Thanks for everyone's hard work, but there's still be a problem with the latest bitmani/mariadb image,
"Error executing 'postInstallation': EACCES: permission denied, mkdir '/bitnami/mariadb" ,
"chown 1001:1001 -R /mariadb_data " solved the problem.

@l50 it's usually better to use restart: unless-stopped instead of restart: always

This will restart the container on a reboot or power failure, but will not automatically restart it if stopped manually.
