Background
The currently used AMI of Ubuntu 20.04 will no longer be a part of standard Ubuntu security maintenance by May 2025. We therefore are updating the default AMI used by c4 for native AWS deployments to 24.04.
Improvement
The default AWS AMI for AWS native deployments has been updated to Ubuntu 24.04.
Changed behavior
- IMDS v1 is now explicitly set for all new AWS native deployments that are created by c4. - The "c4 update cluster" command will now create a "LaunchTemplate" resource during the template update. This launch template resource is used to force IMDS v1 for all newly added nodes (e.g. added as a part of worker cluster creation).
