Ansible and Dynamic Amazon EC2 Inventory Management

Error:

[root@ip-0.0.0.0]# /etc/ansible/ec2.py

region name: us-east-1b likely not supported, or AWS is down.  connection to region failed.

or

[root@ip-0.0.0.0]# /etc/ansible/ec2.py

region name: ap-south-1 likely not supported, or AWS is down.  connection to region failed.

Solution:

ec2.ini

Default value of 

regions = all

regions_exclude = us-gov-west-1,cn-north-1,ap-south-1,us-east-1b

One of regions not working which is us-east-1b so just add this in regions_exclude.

regions = all

regions_exclude = us-gov-west-1,cn-north-1,us-east-1b,ap-south-1

OR

regions = add-your-zone.

Run now.

[root@ip-host-name opt]# /etc/ansible/ec2.py
