Pass --ulimit nproc via Marathon

[Paul Bell]

Hi All,

"docker run" supports "docker run --ulimit nproc=N"

Is there a way to pass both "ulimit" and its "nproc=N" value via Marathon's POST /v2/apps API?

Thanks.

You should be able to pass it in the "parameters" subsection of the "container" section.

      "parameters" : [

        { "key" : "ulimit", "value" : "nproc=N" }

      ]

Can anyone provide some help with this?

Apparently, there's a long history of ulimit unpleasantness with Docker containers. It's ultimate solution appears to be via "docker run --ulimit nproc=N". But I need to be able to convey this via Marathon.

Thanks.

Hi Paul,

Aaron's reply upthread is correct - container.parameters gets passed all the way through to Docker.
