What is two-tier service accounts in Kubernetes for AI agents?

It's a proxy pattern: Central service account with tight perms, child accounts per agent inheriting access. Isolates risks, centralizes control.

How do I implement agent credential management in K8s?

Create proxy SA + Role, bind children to it. Use `serviceAccountName` in deployments. Automate with Helm/Operators for scale.

Does two-tier fix AI agent 403 errors?

Yes, if creds/token mounting's the culprit. Ensures consistent, isolated access without over-privileging.
