Storage Variables

Tip

All storage roles have the ability to generate host_vars templates when the generate_host_vars tag is used. This allows you to run the playbooks to generate the necessary variables before actually provisioning storage. For example, you can run the following command to generate host variables for all Azure Windows hosts provisioned with managed disks:

ansible-playbook -i inventory.azure_rm.yml --limit='has_attached_disks:&azure_rm_windows' playbooks/storage/provision-azure-windows.yml --tags generate_host_vars

Storage variables are typically defined in host_vars because they are usually specific to individual hosts, however, variables may be defined in group_vars if they apply to a group of hosts. The storage variable structure is different for Windows and Linux. See below for examples.
