Kubernetes: Setting up a cluster on AKS

Most cloud providers provide a managed Kubernetes cluster at this point. Each time I come back to look at Kubernetes, I feel like I’ve forgotten something (or everything). This post is a cheat sheet for getting a cluster up and running on Azure (using AKS) with recommended extras.

Creating a Cluster

Getting ready

Firstly, let’s install the latest Azure CLI. Check here for the latest version. Run az --version to see what version you have if you have it installed already. Next, az login and az account set -s <subscriptionId> so that you’re ready to go.

Create the resource group: (location is important. some areas have no AKS support yet eg. australiasoutheast)

$ az group create --name myResourceGroup --location australiaeast

Create a Linux-only cluster

Create the AKS cluster:

$az aks create \
    --resource-group myResourceGroup \
    --name myAKSCluster \
    --node-count 1 \
    --enable-addons monitoring \
    --generate-ssh-keys

Connect kubectl to your cluster

Install latest kubectl using az aks install-cli. (You may need to update your path to find the correct kubectl.exe)

$ az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

Connect to the Kubernetes Dashboard:

$ az aks browse --resource-group myResourceGroup --name myAKSCluster

If you get permissions errors (due to RBAC), you can give cluster-admin permissions with:

$ kubectl create clusterrolebinding kubernetes-dashboard \
    -n kube-system --clusterrole=cluster-admin \
    --serviceaccount=kube-system:kubernetes-dashboard
