Docker builds are crazy wasteful in terms of bandwidth and compute. Right now I'm struggling with a project that builds ITK on demand every heckin time. I'm working through how to best integrate apt-cacher-ng, sccache, and a pip cacher. It costs me nothing to hit apt or pypi, but like, somebody is paying that bill. A little perspective goes a long way. I wonder if I could do something to just proxy all requests and cache those on a whitelist and stick it on my CI network.
