MARATHON_APP_ID in log message

[michallula]

Hi, I wonder what is the best way to customize logs messages and to include additional information about Docker container from environment variables. I'm working on PaaS solution using Apache Mesos and Marathon. Marathon tasks launch Docker containers and set MARATHON_APP_ID variable which is human readable name of container. It can be retrieved with docker inspect command. I want to include this information in each log message. Is it possible with logspout?

Would be good being able to log some environment variables :)

The templating you have has access to the entire Docker container structure as far as I know. It should be possible.

We are already using this in Production cluster. We use the Logstash adapter, and have @modified it to access useful environment variables set in the docker container.

@michallula - Do you still have this issue ?
