CI/CD pipeline using Jenkins, Docker & Kubernetes
Why Choose This Project?
In modern DevOps practices, Continuous Integration (CI) and Continuous Deployment (CD) are critical for delivering high-quality software quickly and reliably. By combining Jenkins (automation server), Docker (containerization), and Kubernetes (orchestration), this project demonstrates a scalable and automated delivery pipeline that ensures rapid builds, testing, and deployment.
What You Get
-
End-to-end automated software delivery pipeline.
-
Jenkins pipeline jobs for build → test → deploy.
-
Docker images for consistent app runtime.
-
Kubernetes deployment for scalability & resilience.
Key Features
| Feature | Description |
|---|---|
| Continuous Integration | Jenkins automatically builds code on every commit (GitHub/GitLab). |
| Automated Testing | Unit, integration, and system tests run inside pipeline stages. |
| Dockerized Builds | Application packaged as Docker images for portability. |
| Kubernetes Deployment | Automated deployment to Kubernetes cluster with rolling updates. |
| Monitoring & Logs | Pipeline status monitoring with Jenkins UI + Kubernetes logs. |
| Notifications | Slack/Email alerts on build success or failure. |
| Rollback Support | Kubernetes ensures quick rollback on failed deployments. |
Technology Stack
Pipeline & Orchestration
-
Jenkins – CI/CD pipeline automation.
-
Docker – Containerization for consistent builds.
-
Kubernetes (K8s) – Container orchestration, scaling, and load balancing.
Source Code & Repo
-
GitHub / GitLab (version control + webhook triggers).
Testing
-
JUnit / PyTest / Mocha (based on app language).
Infrastructure
-
Cloud (AWS EKS, GCP GKE, Azure AKS) or on-prem Kubernetes cluster.
-
DockerHub / AWS ECR / GCP Artifact Registry for image storage.
Working Flow
-
Developer commits code → Pushed to GitHub/GitLab repo.
-
Jenkins Webhook Trigger → Build job starts automatically.
-
Build & Test Stage → Jenkins pulls repo → Runs tests → Builds Docker image.
-
Docker Push Stage → Image pushed to DockerHub/ECR/ACR.
-
Deploy Stage → Jenkins applies Kubernetes manifests (
kubectl apply). -
Kubernetes Cluster → Pods are updated with the new image (rolling update).
-
Monitoring & Alerts → Jenkins + Kubernetes logs, Prometheus + Grafana dashboards.
