# Ingress — Keycloak (namespace: sso)
#
# kc.coulomb.social — SSO portal, OIDC/SAML endpoints, user login
#
# TLS: cert-manager issues the certificate via the letsencrypt-prod ClusterIssuer
# (T02). Public DNS for kc.coulomb.social must resolve to the cluster's external
# IP before cert-manager can complete the ACME HTTP-01 challenge.
#
# Middlewares:
#   keycloak-rate-limit      — 100 req/min per IP (all paths)
#   keycloak-admin-allowlist — restrict /admin/* to VPN/office IPs (see middleware.yaml)
#   keycloak-hsts            — inject HSTS header on all HTTPS responses
#
# Config points (see CONFIG.md):
#   CP-NK-004  kc.coulomb.social

# ── Main portal — kc.coulomb.social ──────────────────────────────────────────
