How can I use the ip in a playbook when inventory has ansible_host

[Scott Fella]

Currently trying to see if there is a way I can grab the ip defined in the ansible_host and use that in a playbook.  I know there is inventory_hostaname, but these for example are not in dns.

hosts inventory example:

[aireos]
wlc2504-01 ansible_host=10.10.201.24

wlc2504-02 ansible_host=10.10.201.25

wlc5520-01 ansible_host=10.11.201.24

wlc5520-02 ansible_host=10.11.201.25

Here is a sample of a playbook which works if the device is registered in dns but fails of course when not.  Is there any way I can extract the ip address so I can loop through all devices in the inventory group?

- name: Check if SNMPv2 is working on remote host

hosts: aireos

connection: local

gather_facts: no

tasks:

- name: Test SNMPv2

local_action: command snmpget -v 2c -c testSNMPxxx {{inventory_hostname}} 1.3.6.1.2.1.1.5.0

register: response

- name: Print the complete response

debug:

var: response

Thanks,

Thank you very much!  I can't believe that I didn't scroll down that page far enough, basically was looking at the magic variables.

Hello Scott,

in fact ansible_host is a special variable, but any variable you stick on the host line will be available as
variable later.

[aireos]
wlc2504-01 ansible_host=10.10.201.24 myvar=foo

Can be used as {{ myvar }}.

Racke

Thanks for that info also. I will play around with that in the inventory or in the host_vars. That gives me more options I can use during a play.
