Docker images for Apache/mod_wsgi.

MOD_WSGI (DOCKER)

The mod_wsgi-docker package is a companion package for Apache/mod_wsgi. It contains configurations for building docker images which bundle up Apache and mod_wsgi-express.

Available images

Prebuilt images available are:

• grahamdumpleton/mod-wsgi-docker:python-2.7
• grahamdumpleton/mod-wsgi-docker:python-2.7-onbuild
• grahamdumpleton/mod-wsgi-docker:python-3.3
• grahamdumpleton/mod-wsgi-docker:python-3.3-onbuild
• grahamdumpleton/mod-wsgi-docker:python-3.4
• grahamdumpleton/mod-wsgi-docker:python-3.4-onbuild
• grahamdumpleton/mod-wsgi-docker:python-3.5
• grahamdumpleton/mod-wsgi-docker:python-3.5-onbuild

See mod-wsgi-docker on Docker Hub for more information.

How to use these images

Create a Dockerfile in your Python web application project:

FROM grahamdumpleton/mod-wsgi-docker:python-2.7-onbuild
CMD [ "hello.wsgi" ]

The list of CMD arguments should consist of the path to the WSGI script file for the Python web application and any additional arguments you wish to have supplied to the mod_wsgi-express command.

These 'onbuild' images include multiple ONBUILD triggers, which should be all you need to bootstrap most applications. The build will COPY the current directory into /app and then RUN pip install on any requirements.txt file. It is possible to define pre and post hooks to enable additional system packages to be installed and for additional application setup to be performed.

You can then build and run the Docker image:

docker build -t my-python-app .
docker run -it --rm -p 8000:80 --name my-running-app my-python-app

The Python web application should then be accessible at port 8000 of the docker host.

Note that although your specific Python web application when run will run as the non root user www-data, the Apache server itself will initially start up as the root user. Some Docker runtime environments however may be set up so as to prohibit you running your container as the root user and require a non root user from the outset.

If this is the case, you can use:

FROM grahamdumpleton/mod-wsgi-docker:python-2.7-onbuild
USER $MOD_WSGI_USER:$MOD_WSGI_GROUP
CMD [ "hello.wsgi" ]
