What is a KubeSphere

KubeSphereIs in theKubernetesBuilt for cloud native applicationsDistributed operating system, fully open source, supports multi-cloud and multi-cluster management, provides full-stack IT automated operation and maintenance capabilities, and simplifies enterprise DevOps workflow. Its architecture makes it easy for third-party applications to integrate plug-and-play with cloud native ecosystem components.

As a full-stack multi-tenant container platform, KubeSphere provides an operation-friendly wizard interface to help enterprises quickly build a powerful and feature-rich container cloud platform. KubeSphere provides users with many of the capabilities needed to build an enterprise-level Kubernetes environment, for exampleMulti-cloud and multi-cluster management, Kubernetes resource management, DevOps, Application life cycle management, Micro-service governance (service grid), log query and collection, service and network, multi-tenant management, monitoring alarms, events and audit query, storage management, access control, GPU Support, network policy, mirror warehouse management, and security managementAnd so on.

KubeSphere is also open sourceKubekeyHelp enterprises quickly set up Kubernetes cluster in public cloud or data center with one click, provide single node, multi-node, cluster plug-in installation, and cluster upgrade and operation and maintenance.

Development and operation friendly

KubeSphere shields users from the complex technical details at the bottom of the infrastructure, helping enterprises seamlessly deploy, update, migrate, and manage existing containerized applications on top of various infrastructures. In this way, KubeSphere enables developers to focus on application development, enabling operations teams to speed up DevOps automation workflows and delivery processes with enterprise-class observability and troubleshooting mechanisms, unified monitoring and log query, storage and network management, and easy-to-use CI/CD pipelining.

Support to run KubeSphere on any platform

As a flexible, lightweight container PaaS platform, KubeSphere is very friendly to support different cloud ecosystems because it does not Hack into the native Kubernetes itself. In other words, KubeSphere can be deployed and run on any infrastructure and on all version-compatible Kubernetes clusters, including virtual machines, physical machines, data centers, public clouds, hybrid clouds, etc. You can choose to install KubeSphere on public clouds and hosted Kubernetes clusters (such as Ali Cloud, AWS, QingCloud, Tencent Cloud, Huawei Cloud, etc.), as well as import and manage existing Kubernetes clusters. KubeSphere can be deployed on the existing Kubernetes platform without modifying the user’s current resources or assets and without affecting their business. For more information, see Installing on Linux and Installing on Kubernetes.

Fully open source

With the open source model, the KubeSphere community drives development in an open manner. KubeSphere is 100% open source and free. It has been widely used in Docker and Kubernetes-centered development, testing and production environments, and a large number of services run smoothly on KubeSphere. You can find all the source code, documentation, and discussions on GitHub, and all the major open source project introductions can be found in the Open Source Project list.

Cloud native Landscape

KubeSphere is a member of CNCF Foundation and has passed Kubernetes consistency certification, which further enriches the CNCF cloud ecosystem.

Install kubesphere

GitHub provides two installation methods. We use the second one, but we need to install Helm. Helm is the Kubernetes package manager, which is the most convenient way to install K8S-related components.

Install the Helm

Each Helm release provides binary versions of various operating systems that can be manually downloaded and installed. Note that the installed version of helm is also related to Kubernetes, see Helm Version Support Policy for details.

1. Download the required version
2. Extract (Tar - ZXVF helm - v3.0.0 - Linux - amd64. Tar. Gz)
3. Locate the HELM program in the unzip directory and move it to the desired directory (mv linux-amd64/helm /usr/local/bin/helm)

2. Verify the installationhelm version

 kubectl taint nodes k8s-node1 node-role.kubernetes.io/master:NoSchedule-
Copy the code

# Add OpenEBS source
helm repo add openebs https://openebs.github.io/charts

# Update warehouse
helm repo update

Create the openEBS namespace
kubectl create ns openebs

# installation OpenEBS
helm install --namespace openebs --name openebs stable/openebs
Copy the code

Openebs-hostpath is used as the default StorageClass
kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
Copy the code

6. The LocalPV of OpenEBS has been created as the default storage type. Can be achieved bykubectl get scCommand to check whether the default label exists. And then by commandkubectl get pod -n openebsTo view the status of OpenEBS related PODS. If the STATUS of all pods is RUNNING, the storage device is successfully installed.

Install kubesphere

1. Run the following command to download the YML file to the local PC.

Kubectl apply -f kubectl at https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/kubesphere-installer.yaml Apply the -f https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/cluster-configuration.yamlCopy the code

2. Check installation logs

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
Copy the code

If this screen is displayed, the installation is successful



Use 3.kubectl get pods -ACheck to see if all pods are working properly in KubeSphere’s related namespace. If so, check the console port (default: 30880) by using the following command

kubectl get svc -n kubesphere-system
Copy the code

4. Log in to the console and check the node running status
