Deploy the Azure Resource Manager template

Create a resource group

Azure Resource Manager templates deploy resources into a resource group. Create a new resource group to contain your Cobalt 100 VM and its associated resources:

    

        
        
az group create --name cobalt-rg --location eastus

    

Replace eastus with your preferred Azure region. To see available regions that support Cobalt 100 VMs, query Azure for VM SKUs and filter for the Dpsv6 series:

    

        
        
az vm list-skus --location eastus --size Standard_D --all --output table | grep "ps_v6"

    

The output is similar to:

    

        
        virtualMachines  eastus       Standard_D16ps_v6       2,3      None
virtualMachines  eastus       Standard_D2ps_v6        2,3      None
virtualMachines  eastus       Standard_D32ps_v6       2,3      None
virtualMachines  eastus       Standard_D48ps_v6       2,3      None
virtualMachines  eastus       Standard_D4ps_v6        2,3      None
virtualMachines  eastus       Standard_D64ps_v6       2,3      None
virtualMachines  eastus       Standard_D8ps_v6        2,3      None
virtualMachines  eastus       Standard_D96ps_v6       2,3      None

        
    

Prepare template parameters

The template requires several parameters for deployment. You can provide these values interactively or use a parameters file.

First, read your SSH public key:

    

        
        
cat ~/.ssh/azure_cobalt_key.pub

    

Copy the output, which you’ll use as the adminPublicKey parameter.

Deploy with Azure CLI (interactive)

Deploy the template using the Azure CLI. The command prompts you to enter parameter values:

    

        
        
az deployment group create \
  --resource-group cobalt-rg \
  --template-file cobalt-vm-template.json \
  --parameters projectName=cobaltdemo \
               adminUsername=azureuser \
               adminPublicKey="<your-ssh-public-key>"

    

Replace <your-ssh-public-key> with the output from the cat command above.

The deployment takes approximately two to three minutes. Azure CLI displays progress and shows you when the deployment completes.

Deploy with a parameters file (optional)

For repeated deployments or automation, create a parameters file named cobalt-vm-parameters.json:

    

        
        
{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "projectName": {
      "value": "cobaltdemo"
    },
    "adminUsername": {
      "value": "azureuser"
    },
    "adminPublicKey": {
      "value": "ssh-rsa AAAAB3NzaC1yc2EAAAA... your-email@example.com"
    },
    "vmSize": {
      "value": "Standard_D4ps_v6"
    }
  }
}

    

Replace the adminPublicKey value with your actual SSH public key.

Deploy using the parameters file:

    

        
        
az deployment group create \
  --resource-group cobalt-rg \
  --template-file cobalt-vm-template.json \
  --parameters @cobalt-vm-parameters.json

    

Verify the deployment

Check the deployment status:

    

        
        
az deployment group show \
  --resource-group cobalt-rg \
  --name cobalt-vm-template \
  --query properties.provisioningState

    

The output displays "Succeeded" when the deployment completes.

List the resources created in the resource group:

    

        
        
az resource list --resource-group cobalt-rg --output table

    

The output is similar to:

    

        
        Name                                                     ResourceGroup    Location    Type                                     Status

The output shows the resources created: virtual machine, network interface, public IP address resource, virtual network, network security groups, and OS disk.

Retrieve the Cobalt 100 VM public IP address

Get the public IP address to connect to your VM:

    

        
        
az vm show \
  --resource-group cobalt-rg \
  --name cobaltdemo-vm \
  --show-details \
  --query publicIps \
  --output tsv

    

Save this IP address, because you’ll use it to connect via SSH.

What you’ve accomplished and what’s next

You’ve deployed an Arm-based Cobalt 100 VM using an Azure Resource Manager template. The deployment includes network infrastructure with security groups, a public IP address, and a VM running Ubuntu 24.04 LTS.

Next, you’ll connect to your VM and verify the Arm64 architecture.
