unable to fit the piece of code in ansible

[Bishwajit Samanta]

Hi all,

I am a beginner in ansible. If anyone can help me in finding the answer. It would be great. My problem was finding a phrase in ansible which one of the person have helped me. But unfortunately i am not able to fit the piece of code in my playbook.

hostinfo:

  host001':

    ip: 192.168.43.10

    hostclass: 'puppet'

  'host002':

    ip: 192.168.43.11

    hostclass: 'ess'

  'host003':

    ip: 192.168.43.21

    hostclass: 'mdb'

the code was::

- debug: 

  msg: "{{ hostinfo|dictsort|selectattr('1.hostclass', 'equalto', 'ess')|first|first }}"

Now i am writing the code as given below. I know in this piece of code i am making mistakes. But since i am a beginner i am not able to understand it. Can anyone help me?

- hosts: test

  gather_facts: no 

- debug: 

  msg: "{{ hostinfo|dictsort|selectattr('1.hostclass', 'equalto', 'ess')|first|first }}"

Any one can suggest any idea please..

Can I suggest that you describe what you want to achieve. That is, describe the end result that you are seeking.

That is more likely to get a useful response.

Regards, K.

Thanks Karl, for your reply. Problem statement ::-

My job is to find out the hostname which belongs to hostclass ess, which in this case the answer is host002.

hostinfo:
  'host001':
    ip: 192.168.43.10
    hostclass: 'puppet'
  'host002':
    ip: 192.168.43.11
    hostclass: 'ess'
  'host003':
    ip: 192.168.43.21
    hostclass: 'mdb'

i got one solution from some friend in google ansible groups only, but i am unable to fit it my ansible playbook.

- debug:
    msg: "{{ hostinfo|dictsort|selectattr('1.hostclass', 'equalto', 'ess')|first|first }}"

The playbook i am writing, which is wrong but i am not able to figure out how to fit the code in my playbook. Can anyone help me in modifying the code of mine.

- hosts: somehost
  gather_facts: no
  vars_files:
    file: sometext.yaml
    name: sometext

  - debug:
        msg: "{{ hostinfo|dictsort|selectattr('1.hostclass', 'equalto', 'ess')|first|first }}
