benhall / golang-demo

Overview

The benhall/golang-demo project does not currently have a CI/CD workflow set up. This documentation will outline next steps that can be taken to implement a robust CI/CD pipeline for the project using industry-standard tools and practices.

Implementation Steps

Step 1: Choose a CI/CD Platform

Select a CI/CD tool that fits your project needs. Common choices include:

  • GitHub Actions
  • GitLab CI/CD
  • Travis CI
  • CircleCI

Step 2: Define CI/CD Pipeline

After selecting a CI/CD platform, define the pipeline configuration file. Below is an example using GitHub Actions, which illustrates how to build and push a Docker image to a container registry.

Create a file named .github/workflows/ci-cd.yml in your repository:

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: Build the application
      run: |
        cd /app
        go mod download
        go build -o myapp

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

    - name: Push Docker image
      run: |
        docker tag myapp yourusername/myapp:latest
        echo "${{ secrets.DOCKER_PASSWORD }}" | docker login -u yourusername --password-stdin
        docker push yourusername/myapp:latest

Step 3: Set Up Secrets

Ensure that you set up the necessary secrets in your chosen CI/CD platform. In GitHub Actions, you will need to store your Docker Hub credentials:

  • Navigate to your GitHub repository.
  • Go to Settings > Secrets > Actions.
  • Add secrets for DOCKER_USERNAME and DOCKER_PASSWORD.

Step 4: Build and Deploy

Once your CI/CD pipeline YAML configuration is set up, commit your changes and push them to the main branch. The CI/CD tool will automatically run the defined workflow, building the Docker image and optionally pushing it to your container registry.

Step 5: Monitor and Adjust

After implementing the CI/CD workflow, monitor its execution to ensure that it’s working as intended. Make adjustments as necessary to optimize build times, handle errors, and ensure deployments are successful.

Step 6: Future Enhancements

  • Integrate automated testing to ensure code quality before the build step.
  • Set up notifications for build failures or successes.
  • Use environment variables to manage configuration settings.

Conclusion

Implementing a CI/CD pipeline for the benhall/golang-demo project allows for streamlined development processes and enhances the ability to deliver code changes efficiently. By following the outlined steps, developers can set up a robust CI/CD workflow tailored to the needs of the project.
