Minimal KubeSphere on Kubernetes

We can deploy kubesphere on the existing Kubernetes cluster. In this demo, I'm going to use Minikube as my local Kubernetes cluster on windows. I've set up my minikube cluster on VirtualBox. So if you want to do same way on VirtualBox you can follow this link "Minikube installation on virtualbox" Once you are done with this you are good to go for further kubesphere installation on minikube

Step 1:
Start minikube cluster Command to start Minikube(docker desktop should be installed)

minikube start

Now you can start with the installation of kubesphere

Step 2:
Apply kubesphere-installer YAML file Use following command

kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yaml

Output:

Step 3:
Apply cluster configuration yaml file

kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml

Output

Step 4:
After KubeSphere is successfully installed, you can run the following command to view the installation logs:

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

Quick installation checks:
Use the following command to see all pods. You will see there are some newly created pods related to kubesphere.

kubectl get pod --all-namespaces

To check kubesphere service is running or not use following command to confirm

kubectl get svc/ks-console -n kubesphere-system

output

Connect with web UI

To connect with web UI check url given in output of logs command from step 4.

http://<ip>:30880

And enter Account: admin Password: P@88w0rd .

Once you are logged in , setup your own password

Done. Now you are into Kubesphere web ui.
