How to containerize Python applications with Docker

on YouTube ↗26m

" summary

Step-by-step show of containerizing a simple Python script and a FastAPI web app using python:3.9 base image, building Dockerfiles that add source, run `pip install` and set CMD, and a second Dockerfile that uses a working dir, `pip freeze` -> requirements.txt and pip install --no-cache-dir. Demonstrates interactive input with `docker run -it`, exposes the server with --host 0.0.0.0 and maps ports, then runs detached with docker run -p 80:80 -d and successfully execs into the container to inspect files.
