Would also like to merge this PR this weekend. - DeeDeeG |

Also merging this today. |
We do all the setup/build steps inside a Docker container, so we don't need ruby tools outside of Docker (on the Travis CI virtual machine instances). Should save about 20 seconds of Travis CI build time. -- Inspired by @btyy77c who did this first at their dockerAlpine branch: - btyy77c@393cf46 Documentation at Travis re: minimal/generic images: - https://docs.travis-ci.com/user/languages/minimal-and-generic/
This (the Alpine Linux-based postgresql image) is a smaller image than the debian-based postgresql image, so it should be marginally faster to download. Seems like a good idea in general, to speed up build times (even outside of Travis CI). Also should save some disk space for developers. -- Inspired by the general concept of @btyy77c's dockerAlpine branch: - https://github.com/btyy77c/refugerestrooms/commits/dockerAlpine Docker Hub documentation on the alpine vs debian postgres images: - https://hub.docker.com/_/postgres#image-variants
