type EtcdConfig

type EtcdConfig struct {
	InitialCluster      []string
	InitialClusterState string
	AdvertisePeerURLs   string
	Discovery           string
	Name                string
}

EtcdConfig is the result of the join algorithm, turned into etcd flags or env vars.

	discoveryURL, name, initialAdvertisePeerURLs string,
	fresh bool,
	clientPort, clusterSize int,
	strategy Strategy,
) (*EtcdConfig, error)

Join adds a new member depending on the strategy and returns a matching etcd configuration.
