Docker Tips

container.sh

# remove all stopped containers!
docker container prune

history.sh

# show layers info about a a image
docker history <image>

notes

If your container needs to write a lot of data, you should consider using a data volume.

run.sh

# remove container when exited
docker run --rm <>

# run in background 
docker run -d <>

# -t allocate a psudo-tty so no immediate exit( hence no stopped container)
docker run -d -t ubuntu

volume.sh

# remove dangling volumes( volumes attached to no current running container)

docker volume rm $(docker volume ls -f dangling=true -q)
