Freedesktop SDK custom containers

Curated Resource Optimization: Freedesktop SDK images are compiled on-demand in the homelab. Only OCI layers actively scheduled by the active testing-lab pipeline (specifically fsdk/lab-runner and fsdk/qemu-img) are built and pushed to the writable Zot registry to minimize cluster CPU footprint and NVMe storage consumption. The remaining unbuilt containers stay fully tracked as elements and can be compiled locally.

fsdk/lab-runner

The core testing-lab executor container. Contains behave, dogtail, qecore, and GNOME Shell AT-SPI verification runtimes.

Data Integrity Posture

Registry-derived contract · v2

Build source

fallback

Status

online

Evidence-backed authenticity: Userspace container listings, repository namespaces, and active caching layers are retrieved directly from the live Zot local registries on ghost (:30500 and :30501) at build-time.
Defensive offline fallback: In case the homelab registries are unreachable during compilation, the page automatically resolves to a local verified snapshot of active container layers, ensuring build resiliency.
No synthetic data: Registry sizes, repositories, and tags are never fabricated. Only verified elements published in the catalog are marked as active.
