simple IP lookup plugin

[Michael Ströder]

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.
