CI/CD and Automation

Overview

This document outlines the CI/CD and automation processes for the apko project. These processes leverage GitHub Actions to automate builds, tests, and deployments.

CI/CD Workflow

The CI/CD workflow for apko is primarily driven by GitHub Actions, which are defined in the .github/workflows directory. Each workflow performs a specific task, such as building, testing, or deploying the project.

Workflow Examples

Here are some examples of workflows defined in the workflows directory:

• build.yml: This workflow builds the project and runs unit tests. The workflow uses the ubuntu-latest runner and utilizes the actions/checkout@v3 action to checkout the code and setup-go@v3 action to set up the Go environment.
• release.yml: This workflow triggers on releases and publishes artifacts to GitHub Releases. It utilizes the actions/upload-artifact@v3 action to upload the built artifact.
• publish-docker.yml: This workflow builds and publishes Docker images to Docker Hub. It utilizes the docker/build-push-action@v3 action to build and push the image.

Code Examples

Here are some code examples from the .github/workflows directory:

# .github/workflows/build.yml
          name: Build
          on:
            push:
              branches:
                - master
            pull_request:
              branches:
                - master
          jobs:
            build:
              runs-on: ubuntu-latest
              steps:
              - uses: actions/checkout@v3
              - uses: actions/setup-go@v3
                with:
                  go-version: 1.18
              - name: Build
                run: go build -v ./...
              - name: Test
                run: go test -v ./...
          

# .github/workflows/release.yml
          name: Release
          on:
            release:
              types: [published]
          jobs:
            release:
              runs-on: ubuntu-latest
              steps:
              - uses: actions/checkout@v3
              - uses: actions/setup-go@v3
                with:
                  go-version: 1.18
              - name: Build
                run: go build -v ./...
              - name: Upload artifacts
                uses: actions/upload-artifact@v3
                with:
                  name: apko
                  path: apko
          

# .github/workflows/publish-docker.yml
          name: Publish Docker Image
          on:
            push:
              branches:
                - master
          jobs:
            publish:
              runs-on: ubuntu-latest
              steps:
              - uses: actions/checkout@v3
              - uses: docker/build-push-action@v3
                with:
                  context: .
                  push: true
                  tags: ${{ runner.os }}-latest
          

Best Practices

• Maintain Code Quality: The CI/CD pipeline includes automated code quality checks, such as linters and static analysis tools, to ensure high-quality code.
• Test Coverage: Unit tests and integration tests are essential for ensuring code functionality and stability. The CI/CD pipeline includes coverage reports to track progress and identify areas for improvement.
• Deployment Automation: The CI/CD pipeline streamlines the deployment process, automating the steps involved in deploying new versions of the software.
