claude-botandClaude Opus 5 deaf4b6a03 fix(cni-eval): make the Antrea test runnable, and unable to reach prod
Nothing here is merged: bootstrap.sh on master is the production rebuild
path. The test runs from this branch, in the vmtest Job.

Five defects in the first version, each found by checking it against the
real environment rather than by running it:

- run-bgp-test.sh used the default kubeconfig. vmtest exports its
  isolated KUBECONFIG only inside its own process, so a script started
  afterwards from another shell would have targeted production, with a
  single DaemonSet-existence check in the way. It now refuses without an
  explicit KUBECONFIG, refuses an API on k8s.renner.uno or 10.2.40.0/24,
  and refuses nodes named k8s-1..3.

- The procedure could not work: vmtest destroys its VMs on exit, so a
  separate test run afterwards finds no cluster. With CNI=antrea the test
  now runs inside the vmtest phase, while its KUBECONFIG is live.

- The session count read FRR's text summary for "Estab". FRR shows an
  established peer there as a prefix count, not a state name, so it would
  have reported 0 sessions against a working cluster. It now counts
  bgpState == "Established" in `show ip bgp neighbor json`, the shape
  FRR's own topotests assert.

- Route checks matched substrings of the text table. They now test exact
  prefix keys in `show ip bgp json` .routes, also the topotest shape.

- The FRR pod could not be admitted. Talos enforces PodSecurity baseline
  with only kube-system exempt (read off k8s-1's admission config), and
  baseline rejects NET_ADMIN/NET_RAW. The throwaway namespace is labelled
  privileged, and /etc/frr is seeded into a writable emptyDir by an
  initContainer rather than mounted read-only from the ConfigMap.

The README now runs this as the existing vmtest Job with three values
changed -- branch, CNI=antrea, and the clone source. The GitHub mirror the
stock Job clones is private and the Job has no credentials; the Gitea repo
is anonymously readable.

Verified before committing: antrea chart 2.6.0-2.7.0 exist, so >=2.6.0
resolves to 2.7.0; quay.io/frrouting/frr:10.2.1 exists for amd64; the
branch is on Gitea; the ci-vmtest image carries jq, kubectl and helm;
both scripts pass bash -n; the Job transform renders.

claude-botandClaude Fable 5.1 2818fb56b1 feat(cni-eval): harness to test Antrea as a Cilium replacement (#576)
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Cilium ties pod east-west traffic to the kubelet node IP with no way to
separate them, which is what blocks #576 -- pod traffic cannot leave the
management VLAN while the apiserver endpoints have to stay on it. Three
attempts on the live cluster established that by test rather than
argument: --ipv4-node/--ipv6-node applied via CiliumNodeConfig and
ignored, directRoutingDevice=pod0 logged as detected while routes still
installed via mgmt0, and both routing modes in both families always
keyed to the peer's InternalIP.

Antrea documents one setting covering both the routed and tunnelled
paths. Calico can do it too, and fits worse on the rest: no FQDN egress
policy in OSS (trmnl-ns.yaml needs it) and its nftables dataplane wants
kube-proxy back. Antrea's problem is that its BGP is alpha, and BGP
carries every LoadBalancer VIP here.

So this tests exactly that, and nothing else: does BGPPolicy hold a
session with FRR and advertise the pod CIDRs and LoadBalancer IPs. FRR
runs as an ordinary pod standing in for the UDM, same ASNs as
unifi/bgp.conf, dynamic neighbours via a listen range. The verification
reads FRR's own table rather than Antrea's view of what it advertised,
and the peer address is read from the running pod rather than written
into a manifest.

Stage 1 is free: the QEMU provisioner gives one flat NIC, so it cannot
test interface pinning, but it covers everything else -- that Antrea
runs on Talos at all, that AntreaProxy replaces the kube-proxy Talos
does not ship, that ServiceExternalIP allocates, and that BGP works.
Stage 2 on Hetzner is the only place the two remaining requirements can
be tested, and only runs if stage 1 passes.

