GitHub Actions\n\n* **Workflow:** `.github/workflows/ci-cd-multi-microservice.yml`\n* Triggered on push or pull request to `main` branch.\n* Steps:\n\n  1. Checkout code\n  2. Configure AWS credentials\n  3. Build Docker images per service\n  4. Push images to AWS ECR\n  5. Deploy to EKS using `kubectl apply`\n\n### 2. Jenkins\n\n* Pipeline defined in `Jenkinsfile`.\n* Supports parallel builds for all microservices.\n* Deploys images to AWS ECR and updates Kubernetes manifests.\n\n### 3. Tekton\n\n* Tekton pipelines located in `tekton/`.\n* Modular and declarative CI/CD tasks.\n* Compatible with Tekton Hub resources for shared tasks.\n\n---\n\n## Build \u0026 Deploy Locally\n\n### Java App\n\n```bash\ncd services/java-app\nmvn clean package\ndocker build -t java-app:latest .\n```\n\n### Node.js App\n\n```bash\ncd services/node-app\nnpm install\nnpm test\ndocker build -t node-app:latest .\n```\n\n### Python App\n\n```bash\ncd services/python-app\npip install -r requirements.txt\ndocker build -t python-app:latest .\n```\n\n### Deploy to Kubernetes\n\n```bash\nkubectl apply -f k8s/java-app-deployment.yaml\nkubectl apply -f k8s/node-app-deployment.yaml\nkubectl apply -f k8s/python-app-deployment.yaml\nkubectl apply -f k8s/multi-app-ingress.yaml\n```\n\n---\n\n## AWS Integration\n\n* **ECR:** Stores Docker images per microservice.\n* **EKS:** Hosts microservices using Kubernetes.\n* **CloudWatch / Prometheus:** Observability for apps \u0026 cluster.\n\n**ECR URIs Example:**\n\n```\njava-app: 676509179952.dkr.ecr.ap-south-1.amazonaws.com/java-app\nnode-app: 676509179952.dkr.ecr.ap-south-1.amazonaws.com/node-app\npython-app: 676509179952.dkr.ecr.ap-south-1.amazonaws.com/python-app\n```\n\n---\n\n## Tekton CLI Commands\n\n* `tkn pipeline list` — List available pipelines\n* `tkn pipelinerun start \u003cpipeline\u003e` — Run a pipeline\n* `tkn task list` — List available tasks\n* `tkn taskrun describe \u003ctaskrun\u003e` — Inspect a task run\n\n\u003e Configure `tkn` as a `kubectl` plugin for seamless CLI integration.\n\n\u003e Conect to ZeroTrustOps SecTL WebHook for auto scan. \n\n---\n\n## Screenshots\n\n### AWS EKS\n\n![EKS Screenshot](https://github.com/user-attachments/assets/fef87f12-7da9-45fc-8dcd-64b82a9ebf5f)\n\n### AWS ECR\n\n![ECR Screenshot](https://github.com/user-attachments/assets/2aeadcdd-55dc-499c-bc00-292ae8fefd49)\n\n### GitHub Actions\n\n![GitHub Actions Screenshot](https://github.com/user-attachments/assets/2a6ea9b2-aacd-48d8-893a-f626094c733c)\n\n### Java App Running\n\n![Java App Screenshot](https://github.com/user-attachments/assets/e7f1ca29-932b-491c-81fd-840fbcd230b9)\n\n### Node App Running\n\n![Node App Screenshot](https://github.com/user-attachments/assets/75ac5cc4-b345-4a78-8853-52e8419dd6bc)\n\n### Python App Running\n\n![Python App Screenshot](https://github.com/user-attachments/assets/2b86aa47-ad17-4750-94e8-33318c57b3bf)\n\n---\n\n## Maintenance \u0026 Cleanup\n\n### Delete Kubernetes Resources\n\n```bash\nkubectl delete deployment java-app node-app python-app\nkubectl delete service java-app-service node-app-service python-app-service\nkubectl delete ingress multi-app-ingress\n```\n\n### Delete AWS ECR Images\n\n```bash\naws ecr batch-delete-image --repository-name java-app --image-ids imageTag=latest\naws ecr batch-delete-image --repository-name node-app --image-ids imageTag=latest\naws ecr batch-delete-image --repository-name python-app --image-ids imageTag=latest\n```\n\n### Delete EKS Cluster \u0026 Nodegroups\n\n```bash\naws eks delete-nodegroup --cluster-name polyci-cluster --nodegroup-name \u003cnodegroup\u003e\naws eks wait nodegroup-deleted --cluster-name polyci-cluster --nodegroup-name \u003cnodegroup\u003e\naws eks delete-cluster --name polyci-cluster\n```\n\n---\n\n## References\n\n* [AWS EKS Documentation](https://docs.aws.amazon.com/eks/latest/userguide/what-is-eks.html)\n* [AWS ECR Documentation](https://docs.aws.amazon.com/ecr/latest/userguide/what-is-ecr.html)\n* [Tekton Pipelines](https://tekton.dev/docs/)\n* [Kubernetes Documentation](https://kubernetes.io/docs/home/)\n\n---\n\n## License\n\nApache-2.0 © 2025 [Debasish-87](https://github.com/Debasish-87)\n\n---\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdebasish-87%2Fpolyglot-cicd-engine","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdebasish-87%2Fpolyglot-cicd-engine","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdebasish-87%2Fpolyglot-cicd-engine/lists"}
