Using Docker to run the ExatrkX Pipelines - SPRACE/track-ml Wiki

Installing Docker

For installing Docker CE, follow the official instructions for your supported Linux distribution. For convenience, the tutorial below includes instructions on installing Docker for Linux Ubuntu and Debian distros.

Setting up Docker

The following steps can be used to setup NVIDIA Container Toolkit on Ubuntu LTS - 16.04, 18.04, 20.4 and Debian - Stretch, Buster distributions.

Docker-CE on Ubuntu can be setup using Docker’s official convenience script:

$ curl | sh \
  && sudo systemctl --now enable docker

Setting up NVIDIA Container Toolkit

If you want to follow a tutorial for another distro or with more detailed instructions, please follow de original NVIDIA instructions.

Setup the stable repository and the GPG key:

$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
   && curl -s -L | sudo apt-key add - \
   && curl -s -L$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

Install the nvidia-docker2 package (and dependencies) after updating the package listing:

$ sudo apt-get update
$ sudo apt-get install -y nvidia-docker2

Restart the Docker daemon to complete the installation after setting the default runtime:

$ sudo systemctl restart docker

At this point, a working setup can be tested by running a base CUDA container:

$ sudo docker run --rm --gpus all nvidia/cuda:11.0-base nvidia-smi

This should result in a console output shown below:

This default installation of Docker only allows to run Docker containers as a sudo. If you want to enable Docker runs without privileges, check the following link: Post-installation steps for Linux

Creating a Docker image to run the ExatrkX pipeline

At the root of this repository, run the following command to create a Docker image from the Dockerfile configuration file:

$ docker build -t exatrkx-docker-gpu .

Running ExatrkX pipeline example using Docker Container

The volume in this Docker configuration are defined to be used for input and output data. For exemplification, this tutorial will use the folder data in this repository:

At the root of this repository, set the env var EXATRKX_DATA to define you folder to I/O:

export EXATRKX_DATA=$PWD/data

Go to examples folder:

cd Pipelines/TrackML_Example/

Run the following command to create a Docker container from the image configuration file:

sudo docker run --rm -it --init --gpus=all --ipc=host --user="$(id -u):$(id -g)" -v $PWD:/app -v $EXATRKX_DATA:/data exatrkx-docker-gpu traintrack --pipeline_config configs/pipeline_fulldataset.yaml

If you want to use other paths to run you pipeline, you need to change the paths in the pipeline configurations files. E.g.:

Pipelines/TrackML_Example/LightningModules/Processing/prepare_dockertest.yaml #configuration file to the Processing step from the pipeline

The change the Docker volume configuration, you need to change de Dockerfile in the root of this repository.
