Feature:
NetworkManager now supports the AWS EC2 Instance Metadata Service Version 2 (IMDSv2), expanding its cloud setup capabilities.
Reason:
This development was driven by the increasing adoption of IMDSv2 due to improved security and compliance features that restrict unauthorized access to EC2 metadata. The integration between NetworkManager and IMDSv2 was necessary to meet the needs of AWS and Red Hat customers who rely on these advanced features.
Result:
The enhancement allows nm-cloud-setup to fetch and save IMDSv2 tokens, verify EC2 environments, and retrieve information about available interfaces and IP configurations by using the secured IMDSv2 tokens. This addition not only increases NetworkManager's compatibility with AWS services but also ensures a higher level of security for EC2 metadata. As a result, Red Hat customers can better meet their compliance requirements while maintaining efficient cloud setup processes.
