when i use this docker to run a fastapi like:
@app.get("/testyf")
async def root():
return {"message": "Hello World"}
it runs fine, but if i insert a socket listener like;
class Listener(threading.Thread):
def __init__(self, port):
threading.Thread.__init__(self)
self.port = port
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
self.sock.settimeout(10000000)
self.sock.bind(("0.0.0.0", port))
self.sock.listen(0)
def run(self):
print("listener started")
self.sock.accept()
lst = Listener(9011) # create a listen thread
lst.start() # then start
then it will not run and the errorlog is:

OSError: [Errno 98] Address already in use
(actually, the socket is a prometheus method)
does someone have idea?
