 ** instanceMetadataTagsPropagation **   <a name="ECS-Type-InstanceLaunchTemplateUpdate-instanceMetadataTagsPropagation"></a>
Determines whether tags are propagated to the instance metadata service (IMDS) for Amazon EC2 instances launched by the Managed Instances capacity provider. When enabled, all tags associated with the instance are available through the instance metadata service. When disabled, tags are not propagated to IMDS.  
Disable this setting if your tags contain characters that are not compatible with IMDS, such as `/`. IMDS requires tag keys to match the pattern `[0-9a-zA-Z\-_+=,.@:]{1,255}`.  
The default value is `true`.  
For more information, see [Work with instance tags in instance metadata](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html#work-with-tags-in-IMDS) in the *Amazon EC2 User Guide*.
