This image was specifically crafted to be as small as possible while also giving a good basic packaging. We are trying to follow the best practices of Docker and Kubernetes with this image to improve speed and security.
This image is based on alpine linux and provides the following features:
- Python 3.x
- uwsgi with python3, spooler and cache plugin loaded and sane default settings
- pyscop2 and pyscop2-binary
- wait-for-postgres command (wait for the DB defined in $POSTGRES_HOST)
- Possibility to add additional packages and build-only packages
This images is intended to be used with a standard python3.x and django2.x project.
The project structure should look roughly like this:
.
├── .dockerignore
├── .git/
├── .gitignore
├── Makefile
├── README.md
├── docker-compose.yml
└── project
├── .build
│ └── runtime-packackes.txt
│ └── build-packages.txt
├── myproject
│ ├── __init__.py
│ ├── apps
│ ├── settings
│ ├── static
│ ├── templates
│ ├── urls.py
│ └── wsgi.py
├── Dockerfile
├── init.sh
├── test.sh
└── setup.py
The corresponding dockerfile in the subproject using this base image can be as close to zero as:
FROM mecodia/python-base:latest
ENV POSTGRES_HOST db.example.com
RUN mkdir -p var/static
The image should be ran with the following command as the bare minimum:
uwsgi --http-socket 0.0.0.0:8000 --module myproject.wsgi:application --show-config
or if we use a prerun script:
sh ./init.sh uwsgi --http-socket 0.0.0.0:8000 --module myproject.wsgi:application --show-config
Edit and use the build.sh script to push a new image tag to docker hub.
