Welcome to the 3-Tier Application CI/CD Pipeline project! This project automates the process of building, testing, and deploying a 3-tier application using Jenkins, Docker, and Kubernetes. Developers commit code to Git, triggering Jenkins to build a Docker image, push it to Docker Hub, and deploy the application to a Kubernetes cluster. The system includes monitoring and feedback mechanisms to ensure application reliability.
- CI/CD Automation: Fully automated pipeline from code commit to deployment.
- Docker Integration: Builds Docker images for consistent application environments.
- Kubernetes Deployment: Deploys and scales applications across a Kubernetes cluster.
- Monitoring & Feedback: Ensures reliability and uptime with monitoring tools.
Ensure you have the following tools and platforms set up:
- Git
- Jenkins
- Docker
- Docker Hub Account
- Kubernetes Cluster
-
Code Commit Developers commit code to a Git repository.
-
Jenkins Build Trigger Jenkins is configured to monitor the repository. A new commit triggers the pipeline.
-
Docker Image Build Jenkins builds a Docker image for the application and pushes it to Docker Hub.
-
Kubernetes Deployment Jenkins deploys the Docker image to a Kubernetes cluster using
kubectl. -
Monitoring Feedback and monitoring tools provide insights into the application’s performance.
Pulls the latest code from the Git repository.
Creates a Docker image using the Dockerfile.
Pushes the built image to Docker Hub for storage.
Uses kubectl to deploy the Docker image to the Kubernetes cluster.
Ensures the application is running as expected and collects performance data.
