I setup a local docker cache using a docker image. The transition to HTTPS everywhere makes caching this sort of thing difficult. One has to install and often manually configure trusted certificates on every client to maximize the cache. APK and APT caches often come hand-in-hand for this sort of thing as the logical next step is to add some OS packages to the pulled image. This also benefits from local caching and also means frustrating cache setup, certificate setup, etc. To maximize local caching there's a lot of manual work to setup a house-of-cards series of proxies that only work on the network. Setting it up on a laptop then traveling means everything breaks in not-so-obvious ways when you leave the network.
