How to delete old images??

[DerTom]

Hi!

I'm fighting with a container and would like to delete every downloaded image while pulling this container. I would like to get rid of the message (already exists)! I tried 'docker image prune -a' and 'docker image prune -a -f' but this did not do it.

Adding options '--no-cache' or '--pull' did not work also.

How do I delete this old images?
At which location are this already downloaded images stored?

Kind regards,

 

I would like to have every image with a new pull.

They are stored inside the docker.img file.

 

You can delete and recreate it empty, and all layers will be downloaded fresh. If you have any custom networks, make sure you recreate those before you pull any containers that reference them.

I don't think that'll help, the error is about an invalid character in one of the new layers being extracted.

 

To explain the workings, many layers are shared between containers, to remove them you'd have to remove every container that uses them. I.e. you'd want to start by removing all LSIO containers since they're specifically designed to share layers.

Thank you for your help!

The container has been updated and the error is gone!
