Weenect python-docker

This repositary provides the base python docker image for Weenect development environment.

You can find :

• a python 2.7 image : weenect/python:2.7
• a python stackless 2.7 image : weenect/python:stackless2.7

Usage

The images are all build with the same structure.

Each image provides a folder tree for the project :

• /opt/dev : base project folder
• /opt/dev/conf : folder to put the configuration of the project
• /opt/dev/src : folder to put the sources of the project (use a volume when running a container)
• /opt/dev/venv : the virtual env (declared as a volume to cache all project dependency)

And a bash script as an entry point. This script does the following action :

• Enable the virtualenv
• Run the python setup.py develop command inside the /opt/dev/src folder
• Replace all $VARIABLE using environment variables in the /opt/dev/conf/config_original.cfg file and create a new file /opt/dev/conf/config.cfg (usefull when linking containers)
• Execute the file /opt/dev/conf/packages if it exists (for example to post install additional dependencies)
• Run the args of the entrypoint as a command (CMD of the extending Dockerfile)

Example

A simple example of a Dockerfile extending one of these images :

FROM weenect/python:2.7

COPY myconfigfile.cfg /opt/dev/conf/config_original.cfg

EXPOSE 8080

CMD ["/opt/dev/venv/bin/my-project-command", "serve", "/opt/dev/conf/config.cfg"]
