Golang CreateEndpoints Examples

Example #1

File: etcd.go Project: sanimej/libkv

// New creates a new Etcd client given a list
// of endpoints and an optional tls config
func New(addrs []string, options *store.Config) (store.Store, error) {
	s := &Etcd{}

	entries := store.CreateEndpoints(addrs, "http")

	// Set options
	if options != nil {
		if options.TLS != nil {
			s.setTLS(options.TLS)
		}
		if options.ConnectionTimeout != 0 {
			s.setTimeout(options.ConnectionTimeout)

	}

	// Periodic SyncCluster
	go func() {
		for {
			s.client.SyncCluster()
			time.Sleep(periodicSync)

	}()

	return s, nil
}

Example #3

File: etcd.go Project: nixuw/docker

// SetTLS sets the tls configuration given a tls.Config scheme
