Docker Cloud grants you access to the logs your application writes to stdout.
An internal service multiplexes all the logs from all the containers of a
service into a single stream. To see a service's logs run the docker-cloud service logs command with the name of the service.
If you run docker-cloud service logs web, you see logs for both web-1 and
web-2, like the example below.
$ docker-cloud service logs web
