# Istio ext_authz Policies - Forward Auth via Authentik
|
|
# ==========================================================================
|
|
#
|
|
# These policies protect services that don't have native OIDC integration.
|
|
# Istio's ext_authz filter calls Authentik's forward-auth endpoint before
|
|
# allowing traffic through.
|
|
#
|
|
# Services with native OIDC (GitLab, ArgoCD, Grafana, n8n, Home Assistant,
|
|
# Rancher, Nextcloud) do NOT need ext_authz - they handle auth themselves.
|
|
#
|
|
# IMPORTANT: CUSTOM action does NOT support 'from' or source-based matching.
|
|
# We use 'to.operation.hosts' to restrict to external hostnames only.
|
|
# Internal service-to-service traffic uses k8s DNS names (*.svc.cluster.local)
|
|
# which won't match, so it bypasses ext_authz and hits ALLOW policies instead.
|
