Per ADR-0013: platform/vpn-egress/ = a single shared Gluetun gateway (PIA over WireGuard, built-in kill-switch FIREWALL=on, native port forwarding), namespace (non-app, NET_ADMIN + /dev/net/tun), control-API Service, and a pre-wired (commented) pia-credentials SOPS line. Defined the PIA secret location (platform/vpn-egress, keys username/password → OPENVPN_USER/ OPENVPN_PASSWORD) and updated the SOPS template accordingly. NOT wired into platform/kustomization.yaml (Phase 3, author-first) — deploy needs PIA creds + validation of the egress-steering mechanism (Cilium Egress Gateway → the Gluetun node's wg0; documented in README with options + a fail-closed rationale, deliberately NOT committed as an untested CiliumEgressGatewayPolicy). WireGuard chosen (UDP, protocol != TCP); PIA supports it on all regions and the secret stays username/password. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

# Gluetun — the single shared in-cluster VPN egress gateway (ADR-0013): PIA over WireGuard, with
|
|
# Gluetun's built-in kill-switch/firewall (fail-closed), health checks, auto-reconnect, and native
|
|
# port forwarding for qBittorrent. `vpn`-class pods are steered through this gateway (see README.md
|
|
# "Egress steering" — the Cilium-native mechanism, pending live validation with PIA creds).
|
|
#
|
|
# Credentials: the `pia-credentials` SOPS Secret (keys: username, password). Gluetun uses PIA's
|
|
# username/password (via OPENVPN_USER/OPENVPN_PASSWORD — legacy env names it uses for PIA on BOTH
|
|
# protocols) to authenticate to PIA's API and derive the WireGuard config at runtime — so WireGuard
|
|
# needs no extra key material (ADR-0013).
