Overview

warning

This content only apply for lab purpose. If you want apply it into production, you need more things to do (ArgoCD, Gitlab CI/CD, etc.)

Target: This guideline take you from zero to build a complete DevOps system on Google Cloud Platform (GCP), including Technitium - DNS server, NPM - Reverse Proxy, Gitlab, Jenkins, Docker, and finally, an pipeline deploy to Docker automatically.

Final Result: You will have the system which just git push and everything relate (build, check, approval, deploy) will run automatically

Virtual Machine's architecture​

Let's take a look into VM's architecture first VM's architecture The containers are organized into:

  • NGINX container (NPM):

    • Port expose: 80 (HTTP)
    • Acts as a reverse proxy, forwarding traffic to:
      • Jenkins on port 8080,443
      • Gitlab on port 80,443

  • Technitium container (DNS):

    • Port expose: 5380
    • Acts as a local DNS

  • Jenkins container:

    • Port expose: 8080
    • Connected directly to the VM's Docker daemon

  • Gitlab container:

    • Port expose: 80 (UI), 22 (ssh), 5050 (container registry)
