Docker needs daily or at least weekly maintenance with the help of the following command:

docker system prune -f

You should probably put that one on a systemd timer just in case.

docker image prune -a

docker system df

docker ps -a

docker ps --format "table {{.Names}}\t{{.Status}}\t \
  {{.Networks}}\t{{.Ports}}\t{{.Size}}"

docker logs -f container_name

docker network inspect network_name  

docker container inspect container_name  

docker network ls

docker network prune

docker attach mybb_mybb_1 

docker history mybb/mybb:latest 

docker exec -it mybb_mybb_1 /bin/sh

Stopping containers with specific name

docker container stop $(docker container ls -q --filter name=myapp*)

dtags () {
    local image="${1}"

    wget -q https://registry.hub.docker.com/v1/repositories/"${image}"/tags -O - \
        | tr -d '[]" ' | tr '}' '\n' | awk -F: '{print $3}'
}
