Docker commit and get rid of old images

I have to keep committing on running docker containers, with timestamp tags. This creates new docker images.

Now, I want to get rid of old images from which the container was spawned in the beginning, cause it wont be used anymore.

I can write code to do this using a lot of logic and regex but, is there any other graceful way to do this?

How does the docker community do this?

Don't forget to do this only after committing the container. If you delete the original image of a container, then docker will throw an error (no such file or directory) when you try to commit it

You can clean up unused Docker images at any time using this command:

docker image prune -a

This will remove all Docker images without at least one container associated to them. This includes dangling images:

-a Remove all unused images, not just dangling ones
