Functions

func Asset 

func Asset(name string) ([]byte, error)

Types

type Agent 

type Agent struct {

	// Output sink for logs
	LogOutput io.Writer

	// In-memory sink used for collecting metrics
	MemSink *metrics.InmemSink

	// state stores a local representation of the node,
	// services and checks. Used for anti-entropy.
	State *local.State

	InterruptStartCh chan struct{}
	// contains filtered or unexported fields
}

Agent is the long running process that is run on every machine. It exposes an RPC interface that is used by the CLI to control the agent. The agent runs the query interfaces like HTTP, DNS, and RPC. However, it can run in either a client, or server mode. In server mode, it runs a full Consul server. In client-only mode, it only forwards requests to other Consul servers.

func New

New verifies the configuration given has a Datacenter and DataDir configured, and maps the remaining config fields to fields on the Agent.

func (*Agent) ConnectAuthorize added in v1.3.0 

func (a *Agent) ConnectAuthorize(token string,
	req *structs.ConnectAuthorizeRequest) (allowed bool, reason string, m *cache.ResultMeta, err error)

ConnectAuthorize implements the core authorization logic for Connect. It's in a separate agent method here because we need to re-use this both in our own HTTP API authz endpoint and in the gRPX xDS/ext_authz API for envoy.

The ACL token and the auth request are provided and the auth decision (true means authorized) and reason string are returned.

If the request input is invalid the error returned will be a BadRequestError, if the token doesn't grant necessary access then an acl.ErrPermissionDenied error is returned, otherwise error indicates an unexpected server failure. If access is denied, no error is returned but the first return value is false.

	fn func(ws memdb.WatchSet) (string, interface{}, error)) (string, interface{}, error)

LocalBlockingQuery performs a blocking query in a generic way against local agent state that has no RPC or raft to back it. It uses `hash` parameter instead of an `index`. `alwaysBlock` determines whether we block if the provided hash is empty. Callers like the AgentService endpoint will want to return the current result if a hash isn't provided. On the other hand, for cache notifications we always want to block. This avoids an empty first response.

}

type ServiceManager added in v1.5.0 

type ServiceManager struct {
	// contains filtered or unexported fields
}

The ServiceManager is a layer for service registration in between the agent and the local state. Any services must be registered with the ServiceManager, which then maintains a long-running watch of any globally-set service or proxy configuration that applies to the service in order to register the final, merged service configuration locally in the agent state.

func NewServiceManager added in v1.5.0 

func NewServiceManager(agent *Agent) *ServiceManager

func (*ServiceManager) AddService added in v1.5.0 

func (s *ServiceManager) AddService(req *addServiceRequest) error

AddService will (re)create a serviceConfigWatch on the given service. For each call of this function the first registration will happen inline and will read the merged global defaults for the service through the agent cache (regardless of whether or not the service was already registered). This lets validation or authorization related errors bubble back up to the caller's RPC inline with their request. Upon success a goroutine will keep this updated in the background.

If waitForCentralConfig=true is used, the initial registration blocks on fetching the merged global config through the cache. If false, no such RPC occurs and only the previousDefaults are used.

persistServiceConfig controls if the INITIAL registration will result in persisting the service config to disk again. All background updates will always persist.

service, chkTypes, persist, token, replaceExistingChecks, and source are basically pass-through arguments to Agent.addServiceInternal that follow the semantics there. The one key difference is that the service provided will be merged with the global defaults before registration.

NOTE: the caller must hold the Agent.stateLock!

func (*ServiceManager) RemoveService added in v1.5.0 

func (s *ServiceManager) RemoveService(serviceID structs.ServiceID)

NOTE: the caller must hold the Agent.stateLock!

func (*ServiceManager) Start added in v1.6.2 

func (s *ServiceManager) Start()

Start starts a background worker goroutine that writes back into the Agent state. This only exists to keep the need to lock the agent state lock out of the main AddService/RemoveService codepaths to avoid deadlocks.

func (*ServiceManager) Stop added in v1.6.2 

func (s *ServiceManager) Stop()

Stop forces all background goroutines to terminate and blocks until they complete.

NOTE: the caller must NOT hold the Agent.stateLock!

type ServiceSummary 

type ServiceSummary struct {
	Kind            structs.ServiceKind `json:",omitempty"`
	Name            string
	Tags            []string
	Nodes           []string
	ChecksPassing   int
	ChecksWarning   int
	ChecksCritical  int
	ExternalSources []string

	structs.EnterpriseMeta
	// contains filtered or unexported fields
}

ServiceSummary is used to summarize a service

type TestAgent 

type TestAgent struct {
	// Name is an optional name of the agent.
	Name string

	HCL string

	// Config is the agent configuration. If Config is nil then
	// TestConfig() is used. If Config.DataDir is set then it is
	// the callers responsibility to clean up the data directory.
	// Otherwise, a temporary data directory is created and removed
	// when Shutdown() is called.
	Config *config.RuntimeConfig

	// LogOutput is the sink for the logs. If nil, logs are written
	// to os.Stderr.
	LogOutput io.Writer

	// DataDir is the data directory which is used when Config.DataDir
	// is not set. It is created automatically and removed when
	// Shutdown() is called.
	DataDir string

	// Key is the optional encryption key for the LAN and WAN keyring.
	Key string

	// UseTLS, if true, will disable the HTTP port and enable the HTTPS
	// one.
	UseTLS bool

	// Agent is the embedded consul agent.
	// It is valid after Start().
	*Agent
	// contains filtered or unexported fields
}

TestAgent encapsulates an Agent with a default configuration and startup procedure suitable for testing. It panics if there are errors during creation or startup instead of returning errors. It manages a temporary data directory which is removed after shutdown.

func NewTestAgent 

func NewTestAgent(t *testing.T, name string, hcl string) *TestAgent

NewTestAgent returns a started agent with the given name and configuration. It fails the test if the Agent could not be started. The caller should call Shutdown() to stop the agent and remove temporary directories.

func NewTestAgentWithFields added in v1.6.1 

func NewTestAgentWithFields(t *testing.T, start bool, ta TestAgent) *TestAgent

NewTestAgentWithFields takes a TestAgent struct with any number of fields set, and a boolean 'start', which indicates whether or not the TestAgent should be started. If no LogOutput is set, it will automatically be set to testutil.TestWriter(t). Name will default to t.Name() if not specified.

const (
	TranslateAddressAcceptDomain TranslateAddressAccept = 1 << iota
	TranslateAddressAcceptIPv4
	TranslateAddressAcceptIPv6

type UserEvent struct {
	// ID of the user event. Automatically generated.
	ID string

	// Name of the event
	Name string `codec:"n"`

	// Optional payload
	Payload []byte `codec:"p,omitempty"`

	// NodeFilter is a regular expression to filter on nodes
	NodeFilter string `codec:"nf,omitempty"`

	// ServiceFilter is a regular expression to filter on services
	ServiceFilter string `codec:"sf,omitempty"`

	// TagFilter is a regular expression to filter on tags of a service,
	// must be provided with ServiceFilter
	TagFilter string `codec:"tf,omitempty"`

	// Version of the user event. Automatically generated.
	Version int `codec:"v"`
