Unable to see the tables inside a docker container

Question

Following is the code inside container for the sql:

mysql:
    image: mariadb
    command: --max_allowed_packet=32505856
    environment:
    - MYSQL_ROOT_PASSWORD=root
    - MYSQL_USER=abc
    - MYSQL_PASSWORD=xyz.123
    - MYSQL_DATABASE=abc
    - MYSQL_ALLOW_EMPTY_PASSWORD=true
    restart: always
    ports:
    - 3306:3306
    volumes:
    # Using volume mount to mimic prod setup
    - /tmp/mysql:/vol_mount/

I have been trying to access the database to view tables but have been unable to do so thus far.

I have tried running commands like:

docker exec -it container_name mysql -uabc -p

and then have tried bot 'root' and 'xyz.123' when prompted to enter password. But then I get an error like

"ERROR 1045 (28000): Access denied for user 'abc'@'2001:db8:1::a7' (using password: YES)"

I need to know the commands that will allow for me to access the DB and view tables. Thanks.

This will open your mysql console with user root:

docker exec -ti mariadb-test sh -c 'mysql -uroot -p${MYSQL_ROOT_PASSWORD}'

Please note that I named the container mariadb-test in the compose file you can use a different name if you like.

Similarly you can connect with used abc :

docker exec -ti mariadb-test sh -c 'mysql -uabc -p${MYSQL_PASSWORD}'

UPDATE:

Run the following to check the environment variables inside your container. They should match the values provided in the docker-compose.yml.

docker exec -ti mariadb-test sh -c 'env | grep MYSQL'

Since in my solution you don't even have to type the password, it should work anyway. Please try to start from a clean state: bring down all the containers, remove volumes and restart the services with this docker-compose file.
