# NetworkPolicy for dummy-sink.
|
||
|
|
#
|
||
|
|
# Cluster-wide NetworkPolicy enforcement is active on BasicStack (see
|
||
|
|
# cluster memory on NetworkPolicy activation). Pods in agent-trust
|
||
|
|
# without an explicit allow-list are isolated; this file is the
|
||
|
|
# explicit allow-list for dummy-sink per DEV-615.
|
||
|
|
#
|
||
|
|
# Ingress callers (per Phase-1 architecture V1.1 §7):
|
||
|
|
# - testagent-transform — the sole producer of handover deliveries.
|
||
|
|
#
|
||
|
|
# Egress reachable targets (Phase-1 §7 Senken-Vertrag):
|
||
|
|
# - verification-service — chain verification + replay guard.
|
||
|
|
# - signing-service — handover-attestation signing.
|
||
|
|
# - transparency-log — logging the signed handover envelope.
|
||
|
|
# - DNS — kube-dns for service name resolution.
|
||
|
|
#
|
||
|
|
# dummy-sink intentionally does NOT egress Pocket-ID directly; it uses
|
||
|
|
# the Pocket-ID OIDC endpoint via HTTPS/443 as the client_credentials
|
||
|
|
# source for its Bearer token to signing-service. That cluster-external
|
||
|
|
# target is included below.
