Run CI on forks #2146
Description
In order to make contributions easier, it would be fantastic if we had a clean CI that people can run on their forks. The current workflows are specific to the main repository and fail when run on a fork.
We are currently adding a workflow in #2134 that would run on push on any branch, enabling people to use CI for developments on their own forks, which is great.
So I am happy if we
- Merge Prune CI matrix #2134 to get a CI workflow that people can run on their forks
- Add something like
if: ${{ !github.event.repository.fork }}to workflows that rely on secrets / HPC resources and can't run on forks
This is a crucial step for the Heat hackathon that will be organized as part of HeatHub such that people use their own GitHub CI resources during development on their own forks and do not exhaust the resources of the main repository. Gotta love forks.
