##### SUMMARY
This allows to use `module_defaults` against all the modules at once
using the new `hetzner.hcloud.all` `action_group`.
You can now pass the `api_token` argument using module_defaults:
```yaml
- name: Demonstrate the usage of the 'hetzner.hcloud.all' module_defaults group
hosts: localhost
connection: local
module_defaults:
group/hetzner.hcloud.all:
api_token: "{{ _vault_hcloud_api_token }}"
tasks:
- name: Create a volume
hetzner.hcloud.volume:
name: my-volume
location: fsn1
size: 100
state: present
register: volume
```
See the documentation and examples for more details.
