Lessons Learned Evolving K8s Extensions: The Future Of Tekton Pipelines
summary
Tekton prototypes a co-located pipeline run that executes an entire Pipeline inside one Pod using an emptyDir volume instead of PVCs, turning tasks into container groups rather than separate Pods. Experiments show ~60% faster on a tiny web app, ~20% faster (≈1.5 minutes saved) on Tekton’s CI pipeline, and about a 50% reduction for a synthetic 50 tasks pipeline. Tradeoffs include one service account per Pod, immutable container lists at creation, and CRD size limits that need more measurement and dogfooding.
