krew-release-bot is a bot that automates the update of plugin manifests in krew-index when a new version of your kubectl plugin is released. If a release is marked as a 'prerelease' in github, it will not be released to the krew index.

To trigger krew-release-bot you can use a github-action which sends the event to the bot.

Basic Setup

Make sure you have enabled github actions for your repo
Add a .krew.yaml template file at the root of your repo. Refer to kubectl-evict-pod repo for an example.
- you could use https://rajatjindal.com/tools/krew-release-bot-helper/ for generating template for your plugin
To setup the action, add the following snippet after the step that publishes the new release and assets:
```
- name: Update new version in krew-index
  uses: rajatjindal/krew-release-bot@v0.0.46
```
Check out the goreleaser example below for details.

Example when using go-releaser

<your-git-root>/.github/workflows/release.yml

name: release
on:
  push:
    tags:
      - "v*.*.*"
jobs:
  goreleaser:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@master
      - name: Setup Go
        uses: actions/setup-go@v4
        with:
          go-version: '1.20'
      - name: GoReleaser
        uses: goreleaser/goreleaser-action@v1
        with:
          version: latest
          args: release --rm-dist
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      - name: Update new version in krew-index
        uses: rajatjindal/krew-release-bot@v0.0.46

** You can also customize the release assets names, platforms for which build is done using .goreleaser.yml file in root of your git repo.

Testing the template file

You can test the template file rendering before check-in to the repo by running following command

$ docker run -v /path/to/your/template-file.yaml:/tmp/template-file.yaml ghcr.io/rajatjindal/krew-release-bot:v0.0.46 \
  krew-release-bot template --tag <tag-name> --template-file /tmp/template-file.yaml

Inputs for the action

Key	Default Value	Description
workdir	`env.GITHUB_WORKSPACE`	Overrides the GitHub workspace directory path
krew_template_file	`.krew.yaml`	The path to template file relative to $workdir. e.g. templates/misc/plugin-name.yaml

Limitations of krew-release-bot

only works for repos hosted on github right now
The first version of plugin has to be submitted manually, by plugin author, to the krew-index repo

Kubernetes CLA

krew-release-bot is just a service to open PR on your behalf to release a new version of the krew-plugin. Your CLA agreement (that you did when submitting the new plugin to krew-index) is still applicable on these PR's.
