Azure AKS 생성하기

[root@workspace-vm ~]# az aks install-cli
Downloading client to "/usr/local/bin/kubectl" from "https://storage.googleapis.com/kubernetes-release/release/v1.14.1/bin/linux/amd64/kubectl"
Please ensure that /usr/local/bin is in your search PATH, so the `kubectl` command can be found.

[root@workspace-vm ~]# az aks get-credentials --resource-group aks-rg --name sanse-aks
Merged "sanse-aks" as current context in /root/.kube/config
