What it is
KubeSphere is a distributed operating system for cloud-native application management, using Kubernetes as its kernel. It provides a plug-and-play architecture with extension components and multi-tenant capabilities. The README describes features such as extensible architecture, provisioning Kubernetes clusters, multi-cluster management, DevOps integrations, observability, service mesh, an App Store, edge computing, and support for multiple storage and networking solutions. The project targets enterprise Kubernetes use cases with a GUI and workflow automation.
How it works
KubeSphere adopts a microkernel + extension components architecture. The core contains essential functions, while additional functionality is provided by independently managed extension components that can be managed during system operation. It supports integration with Argo CD for CD status, Jenkins for CI, various storage backends, and networking profiles via multiple CSI plugins and networking options. It emphasizes multi-tenancy with isolated workspaces and role-based access control.
Getting started
Installation is performed via Helm. The README provides commands for installing KS core using helm upgrade --install with a ks-core chart URL, across several release lines:
helm upgrade --install -n kubesphere-system --create-namespace ks-core https://charts.kubesphere.io/main/ks-core-1.1.3.tgz --debug --wait
The README also references an air-gapped installation option for offline environments and notes that additional extensions can be installed after initial installation.
