Docker Issues

Docker Issues - storage full

• Storage full on submission box

  • there can be so many error patterns in shortage of storage

Add error

// Some code

In this case, a common problem is that multiple unused docker containers remain on the submission box. A simple solution is to prune unused containers:

docker system prune

or belows:

// Remove all stopped containers
% docker rm $(docker ps -a -q)

// or Remove all containers
% docker rm -f $(docker ps -a -q)

docker volume could not be changed even if the container was updated and relaunched

• Docker volume will not be changed and remained once it was created (except mount with -v). That is to say "exists independently".

• This is observed as well in using docker-compose. If you define and use volumes: in docker-compose.yml file, be cautious that the created volume will not be removed after invoking docker compose down .

• a workaround is to delete the docker volume beforehand

# Remove volumes
% docker volume rm <specified volume name>
# or 
% docker volume prune
