What a Life! - Understanding the Lifecycle of a Tekton Pipeline
summary
Tekton controller resolves and pins image to digest for reproducibility and forensics, then creates a TaskRun per task and a Pod per TaskRun, with each step running as a container coordinated by an entrypoint binary in /tekton/bin. Steps signal sequencing with files under /tekton/run and each step gets its own volume with per-step volume isolation (others get read-only). An alpha debug breakpoint on failure lets operators exec into a halted step; post-run tools include Tekton Chains for attestations and Tekton Results for archiving.
