Syllabus

Integrating Authentication into Your Cluster

This module explores how to securely integrate authentication mechanisms into Kubernetes clusters, focusing on protocols like OpenID Connect, service accounts, and impersonation strategies. Learners will gain practical skills in configuring authentication for both users and pipelines, ensuring secure access and compliance with enterprise requirements. The module also covers real-world deployment scenarios and best practices for managing identities in cloud-managed and on-premises clusters.

RBAC Policies and Auditing

This module explores how to define, assign, and audit Kubernetes RBAC policies to control access within a cluster. Learners will discover how to map enterprise identities, use RoleBindings, and troubleshoot authorization issues using audit logs and tools like audit2rbac. By the end, you'll be able to implement and debug secure access controls tailored to your organization's needs.

Managing Secrets

This module explores best practices for handling sensitive information in Kubernetes environments, focusing on enterprise-level secrets management. Learners will examine various methods for storing, transmitting, and integrating secrets securely, including the use of external secrets managers and sidecar injectors. Practical strategies for protecting secrets in both storage and transit are discussed, along with real-world deployment scenarios.

Building Multitenant Clusters with vClusters

This module explores the challenges and solutions for implementing multitenancy in Kubernetes using virtual clusters (vClusters). Learners will gain hands-on experience deploying, securing, and managing vClusters, as well as integrating external services and designing a scalable, self-service multitenant platform.

Deploying a Secured Kubernetes Dashboard

This module guides learners through deploying a Kubernetes Dashboard with a focus on security best practices. You will explore common security risks, learn how to use reverse proxies for secure access, and integrate identity management using OpenUnison and OpenID Connect. By the end, you'll be equipped to implement a secured dashboard in your own Kubernetes environment.
