Print Hostvar For All Host Under Group

[Jitender J]

Hi Team,

Need your help got stuck 

I want to use host vars from inventory for all host under a specific group

I tried with the below example but only getting IP when I am passing hostname not getting anything when trying to get ansbile_host variable value for all host under that group with the group name 

 ip: "{{hostvars['test']['ansible_host']}}"   ------Not working 

 ip: "{{hostvars['test1']['ansible_host']}}" -------- Working 

[test]

test1 ansible_host=1.1.1.1

test2 ansible_host=2.2.2.2

Hello,

This doesn't look like its a supported way, you can use index of one and access but not full group:

test2 ansible_host=2.2.2.2

[dev]
dev1 ansible_host=3.3.3.3
dev2 ansible_host=4.4.4.4
