Skaffold Github Action

Code in src is autogenerated as build outcome from @hiberbee/actions repository, which combines various DevOps Github Actions. If you would like to contribute, create PR in that repository.

Skaffold is a command line tool that facilitates continuous development for Kubernetes applications. You can iterate on your application source code locally then deploy to local or remote Kubernetes clusters. Skaffold handles the workflow for building, pushing and deploying your application. It also provides building blocks and describe customizations for a CI/CD pipeline.

This action allows you to execute skaffold commands as Github Action. Repository is self-testable, so you can refer to Skaffold manifest, Container Structure tests and Github workflow

Example

Build Docker images

jobs:
  pipeline:
    name: Skaffold Docker build
    runs-on: ubuntu-20.04
    steps:
      - name: Build Docker images
        uses: hiberbee/[email protected]
        with:
          command: build
          repository: ghcr.io/hiberbee/docker
          image: nodejs
          tag: ${{ github.sha }}

See more complex example with build, test & deployment simple Helm chart from Dockerfile to local K8S mini cluster.

name: Skaffold
on:
  push:
    paths:
      - src/**
      - .github/workflows/ci.yml
      - action.yml
jobs:
  pipeline:
    name: Skaffold Pipeline
    runs-on: ubuntu-20.04
    steps:
      - name: Checkout sources
        uses: actions/checkout@v3

      - name: Setup Minikube

      - name: Login to Docker Hub
        uses: docker/login-action@v1
        with:
          registry: ${{ secrets.DOCKER_REGISTRY }}
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}

      - name: Run Skaffold pipeline as action
        uses: hiberbee/[email protected]
        with:
          command: run
          repository: ghcr.io/${{ github.repository }}

      - name: Get Helm releases
        run: helm list

CLI usage

You can use that action just to set up Skaffold and then perform actions manually. Here is code sample:
