Building a Jenkins Multi-Branch Pipeline for 11 Microservices on AWS EKS
- The article guides on setting up a CI/CD pipeline for an e-commerce app with 11 microservices, each serving distinct functions.
- Microservices offer benefits like independent development, scalability, and fault isolation, making updates easier and improving system reliability.
- Tools used include GitHub for code storage, Jenkins for automation, Docker for containerization, Kubernetes (EKS) for managing containers on AWS, and AWS for cloud infrastructure.
- Steps involve setting up an EC2 instance, configuring AWS permissions, installing essential tools like AWS CLI, kubectl, eksctl, setting up Kubernetes cluster, installing Jenkins, Docker, and configuring Jenkins for the pipeline.
- Configuring Docker and Kubernetes includes creating namespaces, service accounts, roles, and permissions for deploying applications.
- Jenkins setup involves plugins installation, configuring Docker and Kubernetes, creating a multi-branch pipeline, setting up webhooks for automatic triggers, and defining a deployment pipeline.
- The deployment pipeline deploys Docker containers to Kubernetes, allowing the application to be accessible by users without downtime.
- Cleanup steps are provided if complete system removal is needed to avoid ongoing charges, ensuring efficient management of resources.
- The setup enables automated building, containerization, and scalable deployment of microservices, fostering faster innovation and more reliable service delivery.
- Suggestions for enhancement include adding automated testing, monitoring, blue/green deployments, and security scanning for containers.
