Docker — Containers for Reproducibility

The industry-standard container platform: package your entire computational environment so it runs identically anywhere — the strongest answer to 'works on my machine'.

Overview

Docker freezes your environment — OS libraries, Python version, every dependency — into an image that runs identically on any machine. For computational research, a Dockerfile published beside your paper is the difference between ‘should reproduce’ and ‘reproduces’.

Why researchers use it

  • True environment capture — system libraries included, not just Python packages
  • Reviewer-proof — ‘docker run’ reproduces your analysis on any machine
  • Industry standard — skills and images transfer everywhere

Getting started

  1. Install Docker Desktop (free for education/small orgs) or Engine on Linux.
  2. Write a Dockerfile: base image, COPY your code, RUN pip install -r requirements.txt.
  3. docker build, docker run, then publish the image hash in your paper’s repo.

The honest review

Strengths. The ecosystem: prebuilt scientific images (Jupyter, R, CUDA) cover most needs, and every cloud and many journals’ artifact-evaluation tracks speak Docker natively.

Limitations. Requires root/admin — which is exactly why HPC clusters refuse it (use Apptainer there); Docker Desktop licensing applies to large companies; images bloat without care.

When NOT to use this On shared university clusters Docker is usually banned outright — learn Apptainer for that world. And for a solo pure-Python project, a pinned conda/uv environment may be all the reproducibility you need.
