      The mysql addon fails to start sometimes and this results in mysql based apps not working.

      First check the status of the mysql addon using docker logs -f mysql. If it says Waiting for MySQL to come up, then that is the root the problem.

      docker exec -ti mysql /bin/bash
      root@f483661487a5:/# mysqld --datadir="${MYSQL_DATA_DIR}" --user=mysql
      mysqld: error while loading shared libraries: libaio.so.1: cannot stat shared object: Permission denied
      

      This appears to be something related to docker. There are some existing bug reports/pages for this:

      • https://stackoverflow.com/questions/22473830/docker-and-mysql-libz-so-1-cannot-open-shared-object-file-permission-denied
      • https://github.com/moby/moby/issues/7512
      • https://github.com/moby/moby/issues/5430

      Not sure what caused the problem but simply recreating the addon infrastructure fixed it (this essentially recreates the docker containers). This can done by:

      • Bump up the patch version in /home/yellowtent/platformdata/INFRA_VERSION. This has to be done very carefully. Please do not do this without a complete backup.
      • systemctl restart cloudron.target

        Is this affecting new docker builds (cloudron build )?

          In another server instance hit by https://forum.cloudron.io/topic/1382/error-for-multiple-apps/12, recreating docker containers did not help. I even disabled apparmor altogether using sudo systemctl stop apparmor and sudo systemctl disable apparmor. We tried server restart as well and that didn't help either.

          After disabling apparmor, I saw that mysqld would just quit without showing any error message or log output 😞 As a final thing, I just ended up moving platformdata/mysql to mysql-old and recreated containers again. That made mysql come up and then we restored all the apps.

          Still a bit crazy/worrying that we hit this bug atleast twice now and there is no clear resolution.
