Ovstorage Operator Configure Broker Policy

Configure Broker Authorization Policy

Goal

Configure the broker's builtin-auth Layer with deny-by-default TOML rules and rotate those rules without weakening listener authentication.

Recipe

1. Read the authorization policy guide and the broker auth Layer configuration.

2. Configure an authenticated listener and its policy:

   [listener.auth]
   kind = "builtin-auth"
   
   [listener.auth.config]
   jwt_issuer = "https://login.example.com"
   jwt_audience = "ovstorage"
   jwt_jwks_url = "https://login.example.com/.well-known/jwks.json"
   
   [listener.auth.config.policy]
   
   [[listener.auth.config.policy.policy]]
   id = "team-read"
   effect = "allow"
   principal = "team-*"
   operations = ["read", "stat", "list"]
   prefix = "s3://corp-prod/team/"
   

3. Treat the optional policy-document key plugin = "ovstorage-authz-toml" as a retained schema discriminator. It does not load a cdylib, and no other value is supported.

4. Grant copy and rename through their primitive source and destination operations. Keep concrete prefixes segment-aligned.

5. Reload with SIGHUP on Unix. The broker validates a fresh configuration and atomically swaps the active host; invalid configuration leaves the current host running. Restart on Windows.

6. Confirm allow, deny, and policy-error metrics through ovstorage_auth_decisions_total.

Boundaries

• Missing listener auth is a startup error.
• auth = "anonymous" is an explicit unauthenticated allow-all choice.
• This skill configures only builtin-auth. An auth-capable plugin wrapper owns its policy schema; broker SIGHUP reconstructs that wrapper from its verbatim config instead of invoking the built-in typed policy reload operation.
• The policy evaluator runs on every request; there is no decision cache or policy-epoch grace window.
