How To Dev

Introduction In the previous article, I provided instructions on setting up CI/CD with Jenkins and Gitlab to deploy a NestJS project to AWS EKS. Now, I will provide similar guidance for deploying a project using the NextJS framework to AWS ECS, triggering an auto build on Jenkins when pushing code to Gitlab, and running tests for the project before deployment. A summary of the steps involved will be as follows: Build the Docker image for the NextJS project and push it to AWS ECR. Deploy that Docker image to AWS ECS. Set up Jenkins to connect with Gitlab. When code is pushed to Gitlab, Jenkins will trigger an auto build of the steps defined in the Jenkinsfile, including: Pulling the new code from Gitlab. Running tests for the project. If the test fails, stop the deployment process. If the test passes, proceed to the next step. Building the Docker image with the new code and pushing it to AWS ECR. Deploying to AWS ECS by restarting the service, which will use the latest Docker image to d...

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...
