What is KubeSphere

English | 中文

KubeSphere is a multi-tenant enterprise-grade container platform built on Kubernetes, with full-stack automated IT operation and streamlined DevOps workflows. KubeSphere provides developer-friendly wizard web UI, helps enterprises to build out a more robust and feature-rich platform, includes most common functionalities needed for enterprise Kubernetes strategy, such as the Kubernetes resource management, DevOps (CI/CD), application lifecycle management, monitoring, logging, Service Mesh (Istio-based), multi-tenancy, alerting and notification, storage and networking, autoscaling, access control, GPU support, etc., as well as multi-cluster management, Network Policy, registry management, security in upcoming releases. KubeSphere is going to be a distributed operating system with cloud native stack based on Kubernetes, will be very well architected for plug-and-play integration with its ecosystem as well.

KubeSphere provides a complete user experience around Kubernetes that incorporates a rich set of cloud native ecosystem tools, allows developers and DevOps teams use their favorite tools in a single front-end interface. KubeSphere delivers consolidated views while integrating a wide breadth of ecosystem tools upon Kubernetes and offer consistent user experience to reduce complexity. Most importantly, these functionalities are loosely coupled with the platform since they are pluggable and optional based on your demands, will not impact the flexibilty of Kubernetes.

Latest Release

KubeSphere 2.1.0 was released on November 12nd, 2019. Check the Release Notes For 2.1.0 for the updates.

Installation

KubeSphere can run anywhere from on-premise datacenter to any cloud to edge. In addition, it can be deployed on any Kubernetes distribution.

Attention: The following section is only used for minimal installation by default, see Complete Installation Guide for details.

Deploy on Existing Kubernetes

Prerequisites

• Kubernetes version: 1.13.0 ≤ K8s version < 1.16;
• Helm version: 2.10.0 ≤ Helm ＜ 3.0.0，(will support Helm v3 in KubeSphere v3.0) see Install and Configure Helm in Kubernetes;
• CPU > 1 Core，Memory > 2 G;
• An existing Storage Class in your Kubernetes clusters, use kubectl get sc to verify it.

Run the following command. When all Pods of KubeSphere are running, it means the installation is successsful. Then you can use http://<IP>:30880 to access the dashboard with default account admin/P@88w0rd.

$ kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-minimal.yaml
