Types

type Config

type Config struct {
	EnablePersistence     bool
	DataDir               string
	ACLDefaultToken       string
	ACLAgentToken         string
	ACLAgentRecoveryToken string
	ACLReplicationToken   string

	EnterpriseConfig
}

Config used by Store.Load, which includes tokens and settings for persistence.

type EnterpriseConfig

type EnterpriseConfig struct {
}

type Logger

type Logger interface {
	Warn(msg string, args ...interface{})
}

Logger used by Store.Load to report warnings.

type Notifier

type Notifier struct {
	Ch <-chan struct{}
	// contains filtered or unexported fields
}

Notifier holds the channel used to notify a watcher of token updates as well as some internal tracking information to allow for deregistering the notifier.

type Store

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

Store is used to hold the special ACL tokens used by Consul agents. It is designed to update the tokens on the fly, so the token store itself should be plumbed around and used to get tokens at runtime, don't save the resulting tokens.

func (*Store) AgentRecoveryToken

func (t *Store) AgentRecoveryToken() string

func (*Store) AgentRecoveryTokenAndSource

func (t *Store) AgentRecoveryTokenAndSource() (string, TokenSource)

func (*Store) AgentToken

func (t *Store) AgentToken() string

AgentToken returns the best token to use for internal agent operations.

func (*Store) AgentTokenAndSource

func (t *Store) AgentTokenAndSource() (string, TokenSource)

AgentToken returns the best token to use for internal agent operations.

func (*Store) IsAgentRecoveryToken

func (t *Store) IsAgentRecoveryToken(token string) bool

IsAgentRecoveryToken checks to see if a given token is the agent recovery token. This will never match an empty token for safety.

func (*Store) Load

func (t *Store) Load(cfg Config, logger Logger) error

Load tokens from Config and optionally from a persisted file in the cfg.DataDir. If a token exists in both the persisted file and in the Config a warning will be logged and the persisted token will be used.

Failures to load the persisted file will result in loading tokens from the config before returning the error.

func (*Store) Notify

func (t *Store) Notify(kind TokenKind) Notifier

Notify will set up a watch for when tokens of the desired kind is changed

func (*Store) ReplicationToken

func (t *Store) ReplicationToken() string

ReplicationToken returns the replication token.

func (*Store) ReplicationTokenAndSource

func (t *Store) ReplicationTokenAndSource() (string, TokenSource)

ReplicationToken returns the replication token.

func (*Store) StopNotify

func (t *Store) StopNotify(n Notifier)

StopNotify stops the token store from sending notifications to the specified notifiers chan

func (*Store) UpdateAgentRecoveryToken

func (t *Store) UpdateAgentRecoveryToken(token string, source TokenSource) bool

UpdateAgentRecoveryToken replaces the current agent recovery token in the store. Returns true if it was changed.

func (*Store) UpdateAgentToken

func (t *Store) UpdateAgentToken(token string, source TokenSource) bool

UpdateAgentToken replaces the current agent token in the store. Returns true if it was changed.

func (*Store) UpdateReplicationToken

func (t *Store) UpdateReplicationToken(token string, source TokenSource) bool

UpdateReplicationToken replaces the current replication token in the store. Returns true if it was changed.

func (*Store) UpdateUserToken

func (t *Store) UpdateUserToken(token string, source TokenSource) bool

UpdateUserToken replaces the current user token in the store. Returns true if it was changed.

func (*Store) UserToken

func (t *Store) UserToken() string

UserToken returns the best token to use for user operations.

func (*Store) UserTokenAndSource

func (t *Store) UserTokenAndSource() (string, TokenSource)

UserToken returns the best token to use for user operations.

func (*Store) WithPersistenceLock

func (t *Store) WithPersistenceLock(f func() error) error

WithPersistenceLock executes f while hold a lock. If f returns a nil error, the tokens in Store will be persisted to the tokens file. Otherwise no tokens will be persisted, and the error from f will be returned.

The lock is held so that the writes are persisted before some other thread can change the value.

type TokenKind

type TokenKind int

const (
	TokenKindAgent TokenKind = iota
	TokenKindAgentRecovery
	TokenKindUser
	TokenKindReplication
)

type TokenSource

type TokenSource bool

const (
	TokenSourceConfig TokenSource = false
	TokenSourceAPI    TokenSource = true
)
