Old images not deleted in docker mode when a new one is pulled

[paraschopra]

Question: quite frequently, cco pulls up a new docker image (which takes time because it is many GBs). Why does it do that?

Also once it pulls an image, I see 3 images. 2 are latest and 1 old. I have to delete the old one manually. But also I wonder why are there two images (each ~6gb), instead of one.

Hi,

The images are rebuilt regularly in CI to keep packages fresh, but cco shouldn't pull new images unless you're calling it with --pull or otherwise triggering a re-download. During normal startup it just (re-)uses cco:latest. Can you say more about when you're seeing that happen?

As for the multiple copies, good catch, it wasn't cleaning up old ones at all. WIth #61 it'll now ask you if you'd like to clean them up when it sees them, or you can pass --clean-old-images to always have cco clean old ones.

I run cco in a docker and it sometimes pulls up new image automatically (without invoking pull flag).

Ok, will investigate
