imageId

When configuring your HyperPod cluster, you can specify an image ID using one of the following options:

• HyperPodPublicAmiId: Use a HyperPod public AMI

• CustomAmiId: Use your custom AMI

• default: Use the default latest system image

If you choose to use a custom AMI (CustomAmiId), ensure it meets the following requirements:

• Encryption: The custom AMI must be unencrypted.

• Ownership: The custom AMI must be owned by the same Amazon Web Services account that is creating the HyperPod cluster.

• Volume support: Only the primary AMI snapshot volume is supported; additional AMI volumes are not supported.

When updating the instance group's AMI through the UpdateClusterSoftware operation, if an instance group uses a custom AMI, you must provide an ImageId or use the default as input. Note that if you don't specify an instance group in your UpdateClusterSoftware request, then all of the instance groups are patched with the specified image.
