Und es gibt viele andere Images für verschiedene Dinge wie Datenbanken, zum Beispiel für:

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>
* <a href="https://hub.docker.com/_/mysql" class="external-link" target="_blank">MySQL</a>

Vous pouvez utiliser <a href="https://www.docker.com/" class="external-link" target="_blank">**Docker**</a> pour le déploiement. Il présente plusieurs avantages comme la sécurité, la réplicabilité, la simplicité de développement, etc.

Si vous utilisez Docker, vous pouvez utiliser l'image Docker officielle :

			g := Granted{index: index}
			if c == nil {
				log("dsync: nil locker\n")
				ch <- g
				return
			}

			var locked bool
			var err error
			if isReadLock {
				if locked, err = c.RLock(netLockCtx, args); err != nil {
					log("dsync: Unable to call RLock failed with %s for %#v at %s\n", err, args, c)
				}
			} else {
				if locked, err = c.Lock(netLockCtx, args); err != nil {
