Functions

func GetCurrentNodesFromDiscovery

func GetCurrentNodesFromDiscovery(token string, size int) ([]string, error)

Get the nodes that have registered with the discovery service. We only want to return the number of nodes that are expected for the etcd cluster size. Etcd will not allow more etcd servers to start unless the AddMember api is called. Here we will ignore any nodes that have registered beyond the expected size. It is important to return the nodes with the lowest index for consistent behavior in the cluster.

func GetEtcdClients

func GetEtcdClients(configDir, token, ipAddr, nodeID string) ([]string, error)

GetEtcdClients bootstraps an embedded etcd instance and returns a list of current etcd cluster's client URLs. (entrypoint, when it's used as a library)

Types

type Config

type Config struct {
	InstanceName        string
	ListenPeerURLs      []url.URL
	ListenClientURLs    []url.URL
	AdvertisePeerURLs   []url.URL
	AdvertiseClientURLs []url.URL
	DataDir             string
	URLsMap             types.URLsMap
}

Config holds the configuration of elastic etcd.

func CopyConfig

func CopyConfig(conf *Config) Config

CopyConfig returns a copy of given etcd config

func GenerateConfigFromExistingCluster

func GenerateConfigFromExistingCluster(Context EtcdMgrContext, configDir, ipAddr, nodeID string) (*Config, error)

GenerateConfigFromExistingCluster automatically generates a config for joining an existing cluster

type Context

type Context struct {
	ClusterToken string
}

func (*Context) Client

func (e *Context) Client(initialNodes []string) (client.Client, error)

func (*Context) KeysAPI

func (e *Context) KeysAPI() (client.KeysAPI, error)

func (*Context) Members

func (e *Context) Members() ([]string, types.URLsMap, error)

func (*Context) MembersAPI

func (e *Context) MembersAPI() (client.MembersAPI, error)

MembersAPI returns an instance of MembersAPI for the current etcd cluster

type EmbeddedEtcd

type EmbeddedEtcd struct {
	Server *etcdserver.EtcdServer
	// contains filtered or unexported fields
}

EmbeddedEtcd represents an instance of etcd server.

func (*EmbeddedEtcd) Destroy

func (ee *EmbeddedEtcd) Destroy(conf *Config) error

Destroy wipes out the current instance of etcd and makes the necessary cleanup.

func (*EmbeddedEtcd) InitializeListeners

func (ee *EmbeddedEtcd) InitializeListeners() error

type EmbeddedEtcdFactory

type EmbeddedEtcdFactory struct {
}

func (*EmbeddedEtcdFactory) NewEmbeddedEtcd

func (e *EmbeddedEtcdFactory) NewEmbeddedEtcd(token string, conf *Config, newCluster bool) (*EmbeddedEtcd, error)

NewEmbeddedEtcd creates a new inproc instance of etcd.

type EtcdFactory

type EtcdFactory interface {
	NewEmbeddedEtcd(token string, conf *Config, newCluster bool) (*EmbeddedEtcd, error)
}

type EtcdMgrContext

type EtcdMgrContext interface {
	Client(initialNodes []string) (client.Client, error)
	MembersAPI() (client.MembersAPI, error)
	KeysAPI() (client.KeysAPI, error)
	Members() ([]string, types.URLsMap, error)
}

type Machine

type Machine struct {
	client.Member
}
