Images

Build a named image from a Dockerfile in the current directory:

docker build -t name .

Volumes

Get names of orphaned docker volume containers:

docker volume ls -qf dangling=true

and remove:

docker volume rm $name

Backup stuff from inside a named volume container:

docker run --rm --volumes-from dbstore -v $(pwd):/backup ubuntu tar cvf /backup/backup.tar /dbdata

and then restore:

docker run -v /dbdata --name dbstore2 ubuntu /bin/bash
docker run --rm --volumes-from dbstore2 -v $(pwd):/backup ubuntu bash -c "cd /dbdata && tar xvf /backup/backup.tar --strip 1"

Images

Clean images:

docker rmi `docker images -q -f "dangling=true"`

Remove all untagged images:

docker rmi `docker images | grep "\s<none>" | awk '{print $3}'`
# or
docker rmi $(docker images -q --filter "dangling=true")

Stop all

docker stop $(docker ps -a -q)

Forcefully delete last 16 images. RIP my images when I ran this a second time by accident.

docker rmi -f `docker images --format "{{.ID}}" | tail -n +1 | head -n 16`
