Stephan Erb commented on AURORA-1971:
-------------------------------------

What you are observing is the behaviour described here [https://github.com/apache/aurora/blob/master/docs/reference/configuration-templating.md#mustaches-within-structurals].  

You cannot see the name of the job as it is shadowed by the name of the process (see [https://github.com/wickman/pystachio#object-scopes] for details on scoping). A possible workaround could be to define a custom pystachio variable and use it in both places:
{code:java}
hello = Process(
  name='my_process_name',
  cmdline="""
    while true; do
      echo {{job_name}}
      sleep 10
    done
  """)

task = SequentialTask(
  processes=[hello],
  resources=Resources(cpu = 1.0, ram = 128*MB, disk = 128*MB))

jobs = [
   Service(
      task=task,
      cluster='devcluster',
      role = 'www-data',
      environment = 'prod',
      name = '{{job_name}}'
   ).bind(job_name='hello')
]
{code}

> I see there's a few different variables exposed in the pystachio configurations (environment, role, task.name, mesos), however I have not been able to figure out how to extract the job name. It seems a job's name defaults to task.name but in my case these are not the same. The use case for this is to simply export environment variables that give running processes access to their environment, role, and job names.
