## Live Branch
This branch contains generated assets that have been officially released on rke2-charts.rancher.io.
The following directory structure is expected:
```text
assets/
<package>/
<chart>-<packageVersion>.tgz
...
charts/
<package>
<chart>
<packageVersion>
# Unarchived Helm chart
```
### Configuration
This repository branch contains a `configuration.yaml` file that is used to specify how it interacts with other repository branches.
#### Sync
This branch syncs with the generated assets from the following branches:
- main-source at https://github.com/rancher/rke2-charts.git (only latest assets)
To release a new version of a chart, please open the relevant PRs to one of these branches.
Merging should trigger a sync workflow on pushing to these branches.
### Cutting a Release
In the Live branch, cutting a release requires you to run the `make sync` command.
This command will automatically get the latest charts / resources merged into the the branches you sync with (as indicated in this branch's `configuration.yaml`) and will fail if any of those branches try to modify already released assets.
If the `make sync` command fails, you might have to manually make changes to the contents of the Staging Branch to resolve any issues.
Once you successfully run the `make sync` command, the logs outputted will itemize the releaseCandidateVersions picked out from the Staging branch and make exactly two changes:
1. It will update the `Chart.yaml`'s version for each chart to drop the `-rcXX` from it
2. It will update the `Chart.yaml`'s annotations for each chart to drop the `-rcXX` from it only for some special annotations (note: currently, the only special annotation we track is `catalog.cattle.io/auto-install`).
Once you successfully run the `make release` command, ensure the following is true:
- The `assets/` and `charts/` directories each only have a single file contained within them: `README.md`
- The `released/assets/` directory has a .tgz file for each releaseCandidateVersion of a Chart that was created during this release.
- The `index.yaml` and `released/assets/index.yaml` both are identical and the `index.yaml`'s diff shows only two types of changes: a timestamp update or a modification of an existing URL from `assets/*` to `released/assets/*`.
No other changes are expected.
