Container Information

Container Source - GitHub Mirror

This is the Conarx Containers Nginx UWSGI image, it provides the Nginx webserver bundled with UWSGI for serving of Python-based web applications.

Support is included for downloading and installing requirements listed in requirements.txt and optionally persisting these across container restarts.

Static files are by default served by Nginx directly if placed in the static/ folder of an application.

Conarx Containers

All our Docker images are part of our Conarx Containers product line. Images are generally based on Alpine Linux and track the Alpine Linux major and minor version in the format of vXX.YY.

Images built from source track both the Alpine Linux major and minor versions in addition to the main software component being built in the format of vXX.YY-AA.BB, where AA.BB is the main software component version.

Our images are built using our Flexible Docker Containers framework which includes the below features...

• Flexible container initialization and startup
• Integrated unit testing
• Advanced multi-service health checks
• Native IPv6 support for all containers
• Debugging options

Files & Directories

/etc/uwsgi/uwsgi.ini

Main UWSGI configuration. This configuration file will also load /etc/uwsgi/app.ini which is where the application specifics can be configured if the environment variable options are not sufficient.

/etc/uwsgi/app.ini

App specific UWSGI configuration, a copy is included below for reference...

[uwsgi]

chdir = /app

if-dir = /app/.venv
virtualenv = /app/.venv
endif =

workers = 4
module = app
callable = app

Keeping in mind that the workers, module and callable can be customized using environment variables.

/etc/uwsgi/uwsgi.env

Environment variables to export for UWSGI.

/app/static/

This directory will be served directly from Nginx bypassing UWSGI.

/app/.venv/

Virtual environment for the application which must be created beforehand.

This can be created with...

docker run -it --rm \
    -v /path/to/venv:/app/.venv \
    -v /path/to/app/requirements.txt:/app/requirements.txt \
    allworldit/nginx-uwsgi \
    /bin/sh -c "python -m venv /app/.venv; . /app/.venv/bin/activate; pip install --requirement /app/requirements.txt"
