How to use

Set up KUBE_CONFIG_DATA secret

Encode your kubeconfig file with base64 encoding.

cat $HOME/.kube/config | base64

Store the encoded string as a secret with name KUBE_CONFIG_DATA, by navigating to your repo -> Settings -> Secrets -> Add a new secret

Config a Github workflow

Create a workflow file .github/workflows/deploy.yaml

on: push
name: deploy
jobs:
  deploy:
    name: deploy to cluster
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: deploy to cluster
      uses: wahyd4/kubectl-helm-action@master
      env:
        KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
      with:
        args: kubectl apply -f manifest.yaml

Or you may want to deploy applications with helm

- name: deploy postgres to cluster
  uses: wahyd4/kubectl-helm-action@master
  env:
    KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
  with:
    args: |
      helm repo add bitnami https://charts.bitnami.com/bitnami
      helm upgrade --install postgres -n data bitnami/postgresql

Switch versions

You can switch to different helm version by using different tags, current the master branch uses helm 3.13

• 3.12 wahyd4/kubectl-helm-action@3.12
• 3.13 wahyd4/kubectl-helm-action@3.13
• 3.14 wahyd4/kubectl-helm-action@3.14
• 3.15 wahyd4/kubectl-helm-action@3.15
