amazon.aws.ec2_metadata_facts module – gathers facts (instance metadata) about remote hosts within EC2
Note
This module is part of the amazon.aws collection (version 3.5.0).
You might already have this collection installed if you are using the ansible package.
It is not included in ansible-core.
To check whether it is installed, run ansible-galaxy collection list.
To install it, use: ansible-galaxy collection install amazon.aws.
To use it in a playbook, specify: amazon.aws.ec2_metadata_facts.
New in amazon.aws 1.0.0
Synopsis
This module fetches data from the instance metadata endpoint in EC2 as per https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html.
The module must be called from within the EC2 instance itself.
The module is configured to utilize the session oriented Instance Metadata Service v2 (IMDSv2) https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html.
If the HttpEndpoint parameter https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyInstanceMetadataOptions.html#API_ModifyInstanceMetadataOptions_RequestParameters is set to disabled for the EC2 instance, the module will return an error while retrieving a session token.
Notes
Note
Parameters to filter on ec2_metadata_facts may be added later.
Examples
# Gather EC2 metadata facts
- amazon.aws.ec2_metadata_facts:
- debug:
msg: "This instance is a t1.micro"
when: ansible_ec2_instance_type == "t1.micro"
Returned Facts
Facts returned by this module are added/updated in the hostvars host facts and can be referenced by name just like any other host fact. They do not need to be registered in order to use them.
