That situation can happen in a couple of different ways:
* RHEL/CentOS does not start or enable the DB by default, you have to do so explicitly!
* DB was shut down manually or also updated at the same time as EGroupware
The [MariaDB/MySQL socket is bind-mounted into the egroupware container](https://github.com/EGroupware/build.opensuse.org/blob/master/server:eGroupWare/egroupware-docker-19.1/egroupware-docker/docker-compose.yml#L41) so db_host="localhost" continues to work.
> If the DB is not running and therefore the socket is not there when EGroupware container starts, Docker creates a directory with the same name on the host AND inside the container.
> Neither of them does recover automatically from that situation!
You have to manually fix it:
```
cd /etc/egroupware-docker
docker-compose stop egroupware
docker-compose rm -f egroupware
rm -rf /var/{run,lib}/mysql*/mysql*.sock
systemctl start mariadb # or mysqld
systemctl enable mariadb # only necessary for RHEL/CentOS not doing so by installing the DB
systemctl status mariadb
docker-compose up -d
```
