HI!

Is there a simple example module how to implement an ansible (connection) plugin for looking up an IP address for establishing the SSH connection?

I have a deployment where no DNS entries are present prior to initial host configuration, but I can access another (LDAP) database to query the IP address by inventory\_hostname.

Not sure whether I need a full-blown connection plugin [1] for this.

Ciao, Michael.

It probably easier to create[1] you own inventory plugin[2] so you can populate the ansible\_host with the IP.

Yes, you're right. I have this working now after I figured out to set  
'inventory\_plugins' in ansible.cfg and some other details.

Thank you.

Ciao, Michael.
