Create a Custom CUDA-capable Engine Image

The base engine image (docker.repository.cloudera.com/cdsw/engine:<version>) that ships with Cloudera Data Science Workbench will need to be extended with CUDA libraries to make it possible to use GPUs in jobs and sessions.

The following sample Dockerfile illustrates an engine on top of which machine learning frameworks such as Tensorflow and PyTorch can be used. This Dockerfile uses a deep learning library from NVIDIA called NVIDIA CUDA Deep Neural Network (cuDNN). For detailed information about compatibility between NVIDIA driver versions and CUDA, refer the cuDNN installation guide (prerequisites).

When creating the Dockerfile, you must delete the Cloudera repository that is inaccessible because of the paywall by running the following:

RUN rm /etc/apt/sources.list.d/*

Make sure you also check with the machine learning framework that you intend to use in order to know which version of cuDNN is needed. As an example, Tensorflow's NVIDIA hardware and software requirements for GPU support are listed in the Tensorflow documentation.

The following sample Dockerfile uses NVIDIA's official Dockerfiles for CUDA and cuDNN images.

docker build --network host -t <company-registry>/cdsw-cuda:10 . -f cuda.Dockerfile

Push this new engine image to a public Docker registry so that it can be made available for Cloudera Data Science Workbench workloads. For example:

docker push <company-registry>/cdsw-cuda:10
