# _chart-releaser_ Action
|
||
|
||
A GitHub action to turn a GitHub project into a self-hosted Helm chart repo, using [helm/chart-releaser](https://github.com/helm/chart-releaser) CLI tool.
|
||
|
||
## Usage
|
||
|
||
### Pre-requisites
|
||
|
||
1. A GitHub repo containing a directory with your Helm charts (default is a folder named `/charts`, if you want to
|
||
maintain your charts in a different directory, you must include a `charts_dir` input in the workflow).
|
||
1. A GitHub branch called `gh-pages` to store the published charts. See `charts_repo_url` for alternatives.
|
||
1. In your repo, go to Settings/Pages. Change the `Source` `Branch` to `gh-pages`.
|
||
1. Create a workflow `.yml` file in your `.github/workflows` directory. An [example workflow](#example-workflow) is available below.
|
||
For more information, reference the GitHub Help Documentation for [Creating a workflow file](https://help.github.com/en/articles/configuring-a-workflow#creating-a-workflow-file)
|
||
|
||
### Inputs
|
||
|
||
- `version`: The chart-releaser version to use (default: v1.4.1)
|
||
- `config`: Optional config file for chart-releaser. For more information on the config file, see the [documentation](https://github.com/helm/chart-releaser#config-file)
|
||
- `charts_dir`: The charts directory
|
||
- `charts_repo_url`: The GitHub Pages URL to the charts repo (default: `https://<owner>.github.io/<project>`)
|
||
- `skip_packaging`: This option, when populated, will skip the packaging step. This allows you to do more advanced packaging of your charts (for example, with the `helm package` command) before this action runs. This action will only handle the indexing and publishing steps.
|
||
- `mark_as_latest`: When you set this to `false`, it will mark the created GitHub release not as 'latest'.
|
||
|
||
### Environment variables
|
||
|
||
- `CR_TOKEN` (required): The GitHub token of this repository (`${{ secrets.GITHUB_TOKEN }}`)
|
||
|
||
For more information on environment variables, see the [documentation](https://github.com/helm/chart-releaser#environment-variables).
|
||
|
||
### Example Workflow
|
||
|
||
Create a workflow (eg: `.github/workflows/release.yml`):
|
||
|
||
```yaml
|
||
name: Release Charts
|
||
|
||
on:
|
||
push:
|
||
branches:
|
||
- main
|
||
|
||
jobs:
|
||
release:
|
||
# depending on default permission settings for your org (contents being read-only or read-write for workloads), you will have to add permissions
|
||
# see: https://docs.github.com/en/actions/security-guides/automatic-token-authentication#modifying-the-permissions-for-the-github_token
|
||
permissions:
|
||
contents: write
|
||
runs-on: ubuntu-latest
|
||
steps:
|
||
- name: Checkout
|
||
uses: actions/checkout@v3
|
||
with:
|
||
fetch-depth: 0
|
||
|
||
- name: Configure Git
|
||
run: |
|
||
git config user.name "$GITHUB_ACTOR"
|
||
git config user.email "$GITHUB_ACTOR@users.noreply.github.com"
|
||
|
||
- name: Install Helm
|
||
uses: azure/setup-helm@v3
|
||
|
||
- name: Run chart-releaser
|
||
uses: helm/chart-releaser-action@v1.5.0
|
||
env:
|
||
CR_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
|
||
```
|
||
|
||
This uses [@helm/chart-releaser-action](https://www.github.com/helm/chart-releaser-action) to turn your GitHub project into a self-hosted Helm chart repo.
|
||
It does this – during every push to `main` – by checking each chart in your project, and whenever there's a new chart version, creates a corresponding [GitHub release](https://help.github.com/en/github/administering-a-repository/about-releases) named for the chart version, adds Helm chart artifacts to the release, and creates or updates an `index.yaml` file with metadata about those releases, which is then hosted on GitHub Pages. You do not need an `index.yaml` file in `main` at all because it is managed in the `gh-pages` branch.
|
||
|
||
#### Example using custom config
|
||
|
||
`workflow.yml`:
|
||
|
||
```yaml
|
||
- name: Run chart-releaser
|
||
uses: helm/chart-releaser-action@v1.5.0
|
||
with:
|
||
charts_dir: charts
|
||
config: cr.yaml
|
||
charts_repo_url: xxxxxx
|
||
env:
|
||
CR_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
|
||
```
|
||
|
||
`cr.yaml`:
|
||
|
||
```yaml
|
||
owner: myaccount
|
||
git-base-url: https://api.github.com/
|
||
```
|
||
|
||
For options see [config-file](https://github.com/helm/chart-releaser#config-file).
