Re: [ansible-project] How to Pick and match the inventory_hostname against {{ ansible_hostname }} using groups.hosts

[Brian Coca]

This is invalid, as i explained above:
when: inventory_hostname == groups.hosts"


This works when the 'current host' is also the 'first host in the
group', here [0] is an index on the list that is group.hosts, so it is
a valid comparison.

when: inventory_hostname == groups.hosts[0]

@Brian ,  Thanks a lot for your suggestion, this looks Great,

What about "when: inventory_hostname == groups.hosts"  when: 
inventory_hostname == groups.hosts[0] , i google around but did not get 
clear & explicit explanation about its usage

Re: [ansible-project] How to Pick and match the inventory_hostname against {{ ansible_hostname }} using groups.hosts

[Brian Coca]

First of all you are comparing a string (inventory_hostname) to a list
(groups.hosts, which is [host-test1, host-test2, noi-pranjala]).

if you want to match inventory-hostname to ansible_hostname, just do that:


when: inventory_hostname == ansible_hostname


that will skip the task when they don't match.


if you want the task to actually fail:


failed_when: inventory_hostname != ansiblie_hostname