The bootstrap.sh change is additive. CNI unset leaves every path
untouched, and CNI=antrea is refused when SITE is homelab, so it cannot
be pointed at the production cluster -- it installs a CNI no HelmRelease
owns.

Antrea >= 2.6 is a floor, not a preference: earlier agents fail to start
on Talos >= 1.7 after its iptables-legacy to iptables-nft switch.

Chart coordinates, Talos values, the BGPPolicy schema and the
ExternalIPPool apiVersion were each read from upstream documentation
rather than recalled.

# CNI evaluation — Antrea
Throwaway-cluster harness for deciding whether Antrea can replace Cilium.
Nothing here is reconciled by Flux and nothing here runs against the homelab.
## Why this exists
Cilium ties pod east-west traffic to the kubelet's Kubernetes node IP and gives
no way to separate them. Three attempts on the live cluster, 2026-09-08:
| Attempt | Result |
|---|---|
| `--ipv4-node`/`--ipv6-node` via `CiliumNodeConfig` | agent logged both flags at startup, still published its `mgmt0` address |
| `directRoutingDevice: pod0` | agent logged `Direct routing device detected direct-routing-device=pod0`, still installed `10.244.2.0/24 via 10.2.40.138 dev mgmt0` |
| tunnel and native mode, v4 and v6 | routes and tunnel endpoints always keyed to the peer's `InternalIP` |
That blocks issue #576: pod traffic cannot leave the management VLAN while the
apiserver endpoints have to stay on it, because both follow the same address.
Antrea documents one setting covering both paths — *"The IP address used for
tunneling **or** routing the traffic across Nodes is decided in the following
order of preference: 1. TransportInterface 2. TransportInterfaceCIDRs 3. The
Node IP."* Calico can do it too. Antrea fits the rest of the requirements
better, with one exception: **its BGP is alpha**, and BGP is load-bearing here —
every LoadBalancer VIP reaches the LAN through it.
So the question this harness answers is narrow: **does Antrea's alpha
`BGPPolicy` actually hold a session with FRR and advertise what the homelab
needs?** If it does not, the answer is Calico and this goes no further.
## Stage 1 — free, local
The QEMU provisioner gives one flat NIC per VM (`site-qemu.yaml`: *"One NIC, no
VLANs"*), so this stage cannot test interface pinning. It tests everything else,
at no cost:
Runs from the `feat/antrea-eval` branch, which is never merged:
`bootstrap.sh` on master is the production rebuild path.
**In the cluster — the way to run it.** The VMs want ~40 GiB, and
`kubernetes/vmtest-job.yaml` records that running this on the workstation
OOM-killed the desktop session. The eval Job is that same Job with three values
changed: the branch, `CNI=antrea`, and the clone source — the GitHub mirror is
private and the stock Job clones it anonymously, so this one clones the
anonymously-readable Gitea repo instead.
```bash
yq -y '(select(.kind == "Job") | .spec.template.spec.containers[0].env[] | select(.name == "BRANCH") | .value) = "feat/antrea-eval"
| (select(.kind == "Job") | .spec.template.spec.containers[0].env) += [{"name": "CNI", "value": "antrea"}]
| (select(.kind == "Job") | .spec.template.spec.containers[0].args[0]) |= sub("https://github.com/konairius/Homelab.git"; "https://gitea.renner.uno/k.renner/homelab.git")' \
kubernetes/vmtest-job.yaml | kubectl apply -f -
kubectl -n vmtest logs -f job/vmtest
```
`-y` is python-yq; go-yq emits YAML without it. The Talos-only phase needs one
secret, `ghcr-pull`; the log prints the exact command to stream it in. The BGP
