Cloudflare's bot-management incident on 2026-05-12 took out docker.io blob
pulls twice in one day — first for python:3.12-slim (mirrored in 5a2ebf9),
then again for golang:1.25 when the PR 1 coraza-spoa build hit the same
R2-via-Cloudflare failure on the build stage's base image.
Restructure .gitea/workflows/mirror-base-image.yaml into a matrix that
iterates over a list of (src, dst_path, tag) entries. Adding a new base
image is now a one-line matrix entry. fail-fast: false so one image's
upstream being down doesn't block refreshing the others.
Switch coraza-spoa/Dockerfile's build stage FROM to the in-house golang
mirror. Runtime FROM (gcr.io/distroless/static-debian12:nonroot) stays
on upstream — distroless is on Google's registry, separate from Docker
Hub's Cloudflare R2 setup, and didn't fail during today's incident.

# Coraza-SPOA sidecar for haproxy-manager.

|
|
# Layout: built from upstream source. main.go is at the repo root; CRS rules
|
|
# are bundled into the binary at build time (referenced as @owasp_crs/), so
|
|
# the CRS version is whatever ships with the pinned coraza-spoa tag.
|
|
#
|
|
# Pin: review the upstream CHANGELOG (https://github.com/corazawaf/coraza-spoa/releases)
|
|
# before bumping. New tags can ship newer CRS, which can introduce new rules
|
|
# whose IDs fall into the "enforce day-one" ranges in overrides.conf — verify
|
|
# those are still high-confidence before promoting a new tag to prod.
