Constants ¶
const ( // ACLBootstrapInit is used to perform a scan for existing tokens which // will decide whether bootstrapping is allowed for a cluster. This is // initiated by the leader when it steps up, if necessary. ACLBootstrapInit = "bootstrap-init" // ACLBootstrapNow is used to perform a one-time ACL bootstrap operation on // a cluster to get the first management token.

These are serialized between Consul servers and stored in Consul snapshots, so entries must only ever be added.
const ( // IgnoreUnknownTypeFlag is set along with a MessageType // to indicate that the message type can be safely ignored // if it is not recognized.

Variables ¶
var ( ErrNoLeader = errors.New(errNoLeader) ErrNoDCPath = errors.New(errNoDCPath) ErrNoServers = errors.New(errNoServers) ErrNotReadyForConsistentReads = errors.New(errNotReadyForConsistentReads) ErrSegmentsNotSupported = errors.New(errSegmentsNotSupported) ErrRPCRateExceeded = errors.New(errRPCRateExceeded) )
var ACLBootstrapNotAllowedErr = errors.New("ACL bootstrap no longer allowed")
ACLBootstrapNotAllowedErr is returned once we know that a bootstrap can no longer be done since the cluster was bootstrapped, or a management token was created manually.
var ACLBootstrapNotInitializedErr = errors.New("ACL bootstrap not initialized, need to force a leader election and ensure all Consul servers support this feature")
ACLBootstrapNotInitializedErr is returned when a bootstrap is attempted but we haven't yet initialized ACL bootstrap. It provides some guidance to operators on how to proceed.

func (CheckServiceNodes) FilterIgnore ¶ added in v1.0.7
func (nodes CheckServiceNodes) FilterIgnore(onlyPassing bool, ignoreCheckIDs []types.CheckID) CheckServiceNodes
FilterIgnore removes nodes that are failing health checks just like Filter. It also ignores the status of any check with an ID present in ignoreCheckIDs as if that check didn't exist. Note that this returns the filtered results AND modifies the receiver for performance.
func (CheckServiceNodes) Shuffle ¶
func (nodes CheckServiceNodes) Shuffle()
Shuffle does an in-place random shuffle using the Fisher-Yates algorithm.
type CheckType ¶
type CheckType struct { CheckID types.CheckID Name string Status string Notes string ScriptArgs []string HTTP string Header map[string][]string Method string TCP string Interval time.Duration AliasNode string AliasService string DockerContainerID string Shell string GRPC string GRPCUseTLS bool TLSSkipVerify bool Timeout time.Duration TTL time.Duration // DeregisterCriticalServiceAfter, if >0, will cause the associated // service, if any, to be deregistered if this check is critical for // longer than this duration. DeregisterCriticalServiceAfter time.Duration }
CheckType is used to create either the CheckMonitor or the CheckTTL. The following types are supported: Script, HTTP, TCP, Docker, TTL, GRPC, Alias. Script, HTTP, Docker, TCP and GRPC all require Interval.

This // is currently the URI SAN from the TLS client certificate. // // ClientCertSerial is a colon-hex-encoded of the serial number for // the requesting client cert. This is used to check against revocation // lists. ClientCertURI string ClientCertSerial string }
ConnectAuthorizeRequest is the structure of a request to authorize a connection.
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{} // 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"` BindPort int `mapstructure:"bind_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 ConsulCAProviderConfig ¶ added in v1.2.0
type ConsulCAProviderConfig struct { CommonCAProviderConfig `mapstructure:",squash"` PrivateKey string RootCert string RotationPeriod time.Duration }
type Coordinate ¶
type Coordinate struct { Node string Segment string Coord *coordinate.Coordinate }

func (*DeregisterRequest) RequestDatacenter ¶
func (r *DeregisterRequest) RequestDatacenter() string
type DirEntries ¶
type DirEntries []*DirEntry

type EventFireRequest ¶
type EventFireRequest struct { Datacenter string Name string Payload []byte // Not using WriteRequest so that any server can process // the request. It is a bit unusual... QueryOptions }
EventFireRequest is used to ask a server to fire a Serf event. It is a bit odd, since it doesn't depend on the catalog or leader. Any node can respond, so it's not quite like a standard write request. This is used only internally.
func (*EventFireRequest) RequestDatacenter ¶
func (r *EventFireRequest) RequestDatacenter() string
type EventFireResponse ¶
type EventFireResponse struct {
QueryMeta
}
EventFireResponse is used to respond to a fire request.

HealthCheck represents a single check on a given node
func (*HealthCheck) Clone ¶
func (c *HealthCheck) Clone() *HealthCheck
Clone returns a distinct clone of the HealthCheck.
func (*HealthCheck) IsSame ¶
func (c *HealthCheck) IsSame(other *HealthCheck) bool
IsSame checks if one HealthCheck is the same as another, without looking at the Raft 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.
type HealthCheckDefinition ¶ added in v1.0.1
type HealthCheckDefinition struct { HTTP string `json:",omitempty"` TLSSkipVerify bool `json:",omitempty"` Header map[string][]string `json:",omitempty"` Method string `json:",omitempty"` TCP string `json:",omitempty"` Interval api.ReadableDuration `json:",omitempty"` Timeout api.ReadableDuration `json:",omitempty"` DeregisterCriticalServiceAfter api.ReadableDuration `json:",omitempty"` }

ActiveRootID string // TrustDomain is the identification root for this Consul cluster. All // certificates signed by the cluster's CA must have their identifying URI in // this domain. // // This does not include the protocol (currently spiffe://) since we may // implement other protocols in future with equivalent semantics. It should be // compared against the "authority" section of a URI (i.e. host:port). // // NOTE(banks): Later we may support explicitly trusting external domains // which may be encoded into the CARoot struct or a separate list but this // domain identifier should be immutable and cluster-wide so deserves to be at // the root of this response rather than duplicated through all CARoots that // are not externally trusted entities. TrustDomain string // Roots is a list of root CA certs to trust. Roots []*CARoot // QueryMeta contains the meta sent via a header. We ignore for JSON // so this whole structure can be returned. QueryMeta `json:"-"` }

type Intention struct { // ID is the UUID-based ID for the intention, always generated by Consul. ID string // Description is a human-friendly description of this intention. // It is opaque to Consul and is only stored and transferred in API // requests. Description string // SourceNS, SourceName are the namespace and name, respectively, of // the source service. Either of these may be the wildcard "*", but only // the full value can be a wildcard. Partial wildcards are not allowed. // The source may also be a non-Consul service, as specified by SourceType. // // DestinationNS, DestinationName is the same, but for the destination // service. The same rules apply. The destination is always a Consul // service. SourceNS, SourceName string DestinationNS, DestinationName string // SourceType is the type of the value for the source. SourceType IntentionSourceType // Action is whether this is a whitelist or blacklist intention. Action IntentionAction // DefaultAddr, DefaultPort of the local listening proxy (if any) to // make this connection. DefaultAddr string DefaultPort int // Meta is arbitrary metadata associated with the intention. This is // opaque to Consul but is served in API responses. Meta map[string]string // Precedence is the order that the intention will be applied, with // larger numbers being applied first. This is a read-only field, on // any intention update it is updated. Precedence int // CreatedAt and UpdatedAt keep track of when this record was created // or modified. CreatedAt, UpdatedAt time.Time `mapstructure:"-"` RaftIndex }
