If you are only interested in the ip/hostname of the slave you are running on,
you should have a look at the `{{mesos.hostname}}` thermos variable. It will
resolve to whatever you passed into `--hostname` on the Mesos slave command
line. (details:
https://github.com/apache/aurora/blob/master/docs/configuration-reference.md#mesos-namespace)<https://github.com/apache/aurora/blob/master/docs/configuration-reference.md#mesos-namespace>
In general, there are various ways how you could expose environment variable to
your processes:
* copy your environment file into your sandbox: via wget or by doing a simple
"echo" process that pipes to a file in order to create it.
* source your environment file before launching your command: "source
environment && exec ./my-process"
* as a (undocumented) feature there is also `.thermos_profile`. If you create a
file in your sandbox named like this, it will automatically be sourced

?There is probably also a docker-specific mechanism. I don't know about docker,
but maybe someone can help here.
Hope this helps to get you started,

Subject: Source an environment file for jobs
Hi,
How does one source environment files for jobs submitted to slave?
Say for example, I want one of my containers to be aware of the
COREOS_PUBLIC_IPV4 variable stored in /etc/environment. I was wondering how
does one factor this while creating a .aurora. I use the docker Parameter
object with name 'env' and value should be 'public_ip=<source variable here>'.
I was thinking that I can copy the /etc/environment into the sandbox, however,
I do not know how to source them. Also, I have the specify this resource
dependency to thermos globally; is it possible to have the
thermos_executor_resources to be job specific?
Also, are there more .aurora file examples than the hello_world, hello_docker
and the few in documentation for reference?
Aurora + Mesos is awesome; enjoying playing around with it. Thanks!
