Hello,

I have no idea how to solve an IP address problem. I need some tips. I have an inventory file with defined hosts:

[clab111]  
11.11.11.11

[clab222]  
22.22.22.22

Then I will start working on one host, for example:

The path to the subtitles PLAYBOOK\_NAME.yml and inv -limit “clab111”

In the meantime, I will use in the playbook\_name.yml, lineinfile module, which should replace any IP address to address of the clab111. I have all the regex, but I do not know how to set the variable that will contain the IP address from the file inventory file for that particular clab111. I tried with hostvars, but without success.

So I need:

- get IP address of (for example) clab111 from inventory file,
- define variable with this clabxxx\_ip: {{ my\_problem }}
- put here: sed -r ‘s/([0-9]{1,3}.){3}[1-9]{1,3}’/{{ clabxxx\_ip }}/g

Thanks for the patience. I spent a ton of time on the “google” solution but without success, it’s my first steps in ansible.

Your inventory doesn't say what you think it does.

[clab111] is a group, not a host, and it contains one host called '11.11.11.11',  
and so on.

Inventory docs are at: [http://docs.ansible.com/ansible/intro\_inventory.html](http://docs.ansible.com/ansible/intro_inventory.html) ,  
see if that makes it any clearer.
