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.
