Summary

This primer, originally published in December 2017 and updated in August 2020, introduces Docker containers as lightweight virtual machines for data scientists. It highlights Docker's benefits for reproducibility, portability of compute environments, and strengthening engineering skills, particularly for machine learning workflows. The article defines core Docker terminology, including Image, Container, Dockerfile, Commit, DockerHub, and Layer. It then details the creation of a Docker image using a Dockerfile, explaining key statements like FROM, LABEL, ENV, RUN, EXPOSE, VOLUME, WORKDIR, ADD (now COPY), and CMD. The guide concludes with instructions on building and running containers, saving container states, listing containers and images, and pushing images to DockerHub, emphasizing its utility for sharing reproducible research and deploying models.

Key takeaway

For data scientists aiming to improve workflow reproducibility and portability, adopting Docker is crucial. You can prototype locally and seamlessly transition to remote GPU machines like AWS by containerizing your environment, ensuring all dependencies, aliases, and configurations are preserved. This approach also simplifies sharing research and deploying models as scalable applications, significantly boosting efficiency and collaboration.

Key insights

Docker containers enhance data science reproducibility, portability, and deployment capabilities by encapsulating compute environments.

Principles

• Reproducibility requires encapsulating all dependencies.
• Portability enables seamless compute environment transitions.
• Dockerfiles define images through layered instructions.

Method

Create a Dockerfile with FROM, RUN, and CMD statements to define an image, then build the image and run it as a container, committing changes to save new image states.

In practice

• Use Docker for consistent deep learning environment setup.
• Deploy models as REST API endpoints via Docker.
• Share research environments using DockerHub.
