A version of Azure PowerShell CLI is bundled with Octopus Deploy. To determine the version of the bundled CLI, add the PowerShell below to an Azure PowerShell Script Step:
If you wish to use a different version, you can install the Azure PowerShell CLI on your Octopus Server, and configure Octopus to use the installed version instead.
To do this, create a variable named OctopusUseBundledAzureCLI and set its value to False.
With this value set, Octopus Deploy will not load the bundled Azure PowerShell CLI.
If you need to disable the Azure CLI altogether due to errors or the added time to login to the CLI, use OctopusDisableAzureCLI and set its value to True.
