The Phase-1 NetworkPolicy from DEV-614 allowed ingress only from the `pangolin` namespace, under the mistaken assumption that Traefik runs there. In this cluster Traefik lives in `kube-system`; Pangolin only renders the Traefik dynamic config and does not sit in the request path. The policy therefore blocked external calls to `approval.proofedmesh.basicstack.de`, which 502'd at Traefik. Point the ingress rule at `kube-system/app.kubernetes.io/name=traefik` and update the inline comment to match reality. Verified: `curl -sS https://approval.proofedmesh.basicstack.de/healthz` → `{"status":"ok"}` (HTTP 200, LetsEncrypt cert via Traefik ACME). Co-Authored-By: Paperclip <noreply@paperclip.ing>

# NetworkPolicy for approval-service.
|
|
#
|
|
# Cluster-wide NetworkPolicy enforcement is already active on BasicStack
|
|
# (see cluster memory on NetworkPolicy activation). Any pod in agent-trust
|
|
# without a policy is isolated by default; this file is the explicit
|
|
# allow-list for approval-service.
|
|
#
|
|
# Ingress: only from the Pangolin ingress edge (public traffic terminates
|
|
# at Pangolin/Traefik; nothing in-cluster calls approval-service
|
|
# directly in Phase 1).
|
|
# Egress: signing-service (:8081) + transparency-log (:8080) in
|
|
# agent-trust, Pocket-ID (:1411) for OIDC discovery/JWKS, DNS, and (once
|
|
# trust-pg lands) a Postgres :5432 egress to trust-pg in agent-trust.
