CI/CD Pipeline for Kubernetes Deployment and Testing of 5G Core

Overview

This project demonstrates an automated CI/CD pipeline for deploying and testing a 5G Core network. It integrates Open5GS for the core network, UERANSIM for UE simulation, Docker for containerization, Kubernetes for orchestration, and GitHub Actions for automation.

---

Technologies Used

• Open5GS (5G Core Network)
• UERANSIM (UE and gNB Simulation)
• Docker
• Kubernetes (Minikube)
• GitHub Actions (CI/CD Pipeline)

---

Installation Summary

The setup involves installing Docker, Kubernetes (Minikube), Open5GS, and UERANSIM. After installation, the system is configured so that Docker images can be used inside Kubernetes.

Deployment Process

1. Build the Docker image for Open5GS
2. Deploy the application to Kubernetes
3. Verify deployment status
4. Expose services for communication

---

Testing Process

• A UE (User Equipment) connects to the 5G Core
• Registration and session establishment logs are checked
• Based on logs, the system outputs PASS or FAIL

---

🔁 CI/CD Pipeline

The CI/CD pipeline is triggered automatically on every push to the repository. It performs:

• Code checkout
• Docker image build
• Kubernetes deployment
• Execution of test scripts
• Validation of results

---

Multiple UE Testing

• Multiple UEs are launched simultaneously
• Each UE attempts to connect to the 5G Core
• Logs are analyzed to verify successful connections
• The system reports PASS if all UEs connect successfully
