It’s mind-bogglingly convenient, especially compared to the before times. Consider donating to them if you can.

No one’s mentioned Forgejo yet? Solid git and artifact repository.

+1 for the Seiko 5s. Love me a SNZG07J1

There’s lots of ways to skin this particular cat. My current approach is low powered Synology (j series?) for mass storage, then 1 litre PC’s running proxmox for my compute power using their NVME for storage, all backed up to the Synology.

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.
