Kubernetes RBAC Security
Kubernetes RBAC (Role-Based Access Control) controls who can do what in K8s. Define Roles (permissions), Bindings (assign roles to users/services), Service Accounts (pod identity). Mastery takes 6-8 weeks. Practitioners earn 35-45% premium because they prevent breaches. The 2% who architect zero-trust K8s (least-privilege everything) are highly valued in security roles.
What is Kubernetes RBAC Security
Kubernetes RBAC is the authorization system that determines who can perform what actions on which resources. It uses Roles (define permissions), RoleBindings (assign roles to users/service accounts), and Service Accounts (pod identity). When a user or pod makes an API call to K8s, the API server checks RBAC: is this entity authorized? If yes, proceed. If no, 403 Forbidden. RBAC is declarative: define in YAML, apply to cluster. Scales from single developer to multi-team organizations with different permission levels.
