GitOps Documentation - tophomelab.work

Overview

This repository follows a GitOps approach for developing, deploying, and managing a distributed website with APIs.

Project Components

  • Frontend: [React/Next.js/Vue.js]
  • Backend APIs: [Node.js/Go/Python]
  • Infrastructure: Kubernetes (EKS/GKE/AKS)
  • CI/CD: GitHub Actions, ArgoCD, Flux
  • Monitoring & Logging: Prometheus, Grafana, Loki

Git Workflow (git-workflow.md)

  1. Create a Feature Branch:
    git checkout -b feature/new-feature
git push origin feature/new-feature
  2. Merge via Pull Request.
  3. Automated Deployment (CI/CD via GitOps).

API Docs (api-docs.md)

  • OpenAPI/Swagger documentation.
  • Example API request/response format.

2️⃣ Deployment Guide (/docs/deploy/)

GitOps Deployment (gitops-deploy.md)

  • ArgoCD/Flux setup
  • Automatic sync to Kubernetes
  • Helm Charts structure

Rollback Strategy (rollback.md)

git revert <commit-hash>
git push origin main
- Rollback using Helm: 
helm rollback release-name 1

3️⃣ Operations & Support (/docs/support/)

Monitoring (observability.md)

  • Prometheus/Grafana dashboards.
  • Kubernetes logs using Loki.

Troubleshooting (troubleshooting.md)

Issue Solution
Pod CrashLoopBack Check logs: kubectl logs pod-name

Incident Response (incident-response.md)

  1. Identify issue.
  2. Escalate if needed.
  3. Apply rollback/fix.

4️⃣ Architecture (/docs/architecture/)

System Design (architecture-overview.md)

  • High-level architecture diagram using Mermaid.js: 
    graph TD;
User -->|Request| API[Backend API]
API -->|Fetch| Database
API -->|Serve| Frontend
  • Microservices communication diagram.

🚀 Next Steps

  • Automate docs using Docusaurus or MkDocs.
  • Integrate with GitHub Wiki or SharePoint.
  • Keep documentation up-to-date with CI/CD.

Would you like me to refine any part? 😊
