How to create an AKS cluster

[rjshrjndrn]

Prerequisites

• you should have azure az cli installed. Either use azure cloud shell or refer this doc.

• Create one ssh keypair for access, and keep the public key for cluster clusrer creation.
  ssh-keygen -C deployer-kubernetes-key -f /tmp/deployer
  /tmp/deployer is your private key and /tmp/deployer.pem.pub is the public key.

Steps

# To create an SP
# az ad sp create-for-rbac --skip-assignment --name myAKSClusterServicePrincipal --role contributor

export SERVICE_PRINCIPAL=<azure sp id>
export CLIENT_SECRET=<azure sp password>
export VNET_SUBENET_ID=<azure vnet subnet id> # you can get this from the subnet properties.

# To get versions use `az aks get-versions --location centralindia`
az aks  create \
    --resource-group sunbird-devnew-env  \
    --name dev-k8s-1-19 \
    --node-count 2 \
    --admin-username deployer  \
    --kubernetes-version 1.19.3 \
    --service-principal ${SERVICE_PRINCIPAL} \
    --node-vm-size Standard_D4s_v3 \
    --client-secret ${CLIENT_SECRET} \
    --network-plugin azure \
    --ssh-key-value @deployer.pub  \
    --location centralindia \
    --vm-set-type VirtualMachineScaleSets \
    --vnet-subnet-id ${VNET_SUBENET_ID} \
    --enable-private-cluster
