Github Action to Build Catalog

[anton-seaice]

Is your feature request related to a problem? Please describe.

To build the catalog currently requires manual intervention.

Describe the feature you'd like

When a pull request is created - build a copy of the catalog on Gadi, and make available to the developer/reviewer to fix any issues.

When a new version is tagged - build a copy of the catalog on Gadi and move it to the public copy (initially with an extra step for a human to confirm first?)

This should be possible with github actions.

Describe alternatives you've considered

We could write an instruction for a reviewer on how to build the catalog, or use the access-dev jenkins server or similar.

I agree it would be nice to have a full CD workflow. This has been on my todo list for a long time, but I've been waiting for the Github runners Aidan's team are setting up on Nirin (we definitely don't want to use access-dev as that will not be available very soon). We could instead just ssh from a Github runner.

One difficulty is that the full build takes ~1.5 hours and so we probably don't want to be doing this with every pull request. But we could set things up so that users could trigger a "non-release" build from Github if they wanted to.

Thanks The Nirin solution sounds like it could be the neatest, so lets wait. I think run the full build so we know it all works, and just make sure it goes into scratch and gets cleaned up regularly.

Aidan says they're still testing the Nirin Github runner, but it should be ready in the next week or so

Note @rbeucher made a start on this but I'm not sure how much further he plans to take it? What he's added so far is a github workflow to manually trigger the build job on Gadi. As discussed in this thread, it would be good to have the build happen automatically on releases and PRs, but a little extra logic is required for handling non-release builds (could be as simple as building to tmp). @rbeucher, have you finished what you've been adding or are you planning to do more?
