A practical, in-depth guide to Capsule, the Kubernetes multi-tenancy operator. Learn how Capsule lets many teams safely share one cluster: the Kubernetes multi-tenancy problem (namespaces are not tenants), the operator and webhook architecture, the Tenant model and namespace self-service, tenant-level resource quotas, policy enforcement (network, registries, node selectors), automatic RBAC and Capsule Proxy, security and isolation (soft multi-tenancy and hardening), and operating Capsule at scale.
