Namespace Multi-Tenancy, But All The Problems Related To It

on YouTube ↗05m

" summary

Kubernetes hits scale pain around 200–300 microservices, where namespaces and clusters both fail; Project Capsule wraps multiple namespaces into a tenant that enforces replicated RBAC, network policies (Calico, Cilium), and per-tenant resource pools to prevent quota overrun. It integrates with Argo CD/GitOps, Rancher, Velero and exposes tenant-level configuration so owners self-serve while admins control boundaries. Maintainer claims this reduces cluster sprawl, cost surprises, and developer friction by combining native primitives with a lightweight control plane.
