> Docker Alpine image with Python and pip.
## Overview
This Docker image provides a minimal Python installation built on Alpine Linux. It uses Alpine's Python packages but removes the PEP 668 restriction, allowing you to install packages with pip without additional flags or virtual environments.
## Features
- **Small footprint**: ~50MB runtime image using Alpine Linux
- **Python 3.12.11**: Alpine packages with PEP 668 restriction removed
- **Minimal installation**: Only Python and pip included
- **Non-root user**: Enhanced security with dedicated python user
- **Volume mounting**: Easy code and data access through `/app`
## Quick Start
```bash
# Pull the image
docker pull ragedunicorn/python:latest
# Run Python interactively
docker run -it --rm ragedunicorn/python:latest
```
For development and building from source, see [DEVELOPMENT.md](DEVELOPMENT.md).
## Usage
The container uses Python as the entrypoint, so any Python parameters can be passed directly to the `docker run` command.
### Basic Usage
```bash
# Using latest version
docker run -v $(pwd):/app ragedunicorn/python:latest [python-options]
# Using specific Python version (latest Alpine build)
docker run -v $(pwd):/app ragedunicorn/python:3 [python-options]
# Using exact version combination
docker run -v $(pwd):/app ragedunicorn/python:3-alpine3.22.1-1 [python-options]
```
### Examples
#### Run Python Script
```bash
docker run -v $(pwd):/app ragedunicorn/python:latest script.py
```
#### Interactive Python Shell
```bash
docker run -it --rm ragedunicorn/python:latest
```
#### Execute Python Code
```bash
docker run --rm ragedunicorn/python:latest -c "print('Hello, World!')"
```
#### Install Package and Run
```bash
docker run -v $(pwd):/app ragedunicorn/python:latest /bin/sh -c "pip install requests && python script.py"
```
#### Check Python Version
```bash
docker run --rm ragedunicorn/python:latest --version
```
#### Run Tests
```bash
docker run -v $(pwd):/app ragedunicorn/python:latest /bin/sh -c "pip install pytest && python -m pytest"
```
## Docker Compose Usage
This repository includes Docker Compose configurations for easier usage and common Python development workflows.
### Basic Setup
1. Create an `app` directory:
```bash
mkdir -p app
```
2. Place your Python files in `app/`
3. Run Python using docker compose:
```bash
docker compose run --rm python script.py
```
### Example Configuration
The `examples/` directory contains a hello-world example:
#### Hello World Example (`examples/docker-compose.yml`)
```bash
# Run the hello world example
cd examples && docker compose run --rm hello-world
```
### Environment Variables
The compose configuration supports:
- `PYTHON_VERSION`: Specify Python image version (default: latest)
- `PYTHONUNBUFFERED`: Unbuffered output (set to 1)
- `TERM`: Terminal type for colored output
### Tips
1. **Custom Commands**: Override the default command:
```bash
docker compose run --rm python -c "import sys; print(sys.version)"
```
2. **Development Mode**: Use the development compose file for building locally:
```bash
docker compose -f docker-compose.dev.yml build
docker compose -f docker-compose.dev.yml run --rm python script.py
```
3. **Persistent Settings**: The repository includes a `.env` file with default settings:
```env
PYTHON_VERSION=latest
```
## Building Custom Images
To create a custom image with your required packages:
```dockerfile
FROM ragedunicorn/python:latest
# Install Python packages
USER root
RUN pip install requests numpy pandas
USER python
# Copy your application
WORKDIR /app
COPY . .
CMD ["python", "app.py"]
```
## Versioning
This project uses semantic versioning that matches the Docker image contents:
**Format:** `{python_major_version}-alpine{alpine_version}-{build_number}`
Examples:
- `3-alpine3.22.1-1` - Python 3 on Alpine 3.22.1, build 1
- `latest` - Most recent stable release
For detailed release process and versioning guidelines, see [RELEASE.md](RELEASE.md).
## Automated Dependency Updates
This project uses [Renovate](https://docs.renovatebot.com/) to automatically check for updates to:
- Alpine Linux base image version (all major, minor, and patch updates)
Renovate runs weekly (every Monday) and creates pull requests when updates are available. The configuration tracks Alpine Linux releases, creating pull requests for each update.
