Can I delete previously pulled qiime2 core in docker?

[Lennon_Lee]

Dear all, I have checked my docker images just now and found that the previously pulled qiime2 core are still stored:

Can I delete the previous images to save space, will it affect my current qiime2 core?
And if I can, may I know how?

Hi @Lennon_Lee,

This digital ocean tutorial is really nice (like most of theirs are):

How To Remove Docker Images, Containers, and Volumes | DigitalOcean

You should be able to use the docker rmi subcommand.

Docker is pretty good about retaining intermediate images when they are shared (which are not usually even presented to you) so you won't affect containers which you aren't specifically removing.

Thank you so much for the help!!!
