Modify the instance metadata parameters on a running or stopped instance. When you modify the parameters on a stopped instance, they are applied when the instance is started. When you modify the parameters on a running instance, the API responds with a state of “pending”. After the parameter modifications are successfully applied to the instance, the state of the modifications changes from “pending” to “applied” in subsequent describe-instances API calls. For more information, see Instance metadata and user data in the Amazon EC2 User Guide.

)[required] The ID of the instance.
Indicates whether IMDSv2 is required.
optional - IMDSv2 is optional. You can choose whether to send a
session token in your instance metadata retrieval requests. If you
retrieve IAM role credentials without a session token, you receive
the IMDSv1 role credentials. If you retrieve IAM role credentials
using a valid session token, you receive the IMDSv2 role
credentials.
required - IMDSv2 is required. You must send a session token in
your instance metadata retrieval requests. With this option,
retrieving the IAM role credentials always returns IMDSv2
credentials; IMDSv1 credentials are not available.
Default:
If the value of ImdsSupport for the Amazon Machine Image (AMI) for
your instance is v2.0 and the account level default is set to
no-preference, the default is required.
If the value of ImdsSupport for the Amazon Machine Image (AMI) for
your instance is v2.0, but the account level default is set to
V1 or V2, the default is optional.
The default value can also be affected by other combinations of parameters. For more information, see Order of precedence for instance metadata options in the Amazon EC2 User Guide.
The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel. If no parameter is specified, the existing state is maintained.
Possible values: Integers from 1 to 64
Enables or disables the HTTP metadata endpoint on your instances. If this parameter is not specified, the existing state is maintained.
If you specify a value of disabled, you cannot access your instance
metadata.
Checks whether you have the required permissions for the action, without
actually making the request, and provides an error response. If you have
the required permissions, the error response is DryRunOperation.
Otherwise, it is UnauthorizedOperation.
Enables or disables the IPv6 endpoint for the instance metadata service. Applies only if you enabled the HTTP metadata endpoint.
Set to enabled to allow access to instance tags from the instance
metadata. Set to disabled to turn off access to instance tags from the
instance metadata. For more information, see Work with instance tags using the instance metadata.
