Docker – R creates multiple processes

I’m creating a docker container and I’m installing R in it.

The problem is, that when running R in the container, the main R process create ncores - 1 subprocesses.

  • Upgrade postgre sql 9.4.5 from 9.3.10 (Ubuntu 14.04.3 LTS) Dockerfile
  • Docker-Compose: Initialize vs Run
  • Graylog SMTP server without TLS/SSL
  • Unable to connect to an ibmnode:latest-based container with putty over ssh
  • 'nutc': unknown terminal type. docker
  • Communication between linked docker containers
  • So when running the docker on my laptop with 8 cores, I get 1 R process and 7 R subprocesses.

    I also tried to configure my Docker file similar to this:

    but is still not working.


    FROM ubuntu:14.04
    RUN sed -e 's/archive\.ubuntu/at\.archive\.ubuntu/g' -i /etc/apt/sources.list
    RUN apt-get update
    RUN apt-get -y install libatlas3-base
    RUN apt-get -y install libopenblas-base
    RUN apt-get -y install r-base
    RUN apt-get -y install r-base-dev
    RUN apt-get -y install apt-utils
    RUN echo "deb trusty/" >> /etc/apt/sources.list
    RUN gpg --keyserver --recv-key E084DAB9
    RUN gpg -a --export E084DAB9 | apt-key add -
    RUN apt-get update
    RUN apt-get -y --with-new-pkgs upgrade

    Did someone encountered this problem?

    I don’t know why, but the whole problem was caused by installing libopenblas-base.

    After removing the line

    RUN apt-get -y install libopenblas-base

    everything worked fine!

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
