Kubernetes can be used as a Continuous Integration/Continuous Delivery (CI/CD) platform, leveraging its scalability and flexibility to deploy CI/CD pipelines. A CI/CD pipeline is an automated set of processes that software developers use to write, merge, compile, test, and deploy code. Kubernetes CI/CD offers benefits such as simpler deployment, built-in scalability, extensive control, lower costs, and the ability to implement GitOps. To build a CI/CD pipeline on Kubernetes, one can either deploy conventional CI/CD tools or use "Kubernetes-native" CI/CD software that takes advantage of native Kubernetes features. Popular CI/CD tools for Kubernetes include Tekton. Best practices for CI/CD and Kubernetes include setting quotas and limits, creating separate namespaces, isolating CI/CD operations, enabling autoscaling, backing up data and configurations, and using observability platforms like groundcover to monitor performance. While every CI/CD pipeline may not need to run on Kubernetes, it can help boost efficiency, scalability, and control over software development and deployment processes.
