on: push
name: deploy
jobs:
  deploy:
    name: deploy to cluster
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: deploy to cluster
      uses: steebchen/kubectl@v2.0.0
      with: # defaults to latest kubectl binary version
        config: ${{ secrets.KUBE_CONFIG_DATA }}
        command: set image --record deployment/my-app container=${{ github.repository }}:${{ github.sha }}
    - name: verify deployment
      uses: steebchen/kubectl@v2.0.0
      with:
        config: ${{ secrets.KUBE_CONFIG_DATA }}
        version: v1.21.0 # specify kubectl binary version explicitly
        binaries-url: "https://dl.k8s.io/release/v1.21.0/bin/linux/amd64/kubectl" # specify the download url explicitly
        command: rollout status deployment/my-app

Arguments

command – required: The command you want to run, without kubectl, e.g. get pods

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

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

binaries-url: The url to download the binaries from. It defaults to the official release page if empty.

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