 Before deploying, you need to create a resource group with the [az group create](/cli/azure/group) command. An Azure resource group is a logical container into which Azure resources are deployed and managed. The following example creates a resource group named *myResourceGroup* in the *eastus* location.
 
 ```azurecli-interactive 
-az group create --name myResourceGroup --location eastus
+az group create --name myCentOSGroup --location eastus
 ```
 
 Now, create a VM with [az vm create](/cli/azure/vm) and specify the cloud-init file with the `--custom-data` parameter as follows:
 
 ```azurecli-interactive 
 az vm create \
-  --resource-group myResourceGroup \
-  --name centos74 \
-  --image OpenLogic:CentOS:7.5:latest \
+  --resource-group myCentOSGroup \
+  --name centos83 \
+  --image OpenLogic:CentOS:8_3:latest \
   --custom-data cloud_init_upgrade.txt \
+  --admin-username azureuser \
   --generate-ssh-keys 
 ```
 
 SSH to the public IP address of your VM shown in the output from the preceding command. Enter your own **publicIpAddress** as follows:
 
 ```bash
-ssh <publicIpAddress>
+ssh azureuser@<publicIpAddress>
 ```
 
 Run the package management tool and check for updates.
