docker-mariadb-galera.service - stop command fails

[haraldkoch]

When I run sudo systemctl stop docker-mariadb-galera I get an error:

Mar 08 23:51:48 cluster1 systemd[1]: Stopping MariaDB with Galera Cluster...
Mar 08 23:51:48 cluster1 bash[23455]: Error response from daemon: No such container: mariadb-container-

This appears to be because in the ExecStop command that parses out a value for HOSTNUM, the variable substitution (with an empty value) happens before the parsing actually occurs.

The container still gets stopped on my machine; I think the ExecStop command probably isn't necessary at all. The docker command inside docker-mariadb-galera.sh runs in the foreground (no -d argument), so systemd is able to send it signals, and that causes docker to shut down the container.

Hi @haraldkoch sorry for the delay in responding.

I cannot reproduce the issue when running the VMs on Azure. Are you using the ARM template for Azure, or are you just using the cloud-config? What distribution are you using - CoreOS?

If you're not using the ARM templates for Azure, please make sure you review the notes here: https://github.com/EgoAleSum/mariadb-cluster#using-the-cloud-config-mode
The hostnames of the VMs must be mariadb-node-0 until mariadb-node-4.

Closing for now.
