Chapters
Pod Security Standards
Understand the three PSS levels (Privileged, Baseline, Restricted) and how Pod Security Admission enforces them across namespaces.
Zero-Trust Network Policies
Lock down pod-to-pod communication with NetworkPolicies. Learn to implement deny-all defaults and allow only explicit traffic.
RBAC Least-Privilege Access Control
Configure Roles, ClusterRoles, and Bindings to enforce least-privilege access for users and service accounts.
Resource Requests and Limits
Set CPU and memory requests/limits correctly to avoid OOM kills and ensure fair scheduling across nodes.
Deployment Strategies
Compare Rolling, Blue-Green, Canary, and Progressive Delivery strategies. Pick the right one for your risk tolerance.
