Many thanks. This builds correctly AFAIK, and I believe that build failure is due to you working in a fork??

We enforce trailing spaces in our files using pre-commit, which can be added by running pre-commit install if you have it installed.

Finally, we also use changelog files (see changelog/README.md)

[lewisjared]

LGTM, although I haven't tried pulling the container locally. Let me know if this is ready to go or if you wanted to add more to this PR

@lewisjared I think this is mostly good to go for a first pass, except I don't see the image showing up at https://github.com/orgs/Climate-REF/packages even though it appears to have pushed successfully. Could the package be marked as private?

[lewisjared]

Yes it was private, but I've changed it to now be public
