KubeSphere is also a multi-tenant enterprise-grade container platform with full-stack automated IT operation and streamlined DevOps workflows. It 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, see [Feature list](#features) for details. > Note: The [Screenshots](docs/en/guides/screenshots.md) give a close insight into KubeSphere, see [What is KubeSphere](https://kubesphere.io/docs/v2.1/en/introduction/what-is-kubesphere) for further information.

## Demo Environment Using the account `demo1 / Demo123` to log in the [demo environment](https://demo.kubesphere.io/). Please note the account is granted viewer access. You can also have a quick view of [KubeSphere Demo Video](https://youtu.be/u5lQvhi_Xlc). ## 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. ![](docs/images/architecture.png) ## Features |Feature|Description| |---|---| | Provisioning Kubernetes Cluster|Support deploy Kubernetes on your infrastructure out of box, including online and air gapped installation| | Kubernetes Resource Management | Provide web console for creating and managing Kubernetes resources, with powerful observability including monitoring, logging, events, alerting and notification | | DevOps System | Provide out-of-box CI/CD based on Jenkins, and offers automated workflow tools including binary-to-image (B2I) and source-to-image (S2I) | | Application Store | Provide application store for Helm-based applications, and offers application lifecycle management | | Service Mesh (Istio-based) | Provide fine-grained traffic management, observability and tracing for distributed microservice applications, provides visualization for traffic topology | | Rich Observability | Provide multi-dimensional monitoring metrics, and provides multi-tenant log query and collection, support alerting and notification for both application and infrastructure | | Multi-tenant Management | Provide unified authentication with fine-grained roles and three-tier authorization system, supports AD/LDAP authentication | | Infrastructure Management | Support node management and monitoring, and supports adding new nodes for Kubernetes cluster | | Storage Support | Support GlusterFS, CephRBD, NFS, Local (default) etc. open source storage solutions, provide CSI plugins to consume storage from cloud providers | | Network Support | Support Calico, Flannel, etc. open source network solutions, provides load balancer plug-in [Porter](https://github.com/kubesphere/porter) for Kubernetes installed on physical machines | | GPU Support | Support add GPU node, support vGPU, enables running ML applications on Kubernetes, e.g. TensorFlow | > Note: See this [Feature and Benefits](https://kubesphere.io/docs/v2.1/en/introduction/features/) for further information. ---- ## Latest Release KubeSphere 2.1.1 was released on **February 23th, 2020**. 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 version-compatible Kubernetes cluster. ### 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. **Minimum Requirements** - 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 > Note: Please disable the firewall, or ensure your firewall meets the [port requirements](https://kubesphere.io/docs/installation/port-firewall/). #### All-in-One (QuickStart) ```bash curl -L https://kubesphere.io/download/stable/latest > installer.tar.gz \ && tar -zxf installer.tar.gz && cd kubesphere-all-v2.1.1/scripts $ ./install.sh ``` Choose `"1) All-in-one"` to start the default minimal installation. You can enable other components after installation, see [Pluggable Components Installation](https://kubesphere.io/docs/v2.1/en/installation/pluggable-components/). ## To start using KubeSphere - KubeSphere Documentation ([En](https://kubesphere.io/docs/en/)/[中](https://kubesphere.io/docs/zh-CN/)） - [API Documentation](https://kubesphere.io/docs/v2.1/en/api-reference/api-docs/) ## To start developing KubeSphere The [development guide](https://github.com/kubesphere/community/tree/master/developer-guide/development) hosts all information about building KubeSphere from source, git workflow, how to contribute code and how to test. ## RoadMap Currently, KubeSphere has released the following 5 major editions. The future releases include multicluster, big data, AI, SDN, etc. See [Plans for 2.1.1 and 3.0.0](https://github.com/kubesphere/kubesphere/issues/1368) for more details. **Express Edition** => **v1.0.x** => **v2.0.x** => **v2.1.0** => **v2.1.1** => **v3.0.0** ![](https://pek3b.qingstor.com/kubesphere-docs/png/20190926000413.png) ## Landscapes
