Host related problem

[skd...@126.com]

  Hello, 

        I just starte to use ansible, now there is a question ， when during the batch execution of the playbook, some operations are performed only on one of the hosts. How do you avoid other hosts on a piaybook while performing these operations?

  For example,：

                      I will perform batch execution operations on three hosts, A,B and C, and some of them will only be executed in A. How to do this

[Shankar Pentyala]

You can pick only one host as below example.

[webservers]

A

B

C

You can just pick host A by using 

hosts: groups[‘webservers’][0]

In your playbook.

Please check your loop properly. Possible the loop may have some logical issues.

Thanks & Regards,
