GPU-Jupyter

Leverage Jupyter Notebooks with the power of your NVIDIA GPU and perform GPU calculations using Tensorflow and Pytorch in collaborative notebooks.

First of all, thanks to docker-stacks for creating and maintaining a robost Python, R and Julia toolstack for Data Analytics/Science applications. This project uses the NVIDIA CUDA image as the base image and installs their toolstack on top of it to enable GPU calculations in the Jupyter notebooks. The image of this repository is available on Dockerhub.

Requirements

1. A NVIDIA GPU
2. Install Docker version 1.10.0+ and Docker Compose version 1.6.0+.
3. Get access to your GPU via CUDA drivers within Docker containers. Therfore, check out this medium article. The CUDA toolkit is not required on the host system, as it will be deployed in NVIDIA-docker. You can be sure that you can access your GPU within Docker, if the command docker run --gpus all nvidia/cuda:10.1-base-ubuntu18.04 nvidia-smi returns a result similar to this one:

4. Clone the Repository or pull the image from Dockerhub:

   git clone https://github.com/iot-salzburg/gpu-jupyter.git
   cd gpu-jupyter

Quickstart

First of all, it is necessary to generate the Dockerfile based on the NIVIDA base image and the docker-stacks. As soon as you have access to your GPU within Docker containers (make sure the command docker run --gpus all nvidia/cuda:10.1-base-ubuntu18.04 nvidia-smi shows your GPU statistics), you can generate a Dockerfile, build and run it. The following commands will start GPU-Jupyter on localhost:8848 with the default password asdf.

./generate_Dockerfile.sh
docker build -t gpu-jupyter .build/  # will take a while
docker run -d -p [port]:8888 gpu-jupyter  # starts gpu-jupyter WITHOUT GPU support

To run the container with GPU support, a local data volume and , run:

docker run -d -it -p 8848:8888 -v $(pwd)/data:/home/jovyan/work -e GRANT_SUDO=yes -e JUPYTER_ENABLE_LAB=yes --user root --restart always --name gpu-jupyter_1 gpu-jupyter 

Parameter

The script generate-Dockerfile.sh has multiple parameters:

• -c|--commit: specify a commit or "latest" for the docker-stacks, the default commit is a working one.

• -s|--slim: Generate a slim Dockerfile. As some installations are not needed by everyone, there is the possibility to skip some installations to reduce the size of the image. Here the docker-stack scipy-notebook is used instead of datascience-notebook that comes with Julia and R. Moreover, none of the packages within src/Dockerfile.usefulpackages is installed.

• --no-datascience-notebook: As the name suggests, the docker-stack datascience-notebook is not installed on top of the scipy-notebook, but the packages within src/Dockerfile.usefulpackages are.

• --no-useful-packages: On top of the docker-stack datascience-notebook, the essential gpulibs are installed but not the packages within src/Dockerfile.usefulpackages.

The script start-local.sh is a wrapper for a quick configuration of the underlying docker-compose.yml. It is equal to these commands:

docker build -t gpu-jupyter .build/
docker run -d -p [port]:8888 gpu-jupyter

Tracing

With these commands we can see if everything worked well:

bash show-local.sh  # a env-var safe wrapper for a 'docker-compose logs -f'
docker ps
docker logs [service-name]

In order to stop the local deployment, run:

./stop-local.sh

Deployment in the Docker Swarm

A Jupyter instance often requires data from other services. If that data-source is containerized in Docker and sharing a port for communication shouldn't be allowed, e.g., for security reasons, then connecting the data-source with GPU-Jupyter within a Docker Swarm is a great option!

Set up Docker Swarm and Registry

This step requires a running Docker Swarm on a cluster or at least on this node. In order to register custom images in a local Docker Swarm cluster, a registry instance must be deployed in advance. Note that the we are using the port 5001, as many services use the default port 5000.

sudo docker service create --name registry --publish published=5001,target=5000 registry:2
curl 127.0.0.1:5001/v2/

This should output {}. \

Afterwards, check if the registry service is available using docker service ls.

Configure the shared Docker network

Additionally, GPU-Jupyter is connected to the data-source via the same docker-network. Therefore, This network must be set to attachable in the source's docker-compose.yml:

services:
  data-source-service:
  ...
      networks:
      - default
      - datastack
  ...
networks:
  datastack:
    driver: overlay
    attachable: true  

In this example,

• the docker stack was deployed in Docker swarm with the name elk (docker stack deploy ... elk),
• the docker network has the name datastack within the docker-compose.yml file,
• this network is configured to be attachable in the docker-compose.yml file
• and the docker network has the name elk_datastack, see the following output:

  sudo docker network ls
  # ...
  # [UID]        elk_datastack                   overlay             swarm
  # ...

The docker network name elk_datastack is used in the next step as a parameter.

Start GPU-Jupyter in Docker Swarm

Finally, GPU-Jupyter can be deployed in the Docker Swarm with the shared network, using:

./generate-Dockerfile.sh
./add-to-swarm.sh -p [port] -n [docker-network] -r [registry-port]
# e.g. ./add-to-swarm.sh -p 8848 -n elk_datastack -r 5001

where:

• -p: port specifies the port on which the service will be available.
• -n: docker-network is the name of the attachable network from the previous step, e.g., here it is elk_datastack.
• -r: registry port is the port that is published by the registry service, see Set up Docker Swarm and Registry.

Now, gpu-jupyter will be accessable here on localhost:8848 with the default password asdf and shares the network with the other data-source, i.e., all ports of the data-source will be accessable within GPU-Jupyter, even if they aren't routed it the source's docker-compose file.

Check if everything works well using:

sudo docker service ps gpu_gpu-jupyter
docker service ps gpu_gpu-jupyter

In order to remove the service from the swarm, use:

./remove-from-swarm.sh

Configuration

Please set a new password using src/jupyter_notebook_config.json. Therefore, hash your password in the form (password)(salt) using a sha1 hash generator, e.g., the sha1 generator of sha1-online.com. The input with the default password asdf is appended by a arbitrary salt e49e73b0eb0e to asdfe49e73b0eb0e and should yield the hash string as shown in the config below. Never give away your own unhashed password!

Then update the config file as shown below and restart the service.

{
  "NotebookApp": {
    "password": "sha1:e49e73b0eb0e:32edae7a5fd119045e699a0bd04f90819ca90cd6"
  }
}

Updates

Update CUDA to another version

Please check version compatibilities for CUDA and Pytorch respectively CUDA and Tensorflow previously. To update CUDA to another version, change in Dockerfile.header the line:

FROM nvidia/cuda:10.1-base-ubuntu18.04

and in the Dockerfile.pytorch the line:

cudatoolkit=10.1

Then re-generate and re-run the image, as closer described above:

./generate-Dockerfile.sh
./start-local.sh -p 8848

Update Docker-Stack

The docker-stacks are used as a submodule within .build/docker-stacks. Per default, the head of the commit is reset to a commit on which gpu-jupyter runs stable. To update the generated Dockerfile to a specific commit, run:

./generate-Dockerfile.sh --commit c1c32938438151c7e2a22b5aa338caba2ec01da2

To update the generated Dockerfile to the latest commit, run:

./generate-Dockerfile.sh --commit latest

A new build can last some time and may consume a lot of data traffic. Note, that the latest version may result in a version conflict! More info to submodules can be found in this tutorial.
