Azure Load Generators

Private Locations on your Azure account

Azure Virtual Machines

Azure private locations require the control plane to have Azure credentials configured in order to instantiate virtual machines and associated resources.

Environment variables

Credentials can be set through environment variables in your control plane.

name value
AZURE_CLIENT_SECRET Client secret key

Check Azure documentation pages to find these values:
