Ansible Command Module Argument Entry

[Carlton Patterson]

I'm trying to use Ansible's 'command' module to to issue the command 'hostname -s' on a machine. 

Can someone please take a look at the module and its arguments and let me know where I would enter the argument 'hostname -s'?

This runs your command on localhost:

---
# Test where vars are located
- hosts: localhost

  tasks:
    - name: run hostname command
      command: hostname -s

If you substitute the appropriate "hosts:" value , it will run it on another machine.

Regards, K.

Hi,

Why using command to have the hostname ? (command and shell module should be avoided each time it is possible) Fact already have some variable you can use, no ?

Example on my personnal machine :

       "ansible_fqdn": "DellJylenhof",
        "ansible_hostname": "DellJylenhof",
        "ansible_nodename": "DellJylenhof",

As I have not parameter domain on my machine, regarding documentation what you want is "ansible_hostname"

Regards,

JYL

While yes running hostname as a command seems redundant in this example (if you gather facts). If you do want to run a command anyway you want to put it in the free form box. The command/shell/script/raw are some of the only modules that use this form.
