Auto Scaling
API Reference (API Version 2011-01-01)


Creates or updates tags for the specified Auto Scaling group.

A tag is defined by its resource ID, resource type, key, value, and propagate flag. The value and the propagate flag are optional parameters. The only supported resource type is auto-scaling-group, and the resource ID must be the name of the group. The PropagateAtLaunch flag determines whether the tag is added to instances launched in the group. Valid values are true or false.

When you specify a tag with a key that already exists, the operation overwrites the previous tag definition, and you do not get an error message.

For more information, see Tagging Auto Scaling Groups and Instances in the Auto Scaling Developer Guide.
