Trying to use the stack name / service in a custom catalog.

The stack name is input from the catalog page.

io.rancher.scheduler.affinity:container\_label\_soft\_ne: io.rancher.stack\_service.name=${stack\_name}/${service\_name}

How do i go about pulling in the stack name and service into the yml files?

the `${stack_name}/${service_name}` are understood by Rancher when making scheduling decisions. You’ll need to escape them with a $ so, $${stack\_name}/$${service\_name}

If you want them from inside the container while running, then you just need to query metadata:

[http://rancher-metadata/2015-19-12/self/service/name](http://rancher-metadata/2015-19-12/self/service/name)  
[http://rancher-metadata/2015-19-12/self/stack/name](http://rancher-metadata/2015-19-12/self/stack/name)

from inside the container.
