kcp is a Kubernetes-like control plane focusing on:

• A control plane for many independent, isolated “clusters” known as workspaces
• Enabling API service providers to offer APIs centrally using multi-tenant operators
• Easy API consumption for users in their workspaces

kcp can be a building block for SaaS service providers who need a massively multi-tenant platform to offer services to a large number of fully isolated tenants using Kubernetes-native APIs. The goal is to be useful to cloud providers as well as enterprise IT departments offering APIs within their company.

NB: In May 2023, the kcp project was restructured and components related to workload scheduling (e.g. the syncer) and the transparent multi cluster (tmc) code were removed due to lack of interest/maintainers. Please refer to the main-pre-tmc-removal branch if you are interested in the related code.

For Users: Follow our Setup & Quick Start guide to download and run kcp.

For Developers: To build and run kcp from source:

# Build and run from source:
go run ./cmd/kcp start

# In another terminal:
export KUBECONFIG=.kcp/admin.kubeconfig && kubectl get workspaces
