Services, system deployment, update |
Service fails to start during system deployment and updateRarely, a system deployment, service management operation, or system update may fail because a service fails to start. When this happens, the Administration App is inaccessible from the instance where the failure occurred. The logs in the watchdog-service log directory contain this error: Error response from daemon: Conflict. The name "<service-name>" is already in use by container <Docker-container-id>. You have to remove (or rename) that container to be able to reuse that name. WorkaroundRestart the Docker service on the instance where the service failed to start. For example, if you are using systemd to run Docker, run: systemctl restart docker After restarting Docker, retry the system deployment, service management operation, or system update. |
