I can't reproduce, even with 700 permissions. Can you give all the commands you ran and any relevant files or logs for reproducing the issue? $ adduser -u 1337 test
$ mkdir mysql
$ chmod 700 mysql
$ docker run -d -e MYSQL_ROOT_PASSWORD=pass --name mariadb --user 1337 -v "$PWD"/mysql:/var/lib/mysql mariadb

Uh oh!
There was an error while loading. Please reload this page.
I was running mariadb docker container (image mariadb:10.4.12) by specifying
--user UID:GID -v /var/lib/mysql:/var/lib/mysql
and the ownership of /var/lib/mysql is UID:GID. The command was running as a non-root user, but failed with the error:MySQL docker image supports this, see https://hub.docker.com/_/mysql,
Running as an arbitrary user
.I also found #59, seems it should support this feature, is there anything I am missing?
