Baseline for the Kong replacement on api.riotpiao.com. Brings the working tree under version control for the first time: gateway source, the task board that drives the agent runs, test fixtures, and K8s manifests. Anchor the gateway ignore rule to the repo root. Unanchored, "gateway" also matched the cmd/gateway/ source directory, so the program entrypoint was excluded from every commit.

# 6.5 — Cutover: repoint Ingress `api/api` (GREEN)
|
|
|
|
Phase: 6 — Deploy and cutover
|
|
Stage: GREEN
|
|
Depends on: [2.8](2.8-kong-parity-test.md), [6.4](6.4-deploy-alongside-kong.md)
|
|
|
|
THIS is the cutover. Ingress `api/api` catch-alls `/` on `api.riotpiao.com`; today its
|
|
backend is `kong-proxy:80`. Changing that one backend moves all live traffic to the
|
|
gateway. Reverting is the same one-line change back to `kong-proxy:80`, committed and
|
|
synced — Kong stays running and untouched, so the revert takes effect in seconds.
|
|
|
|
Preconditions, all required before starting:
|
|
|
|
- [ ] 2.8 Kong parity is passing — gateway and Kong return equivalent responses for every route in the migration inventory, including a streaming request and a mid-stream disconnect
|
|
- [ ] 6.4 is complete: the gateway is healthy in-cluster against the real predictors, and Prometheus is scraping it
|
|
- [ ] The inventory has been re-verified immediately beforehand. Kong's Deployment has eleven ReplicaSets and is being actively iterated; a stale inventory is a stale plan
|
|
- [ ] Kong remains deployed and serving-capable throughout. Nothing about Kong is deleted in this task
|
|
|
|
The change itself:
|
|
|
|
- [ ] The `api/api` Ingress backend becomes the gateway Service, changed in git and synced by Argo. No `kubectl apply`, no `kubectl edit` (G7)
|
|
- [ ] The nginx annotations stay exactly as they are: `proxy-read-timeout: 3600`, `proxy-send-timeout: 3600`, `proxy-buffering: off`, `proxy-body-size: 0`. These are what make token streaming work and the gateway needs the same treatment
|
|
- [ ] The revert is a single-line commit reverting the backend to `kong-proxy:80`, and it has been rehearsed at least once
|
|
- [ ] After the change, public streaming works end to end through nginx, unbuffered
|
|
- [ ] pi keeps working on the legacy `/v1/{reasoning,ornith,qwen}/chat/completions` aliases
|
|
- [ ] A soak period follows, watching gateway metrics, rejection counters and pi traffic. Do not proceed to 6.6 until the soak is clean
|

## Verify
|
|
|
|
```bash
|
|
kubectl -n api get ingress api -o jsonpath='{.spec.rules[0].http.paths[0].backend.service.name}{"\n"}'
|
|
# expected: the gateway Service, no longer kong-proxy
|
|
|
|
curl -sN -X POST https://api.riotpiao.com/v1/chat/completions \
|
|
-H 'content-type: application/json' \
|
|
-d '{"model":"reasoning","stream":true,"messages":[{"role":"user","content":"count to 5"}]}'
|
|
# expected: incremental data: chunks over time through nginx, ending in data: [DONE]
|
|
|
|
curl -s -o /dev/null -w '%{http_code}\n' -X POST https://api.riotpiao.com/v1/reasoning/chat/completions \
|
|
-H 'content-type: application/json' -d '{"messages":[{"role":"user","content":"hi"}]}'
|
|
# expected: 200 — pi's legacy alias still works
|
|
|
|
kubectl -n api get deploy kong-kong -o jsonpath='{.status.readyReplicas}{"\n"}'
|
|
# expected: 2 — Kong still running and ready, so the revert is one commit away
|
|
```
