Functions

func EtcdClient

func EtcdClient(etcdClientInfo configapi.EtcdConnectionInfo) (*etcdclient.Client, error)

EtcdClient creates an etcd client based on the provided config.

func GetAndTestEtcdClient

func GetAndTestEtcdClient(etcdClientInfo configapi.EtcdConnectionInfo) (*etcdclient.Client, error)

GetAndTestEtcdClient creates an etcd client based on the provided config. It will attempt to connect to the etcd server and block until the server responds at least once, or return an error if the server never responded. TODO: switch this function to use EtcdHelper.

func MakeNewEtcdClient

func MakeNewEtcdClient(etcdClientInfo configapi.EtcdConnectionInfo) (newetcdclient.Client, error)

MakeNewEtcdClient creates an etcd client based on the provided config.

func NeverRetryOnFailure

func NeverRetryOnFailure(cluster *etcdclient.Cluster, numReqs int, lastResp http.Response, err error) error

NeverRetryOnFailure is a retry function for the etcdClient. If there's only one machine, master election doesn't make much sense, so we don't bother to retry, we simply dump the failure and return the error directly.

func TestEtcdClient

func TestEtcdClient(etcdClient *etcdclient.Client) error

TestEtcdClient verifies a client is functional. It will attempt to connect to the etcd server and block until the server responds at least once, or return an error if the server never responded.

func TestNewEtcdClient

func TestNewEtcdClient(etcdClient newetcdclient.Client) error

TestEtcdClient verifies a client is functional. It will attempt to connect to the etcd server and block until the server responds at least once, or return an error if the server never responded.
