image-pdm

Example Docker Image: PDM

Example of a production Docker image for an application that uses PDM to manage its dependencies.

• Multi-stage build with separate build and production stages.
• Uses PDM to install dependencies.
• PDM is installed in a separate stage and can used in any stage without adding it with bind mounts:

  RUN --mount=type=bind,from=pdm,source=/home/app/pdm,target=/home/app/pdm \
      /home/app/pdm/bin/pdm --no-cache install ...
  

• Application runs as a non-privileged user.
• Installs system updates to get the latest bug fixes and security updates.

See the Dockerfile for a detailed walk-through.

Building the image

Use the following command to build the production image:

docker buildx build --target production --tag example-image-pdm:latest .

You can also add the --progress plain argument to see the complete build log.

Running the example

Provided docker-compose.yml allows you to start the application in two configurations: production (example_prod), and development (example_dev).

Run them with the following command:

docker compose up --build

You can verify that the application works on the following links:

• Production: http://localhost:8000/
• Development: http://localhost:8001/
