development

Models for resolving development issues when working on Python docker services.

if package is external to Dockerfile repository

Copy package into directory before doing Docker build, or provide a git URL to the context key in the docker-compose.yml.

if locally-developed packages are used

When doing development on a Dockerized Python application, locally developed packages also need to be available to the app.

Run a local pypiserver and symlink all locally-developed packages into the packages directory. Expose the URL using PIP_EXTRA_INDEX_URL at build-time (by editing the Dockerfile) or at runtime by running an entrypoint script. To always pick up new changes run docker-compose build --no-cache.

production

notification

Provide authorization credentials via Docker secrets to the application, reading the location from environment variables.

logging

Use built-in Docker logging drivers to direct container stderr logs to the desired location.
