Hello Fellow ansible users,

I am new to ansible, using version 1.7.2 on Mac OSx. I am trying to launch aws instances and install our code on them as part of an automated deployment process.
I am following this example http://docs.ansible.com/guide_aws.html

And my playbook is located here https://github.com/raj-andy1/macguffin/blob/master/aws-plays/aws-ec2.yaml

I need to launch the instance and add the instance name into my hosts file. however it is failing with this error -“One or more undefined variables: ‘item’ is undefined”
I have tried changing {{ item.public_dns_name }} to {{ instances.public_dns_name }} but no luck.

Can someone please help me out?

Thanks in advance for the help

The ec2 module is actually not returning this as an error, where you have it, there is no global named “item”.

This error message is appropriate.

You’ll need to debug a variable that’s actually in scope :slight_smile:

Can you post your playbook(s)?
