Hello,

I am new to ansible. Trying to understand a piece of ansible using debug.

- name: Evaluate oo\_all\_hosts  
add\_host:  
name: “{{ item }}”  
groups: oo\_all\_hosts  
ansible\_ssh\_user: “{{ g\_ssh\_user | default(omit) }}”  
ansible\_become: “{{ g\_sudo | default(omit) }}”  
with\_items: “{{ g\_all\_hosts | default() }}”  
changed\_when: no

I put a debug after this

- debug:  
var: oo\_all\_hosts

prints as undefined

no issues with g\_all\_hosts

Can someone help me identify the problem?

Thanks,  
SN

What happens if you add ‘register: blah’? So like this:

- name: Evaluate oo\_all\_hosts  
add\_host:  
name: “{{ item }}”  
groups: oo\_all\_hosts  
ansible\_ssh\_user: “{{ g\_ssh\_user | default(omit) }}”  
ansible\_become: “{{ g\_sudo | default(omit) }}”  
with\_items: “{{ g\_all\_hosts | default() }}”  
changed\_when: no

register: blah

The var in the debug module is expecting the variable to be previously registered with ‘register’.
