BubuStack Helm Charts

This repository contains the Helm charts published for the BubuStack projects:

• bobrapet – the workflow operator
• bobravoz-grpc – the transport hub
• bubuilder - BubuStack UI

Charts are stored under charts/<name> and should not be edited manually. They are generated from the corresponding operator repositories through the release workflows and arrive here via automated pull requests.

Release pipeline

1. A new release is cut in bobrapet, bobravoz-grpc, or bubuilder via Release Please.
2. The sync-helm-chart job stamps the release version into Chart.yaml and values.yaml, runs helmify, and opens a pull request in this repository.
3. When the pull request is merged into main, the Publish Helm Charts workflow packages the charts, updates the GitHub Pages index via helm/chart-releaser, and pushes OCI artifacts to ghcr.io/bubustack/charts.

Local development

• Keep long-lived defaults (e.g., tuned values.yaml) inside the source repositories under hack/charts/<name>.
• Let automation regenerate templates — only review and merge the resulting PRs here.
• Chart versions and appVersion are stamped automatically from the operator release tag. No manual version bumps needed.
