claude-botandClaude Opus 5 bb3987ce1c feat(bird): add curl and jq for the peer-list init container
ci/woodpecker/push/build-ci-images Pipeline was successful
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The per-node peer list is rendered from the Kubernetes API rather than written into the repo a second time, so the init container needs an HTTP client that can verify against the API server's CA bundle. busybox wget cannot, and the query is not going to run unverified. Using the same image for the init container and the daemon keeps one lifecycle instead of borrowing a CI image at runtime.

claude-botandClaude Opus 5 3302e2c5cd fix(bird): pin the base image by digest and self-test the binary

Every other Alpine image under ci/images/ pins alpine:3.21 by index digest, and alpine-jq states the reason in the file: the resolved version drifts between restarts of an otherwise pinned image. The first revision used a bare alpine:3.22 tag. 3.22 is still right — bird2 first appears in 3.22/community — so the tag stays and the index digest is added.

heating-can runs --help checks before publishing so a wrong path fails the build rather than the first pod; bird documents --version, so it gets the same guarantee.

Pod east-west follows the peer's Kubernetes InternalIP on mgmt0, and Cilium offers no way to point it elsewhere — established by test in #838, and directRoutingDevice (#837) does not do it. Policy routing does: a rule on the pod source prefixes into a table whose routes carry pod0 next-hops, proven on k8s-1 by counting 4647 packets onto pod0.

Those routes have to be generated, not written down: PodCIDRs are Kubernetes-assigned and do not survive a rebuild in place. BGP between the nodes over pod0 generates them, with the session source as the next-hop.

BIRD rather than FRR. FRR's docs describe 'set table' only as setting a BGP table identifier, never a kernel table; binding bgpd to an address implies --no_kernel and would suppress the route installation the design exists for; and a gatewayless IPv6 device route has no next-hop for its route-maps to match, so the own-CIDR filter could not be uniform. BIRD documents 'kernel table', 'strict bind' without touching the kernel protocol, and an 'ifname' filter attribute that discriminates the local route from the learned ones in both families.

No maintained standalone BIRD image exists: pierky/bird self-declares as lab-only and amd64-only, calico/bird is a Calico-internal artifact expecting confd, slipmesh/bird is five weeks old, srl-labs and ibhde are lab-scoped or on BIRD 1.6. A custom controller would have needed an image of its own anyway, so the build is common to both routes.

Image only. The DaemonSet is 2/3 and the routing rules 3/3, so the table fills before anything reads it.
