This repo was created while following along with How to create a great dev environment with Docker by Patrick Loeber
I've tried to update the container in place and avoid using root user to run tasks like you would do in a production environment, but I'm sure this is all terrible and there are much better ways to accomplish.
Learned a bit about Docker, Docker-Compose, VS Code Dev Containers, Python Virtual Environment, Uvicorn, FastAPI, etc.
Hopefully this helps someone struggling with the same video.
- WSL 2 installed
- Docker Desktop installed
I was able to view the website at http://127.0.0.1:8000 on my local machine
I needed to run $ docker-compose up --build --detach in my local machine to build the image and start the containers/network
This Dockerfile is designed to provide a secure and isolated environment for running a FastAPI application with its dependencies in a Python virtual environment.
Key points:
- User and Group Creation:
- The Dockerfile creates a system user and group named "app" with UID and GID set to 1001.
- Directory Setup:
- Directories /code and /py-venv are created for the application and Python virtual environment, respectively.
- Ownership of these directories is set to the "app" user and group.
- Python Virtual Environment:
- A Python virtual environment is created in the /py-venv directory to isolate Python dependencies for the application.
- Dependency Installation:
- Python dependencies specified in the requirements.txt file are installed using pip.
- The pip install commands include an upgrade of pip itself.
- The requirements.txt file is removed after installation to reduce image size.
- Command for Running the Application:
- The default command (CMD) starts the FastAPI application using uvicorn with specified host, port, and reload options.
