KubeSphere 2.1.1 was released on February 23rd, 2020. See the Release Notes For 2.1.1 for the updates.
KubeSphere can run anywhere from on-premise datacenter to any cloud to edge. In addition, it can be deployed on any version-compatible running Kubernetes cluster.
Kubernetes version：1.15.x, 1.16.x, 1.17.x2.10.0 ≤ Helm Version ＜ 3.0.0excluding 2.16.0 because of #6894. Please see Install and Configure Helm in Kubernetes. Helm v3 will be supported in KubeSphere 3.0.0.- An existing Storage Class in your Kubernetes cluster, use
kubectl get scto verify it - The CSR signing feature is activated in kube-apiserver, see RKE installation issue.
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. You can enable other components after installation if more resource added in later on. See Pluggable Components Installation for detailed information.
kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-minimal.yaml- 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:
kubectl apply -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-complete-setup.yamlWait the installation logs using the following command till showing "Successful", then you can log in the console using the default username and password.
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -fKubeSphere Installer can help you to install KubeSphere and Kubernetes on your linux machines. It provides All-in-One and Multi-Node installation options.
