# .gitea/workflows/spdk-image.yaml
#
# Builds the SPDK NVMe/TCP target image (serving stack) from serving/spdk and
# pushes it to the registry, so serving hosts just `docker compose pull` it.
# There is no official spdk/spdk image to pull, so we compile a pinned release
# once here (slow: ~10-20 min, needs a runner with enough CPU/RAM/disk).
#
# Runs only when the SPDK image inputs change (path filter) or on demand — not
# on every commit. Bump SPDK_VERSION (or use the manual run input) to roll SPDK.
#
# Required Gitea repo secrets: PACKAGE_USER, PACKAGE_TOKEN (registry creds).
