Rancher-metadata entry ordering (e.g. service containers)

I wonder in this request:

curl rancher-metadata/2015-12-19/self/stack/services/<someservice>/containers/

In which order the containers are returned.

Are they always strictly ordered by service_index?

As a side note: The extremely useful service_index attribute is not documented here: http://docs.rancher.com/rancher/rancher-services/metadata-service/

No, they are not ordered by service_index. The service_index just shows the last digit of the service name.

I will be adding it to the docs. Thanks for pointing it out!
