|
|
|
|
Exporting an autoscaling policy is similar to describing one, except that
|
|
export omits output only fields, such as the policy id and resource name. This
|
|
is to allow piping the output of export directly into import, which requires
|
|
that output only fields are omitted.
|
|
|
|
## EXAMPLES
|
|
|
|
The following command saves the contents of autoscaling policy
|
|
`example-autoscaling-policy` to a file so that it can be imported later:
|
|
|
|
$ {command} example-autoscaling-policy --destination=saved-policy.yaml
