Aurora: Unknown schema in docker parameters

Question

I have an aurora file which contains this docker parameters:

jobs = [
  Service(cluster = 'mesos-fr',
      environment = 'devel',
      role = 'root',
      instances = 1,
      name = 'frontend_service',
      task = run_frontend_service,
      container=Docker(image='frontend_service', parameters=[{'name': 'frontend_service'}, {'publish': '{{thermos.ports[http]}}:3000'}])
  )
]

Got this error:

Error loading configuration: Unknown schema attribute publish

Is there a solution for connecting the host port with a docker container port?

Answer 1

EDIT: Mustache variable replacements might not help since they happen after the container comes up.

It looks like there's a problem with the form of your Docker Parameters. An example of correct ones is container=Docker(image='nginx', parameters=[Parameter(name='env', value='HTTP_PORT={{thermos.ports[http]}')]).

There is a Parameter object, with name and value. Value can be a string with mustache variable (like ports) so you can throw that stuff in there.

This documentation (under Announcer Objects) might help too: http://aurora.apache.org/documentation/latest/reference/configuration/
