Implementing CI/CD pipelines with Harness enhances software development by automating processes, leading to faster deployments, efficient bug identification, and easier rollback procedures. This approach reduces manual tasks, improves team productivity, and refines the overall software delivery pipeline. While continuous integration (CI) focuses on automating code build and testing, continuous delivery (CD) automates the release process, ensuring code is always ready for deployment. When combined with DevOps practices, CI/CD fosters a streamlined workflow, reduces inefficiencies, and facilitates more frequent software updates. The article provides a detailed guide on setting up CI/CD with Harness, including prerequisites like a free Harness account and access to a Kubernetes cluster. By walking through a simple "Hello World" Node.js application, it illustrates the build and deployment processes, emphasizing the advantages of using Harness for CI/CD. It underscores the importance of CI/CD in a DevOps strategy, highlighting its role in automating code review and fostering continuous improvement within development teams.
