Define the VM with the latest image of CentOS 7.6, Resource Group Py4SAS-vm, generate the ssh keys, and attach a 512GiB disk.

az vm create \
   --resource-group Py4SAS \
   --name Py4SAS-vm \
   --image OpenLogic:CentOS:7.6:latest \
   --size Standard_DS2_v2 \
   --generate-ssh-keys \
   --data-disk-sizes-gb 512 

Returns:

  "fqdns": "",
  "id": "/subscriptions/e452751c-5818-4258-993b-247904c15f97/resourceGroups/Py4SAS/providers/Microsoft.Compute/virtualMachines/Py4SAS-vm",
  "location": "eastus",
  "macAddress": "00-0D-3A-17-8C-AD",
  "powerState": "VM running",
  "privateIpAddress": "10.0.0.4",
  "publicIpAddress": "104.XXX.XX.XX",
  "resourceGroup": "Py4SAS",
  "zones": ""
}

Attach the disk to VM instance

az vm disk attach \
     --resource-group Py4SAS \
     --vm-name Py4SAS-vm \
     --name Py4SAS-disk \
     --size-gb 512 \
     --sku Premium_LRS \
     --new

ssh into the VM

ssh trb@104.XX.XX.XX

View file system before adding partition.

$ df -h

Use the bash command fdisk to partition the disk.

(echo n; echo p; echo 1; echo ; echo ; echo w) | sudo fdisk /dev/sdc

Write a file system to the partition.

sudo mkfs -t ext4 /dev/sdc1

Mount the disk.

sudo mkdir /opt && sudo mount /dev/sdc1 /opt

Verify the mountpoint is available.
