PUBLIC

The goal of this PR is to separate gh-pages and source code a.k.a charts and re-use the same workflow to publish all charts across G-Research OSS repositories

• master branch (DRAFT - INTERNAL refactor gh pages #107 )
  • place for source code (e.g charts, values..etc)
  • we don't want *.tgz files here
• gh-pages branch (this PR)
  • all public related stuff (e.g index.yaml for the repo, raw chart files...etc)
  • we want only *.tgz files here + github pages content

Prerequirements

• Source for GitHub pages should point togh-pages branch with / for root directory
• Create GitHub App on the organization
• Allow GitHub app permissions over this repo and the ones which will call workflow_dispatch
• Create following secrets on this repo
  • APP_ID
  • GH_APP_PEM
  • INSTALLATION_ID

Here you can find example run for publishing storm charts
Input: publish-storm.yaml on INTERNAL-refactor-master branch (e.g workflow example)
Action: publish-charts.yaml (part of this PR) is triggered with given inputs (e.g workflow-run-inputs.yaml)
Output:

• gh-pages updated with new charts published and index.yaml updated
• raw charts (.tgz files) published to destination path and index.yaml updated
