How we build OKD (Kubernetes distro) using Tekton
summary
Builds a full OKD distribution from OS to operators using Tekton Pipelines and coreos workflows, producing per-architecture cloud images and ISOs (currently x86 native only, ARM planned) and aiming to auto-compose multi-arch manifest lists via event triggers/interceptors. Uses a COSA-based toolchain (coreos-assembler) and GitOps with Argo CD, runs pipelines locally on kind or on a Mass Open Cloud build farm (donated ~2,000 servers) for production, and migrates component releases from Prow into Tekton; pipelines already sign, mirror and publish release payloads.
