docker-python-flask

My suggestion of a Production Ready Docker image for a Python / Flask application.

The image will be:

• Small: around 50MB
• For production: no debugging servers involved
• Unique: one source code and one image for all environments
• More secure: developers don't know production's credentials
• Clean: source code includes only one extra file (Dockerfile)

Why is this image smaller than others?

• Based on Alipine image
• Cleanes the system after apk add commands
• Uses Alpine uwsgi package
• Doesn't use Supervisord. It uses a bash's job as described here

Environment variables

This demo uses a config setting named "MY_MODULE.name". To override it, you should provide an environment variable called "MODULE_NAME". For example:

docker run -e MODULE_NAME=my_name ...

Special thanks

I was able to create this image because I've learned from:
