Ah interesting, yeah the whole container build -> CI build has been a long-standing paint point for me across Github, GitLab, and even Jenkins. I will investigate what depot.dev is doing.... cause yeah, proper and intelligent on-demand rebuilding of based containers could be a game changer.

One of the founders of Depot here. Always feel free to ping me directly (email in my bio) if you ever want to chat more about container builds in general.

For sure! I've always felt like a bit of a loner in that the assumption in most of these platforms is that your build starts with either something barebones (just apt) or maybe your platform only (python3:latest).

However, I've typically dealt with builds that have a very heavy dependency load (10-20GB) where it isn't desirable to install everything every time— I'd rather have an intermediate "deps" container that the build can start from. But I don't want to have to manually lifecycle that container; if I have a manifest of what's in my apt repo vs the current container, it should just know automatically when a container rebuild is required.