evaluation runs inside the Job once the nodes are Ready, so PASS/FAIL is in the
log and the VMs are destroyed when it ends. The Job cannot reach this cluster:
it mounts no service account token. Clean up with `kubectl delete namespace vmtest`.
**On a workstation — only with ~40 GiB to spare.** `vmtest` destroys its VMs on
exit and exports its isolated `KUBECONFIG` only inside its own process, so hold
them open and point the test at them explicitly:
```bash
# terminal 1 — needs sudo; holds the VMs until stopped
VMTEST_KEEP=1 CNI=antrea ./kubernetes/bootstrap.sh vmtest
# it prints: talosctl --talosconfig /tmp/tmp.XXXXXX/talosconfig ...
# terminal 2 — the kubeconfig sits next to that talosconfig
KUBECONFIG=/tmp/tmp.XXXXXX/kubeconfig ./kubernetes/cni-eval/run-bgp-test.sh
# teardown
sudo talosctl cluster destroy --name bootstrap-vmtest --state /tmp/bootstrap-vmtest
sudo rm -rf /tmp/bootstrap-vmtest
```
`run-bgp-test.sh` refuses to run without an explicit `KUBECONFIG`, and refuses
any cluster whose API is `k8s.renner.uno` or on 10.2.40.0/24, or whose nodes are
named `k8s-1..3`.
What passing means:
- Antrea installs and runs on Talos at all (needs >= 2.6 — earlier agents fail
to start on Talos >= 1.7 after its iptables-nft switch).
- The cluster reaches Ready with `cluster.proxy.disabled: true`, i.e. AntreaProxy
genuinely replaces kube-proxy, reaching the API through KubePrism.
- `ServiceExternalIP` allocates a LoadBalancer IP.
- `BGPPolicy` establishes with FRR from every node and advertises the pod CIDRs
and the LoadBalancer IP — verified by reading FRR's table, not Antrea's.
`run-bgp-test.sh` deploys FRR as an ordinary pod standing in for the UDM: same
ASNs as `unifi/bgp.conf` (64512/64513), dynamic neighbours via a listen range
rather than named node addresses. Its peer address is read from the running pod
at apply time rather than written into the manifest.
## Stage 2 — billed, only if stage 1 passes
Hetzner nodes have two interfaces and no shared L2, so this is the only place
the two remaining requirements can be tested:
```bash
CNI=antrea ./kubernetes/bootstrap.sh hcloudtest
```
Uncomment `transportInterface` and `trafficEncapMode: hybrid` in
`antrea-values.yaml` first, pointing the former at the private-network NIC while
`site-hcloud.yaml` keeps the kubelet node IP where it is. Then confirm:
- pod east-west leaves on the nominated interface while the node IP does not
move — the property Cilium cannot express;
- `hybrid` encapsulates across a routed network, which is what the Hetzner
cluster needs and the homelab does not.
`hcloudtest` bills by the hour on three cx43s and tears down from its EXIT trap.
If a run is killed before the trap fires, `./kubernetes/bootstrap.sh hcloudclean`
deletes by label.
## What this harness does not cover
- **Policy migration.** 59 `CiliumNetworkPolicy` objects across 34 files, using
`fromEntities`/`toEntities` in 15, typed ICMP in 24, and `toFQDNs` in
`trmnl-ns.yaml`. Antrea has equivalents including FQDN egress in OSS, but the
port is real work and is not tested here.
- **Multus.** Required either way — Antrea's native secondary networks are VLAN
and SR-IOV only, and all six NADs are macvlan or host-device. Unchanged by a
CNI swap.
- **In-place migration.** There isn't one. Talos documents CNI choice as
bootstrap-time only, and a Sidero maintainer's guidance is *"much easier to
redeploy the cluster from scratch"*. Adopting Antrea means a cold rebuild.
## Cleanup
```bash
kubectl delete namespace cni-eval
kubectl delete bgppolicy cni-eval-peer
kubectl delete externalippool cni-eval-lb
```
