This documentation outlines the CI/CD deployment strategy for the benhall/golang-demo project. While a full CI/CD pipeline is not yet set up, this guide provides a step-by-step framework on how one could be implemented using best practices for the Go application.

Current Status

As of the latest update, the CI/CD setup is not yet established. However, below are recommended steps to implement a CI/CD pipeline for this Golang project.

Suggested Next Steps

  1. Test Automation: Implement unit and integration tests using Go’s testing framework. Ensure all tests are passing before deployment.

  2. CI Tool Selection: Choose a CI/CD tool such as GitHub Actions, GitLab CI, Jenkins, or CircleCI.

  3. Dockerization: Since the project already includes a Dockerfile, ensure that it adheres to Docker best practices.

  4. Deployment Configuration: Specify deployment configurations (e.g., Kubernetes manifests, cloud provider configuration), depending on where the application will be hosted.

  5. Environment Variables: Set up configurations for various environments, ensuring security and separation of concerns.

CI/CD Pipeline Implementation Example

The following example details how one might set up CI/CD in a GitHub Actions workflow for the Go application using the existing Dockerfile.

Example GitHub Actions Workflow

Create a .github/workflows/build-and-deploy.yml file:

name: CI/CD Pipeline

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: '1.21'

      - name: Run tests
        run: go test ./...

      - name: Build Docker image
        run: |
          docker build -t myapp:latest .

      - name: Log in to Docker Hub
        run: echo "${{ secrets.DOCKER_HUB_PASSWORD }}" | docker login -u "${{ secrets.DOCKER_HUB_USERNAME }}" --password-stdin

      - name: Push Docker image
        run: |
          docker tag myapp:latest your-dockerhub-username/myapp:latest
          docker push your-dockerhub-username/myapp:latest

Explanation of Workflow Steps

  1. Checkout Code: The workflow starts by checking out the code using the checkout action, ensuring the latest changes are built.

  2. Set up Go: The setup-go action is used to configure the Go environment for building the application. The version is set to 1.21, matching the base image in the Dockerfile.

  3. Run Tests: All tests within the application are executed using go test, helping to ensure code quality.

  4. Build Docker Image: A Docker image is built using the Dockerfile located in the root of the repository.

  5. Log in to Docker Hub: The workflow logs into Docker Hub using credentials stored as secrets to maintain security.

  6. Push Docker Image: Finally, the newly built Docker image is tagged and pushed to the Docker Hub repository for further deployment configuration.

Conclusion

By integrating testing, Docker, and a CI/CD platform such as GitHub Actions, a robust pipeline can be established, promoting an efficient development workflow and facilitating continuous integration and deployment for the benhall/golang-demo project.

This lays the groundwork for effective CI/CD deployment. Once the aforementioned steps are implemented, the project can achieve a consistent release process in a fully automated manner.
