| name: GitHub Codespaces image build | |
| # Run only on master branch. We could also build on branch but this seems like | |
| # an optimization that can be done as and when desired. The main use case we're | |
| # handling is creating and working off a branch from master, so it doesn't seem | |
| # like an immediate requirement to have branches as well. | |
| # | |
| # NOTE: the job is setup to also push branch images as well, and using branch | |
| # and master as caching, so if we want to add the optimisation for branches we | |
| # can just remove the master branch restriction. | |
