Krane container

This container is intended to be used in GitHub Actions to deploy your code with Smartly.io Krane deploy action to Kubernetes cluster.

Prerequisites

You'll need

• an image published to some container registry (DockerHub, AWS ECR, anything)
• a running publicly accessible kubernetes cluster
• your deployment templates defined in the same repository you deploy from

How to use this

Here is an example workflow.

name: CI

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  test:
    # Some test actinos
  publish:
    # Publish your image
    runs-on: ubuntu-latest
    steps:
      -
        name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v1
      -
        name: Login to DockerHub
        uses: docker/login-action@v1
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}
      -
        name: Build and push
        id: docker_build
        uses: docker/build-push-action@v2
        with:
          push: true
          tags: user/app:latest

  deploy:
    name: Deploy with Krane
    needs: publish
    runs-on: ubuntu-latest
    container: ghcr.io/kblcuk/krane-container:1.0.0 # This is important line! We want to run this job in container
    steps:
      - uses: actions/checkout@v2
      # Running with renderOnly:true does not require login
      - name: Authenticate to kube cluster
        env:
          KUBERNETES_AUTH_TOKEN: ${{ secrets.KUBERNETES_AUTH_TOKEN }}
