Dec 07, 2019 · A few days ago, I created a Docker build for Flask with PostgreSQL (both with Alpine Linux and with Debian Linux). Installing psypcopg-2 binary (required for Postgres) requires you to build the package from source. Now the Docker image grows in size, as it still contains the build artifacts. The solution? Multi-stage Docker builds. Let’s say we have the following docker-compose.yml file ...
FROM dependencies AS build. WORKDIR /app. COPY . /app. # Build / Compile if required. # --- Release with Alpine ----. FROM python:3.6-alpine3.7 AS release.

Multi-stage Docker builds for Python projects Multi-stage builds can help reduce your Docker image sizes in production. This has many benefits: Development dependencies may potentially expose extra security holes in your system (I've yet to see this happen, but why not be cautious if it's easy to be so?), but mostly by reducing image size you make it faster for others to docker …
The concept of multi-stage builds is simple: Install development dependencies, build all the stuff you need, then copy over just the stuff you need to run in production in a brand new image without installing development dependencies not needed to run the application.
