Functions

func NewConsulBackend

func NewConsulBackend(conf map[string]string, logger log.Logger) (physical.Backend, error)

NewConsulBackend constructs a Consul backend using the given API client and the prefix in the KV store.

Types

type ConsulBackend

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

ConsulBackend is a physical backend that stores data at specific prefix within Consul. It is used for most production situations as it allows Vault to run on multiple machines in a highly-available manner.

func (*ConsulBackend) Delete

func (c *ConsulBackend) Delete(key string) error

Delete is used to permanently delete an entry

func (*ConsulBackend) DetectHostAddr

func (c *ConsulBackend) DetectHostAddr() (string, error)

DetectHostAddr is used to detect the host address by asking the Consul agent

func (*ConsulBackend) Get

func (c *ConsulBackend) Get(key string) (*physical.Entry, error)

Get is used to fetch an entry

func (*ConsulBackend) HAEnabled

func (c *ConsulBackend) HAEnabled() bool

HAEnabled indicates whether the HA functionality should be exposed. Currently always returns true.

func (*ConsulBackend) List

func (c *ConsulBackend) List(prefix string) ([]string, error)

List is used to list all the keys under a given prefix, up to the next prefix.

func (*ConsulBackend) LockWith

func (c *ConsulBackend) LockWith(key, value string) (physical.Lock, error)

Lock is used for mutual exclusion based on the given key.

func (*ConsulBackend) NotifyActiveStateChange

func (c *ConsulBackend) NotifyActiveStateChange() error

func (*ConsulBackend) NotifySealedStateChange

func (c *ConsulBackend) NotifySealedStateChange() error

func (*ConsulBackend) Put

func (c *ConsulBackend) Put(entry *physical.Entry) error

Put is used to insert or update an entry

func (*ConsulBackend) RunServiceDiscovery

func (c *ConsulBackend) RunServiceDiscovery(waitGroup *sync.WaitGroup, shutdownCh physical.ShutdownChannel, redirectAddr string, activeFunc physical.ActiveFunction, sealedFunc physical.SealedFunction) (err error)

func (*ConsulBackend) Transaction

func (c *ConsulBackend) Transaction(txns []*physical.TxnEntry) error

Used to run multiple entries via a transaction

type ConsulLock

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

ConsulLock is used to provide the Lock interface backed by Consul

func (*ConsulLock) Lock

func (c *ConsulLock) Lock(stopCh <-chan struct{}) (<-chan struct{}, error)

func (*ConsulLock) Unlock

func (c *ConsulLock) Unlock() error

func (*ConsulLock) Value

func (c *ConsulLock) Value() (bool, string, error)
