than the MaxAge, it is treated

	// StaleIfError to a longer duration to change this behaviour. It is ignored
	// if the endpoint supports background refresh caching. See
	// https://www.consul.io/api/index.html#agent-caching for more details.
	MaxAge time.Duration

	// MustRevalidate forces the agent to fetch a fresh version of a cached
	// resource or at least validate that the cached version is still fresh. It is
	// implied by either max-age=0 or must-revalidate Cache-Control headers. It
	// only makes sense when UseCache is true. We store it since MaxAge = 0 is the
	// default unset value.
	MustRevalidate bool

	// StaleIfError specifies how stale the client will accept a cached response
	// if the servers are unavailable to fetch a fresh one. Only makes sense when
	// UseCache is true and MaxAge is set to a lower, non-zero value. It is
	// ignored if the endpoint supports background refresh caching. See

func (*RegisterRequest) RequestDatacenter 

func (r *RegisterRequest) RequestDatacenter() string

type ServiceConnect added in v1.2.0 

type ServiceConnect struct {
	// Native is true when this service can natively understand Connect.
	Native bool `json:",omitempty"`

	// Proxy configures a connect proxy instance for the service. This is
	// only used for agent service definitions and is invalid for non-agent
	// (catalog API) definitions.
	Proxy *ServiceDefinitionConnectProxy `json:",omitempty"`

	// SidecarService is a nested Service Definition to register at the same time.
	// It's purely a convenience mechanism to allow specifying a sidecar service
	// along with the application service definition. It's nested nature allows
	// all of the fields to be defaulted which can reduce the amount of
	// boilerplate needed to register a sidecar service separately, but the end
	// result is identical to just making a second service registration via any
	// other means.
	SidecarService *ServiceDefinition `json:",omitempty"`
}

ServiceConnect are the shared Connect settings between all service definitions from the agent to the state store.

type ServiceDefinition 

type ServiceDefinition struct {

	ProxyDestination string `json:",omitempty"`

	// Proxy is the configuration set for Kind = connect-proxy. It is mandatory in
	// that case and an error to be set for any other kind. This config is part of
	// a proxy service definition and is distinct from but shares some fields with
	// the Connect.Proxy which configures a managed proxy as part of the actual
	// service's definition. This duplication is ugly but seemed better than the
	// alternative which was to re-use the same struct fields for both cases even
	// though the semantics are different and the non-shared fields make no sense
	// in the other case. ProxyConfig may be a more natural name here, but it's
	// confusing for the UX because one of the fields in ConnectProxyConfig is
	// also called just "Config"
	Proxy *ConnectProxyConfig

	Connect *ServiceConnect
}

ServiceDefinition is used to JSON decode the Service definitions. For documentation on specific fields see NodeService which is better documented.

func (s *ServiceDefinition) ConnectManagedProxy() (*ConnectManagedProxy, error)

ConnectManagedProxy returns a ConnectManagedProxy from the ServiceDefinition if one is configured validly. Note that is may return nil if no proxy is configured and will also return nil error in this case too as it's an expected case. The error returned indicates that there was an attempt to configure a proxy made but that it was invalid input, e.g. invalid "exec_mode".

func (*ServiceDefinition) NodeService 

func (s *ServiceDefinition) NodeService() *NodeService

func (*ServiceDefinition) Validate added in v1.2.0 

func (s *ServiceDefinition) Validate() error

Validate validates the service definition. This also calls the underlying Validate method on the NodeService.

NOTE(mitchellh): This currently only validates fields related to Connect and is incomplete with regards to other fields.

type ServiceDefinitionConnectProxy added in v1.2.0 

type ServiceDefinitionConnectProxy struct {
	Command   []string               `json:",omitempty"`

const (
	// ServiceKindTypical is a typical, classic Consul service. This is
	// represented by the absence of a value. This was chosen for ease of
	// backwards compatibility: existing services in the catalog would
	// default to the typical service.
	ServiceKindTypical ServiceKind = ""

	// ServiceKindConnectProxy is a proxy for the Connect feature. This
	// service proxies another service within Consul and speaks the connect
	// protocol.
	ServiceKindConnectProxy ServiceKind = "connect-proxy"
)

	ServiceProxyDestination string
	ServiceProxy            ConnectProxyConfig
	ServiceConnect          ServiceConnect

	RaftIndex
}

ServiceNode represents a node that is part of a service. ID, Address, TaggedAddresses, and NodeMeta are node-related fields that are always empty in the state store and are filled in on the way out by parseServiceNodes(). This is also why PartialClone() skips them, because we know they are blank already so it would be a waste of time to copy them.

func (*ServiceNode) IsSameService added in v1.3.0 

func (s *ServiceNode) IsSameService(other *ServiceNode) bool

IsSameService checks if one Service of a ServiceNode is the same as another, without looking at the Raft information or Node information (that's why we didn't call it IsEqual). This is useful for seeing if an update would be idempotent for all the functional parts of the structure. In a similar fashion as ToNodeService(), fields related to Node are ignored see ServiceNode for more information.

	// health checks (critical AND warning checks will cause a node to be
	// discarded)
	OnlyPassing bool

	// IgnoreCheckIDs is an optional list of health check IDs to ignore when
	// considering which nodes are healthy. It is useful as an emergency measure
	// to temporarily override some health check that is producing false negatives
	// for example.
	IgnoreCheckIDs []types.CheckID

	// Near allows the query to always prefer the node nearest the given
	// node. If the node does not exist, results are returned in their
	// normal randomly-shuffled order. Supplying the magic "_agent" value
	// is supported to sort near the agent which initiated the request.
	Near string

	// Tags are a set of required and/or disallowed tags. If a tag is in
	// this list it must be present. If the tag is preceded with "!" then
	// it is disallowed.
	Tags []string

	// NodeMeta is a map of required node metadata fields. If a key/value
	// pair is in this map it must be present on the node in order for the
	// service entry to be returned.
	NodeMeta map[string]string

	// Connect if true will filter the prepared query results to only
	// include Connect-capable services. These include both native services
	// and proxies for matching services. Note that if a proxy matches,
	// the constraints in the query above (Near, OnlyPassing, etc.) apply
	// to the _proxy_ and not the service being proxied. In practice, proxies
	// should be directly next to their services so this isn't an issue.
	Connect bool
}
