# Example that prints the loopback address and gateway for each host - debug: msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}
- debug: msg: System {{ inventory_hostname }} has gateway {{ ansible_default_ipv4.gateway }} when: ansible_default_ipv4.gateway is defined
# Example that prints return information from the previous task - shell: /usr/bin/uptime register: result
- debug: var: result verbosity: 2
- name: Display all variables/facts known for a host debug: var: hostvars[inventory_hostname] verbosity: 4
# Example that prints two lines of messages, but only if there is an environment value set - debug: msg: - "Provisioning based on YOUR_KEY which is: {{ lookup('env', 'YOUR_KEY') }}" - "These servers were built using the password of '{{ password_used }}'. Please retain this for later use."
msg: default: Hello world! description: - The customized message that is printed. If omitted, prints a generic message. type: str var: description: - A variable name to debug. - Mutually exclusive with the C(msg) option. - Be aware that this option already runs in Jinja2 context and has an implicit C({{ }}) wrapping, so you should not be using Jinja2 delimiters unless you are looking for double interpolation. type: str verbosity: default: 0 description: - A number that controls when the debug is run, if you set to 3 it will only run debug when -vvv or above type: int version_added: '2.1' version_added_collection: ansible.builtin
