Latest Release
KubeSphere 2.1.1 was released on February 23th, 2020. See the Release Notes For 2.1.1 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.xHelm version>=2.10.0，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:
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.
- 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.yaml
Deploy on Linux
