separate runas concerns

flavorjones commented 3 years ago

This addresses the concerns raised in #41

I'd like to make the rake-compiler-dock OCI images easier to use in CI systems by extracting the "build environment" setup out of build/runas and making it part of the non-interactive shell initialization.

This PR does a few things:

generalizes the test_environment_variables.rb tests to run with the rake-compiler-dock wrapper and without it (as a bare docker command)
introduces build/rcd-env.sh which contains the parts of runas unrelated to user/group/filesystem config
ensures rcd-env.sh is loaded by all shells
adds a section to the README with an example of how to use the images in a CI pipeline

The net result is that CI systems won't need to set environment variables in order to use the RCD images for gem building.

Sorry @flavorjones for waiting so long! I had to cut down my online activities lately. I plan to use my vacation next 1.5 weeks for all ruby-3.1 related tasks.

Thank you @flavorjones for the changes! I'll release rake-compiler-dock-1.2.0 today or tomorrow. See #58.
