Yet Another Docker Example. Now with Python!

README.md

How to run it

$ docker build -t yade -f Dockerfile
$ docker run --network host -d --rm -p 8000:8000 yade
$ curl localhost:8000

Explanation:

• --network host allows Docker to use network-based functions, in host mode.
• -d runs Docker as daemon (running at the background)
• --rm removes the container if exited
• -p 8000:8000 port-forwarding for container:8000 to host:8000

This should output something like this:

juanjo@debian:~/Docker$ curl localhost:8000
Hello world!

app.py

from http.server import BaseHTTPRequestHandler, HTTPServer

class Handler(BaseHTTPRequestHandler):

    def do_GET(self):
        self.send_response(200)
        self.end_headers()
        self.wfile.write(b'Hello world!')

if __name__ == '__main__':
    server = HTTPServer(('localhost', 8000), Handler)
    print("Server running on port 8000.")
    server.serve_forever()
