Functions

func EtcdHealthCheck

func EtcdHealthCheck(data []byte) error

func GetEtcdVersion

func GetEtcdVersion(host string) (string, error)

GetEtcdVersion performs a version check against the provided Etcd server, returning the string response, and error (if any).

func IsEtcdNodeExist

func IsEtcdNodeExist(err error) bool

IsEtcdNodeExist returns true if and only if err is an etcd node already exist error.

func IsEtcdNotFound

func IsEtcdNotFound(err error) bool

IsEtcdNotFound returns true if and only if err is an etcd not found error.

func IsEtcdTestFailed

func IsEtcdTestFailed(err error) bool

IsEtcdTestFailed returns true if and only if err is an etcd write conflict.

func IsEtcdUnreachable

func IsEtcdUnreachable(err error) bool

IsEtcdUnreachable returns true if and only if err indicates the server could not be reached.

func IsEtcdWatchExpired

func IsEtcdWatchExpired(err error) bool

IsEtcdWatchExpired returns true if and only if err indicates the watch has expired.

func IsEtcdWatchStoppedByUser

func IsEtcdWatchStoppedByUser(err error) bool

IsEtcdWatchStoppedByUser returns true if and only if err is a client triggered stop.

func NewEtcdClientStartServerIfNecessary
