The default value of SECRET_KEY was hard-coded in the settings.py which would turn out to be used all the time even if people are not forced to change it. So this commit removes that value and instead gets the SECRET_KEY from the environment variable.
Closes#99
Several Changes:
- Uwsgi now listens on two sockets 8080 for http protocol and 8000 for uwsgi protocol
- Add a read_timeout in documentation for Nginx configuration
- Expose 8024 properly in Core image
- Expose 8080 and 8000 both in Web image
- Rearange the commands to get even less number of layers.
- Add SIGINT as stop signal in web because uwsgi needs it shut down gracefully
- Enable threads in default uwsgi configuration
Fix#64, Fix#15
