## What is KubeSphere

> English | [中文](README_zh.md)

[KubeSphere](https://kubesphere.io/) is an enterprise-grade multi-tenant container management platform that built on [Kubernetes](https://kubernetes.io). It provides an easy-to-use UI for users to manage computing resources with a few clicks, which reduces the learning curve and empowers the DevOps teams. It greatly reduces the complexity of the daily work of development, testing, operation and maintenance, aiming to alleviate the pain points of Kubernetes' storage, network, security and ease of use, etc.

## Architecture

KubeSphere adopts the separation of front and back ends, each component is drawn in the architecture diagram below. KubeSphere can run anywhere from on-premise datacenter to any cloud to edge. In addition, it can be deployed on any Kubernetes distribution.

## Latest Release

KubeSphere 2.1.0 was released on **November 12nd, 2019**. See the [Release Notes For 2.1.0](https://kubesphere.io/docs/v2.1/zh-CN/release/release-v210/) to preview the updates.

## Installation

> Attention: Following section is only used for minimal installation by default, KubeSphere has decoupled some core components in v2.1.0, for more pluggable components installation, see `Enable Pluggable Components` below.

### Deploy On Kubernetes

**Prerequisites**

> - `Kubernetes version`： `1.13.0 ≤ K8s version < 1.16`;
> - `Helm version` >= `2.10.0`，see [Install and Configure Helm in Kubernetes](https://devopscube.com/install-configure-helm-kubernetes/);
> - CPU > 1 Core，Memory > 2 G;
> - An existing Storage Class in your Kubernetes clusters, use `kubectl get sc` to verify it.

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`.

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


### Deploy on Linux

- Operating Systems
   - CentOS 7.5 (64 bit)
   - Ubuntu 16.04/18.04 LTS (64 bit)
   - Red Hat Enterprise Linux Server 7.4 (64 bit)
   - Debian Stretch 9.5 (64 bit)
- Hardware
   - CPU：2 Core,  Memory：4 G, Disk Space：100 G

### All-in-One

For those who are new to KubeSphere and looking for the fastest way to install and experience the dashboard. Execute following commands to download and install KubeSphere in a single node.

```bash
$ curl -L https://kubesphere.io/download/stable/v2.1.0 > installer.tar.gz \
&& tar -zxf installer.tar.gz && cd kubesphere-all-v2.1.0/scripts
$ ./install.sh
```

Choose `"1) All-in-one"` to trigger the installation. Generally, you can install it directly without any configuration..

> Note: In a formal environment, it's highly recommended to install KubeSphere with Multi-Node Installation.

### Enable Pluggable Components

The above two methods is only used for minimal installation by default, execute following command to enable more pluggable components installation, make sure your cluster has enough CPU and memory in advance.

```
$ kubectl edit cm -n kubesphere-system ks-installer
```
