Kubernetes Product Auth Architecture

Design authentication and authorization for multiple Kubernetes products using Envoy, JWT, SSO, service tokens, and federated credentials.

Maintained by Vishal Anand.

A Kubernetes platform often has many products: dashboards, admin tools, data explorers, job APIs, and internal services. This course shows how to centralize shared auth checks at Envoy while keeping product-specific permissions close to the owning service.

Learning path

Continue from concept to implementation

These course modules place this topic in context, connect it to adjacent decisions, and provide the practical next step.

Module 6

Access Tokens, Service Tokens, and Federated Credentials

Handle humans, services, jobs, and cloud/data-platform access without treating every token the same.

100 minutes | 4 learning objectives

Module 7

Authorization Policy, Headers, and Product Boundaries

Forward trusted identity context without letting products trust spoofed headers.

95 minutes | 4 learning objectives

Module 8

Production Design: Security, Performance, and Scale

Turn the pattern into a production-grade design with latency budgets, failure modes, audits, and rollout plans.

Practical outcomes

What the recommended module teaches

  • Evaluate the performance cost of JWT validation and external authorization
  • Design high availability for Envoy, JWKS, IdP, and auth services
  • Choose fail-closed, fail-open, and degraded-mode behavior deliberately
  • Write a production rollout checklist for centralized auth migration
