propagateAtLaunch

Enables propagation of the tag to Amazon EC2 instances launched via this ASG To declare multiple tags additional tag blocks can be specified. Alternatively the tags attributes can be used, which accepts a list of maps containing the above field names as keys and their respective values. This allows the construction of dynamic lists of tags which is not possible using the single tag attribute. tag and tags are mutually exclusive, only one of them can be specified.

NOTE: Other AWS APIs may automatically add special tags to their associated Auto Scaling Group for management purposes, such as ECS Capacity Providers adding the AmazonECSManaged tag. These generally should be included in the configuration so the provider does not attempt to remove them and so if the min_size was greater than zero on creation, that these tag(s) are applied to any initial EC2 Instances in the Auto Scaling Group. If these tag(s) were missing in the Auto Scaling Group configuration on creation, affected EC2 Instances missing the tags may require manual intervention of adding the tags to ensure they work properly with the other AWS service.
