docker run -d --name mariadb-test -e MYSQL_ROOT_PASSWORD=secret mariadb

docker ps

docker stop mariadb-test

docker logs mariadb-test

docker inspect mariadb-test

docker inspect -f '{{ .Mounts }}' mariadb-test

docker volume inspect d19f5b86...

docker system df -v

docker exec -it mariadb-test mysql -u root -p

OCI runtime exec failed: exec failed: unable to start container process: exec: "mysql": executable file not found in $PATH: unknown

For newer MariaDB container versions, the mysql executable does not exist any more. Replace mysql with mariadb to fix the issue

docker exec -it mariadb-test mariadb -u root -p

docker exec -it mariadb-test /bin/bash

mariadb --version
