Flask, uWSGI and Nginx in a container with Enivornment Variable.

Argument parameters may not be supplied to a Flask app via docker command line when the entrypoint is supervisord. This sample shows a workaround on how environment variables can be used to achieve the same.

Build and run

• docker build -t webapp .
• docker run -d -p 80:80 -e ReturnData="Hello Kaushik" webapp

See the output

• curl -X GET http://localhost/
