This repository contains a CI/CD pipeline for building, testing, containerizing, and deploying a Java backend API using GitHub Actions, Docker, and Kubernetes.
GitHub Actions: Automates the build, test, and deployment process.
Maven: Builds and manages dependencies for the Java project.
Docker: Creates and pushes container images to Docker Hub.
Kubernetes: Orchestrates the deployment of the application.
Minikube: Runs a local Kubernetes cluster for testing deployments.
JDK 17: Java Development Kit used for compiling and running the application.
This pipeline consists of three jobs:
Build & Test: Compiles the Java project using Maven and runs unit tests. Docker Build & Push: Builds a Docker image and pushes it to Docker Hub. Deploy to Kubernetes: Deploys the application to a Kubernetes cluster.
The pipeline is triggered on:
- Pushes to the
mainbranch. - Pull requests targeting the
mainbranch.
-
Checks out the repository.
-
Sets up JDK 17.
-
Builds the Java project with Maven.
-
Runs unit tests.
-
Debugs by listing the target directory.
-
Checks out the repository.
-
Sets up JDK 17.
-
Builds the project with Maven (skipping tests).
-
Logs into Docker Hub using stored secrets.
-
Builds a Docker image for the application.
-
Pushes the Docker image to Docker Hub.
-
Checks out the repository.
-
Starts a Minikube cluster.
-
Deploys the application using Kubernetes manifests.
-
Monitors the deployment rollout.
After deployment, verify the application is running using:
-
Check Kubernetes Pods
kubectl kubectl get pods -
Check Logs
kubectl logs -l app=task-api -
Check Service
kubectl get services
This pipeline automates the entire process of building, testing, containerizing, and deploying the Task Manager application to a Kubernetes cluster, ensuring a smooth and dependable deployment workflow.
