Running continuous integration (CI) workloads on Kubernetes offers substantial benefits but also presents significant challenges due to its inherent complexity. While Kubernetes' scalability and parallelism can align well with the ephemeral nature of CI tasks, issues such as resource allocation mismatches, container building complexities, security restrictions, caching difficulties, and tool layering challenges can complicate the process. Despite these hurdles, Kubernetes remains a popular choice for CI due to its ability to support effective build ecosystems and enhance developer experiences. The text suggests exploring best practices and tools like Buildkite Pipelines to optimize CI/CD workflows on Kubernetes, offering features that promise developer happiness and efficiency.
