inecs f1289858fd Clear Web UI session on 401 and keep API/Ingress errors as JSON.

Include the missing resource id in not-found messages, expire auth to Guest
after 401, and document Ingress annotations so nginx does not rewrite 404/405
bodies into branded HTML.

Troubleshooting

`/health/ready` is 503

Postgres not up or wrong DATABASE_URL
Migrations not applied — check migrate initContainer / make db-migrate
Helm: kubectl logs on the simulator pod (migrate init)

Auth 401

Wrong user/password/domain (Default)
Project scope missing for project-scoped APIs
Token from a different simulator instance (reseed rotates IDs)
In the Web UI, HTTP 401 clears the local Keystone session and shows Guest in the header; sign in again from Environment

Ingress returns branded HTML 404 / nginx 405 instead of JSON

The simulator answers API errors as JSON (error / itemNotFound / message). If you see a site HTML “page not found” or plain nginx 405 page, the Ingress / reverse proxy replaced the upstream body (often via custom-http-errors on the ingress-nginx controller).

Fix on the Ingress for this host (see helm/openstack-api-simulator/values-ingress-example.yaml):

annotations:
  nginx.ingress.kubernetes.io/proxy-intercept-errors: "false"
  nginx.ingress.kubernetes.io/custom-http-errors: "502,503"

Then re-check with Accept: application/json. A missing compute instance should look like JSON (not HTML), for example:

{"itemNotFound": {"code": 404, "message": "Instance 'missing-id' could not be found"}}

Correct authenticated mutation (OpenStack)

Use a Keystone token header and JSON body (OpenStack APIs are JSON, not form-urlencoded):

# after POST /v3/auth/tokens → X-Subject-Token
TOKEN=...
curl -sS -X POST "https://HOST:8774/v2.1/servers" \
  -H "X-Auth-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -d '{"server":{"name":"demo","flavorRef":"...","imageRef":"...","networks":[{"uuid":"..."}]}}'

Keystone/UI via Ingress is usually :443→5000; Nova and other service ports still need port-forward / LoadBalancer / TCP Ingress unless you only call through the multi-port gateway Service.

Empty lists after lifecycle probe

Lifecycle DELETE can remove demo-scoped rows. Reload:

make seed-demo
# or Helm:
kubectl exec deploy/… -- python -m app.openstack.seed_cli --profile demo

Wrong service answers on a port

Confirm gateway headers:

curl -sI http://127.0.0.1:8774/ | grep -i openstack

Expect X-OpenStack-Service: nova. If you hit simulator :8080 directly, set X-OpenStack-Route-Service / X-OpenStack-Service yourself.

Helm port-forward to 5000 fails

Forward the gateway Service, not the simulator Service:

kubectl port-forward svc/<release>-openstack-api-simulator-gateway 5000:5000

Pack activate 404 / empty ops

Ensure contracts/openstack/<series>/ exists in the image and OPENSTACK_SERIES is a known series name.

Client catalog ports unreachable

Catalog advertises per-service ports. With only Ingress on :443→5000, Nova :8774 is not automatically published. Port-forward or expose the gateway Service (see kubernetes.md).
