Gitlab CI example

[o1lo01ol1o]

The CI example here uses the nixos/nix:latest tag: https://docs.cachix.org/continuous-integration-setup/gitlab.html. This docker image -- and numerous others that I've tried -- cabal2nix mysteriously pulls in pyopenssl and fails to build the test suite:

===Flaky Test Report===
test_gmtime_adj_notBefore passed 1 out of the required 1 times. Success!
test_gmtime_adj_notAfter passed 1 out of the required 1 times. Success!
===End Flaky Test Report===

This is the same error as : https://github.com/obsidiansystems/obelisk/issues/837

Locally, it seems like any recent nixpkgs commit on 20.09 or unstable builds without issue; I'm not sure why nix:latest does not.

I'd suggest setting NIX_PATH= with a nixpkgs commit that makes it work.

Gitlab instructions are mostly rewritten, did you manage to get it to work?

[o1lo01ol1o]

Yes, I did thanks. Iirc, there were some upstream issues in the dependencies in question that dragged things out a bit more.

Feel free to close.
