Run the installation script for an Azure virtual device

Create a virtual machine instance for each device in your system.

Download the Azure installation file from the Trellix download site. Each device's download section features an installation script for that device.
Create a temporary Linux VM to run the installer script.
Make sure you're familiar with Azure. You can find Microsoft Azure product information about the Microsoft Azure web site.

These instructions refer to third-party products. You might need to adapt to changes in interfaces or processes.

Tip

If you copy and paste commands, copying them to a text editor helps you get the spaces and line breaks correct.

Copy the installation file to the temporary VM:
```
scp <installation script file name> username@instance_ip_address:
```
Depending on network speed, it can take an hour or more to copy the file.
From the Azure dashboard, copy the public IP address of the server and connect to the server using scp or PuTTY.
Use the steps here to install the Azure CLI. Select the installation method for the Linux distribution you use, and in the section Install Azure CLI use Option 1 to install with one command. If this fails, use Option 2 to install step-by-step to understand what went wrong.
Log on to Azure. You can only log on if you successfully install the Azure CLI in Step 3.
1. At the command prompt, enter sudo az login
  You are prompted to authenticate.
```
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code <code> to authenticate.
```
2. Copy the authentication code.
3. Go to the URL and enter the authentication code.
This links the temporary VM to your Azure account so that when you run the installation script, the resulting device image is available in your Azure account.
Unzip the installation file.
Verify that the installation file was unzipped correctly:
```
sha256 -c <filename>
```
Run the installation script.
1. Change the permissions of the installation script:
```
Chmod 755 install*
```
2. Connect with super user rights:
```
sudo screen
```
  You are logged in as a root user.
3. Run the script. Use the -S option if you want to specify a disk size other than the default (500 GB).
```
./<installation script file name> -S <disk size in GB>
```
  You are prompted to browse to an authentication website and a unique authentication code is provided.
```
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code <code> to authenticate.
```
4. Enter the code provided and click Continue.
  A new image is created. This step takes about 20 minutes.
5. Note the value of the Group= message. You enter it later in the Resource Group field.
A new image appears in your Azure Resources group.
