Hi

Can we run a playbook and have it prompt the user for the hostname to deploy the playbook tasks to?

This is what I have tried in my playbook.

I don’t know if this will help, but I never prompt for a host, and never define one in my playbooks with anything other than a variable:

I believe your problem is that you are specifying hosts twice. The following works for me (gather facts is enabled for this example (to check ansible_fqdn), but wouldn’t be necessary for this to work):

Hi

sorry for late response. Actually, I have found a way that works for me, and I hope can help others looking for the same thing. I found this solution elsewhere on the Internet as well. Basically, it seems hosts cannot take in a variable that is just defined, so the way around this is to have hosts reference a dynamic group, and then have the inputted hostname be added to the group via the add_hosts task

I am trying to pass 2 switch IP’s to get the available ports on both the switches. When I am trying to pass one switch IP, It is executing fine. When i am trying to pass 2 IP’s separating by split “SPACE” it is only executing on First switch IP.But not taking the second IP. Please see execution output and respective playbook
