GH pages repositories can only serve content to a single subdomain.

This repository enables the RSE website RSE-Sheffield/RSE-Sheffield.github.io to be served at both rse.shef.ac.uk and rse.sheffield.ac.uk.

The CI workflow .github/workflows/mirror.yaml clones RSE-Sheffield/RSE-Sheffield.github.io, builds the gh-pages gem and and deploys the website to github pages, in this case pointed at rse.sheffield.ac.uk, while the website repository deploys to rse.shef.ac.uk.

Deployment is triggered by a workflow_dispatch event from the publish.yaml workflow in RSE-Sheffield/RSE-Sheffield.github.io, when a valid PAT exists. It can also be triggered by pushes to master on this repository, or by an authorised user manually triggering the workflow via a workflow_dispatch.

The following settings must be set on the repository

• Enable Github pages, with GitHub Actions as the source.
• Set the custom domain to rse.sheffield.ac.uk
• Wait up to 24 hours, then enable Enforce HTTPS
