      Description

      While I was setting up a user example on connecting a remote IPython server,  I am stuck on this.

      Docker file

      FROM ubuntu
      RUN apt-get update
      RUN apt-get install python3 -y
      RUN apt install python3-pip -y
      RUN apt install net-tools
      RUN apt-get update && \
          DEBIAN_FRONTEND=noninteractive \
          apt-get -y install default-jre-headless && \
          apt-get clean && \
          rm -rf /var/lib/apt/lists/*
      
      # Fix certificate issues
      RUN apt-get update && \
          apt-get install ca-certificates-java && \
          apt-get clean && \
          update-ca-certificates -f;
      
      RUN export JAVA_HOME
      RUN pip3 install --no-cache-dir ipython
      RUN pip3 install --no-cache-dir jupyter-client
      RUN pip3 install --no-cache-dir protobuf
      RUN pip3 install --no-cache-dir grpcio
      
      # Setup JAVA_HOME -- useful for docker commandline
      ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
      

      As I attached the screenshots below, I set up my docker and Jenkins and try to run python code. It has got threw these exception.

        • Jenkins is running in my localhost:8080

      Question :

      It is working for the localhost( 127.0.0.1 ). Am I missing anything to connect to the docker container from Jenkins? (I could ping the docker container's IP successfully)

      Any help would be great. Thanks in advance
