fspot/flask-sockets repository overview

⁠docker-flask-sockets

Docker trusted build test. Contains hello.py from https://github.com/kennethreitz/flask-sockets/⁠ (overridable).

⁠Run container

Basic :

$ sudo docker run -t -i -p 8000:8000 fspot/flask-sockets

Override the code inside the container and use a volume from the host (persistant) :

$ sudo docker run -t -i -p 8000:8000 -v /tmp/code:/code/work fspot/flask-sockets

Now you're in the container (bash prompt).

⁠Launch project

Inside the container :

$ gunicorn -k flask_sockets.worker -b 0.0.0.0:8000 hello:app  # needs hello.py with app (wsgi compliant)

As we've bound port 8000 of the host to 8000 of the container, then :

$ curl localhost:8000

should work in both.

Also, open your browser and go to http://www.websocket.org/echo.html⁠. Put ws://localhost:8000/echo, then connect : websocket works.
