Create a Kubernetes cluster on Azure
In this post we will use the CLI to create a Kubernetes Cluster on Azure (AKS). You can follow the video or continue reading.
Prerequisites
- Azure account
- Azure CLI installed and configured
- kubectl installed
Create a Kubernetes Cluster
The Azure resources we create are not free. Be sure to clean them up at the end! To create the cluster we have to create a resource group first. The following command creates a resource group named rg-cluster in the eastus region. Choose the region nearest to you.
az group create --name rg-cluster --location eastus
Now create the AKS cluster named aks-demo with one node in our new resource group
az aks create --resource-group rg-cluster --name aks-demo --node-count 1
After a few minutes, the command completes and returns JSON-formatted information about the cluster.
Connect to the cluster
First get the cluster credentials.
az aks get-credentials --resource-group rg-cluster --name aks-demo
This will update your Kubernetes configuration. Now we can connect to our cluster.
kubectl get nodes
NAME STATUS ROLES AGE VERSION
aks-nodepool1-33611276-vmss000000 Ready agent 12m v1.16.10
kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-544d979687-qq2mr 1/1 Running 0 16m
kube-system coredns-544d979687-rs2f4 1/1 Running 0 13m
kube-system coredns-autoscaler-98c475c7d-rv76g 1/1 Running 0 16m
kube-system dashboard-metrics-scraper-5f44bbb8b5-gxbxf 1/1 Running 0 16m
kube-system kube-proxy-xd2lc 1/1 Running 0 14m
kube-system kubernetes-dashboard-785654f667-74k8v 1/1 Running 0 16m
kube-system metrics-server-85c57978c6-5f8db 1/1 Running 0 16m
kube-system tunnelfront-57cdbb4775-47lmb 1/1 Running 0 16m
It works! The Kubernetes cluster is up and running.
Delete
To delete all resources created use:
az group delete --name rg-cluster
Summary
In this post we created a Kubernetes cluster on Azure.
