From readme of [phpmyadmin/docker](https://github.com/phpmyadmin/docker)
> Note that since phpMyAdmin has been accepted in to the official DockerHub repository, you can use either that or this older phpMyAdmin repository for your Docker installation. This is maintained as a courtesy to users who have not migrated.
P.S. version from `phpmyadmin` supports `caching_sha2_password`, that makes me happy :)
