Ansible - Debug module

Ad hoc

With the ansible command line

Example to get the ansible_host value

ansible -i inventory.yml -m debug -a var=ansible_host all
# or an expression
ansible -m debug -a "msg={{ ansible_host.split('.', 1)[0] }}" all

where:

• ansible command line
• inventory is an inventory file
• -m set the module to debug
• -a set the argument (ie var=ansible_host)
• all means on all target (machine)

Output:

vps | SUCCESS => {
    "ansible_host": "server01.example.com"
}
