Best way to clean up Docker data safely:

docker system prune -a --volumes

Networks:

---

Remove all Networks:

docker network prune -f

or

docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

Volumes:

---

Remove all dangling volumes:

docker volume rm $(docker volume ls -qf dangling=true)

Images:

---

Remove only dangling images:

docker rmi $(docker images -f dangling=true -q)

Remove all images:

docker rmi $(docker images -f -a -q)

Remove images with pattern:

docker images -a | grep "pattern" | awk '{print $3}' | xargs docker rmi

List dockerfile commands

docker history --no-trunc <image>

Containers:

---

Remove all stopped containers:

docker rm $(docker ps -a -q)

or

docker container prune

Docker Run and remove (my-container) container when stopped:

docker run --rm -it my-docker 

Remove all containers forcefully:

docker rm --force $(docker ps -a -q)

or

docker container prune -f

Exec inside a container

docker exec -it <container_name|contianer_id> bash

Registry:

---

Acessing Registry (v2) with curl:

Note: for protected registry, basic auth argument username:password.

List repositories:

Docker registry is running in a local container.

curl -X GET http://localhost:5000/v2/_catalog

List tags from a repository:

curl -X GET http://localhost:5000/v2/<repository>/tags/list
