High-Level Architecture Diagram for Local GitLab Server with Jenkins

Components Involved:

1. Local Server
   • Runs Jenkins
   • Clones repositories from GitLab
   • Hosts and runs applications
2. Jenkins (CI/CD Tool)
   • Automates repository cloning
   • Builds and runs applications
   • Uses GitLab Webhooks for automated deployment
3. GitLab Repository
   • Stores project code
   • Provides version control
   • Triggers Jenkins pipeline upon code changes (if configured)
4. Office Network
   • Office staff access the apps hosted on the local server
   • Server is reachable via static local IP (e.g., 192.168.1.100)

Flow Diagram Explanation

1. Developer Pushes Code to GitLab Repo
   • Developer commits and pushes code to the GitLab repository
2. Jenkins Pulls Latest Code
   • Jenkins is triggered (manually or via GitLab webhook)
   • It clones or pulls the latest code from GitLab
3. Jenkins Builds and Deploys the Application
   • Runs necessary scripts to start applications
   • Uses Docker (if required) to manage containers
4. Office Staff Access the Applications
   • The application runs on the local server
   • Staff access via a browser (http://192.168.1.100:PORT)

Additional Enhancements

• Use Nginx or Apache for reverse proxy and load balancing.
• Secure the local server using a firewall and authentication.
• Automate deployments with Jenkins pipelines and GitLab triggers.
• Store logs for monitoring using ELK Stack or Prometheus + Grafana.
