Tag propagation to launch templates - Amazon Elastic Beanstalk
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Tag propagation to launch templates

Elastic Beanstalk provides an option to enable the propagation of environment tags to launch templates. This option provides continued support for tag-based access control (TBAC) with launch templates.

Note

Launch configurations are being phased out and replaced by launch templates. For more information, see Launch configurations in the Amazon EC2 Auto Scaling User Guide.

To prevent down-time of running EC2 instances Amazon CloudFormation doesn’t propagate tags to existing launch templates. If there's a use case that requires tags for your environment’s resources, you can enable Elastic Beanstalk to create launch templates with tags for these resources. To do so, set the LaunchTemplateTagPropagationEnabled option in the aws:autoscaling:launchconfiguration namespace to true. The default value is false.

The following configuration file example enables the propagation of tags to launch templates.

option_settings:
  aws:autoscaling:launchconfiguration:
    LaunchTemplateTagPropagationEnabled: true

Elastic Beanstalk can only propagate tags to launch templates for the following resources:

  • EBS volumes

  • EC2 instances

  • EC2 network interfaces

  • Amazon CloudFormation launch templates that define a resource

This constraint exists because CloudFormation only allows tags on template creation for specific resources. For more information see TagSpecification in the Amazon CloudFormation User Guide.

Important

  • Changing this option value from false to true for an existing environment may be a breaking change for previously existing tags.

  • When this feature is enabled, the propagation of tags will require EC2 replacement, which can result in downtime. You can enable rolling updates to apply configuration changes in batches and prevent downtime during the update process. For more information, see Configuration changes.
