Supervisor is not starting up
I am following cloudera cdh4 installation guide.
My base file
FROM ubuntu:precise RUN apt-get update -y #RUN apt-get install -y curl RUN apt-get install -y software-properties-common python-software-properties RUN add-apt-repository ppa:webupd8team/java RUN apt-get update -y RUN echo debconf shared/accepted-oracle-license-v1-1 select true | \ debconf-set-selections RUN apt-get install -y oracle-java7-installer #Checking java version RUN java -version
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 http://archive.cloudera.com/cdh4/one-click-install/precise/amd64/cdh4-repository_1.0_all.deb > cdh4-repository_1.0_all.deb RUN dpkg -i cdh4-repository_1.0_all.deb RUN curl -s http://archive.cloudera.com/cdh4/ubuntu/precise/amd64/cdh/archive.key | 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
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
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.
