Supervisor is not starting up

I am following cloudera cdh4 installation guide.

    My hadoop installation file

    java_ubuntu is the image build from my base file.

    FROM java_ubuntu:latest
    RUN apt-get update -y
    RUN apt-get install -y curl
    RUN curl > cdh4-repository_1.0_all.deb
    RUN dpkg -i cdh4-repository_1.0_all.deb
    RUN curl -s | apt-key add -
    RUN apt-get update -y
    RUN apt-get install -y hadoop-0.20-conf-pseudo
    #Check for /etc/hadoop/conf.pseudo.mrl to verfiy hadoop packages
    RUN echo "dhis"  
    RUN dpkg -L hadoop-0.20-conf-pseudo

    Supervisor part
    hadoop_ubuntu is the image build from my hadoop installation docker file

    FROM hadoop_ubuntu:latest
    USER hdfs
    RUN hdfs namenode -format
    USER root
    RUN apt-get install -y supervisor
    RUN echo "[supervisord] nodameon=true  [program=namenode] command=/etc/init.d/hadoop-hdfs-namenode -D" > /etc/supervisorconf.d
    CMD ["/usr/bin/supervisord"]

    Program is successfully build. But namenode is not starting up? How to use supervisor?

    You have your config in /etc/supervisorconf.d and I don’t believe that’s the right location.

    It should be /etc/supervisor/conf.d/supervisord.conf instead.

    Also it’s easier to maintain if you make a file locally and then use the COPY instruction to put it in the image.

    Then as someone mentioned you can connect to the container after it’s running (docker exec -it <container id> /bin/bash) and then run supervisorctl to see what’s running and what might be wrong.

    Perhaps you need line breaks in your supervisor.conf. Try hand crafting one and COPY it into your dockerfile for testing.

    Docker and supervisord

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