Dynamic inventory for Ansible Controller on Google Cloud and nodes on EC2 AWS

Question

I am trying to find out a way to create dynamic inventory in Ansible that can let me use the updated IP of EC2 instances after restart. I have tried to search in documentation but there is not much information available about it.

Any help around this will be appreciated.

Answer 1

This is how to update your inventory on EC2

https://docs.ansible.com/ansible/latest/user_guide/intro_dynamic_inventory.html#inventory-script-example-aws-ec2

For Google Cloud

Answer 2

After setting up the access key details in ec2.ini (an inventory script setting for ec2.py) , I was getting the error as "ERROR: "Forbidden", while: getting ElastiCache clusters" .

Solution: I intially thought that it is because of Google cloud but enabling the "elasticache = False" option in ec2.ini resolved the issue.

Answer 3

Usage of ec2.py script is deprecated and unmaintained. You have now to use the aws_ec2 inventory plugin.

Though this plugin only list ec2 instances (no more information on elasticache, rds...).
