Create a Linux virtual machine with the Azure CLI

The Azure CLI is used to create and manage Azure resources from the command line or in scripts. This guide details using the Azure CLI to deploy a virtual machine running Ubuntu 16.04 LTS. Once the server is deployed, we will use SSH to connect to VM in order to install NGINX.

If you don't have an Azure subscription, create a free account before you begin.

Also, make sure that the Azure CLI has been installed. For more information, see Azure CLI installation guide.

Log in to Azure

Log in to your Azure subscription with the az login command and follow the on-screen directions.

az login

Create a resource group

Create a resource group with the az group create 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 westeurope location.

az group create --name myResourceGroup --location westeurope

Create virtual machine

Create a VM with the az vm create command.

The following example creates a VM named myVM and creates SSH keys if they do not already exist in a default key location. To use a specific set of keys, use the --ssh-key-value option.

az vm create --resource-group myResourceGroup --name myVM --image UbuntuLTS --generate-ssh-keys

When the VM has been created, the Azure CLI shows information similar to the following example. Take note of the publicIpAddress. This address is used to access the VM.

{
  "fqdns": "",
  "id": "/subscriptions/d5b9d4b7-6fc1-0000-0000-000000000000/resourceGroups/myResourceGroup/providers/Microsoft.Compute/virtualMachines/myVM",
  "location": "westeurope",
  "macAddress": "00-0D-3A-23-9A-49",
  "powerState": "VM running",
  "privateIpAddress": "10.0.0.4",
  "publicIpAddress": "40.68.254.142",
  "resourceGroup": "myResourceGroup"
}

Open port 80 for web traffic

By default only SSH connections are allowed into Linux virtual machines deployed in Azure. If this VM is going to be a webserver, you need to open port 80 from the Internet. A single command is required to open the desired port.

az vm open-port --port 80 --resource-group myResourceGroup --name myVM

SSH into your VM

Use the following command to create an SSH session with the virtual machine. Make sure to replace <publicIpAddress> with the correct public IP address of your virtual machine. In our example above our IP address was 40.68.254.142.

ssh <publicIpAddress>

Install NGINX

Use the following bash script to update package sources and install the latest NGINX package.

#!/bin/bash

# update package source
apt-get -y update

# install NGINX
apt-get -y install nginx

View the NGIX welcome page

With NGINX installed and port 80 now open on your VM from the Internet - you can use a web browser of your choice to view the default NGINX welcome page. Be sure to use the publicIpAddress you documented above to visit the default page.

NGINX default site

Delete virtual machine

When no longer needed, the following command can be used to remove the Resource Group, VM, and all related resources.

az group delete --name myResourceGroup
