[root@master opt]# kubectl cluster-info&&kubectl -n istio-system get all&&kubectl -n kubevirt get deployment
Kubernetes control plane is running at https://192.168.100.9:6443
CoreDNS is running at https://192.168.100.9:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
Warning: kubevirt.io/v1 VirtualMachineInstancePresets is now deprecated and will be removed in v2.

<p>Summary: <a href="https://en.wikipedia.org/wiki/The_Comedy_of_Errors">Wikipedia Summary</a>: The Comedy of Errors is one of <b>William Shakespeare's</b> early plays. It is his shortest and one of his most farcical comedies, with a major part of the humour coming from slapstick and mistaken identity, in addition to puns and word play.</p>
