Troubleshoot EC2 Instances Using Ansible

Question

I am very confused about how you should run EC2 instances using Ansible.

I am trying to use ec2.py inventory scripts. I'm not sure which one is supposed to be used, because there are three installed with Ansible:

• ansible / Library / ansible / module_utils / ec2.py
• anzibl / Library / ansibl / modules / core / cloud / Amazon /ec2.py
• ansible / plugins / inventory / ec2.py

I thought running it in inventory / would make more sense, so I run it using:

ansible-playbook launch-ec2.yaml -i ec2.py

which gives me:

msg: Either region or ec2_url must be specified

So, I add the scope (even if I have vpc_subnet_id specified), and I get:

msg: Region us-east-1e does not seem to be available for aws module boto.ec2. If the region definitely exists, you may need to upgrade boto or extend with endpoints_path
