+# oauth2-proxy: Google OAuth at the nginx ingress layer.
+# Ref: https://medium.com/@hrlimaye/google-oauth2-with-kubernetes-nginx-controller-d7a0a3e62e1b
+#
+# Flow:
+#   1. Request hits nginx ingress for Kibana (ingress-kibana.yaml).
+#   2. nginx calls auth-url -> oauth2-proxy /oauth2/auth (200 = pass, 401 = redirect to signin).
+#   3. On 401, nginx redirects to auth-signin (oauth2-proxy /oauth2/start) -> Google login.
+#   4. Google redirects back to /oauth2/callback (served by ingress-oauth2-proxy.yaml).
+#   5. Authenticated request proceeds to Kibana.
+#
+# Requires Secret "oauth2-proxy-google" (see oauth2-proxy-secret.example.yaml).
+# Google OAuth app: Authorized redirect URI must be set to:
+#   http://kibana-prd-observability.prd.meesho.int/oauth2/callback
