Can't get returned IPs from EC2

[Matthew Morgan]

So, I'm super stuck on this problem.  I created a pastie of all the info.

http://pastie.org/private/po3yakcngchu8wzjiwhsa

What am I doing wrong in the playbook that I can't get those IPs into my hosts file?  

Any help would be greatly appreciated!

add_host is for adding a host to current run's in-memory inventory, not the one on disk. It's used to provision a newly-created VMs.

You want to either use dynamic inventory and pull data from EC2, or somehow add the host to static inventory (with lineinfile maybe?)

Okay, I understand that it only adds to the in-memory inventory, but that's not really the problem I'm having.

The problem I'm having is I can't get the IP.  What I plan to do with the IP after I get it involves provisioning those hosts.  I can't provision those hosts unless I get the IP from the current run which creates the host.

The step where I should be able to get the IP to add it to a group (in memory or otherwise) is failing.

Sorry, I only skimmed that paste and missed the actual problem.
For the record: it's easier if you paste examples in your mail, and it's better for archiving too :-)

I think what you meant is "run this task for all of ec2.results", but what you wrote is "run this task for all of ['ec2.results']" (that's why it's complaining about a string).
You want:
      with_items: ec2.results

Dash at the beginning of a line creates a list element in YAML (that's why all tasks start with it :-))

That was exactly my issue.  Thank you very much for your help!
