# Serves: R-NET-05 (egress is a declared property; every workload declares its class)
|
|
# Spec: docs/03 "Egress is a declared property"; docs/13 `egress: internet | vpn`.
|
|
#
|
|
# The egress class is enforced OUTSIDE the service (Cilium Egress Gateway selects
|
|
# pods by label -> steers `vpn` pods through the shared PIA/Gluetun gateway, ADR-0013).
|
|
# For that steering to be possible the label MUST exist on the pod and be one of the
|
|
# two valid classes. A missing/typo'd class would silently fall back to the plain
|
|
# internet path -- a fail-OPEN egress leak -- so we require it explicitly (fail-closed
|
|
# posture, coordination-protocol.md #8).
|
|
#
|
|
# Matches Pods; pod-controller autogen extends to Deployment/StatefulSet/etc.
|
|
# LABEL KEY is a PROPOSED contract owned jointly with WS-NET/WS-GITOPS -- see
|
|
# platform/kyverno/labels.md and the report's escalation note. The VALUES
|
|
# (internet|vpn) are fixed by docs/03 + docs/13.
