Setting up a CI/CD Pipeline for NestJS with Jenkins, Gitlab, and AWS EKS
Introduction Jenkins is a leading open-source automation tool that enables Continuous Integration (CI) and Continuous Delivery (CD). With its vast plugin ecosystem, Jenkins helps automate every stage from build and test to deploy, reducing manual errors and increasing software development speed. Gitlab is not only a Git-based source code repository but also provides a comprehensive DevOps platform. Gitlab's key advantages are tight repository management, built-in Webhooks to trigger external pipelines, and powerful project management and code review features that help teams collaborate effectively. In this article, I will guide you through setting up Jenkins to automatically pull source code from Gitlab and deploy to AWS EKS. The summary of the steps will be as follows: Build a source docker image from the NestJS source code and push it to AWS ECR Create an EKS Cluster and deploy with that docker image Setup configuration for Jenkins Add a Jenkinsfile to the NestJS project and push...
