## What is KubeSphere
|
||
|
||
> English | [中文](README_zh.md)
|
||
|
||
[KubeSphere](https://kubesphere.io/) is a multi-tenant enterprise-grade container platform built on [Kubernetes](http://kubernetes.io), with full-stack automated IT operation and streamlined DevOps workflows. KubeSphere provides developer-friendly wizard web UI, helping enterprises to build out a more robust and feature-rich platform, which 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, more security enhancements** in upcoming releases. KubeSphere is a **distributed operating system with cloud native stack** with Kubernetes as its kernel, and will be very well architected for **plug-and-play integration for third-party applications to boost its ecosystem**.
|
||
|
||
KubeSphere provides a complete user experience around Kubernetes that incorporates a set of cloud native ecosystem tools, allowing developers and DevOps teams use their favorite tools in a unified console. KubeSphere delivers **consolidated views while integrating a wide breadth of ecosystem tools** around Kubernetes and offers consistent user experience to reduce complexity. Most importantly, these functionalities are loosely coupled with the platform since they are pluggable and optional at your will. Last but not least, it does not change Kubernetes itself anything. In another word, KubeSphere can be deployed on any existing version-compatible Kubernetes cluster.

|
||
## Architecture
|
||
|
||
KubeSphere uses a loosely-coupled architecture that separates the [frontend](https://github.com/kubesphere/console) from the [backend](https://github.com/kubesphere/kubesphere), the back end can also be connected with external systems through the REST API, all components are designed as Docker containers. See [Architecture](https://kubesphere.io/docs/v2.1/en/introduction/architecture/) for details.
|
||
|
||
|
||
## Latest Release
|
||
|
||
KubeSphere 2.1.1 was released on **February 23th, 2019**. See the [Release Notes For 2.1.1](https://kubesphere.io/docs/v2.1/en/release/release-v211/) 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.
|
||
|
||
### Deploy on Existing Kubernetes
|
||
|
||
**Prerequisites**
|
||
|
||
> - `Kubernetes version`： `1.15.x, 1.16.x, 1.17.x`
|
||
> - `Helm version` >= `2.10.0`，see [Install and Configure Helm in Kubernetes](https://devopscube.com/install-configure-helm-kubernetes/), (Helm v3 will be supported in KubeSphere 3.0.0)
|
||
> - An existing Storage Class in your Kubernetes cluster, use `kubectl get sc` to verify it
|
||
> - The CSR signing feature is activated in kube-apiserver, see [RKE installation issue](https://github.com/kubesphere/kubesphere/issues/1925#issuecomment-591698309).
|
||
|
||
Install KubeSphere using kubectl.
|
||
|
||
- If there are 1 Core and 2 GB RAM available in your cluster, use the command below to set up a default minimal installation only:
|
||
|
||
```bash
|
||
kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-minimal.yaml
|
||
```
|
||
|
||
You can enable other components after installation, see [Pluggable components Installation](https://kubesphere.io/docs/v2.1/en/installation/pluggable-components/).
|
||
|
||
- If there are 8 Cores and 16 GB RAM available in your cluster, use the command below to install a complete KubeSphere, i.e. with all components enabled:
|
||
|
||
```bash
|
||
kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-complete-setup.yaml
|
||
```
|
||
|
||
### Deploy on Linux
|
||
|
||
KubeSphere Installer can help you to install KubeSphere and Kubernetes on your linux machines. It provides [All-in-One](https://kubesphere.io/docs/v2.1/en/installation/all-in-one/) and [Multi-Node](https://kubesphere.io/docs/v2.1/en/installation/multi-node/) installation options.
