Python development environment in Docker container

Allows you to put the folder ~/dev inside the container ("/home/user/dev") and run the code using the desired version of Python.

Step 0: Clone this repository

git clone https://github.com/svnikolaev/python-docker-envinonment.git
cd python-docker-envinonment

Step 1: Setup secrets_file

Create secrets_file like secrets_file.example and set passwords for users root and user:

root:password1
user:password2

Step 2: Run environment with Docker Compose

Python 3.11 environment

PYTHON_VER=3.11 docker compose up -d --build

Python 3.10 environment

PYTHON_VER=3.10 docker compose up -d --build

environment with http proxy

PYTHON_VER=3.11 HTTP_PROXY=http://example.com:8080 docker compose up -d --build

Step 3: Connect to the container

docker exec -it python_env bash

Step 4: Create virtual environment and install Python packages

cd /path/to/project/dirrectory
virtualenv --python="$(which python)" .venv
source .venv/bin/activate
pip install -r requirements.txt

Step 5: Use Python

example:

(.venv) user@37b61e5ac0fb:~/dev/project$ python -m pytest
=============================== test session starts ===========================
platform linux -- Python 3.11.1, pytest-7.2.1, pluggy-1.0.0

(Optional) Stop Docker Container

docker compose down

(Optional) Build Docker image

You can also create a Docker image for later use.

with Python 3.11

docker build --no-cache \
    --build-arg PYTHON_VER=3.11 \
    --secret id=SECRETS,src=secrets_file -t python_env:3.11 .

with Python 3.10

docker build --no-cache \
    --build-arg PYTHON_VER=3.10 \
    --secret id=SECRETS,src=secrets_file -t python_env:3.10 .

with http proxy

docker build --no-cache \
    --build-arg HTTP_PROXY=http://example.com:8080 \
    --build-arg HTTPS_PROXY=http://example.com:8080 \
    --build-arg PYTHON_VER=3.11 \
    --secret id=SECRETS,src=secrets_file -t python_env:3.11 .
