Follow-up to 23f3f14. With the checksum annotation in place, `helm
upgrade` did start rolling Kong forward, but the new pod never became
Ready: `rollout status` timed out with
"1 old replicas are pending termination"
Kong's ConfigMap contains the /healthz route correctly, the BackendConfig
is HTTP /healthz, but the Kong process itself refuses to start cleanly
when one of its services has `url: http://127.0.0.1:8000/` -- Kong's own
proxy port. This self-reference apparently trips the declarative-config
parser (undocumented; symptomatic only).
Switch to a RFC-2606 `.invalid` placeholder. The request-termination
plugin short-circuits before any DNS lookup or upstream connection, so
a non-resolvable URL is functionally equivalent and Kong's parser has
nothing to complain about.
Same change in both places we define the /healthz route:
- supabase/helm/knoe-supabase/templates/kong/config.yaml (supabase-kong)
- etc/init_kong.sh inline kong.yml heredoc (knoe-svc-kong)
The knoe-svc-kong backend was already HEALTHY with the self-referential
URL -- different Kong instance, possibly different parser path -- but
keeping the two configs aligned so future edits don't drift.

Follow-up to 391c4f5. Live deploy showed GCE's L7 BackendConfig CRD
hard-rejects type: TCP with:
Error syncing to GCP: error running backend syncing routine:
error ensuring health check:
Protocol "TCP" is not valid, must be one of [HTTP,HTTPS,HTTP2]
The sync never completes, so the LB has no healthy backend and TCP
connections to the public endpoint just close (ERR_CONNECTION_CLOSED).
Fix: switch all three BackendConfigs to type: HTTP with request paths
that return 200:
- supabase-kong & knoe-svc-kong: add a dedicated /healthz route to the
Kong declarative config via the request-termination plugin, which
returns 200 synchronously with no upstream call. Equivalent liveness
semantics to the TCP check we wanted (backend is alive as long as Kong
accepts connections) but over HTTP, which GCE actually accepts.
- supabase/helm/knoe-supabase/templates/kong/config.yaml
- etc/init_kong.sh (inline kong.yml heredoc)
- supabase-studio: Studio returns 301 on / (Next.js default) so we
point the probe at /favicon.ico -- Next.js serves it as a static asset
with 200 unconditionally. Not as clean as a real readiness endpoint
but Studio does not expose one that returns 200 without auth.
- supabase/helm/knoe-supabase/templates/studio/backendconfig.yaml
Verified locally via helm template -f values.generated.json: the
rendered BackendConfigs come out with the HTTP protocol + correct paths,
and the Kong ConfigMap has the healthz service block before the
auth-v1-open service.
