Thanks for all the great replies!
Retag and push to a local registry. Lots of options out there for setting one up.
Honestly, you already have the image locally if you’ve pulled it. You don’t really need to run a registry unless you’re dead set on it. You can also flatten and export containers for backup if you really want.
Two good points here OP. Type
docker image ls
to see all the images you currently have locally - you’ll possibly be surprised how many. All the ones tagged<none>
are old versions.If you’re already using github, it includes an package repository you could push retagged images to, or for more self-hosty, a local instance of Forgejo would be a good option.
Sorry for the link dump - I just glanced over the content and it seems like this might help you:

Just use a sonatype nexus 3 image and proxy docker hub, etc. Then you pull images through it.
We run this at work so we have forever copies of image tags and to reduce dockerhub rate limit issues. Works well even for a large dev team.
At my job, we run goharbor.io and use its Replications feature to do just that.
I mean you have the current image cached on the local server when you use it.
