I have a config file :

[ansible-master .ssh]# cat ~/.ssh/config  
Host \*  
StrictHostKeyChecking no

###### RAKA

Host node1  
Hostname 10.160.0.7  
IdentityFile ~/.ssh/RAKA  
Host node2  
Hostname 10.128.0.11  
IdentityFile ~/.ssh/RAKA  
Host node3  
Hostname 10.160.0.8  
IdentityFile ~/.ssh/RAKA  
[root@ansible-master .ssh]#

My Playbook is —

- hosts: localhost  
become: true  
become\_user: root

Configfile: ‘~/.ssh/config’  
ssh\_key\_location: ‘~/.ssh/“{{ SITEID }}”.pub’  
ssh\_key\_create\_path: ‘~/.ssh/“{{ SITEID }}”’  
vars\_prompt:
- name: “some\_password”

tasks:

- stat:

- name: Deploy teh Key generated on teh required machines  
shell: grep ‘Host’ “{{ SITEID }}” “{{ Configfile }}” |`awk '{print $2}'`

# raw: grep ‘Host’ “{{ SITEID }}” “{{ Configfile }}”

register: desired\_hosts

- debug:  
var: desired\_hosts.stdout\_lines  
command: ssh-copy-id -i “{{ ssh\_key\_location }}” “{{ desired\_hosts }}”

While running i am getting an error:

Hii

You seem to be running ansible as root (bad practice) yet also use become (not necessary), to generate SSH keys using a shell command and using the deploy user’s own ssh\_config as some sort of inventory.

The subject of the message says “Not getting desired o/p” - so what IS the desired output (assuming that’s what o/p means)?

Or perhaps a better question: what are you trying to achieve?

Dick

Hi Dick,  
Thanks for the reply . My target is i want to copy the pub key to all hosts present inside the ~/.ssh/config file(viz. node1,node2,node3).  
I had tried doing it using authorized\_key module , but as I dont want to make changes in the “ansibleconfig” for disabling the stict host checking. So i had to modify the playbook using shell module.  
But the shell module says that grep is not working. I think iam making something wrong in syntax…  
Would really appreciate , if any one can help me. achieving this goal.

Changing teh subject lien as you mentioned:)

Hi

The code you posted seems to generate a set of (unprotected) key pairs  
in the deploy user's home directory, and then tries to manually copy  
those hosts, using a mix of shell/grep/awk.  
And you want to copy "the pub key" to all hosts that are listed in the  
deploy user's ~/ssh/config.  
This is done using root locally, and also root on the remote hosts?  
It's still not clear to me what you want to achieve? I.e. the purpose  
of this playbook. Please explain more clearly.

In any case I would strongly advise to stop using root's ~/.ssh/config  
and instead use an inventory file:  
[https://docs.ansible.com/ansible/latest/user\_guide/intro\_inventory.html](https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html)

Also, if your purpose is to set up passwordless authentication to a  
number of hosts, then you should use the authorized\_key module.
