Base Images

JARVICE supports most Ubuntu or CentOS-based images. There is currently no explicit support for other types such as Alpine.

For convenience, Nimbix provides various base images for both x86_64 and ppc64le platforms. Please note that these images are maintained as "best effort", and are meant mainly for convenience:

Ubuntu style


(Base Ubuntu image with remote access capabilities)


(Base Ubuntu image with Nimbix Desktop and remote access capabilities)


(nvidia/cuda-based image with remote access capabilities.)

CentOS style


(Base CentOS image with remote access capabilities)


(Base CentOS image with Nimbix Desktop and remote access capabilities)


(nvidia/cuda-based image with remote access capabilities.)


(CUDA-capable Ubuntu base image with remote access capabilities)


(CUDA-capable Ubuntu base image with remote access capabilities)

Specialty nimbix Base Images


(PowerAI base image for ML/DL and Distributed Deep Learning (DDL); this image is maintained in sync with IBM updates.)

Using 3rd party Base Images

It's possible to use virtually any Ubuntu or CentOS 3rd party base image, including those compatible with nvidia-docker (e.g. nvidia/cuda).

Nimbix provides simple, publicly accessible mechanisms to make these images "JARVICE-ready":

In both cases please see the for each repository for usage instructions. Note that not all functions are available on all platforms - currently the Nimbix Desktop is only available on x86_64.

The following example Dockerfile creates a JARVICE-ready image from a 3rd party base image:

FROM nvidia/cuda:8.0-cudnn5-devel-ubuntu14.04

RUN apt-get -y update && \
    apt-get -y install curl && \
    curl -H 'Cache-Control: no-cache' \ \
        | bash

# Expose port 22 for local JARVICE emulation in docker

For a more complete example involving a Jupyter Notebook, please see the Dockerfile for app-powerai-notebooks.

Container Engine Differences

JARVICE provides a high performance container engine used to deploy large scale applications. It does not use the Docker engine to run containers. Because of this, there are some subtle differences in operation:

  1. JARVICE containers run code as the user nimbix, not root. It's important when writing persistent data (in /data) that this not be done as root. Additionally, any USER directives in the Docker image are ignored once the container is run on JARVICE.
  2. EXPOSE directives are ignored - JARVICE forwards most ports into the container automatically. If you have problems with specific ports, please contact Support.
  3. ENTRYPOINT is ignored. JARVICE uses endpoints defined in the AppDef to run commands or start services inside the Docker image.

Best Practices

  1. Use wrapper scripts for commands to set environment variables, etc.
  2. Use sudo to gain privileges - the nimbix user supports passwordless sudo if the image is set up properly with image-common.
  3. Store persistent data in /data, but as user nimbix only. Data in this directory persists after your image exits, and the user may transfer files to and from this directory without having to run your application.
