I need a help about a problem about creation groups. I created a playbook AWS in which I create the instances and I have a file called host. My objective is when AWS creates the instances I want, separate the IPs for groups example below. I don’t know how I will to do in this subject.

Example

[GroupA]

Ip Ansible-01

[Group B]

Ip Ansible-02

Ip Ansible-03

Thanks in advance

Best Regards

I’m not sure about separating into groups by IP, but would you be able to use the [amazon.aws.aws\_ec2](https://docs.ansible.com/ansible/latest/collections/amazon/aws/aws_ec2_inventory.html#ansible-collections-amazon-aws-aws-ec2-inventory) inventory plugin to make keyed\_groups by some value? There are several examples of keyed\_groups in the documentation that may help you.

Hello Dedeboy,  
what you can do is to add a tag to each machine with the ip of the machine, and then in the aws dynamic inventory that you use in kayed\_groups, take the tag value and it will form groups by ip.  
In the dynamic inventory you could put something like this:  
kayes\_groups:  
key: ip\_  
tag  
and this will take the tag from each machine’s own variable, creating groups by its IP.
