Deep Dive: CNCF CI
summary
CNCF.ci runs third‑party CI that builds, deploys and end‑to‑end tests CNCF projects on arm64 on bare metal and x86, reusing upstream Helm charts and project artifacts or rebuilding them. Recent work adds ARM support for Kubernetes, Fluentd, Prometheus (build+deploy stages) and experiments with Envoy; problems include forking upstream release scripts, cross‑compiling Go vs Ruby requiring QEMU emulation for Ruby builds, and finally having to build Envoy natively on arm64 and compile glibc for Alpine before publishing images. Dashboard refreshes daily.
