How to Search for EC2 AMI ID by AWS Region with Ansible?

I’m going to show you a live demo and some simple Ansible code.

I’m Luca Berton and welcome to today’s episode of Ansible Pilot.

Ansible Search for EC2 AMI ID by AWS Region

amazon.aws.ec2_ami_info
Gather information about ec2 AMIs

Let’s talk about the Ansible module ec2_ami_info. The full name is amazon.aws.ec2_ami_info, which means that is part of the collection of modules to interact with AWS. The module’s purpose is to gather information about ec2 AMIs.

Parameters

filters dictionary - filter terms

Example:

name: "RHEL-8.3.0_HVM-*-x86_64-*Hourly*"
region: "us-east-1"

The following parameters are useful in order to Search for EC2 AMI ID by AWS Region using the module ec2_ami_info. The only parameter needed is the filters and specify the filters keys and values. For example, let’s search for Red Hat Enterprise Linux machines version 8.3.0 running on HVM infrastructure, architecture x86_64 Hourly paid.
