# 7.1 — `/cluster/*` proxies to atlas (GREEN)
|
||
|
|
|
||
|
|
Phase: 7 — Additional capability prefixes
|
||
|
|
Stage: GREEN
|
||
|
|
Depends on: [6.5](6.5-cutover.md)
|
||
|
|
|
||
|
|
atlas lives in a separate repo, `riotpiao-backend`. It keeps its own informers and its
|
||
|
|
own RBAC. The gateway proxies to it and holds no Kubernetes credentials of its own —
|
||
|
|
this is G2, and it is the whole reason cluster-read capability lives behind atlas
|
||
|
|
rather than in the edge process.
|
||
|
|
|
||
|
|
- [ ] `/cluster/*` on `api.riotpiao.com` proxies to the atlas Service
|
||
|
|
- [ ] The gateway gains no ServiceAccount token, no kubeconfig and no RBAC as part of this. Any authorization decision about cluster data is atlas's, not the gateway's (G2)
|
||
|
|
- [ ] Path rewriting between the `/cluster` prefix and atlas's own paths is explicit in configuration
|
||
|
|
- [ ] Connect, read and write timeouts and a body cap are explicit for this route, with no silent defaults (G6)
|
||
|
|
- [ ] The route requires authentication, and the token is checked for cluster capability — a token minted for queue access must not read cluster state
|
||
|
|
- [ ] The NetworkPolicy is extended to allow egress to atlas and nothing more
|
||
|
|
- [ ] `/v1/*` behaviour is byte-identical before and after this route is added — the prefixes cannot collide
|
||
|
|
- [ ] Metrics and rejection counters cover this route with its own route label
|
||

## Verify
|
||
|
|
|
||
|
|
```bash
|
||
|
|
curl -s -o /dev/null -w '%{http_code}\n' https://api.riotpiao.com/cluster/healthz
|
||
|
|
# expected: 401 without a token
|
||
|
|
|
||
|
|
curl -s -H "authorization: Bearer $CLUSTER_TOKEN" https://api.riotpiao.com/cluster/healthz
|
||
|
|
# expected: atlas's own response body, proxied unmodified
|
||
|
|
|
||
|
|
curl -s -o /dev/null -w '%{http_code}\n' -H "authorization: Bearer $QUEUE_ONLY_TOKEN" \
|
||
|
|
https://api.riotpiao.com/cluster/healthz
|
||
|
|
# expected: 403 — a queue token does not grant cluster capability
|
||
|
|
|
||
|
|
kubectl -n api get pod -l app=homelab-frontend -o jsonpath='{.items[0].spec.serviceAccountName}{"\n"}'
|
||
|
|
# expected: a ServiceAccount with no RBAC bindings; the gateway still holds no cluster credentials
|
||
|
|
```
