GitHub Actions Kubernetes Toolkit

This action started as a fork of steebchen/kubectl, but the solution is now very different. If you just need to directly run a single kubernetes command, simply use that action.

If instead, you need to run multiple kubectl commands, or helm, this action installs these tools and configures them, so that they can be used throughout the remaining steps in your job.

This action provides kubectl and helm for GitHub Actions.

As with the upstream inspiration for this project, please ⭐ it if you do end up using it!

Usage

.github/workflows/push.yml

on: push
name: deploy
jobs:
  deploy:
    name: deploy to cluster
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: deploy to cluster
      uses: bwvolleyball/k8s-toolkit@v1.0.0
      with: # defaults to latest kubectl & helm binary versions
        config: ${{ secrets.KUBE_CONFIG_DATA }}
        kubectl_version: v1.21.5
        helm_version: v3.7.0
    # After it's been configured, you can now freely use kubectl & helm commands the rest of the job.
    # This could also be used for multi-cluster deployment, as long as your provided kube config has all required clusters.
    - name: Check kubectl version
      run: kubectl version
    - name: Check helm version
      run: helm version
    - name: Update Deployment
      run: set image --record deployment/my-app container=${{ github.repository }}:${{ github.sha }}
    - name: Helm Deployment
      run: helm upgrade my-release my/chart --namespace namespace
    - name: verify deployment
      run: helm test my-release --namespace namespace

Arguments

config – required: A base64-encoded kubeconfig file with credentials for Kubernetes to access the cluster. You can get it by running the following command:

cat $HOME/.kube/config | base64

Note: Do not use kubectl config view as this will hide the certificate-authority-data.

kubectl_version: The kubectl version with a 'v' prefix, e.g. v1.21.0. It defaults to the latest kubectl binary version available.

helm_version: The helm version with a 'v' prefix, e.g. v3.7.0. It defaults to the latest helm binary version available. Since this is read from the GitHub releases, it could easily be a pre-release binary. You are strongly encouraged to explicitly set the version for this.
