Cloud Platform Helm repository to store the internal helm charts.
The main advantage is directly related to maintainability: we don’t need to keep an eye ay service, just in source code.
Adding a helm repository is as easy as:
$ helm repo add cloud-platform https://ministryofjustice.github.io/cloud-platform-helm-charts
Keep in mind two things:
1) Source code of helm charts are inside the main branch, 2) Artifacts inside gh-pages branch which are the ones publicly distributed and available in url https://ministryofjustice.github.io/cloud-platform-helm-charts
If you want to include a new helm chart or amend existing helm chart to create new artifacts(with latest chart version) and publish the artifacts follow the below steps
Build the artifacts tarballs(tgz) using the command:
helm package <chart-name>
Regenerate index.yaml
helm repo index --url https://ministryofjustice.github.io/cloud-platform-helm-charts/ --merge index.yaml .
Once the PR is merged to main branch, the github action sync-branches.yml will push the artifacts into gh-pages branch. The regenerated index (index.html) can then used to upgrade the chart by doing helm repo update
