["Stephan Erb (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AURORA-1805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15610949#comment-15610949 ] 

Stephan Erb commented on AURORA-1805:
-------------------------------------

FWIW, there is also the {{.thermos_profile}} file that can be used to inject env vars.

> The thermos DSL:
> {noformat}
> class Process(Struct):
>   cmdline = Required(String)
>   name    = Required(String)
>   # This is currently unused but reserved for future use by Thermos.
>   resources     = Resources
>   # optionals
>   max_failures  = Default(Integer, 1)      # maximum number of failed process runs
>                                            # before process is failed.
>   daemon        = Default(Boolean, False)
>   ephemeral     = Default(Boolean, False)
>   min_duration  = Default(Integer, 5)      # integer seconds
>   final         = Default(Boolean, False)  # if this process should be a finalizing process
>                                            # that should always be run after regular processes
>   logger        = Default(Logger, Empty)
> {noformat}
> If we can add a new field:
> {noformat}
> environment = Default(Map(String, String), {})
> {noformat}
> It will make it much easier to add environment variables.
> Right now the solution is to prefix environment variables to cmdline which can get janky and frustrating with the string interpolation.
