Before creating an automation account, configure the corresponding parameters in the ARM template.

To configure the parameters, perform the following steps:

1. Download A10-vThunder_ADC-CONFIGURATION > CONFIG-SLB_ON_BACKEND-AUTOSCALE template from GitHub.

2. From Start menu, open PowerShell and navigate to this downloaded folder and open the CREATE_AUTOMATION_ACCOUNT_PARAM.json with a text editor.

   NOTE:

   Each parameter has a default value mentioned in the parameter file which can be modified as required.

3. Configure the following parameters:

4. Verify if all the configurations in the CREATE_AUTOMATION_ACCOUNT_PARAM.json file are correct and then save the changes.
   

5. Run the following command to create an automation account:

   PS C:\Users\TestUser\Templates> .\CREATE_AUTOMATION_ACCOUNT_1.ps1

To verify the creation of an automation account, perform the following steps:

1. From Home, navigate to Azure services > Resource Group ><resource_group_name>.
   The selected resource group - Overview window is displayed.
2. Under Resources tab, group the resources based on the resource type.
3. Verify if the recently created automation account is listed under Automation Accounts type.
   
4. Select the recently created automation account.
   The selected automation account - Overview window is displayed.

5. Click Variables from the left Shared Resources panel.
   The selected automation account - Variables window is displayed.

6. Verify if all the variables associated with the automation account are listed.

To change the Backend Autoscale vThunder instance password for the first-time, perform the following steps:

1. From Start menu, open PowerShell and navigate to A10-vThunder_ADC-CONFIGURATION > CONFIG-SLB_ON_BACKEND-AUTOSCALE template.

2. Run the following command to change the password:

   PS C:\Users\TestUser\Templates> .\CHANGE_PASSWORD_2.ps1

   NOTE:

   It is highly recommended to change the default password provided by the A10 Networks Support when you log in the vThunder instance for the first time.

3. Provide the default and new password when prompted:

   Enter New Password:*********
   Confirm New Password:*********

   The default password is provided by the A10 Networks Support. The new password should follow the Default password policy. For more information, see Default Password Policy.

4. Go to Azure services > Resource Group > <vmss_resource_group_name> > <automation_account> > Variables.

5. Verify if the timestamp in the Last modified column of the vThPassword variable is updated.

   Figure 183 : Updated Variables window

   

To change the Backend Autoscale vThunder password subsequently, perform the following steps:

1. Go to Azure services > Resource Group > <vmss_resource_group_name> > <automation_account> > Variables.
2. Update the password in the vThPassword variable manually and save the changes.
   The password gets encrypted.

To verify that the virtual machine instances are running, perform the following steps:

1. From Home, navigate to Azure services > Resource Group > <resource_group_name>.
   The selected resource group - Overview window is displayed.
2. Under Resources tab, group the resources based on the resource type.
3. Select the virtual machine scale set instance under Virtual machine scale set type and verify that the instance is in Start mode.
