With the proposed changes the time required to run `./bin/compose setup` is being reduced from ~18 minutes down to ~7 minutes on my machine. In addition a workaround is applied to reduce the size of the images. == Changes === Speed-Up `bundle install` The time spent withing `bundle install` takes a significant amount time during the `./bin/compose setup`. We could make use of two improvements, which both allows us to utitlize multiple CPU cures: * Make use of the bundle `--jobs` argument * Make use of the lesser known/used `MAKE` environment variable A significant amount of time spent during `bundle install` is actually compiling C-extensions, that's why the usage of the `MAKE` variable will drastically improve performence. === `useradd --no-log-init` Unfortunately there is a nasty bug when running `useradd` for a huge `uid`, which could result in excessive image sizes. See attached links for more information. === BuildKit BuildKit is the default builder toolkit for Docker on Windows and DockerDesktop on Macs. Using BuildKit will greatly improve performance when building docker images. == Links === Speed-Up `bundle install` * [One Weird Trick That Will Speed Up Your Bundle Install](https://build.betterup.com/one-weird-trick-that-will-speed-up-your-bundle-install/) === BuildKit * [Build images with BuildKit](https://docs.docker.com/develop/develop-images/build_enhancements/) * [Faster builds in Docker Compose 1.25.1 thanks to BuildKit Support](https://www.docker.com/blog/faster-builds-in-compose-thanks-to-buildkit-support/) === `useradd --no-log-init` * Best practices for writing Dockerfiles: [User](https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#user) * golang/co: [archive/tar: add support for writing tar containing sparse files](https://github.com/golang/go/issues/13548)
