Go mux CI/CD sample (Github actions + Docker + Helm + ArgoCD)

Overview

This repository contains a GoLang web server service implemented using the mux router. The project is containerized using Docker, and the deployment is managed using Kubernetes and Helm. Additionally, GitHub Actions are set up for continuous integration, including building the Docker image, version bumping, and publishing to Docker Hub. The application can be easily deployed and managed using Helm charts and imported into Argo CD for continuous delivery.

Project Structure

• appversion: File containing the application version.
• main.go:  main application server code.
• Dockerfile: Dockerfile for building the application image.
• docker-compose.yaml: Docker Compose file for local development.
• charts: Helm chart folder for deployment.
  • values.yaml: Helm chart values file with an image tag and other configuration.
• Kubernetes: Kubernetes deployment files.
  • deployment.yaml: Deployment file for Kubernetes.
  • service.yaml: Service file with NodePort configuration.
• argocd: Argo CD folder.
  • application.yaml: Argo CD application file for importing the application.

Usage

Local Development

To run the application locally using Docker Compose:

docker-compose up
 

Building Docker Image

helm install/upgrade <release-name> charts/

Deployment using Kubernetes

Apply the Kubernetes deployment and service files:

kubectl apply -f kubernetes/deployment.yaml
kubectl apply -f kubernetes/service.yaml

Argo CD Integration

Import the application into Argo CD using the provided argocd/application.yaml file.

Configuration

Application Version

The application version is stored in the appversion file. It is automatically bumped during the GitHub Actions pipeline.

Helm Values

Configure the Helm chart using the charts/values.yaml file. Adjust image details, replicas, and other settings as needed.

Kubernetes Configuration

Modify the Kubernetes deployment and service files in the kubernetes/ folder to customize the deployment.

Argo CD Application

Update the Argo CD application file (argocd/application.yaml) with the appropriate details for your deployment.
