Configure NNM in a Docker Container

Before You Begin

Install an instance of NNM in a Docker container.

Dockerfile

FROM centos:7

EXPOSE 8835

ADD /nnm-5.0.0-es7.x86_64.rpm /nnm-5.0.0-es7.x86_64.rpm

RUN rpm -i nnm-5.0.0-es7.x86_64.rpm;

ENV PATH /opt/nnm/bin:$PATH

CMD /opt/nnm/bin/nnm && /opt/nnm/bin/nnm-proxy

Steps

  1. Copy the text of the Dockerfile section above and paste them in a file named Dockerfile.
  2. Copy the NNM *.rpm and paste it in the directory where you pasted the Dockerfile.

  3. In a Linux shell, run the cd command to navigate to the directory that contains Dockerfile and the NNM *.rpm and run the following command:

    docker build -t centos/nnm .

  4. Run the Docker container that contains NNM using the following command:

    docker run --net=host -d -p 8835:8835 centos/nnm

    Tip: If you need to interact with NNM from the shell, you can run the following command instead: docker run --net=host -t -i -p 8835:8835 centos/nnm

  5. Navigate to https://<IP address or hostname>:8835, which will display the NNM web front end to log in.

    Refer to the Configure NNM section of the NNM user guide for configuration instructions.

  6. In step 5 of the Configure NNM instructions, configure the monitored network interfaces depending on your needs, outlined in the Monitored Interfaces section of this guide.
