On the test machine, this didn't remove any images.ĭocker image prune -a removes all images not used by containers. We can delete or remove all containers with a single command only.
docker stopWe have to first stop the container and delete it. This command also requires us to enter y and press Enter to proceed: WARNING! This will remove all dangling images. As we tried deleting a Container which was in running state, so the docker daemon throws an error. docker image prune removes these dangling images: docker image prune

If no other Docker image extended alpine:3.12, then Docker would consider alpine:3.12 a so-called “dangling image”: A once implicitly downloaded image that's now not needed anymore. Now let's say we removed the PostgreSQL 13 beta 2 image. We don't see these implicitly downloaded images with docker image ls. That's why Docker implicitly downloaded alpine:3.12 when we pulled the beta 2 image at first.
docker rm#Docker remove container on close how to#
Let's look at the top of the Dockerfile for the PostgreSQL beta 2 image to see what image it's extending: FROM alpine:3.12 How to removed the stopped / Exited docker container Now to remove the container completely from the system we need to use docker rm command i.e. Our Docker images extend other images to gain their functionality, just as Java classes extend other Java classes. Now we need need to discuss image relationships briefly. So on the test machine, this removed one stopped container. If you want to start container on boot just add a schedule task: Create -> Triggered Task -> User-defined Script.

This is not recommended because it sends kill command and your container might not save its state. With this, you can remove a running container: docker rm -f containeridorname.

#Docker remove container on close password#
We set secr3t as the password for the database root user because the PostgreSQL container won't start without one: docker run -d -e POSTGRES_PASSWORD=secr3t postgres:13-beta2-alpineĭocker ps -format 'table ' | grep '^postgres:13-beta' Docker gives you the -f option to force remove a container. Let's start a container with the PostgreSQL 13 beta 2 image.
