A new version of Anthos clusters on AWS (GKE on AWS) was released on April 6. See the release notes for more information.

Operating System details

Anthos clusters on AWS manages the AWS EC2 instances and the operating system running on these instances. Anthos clusters on AWS uses Minimal Ubuntu 18.04 LTS base images. Google tests these images as part of the Anthos clusters on AWS release process. When a management service, cluster, or node pool is upgraded, the underlying EC2 instances are terminated and recreated with the latest OS version.

The base Amazon Machine Image (AMI) is maintained by Canonical. When an instance launches, Anthos clusters on AWS performs additional configuration including:

  • Optimizing network settings for Kubernetes via sysctl
  • Installing packages from the Ubuntu archive
  • Disabling the Amazon SSM agent
  • Disabling unattended apt package upgrades and reboots
  • Installing Anthos and Kubernetes binaries

In the tables below, the Ubuntu AMI name is listed by release, followed by the AMI image ID by region.

Verifying AMI ownership

You can find the AMI ID for an AWS region in Ubuntu AMI IDs by region. To confirm that Canonical published these AMIs, verify that the OwnerID of the AMI has an OwnerID value of 099720109477.

To verify the OwnerID field, determine the AMI ID in the tables below then run:

aws ec2 describe-images --image-ids AMI_ID

Replace AMI_ID with the ID of the AMI in your AWS region.

For more information, see Amazon EC2 in the Ubuntu documentation.
