Docker-compose unable to connect static ip

Question

For some needs I'd like a python app to connect to a tor proxy but instead of the DNS I want to use the static ip. Indeed when I

I'm unable to make it happen. The request is always timed out when I want to connect to the database.

Here is my docker-compose file :

version: "3.9"
services:
  test:
    image: busybox
    command: ifconfig
    networks:
      app_net:
        ipv4_address: 172.18.18.9

  app:
    build: ./python
    depends_on:
      - tor

  tor:
    build:
      context: ./tor
    container_name: tor
    environment:
      - TOR_INSTANCES=1
      - TOR_HASHED_PASSWORD=16:D87F66F5B5E2A6BC605544DBB4720DAD433C1E8CE7D18F835D58A4353E
      - TOR_PROXIES_CONTROLLER_AUTH_PASSWORD=testtor
      - TOR_CONTROLLER_HOST=172.18.18.10
    ports:
      - "9050-9060:9050-9060"
      - "10000-10050:10000-10050"
    networks:
      app_net:
        ipv4_address: 172.18.18.10

networks:
  app_net:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 172.18.18.0/24
          gateway: 172.18.18.1

My python code is very simple, this is what i'm trying to do :

• Get IP from requests (without proxies)
• Same but with proxy
• Renew proxy
• Perform requests again

The first request passes well but then it timeouts with the proxies. Obvisously I can't renew the IP either as the ip so not resolved.

^[[Dapp_1   | After request ::  https://ifconfig.io/ip 200 82.123.30.131
app_1   | 
app_1   | SOCKSHTTPSConnectionPool(host='ifconfig.io', port=443): Max retries exceeded with url: /ip (Caused by NewConnectionError('<urllib3.contrib.socks.SOCKSHTTPSConnection object at 0xffffbcb16940>: Failed to establish a new connection: [Errno -2] Name or service not known'))

app_1   |     control_socket.connect((self.address, self.port))
app_1   | TimeoutError: [Errno 110] Connection timed out

However if I only execute the tor docker-container, and I replace the tor proxy by "localhost", it works totally fine :

    def add_proxies(self):
        self.http.proxies['http'] = 'socks5://localhost:9051'
        self.http.proxies['https'] = 'socks5://localhost:9051'

    def renew_proxy_ip(self):
        with Controller.from_port(port=10001) as controller:
            controller.authenticate(password="testtor")
            print("Authentication :: ", controller.is_authenticated())
            controller.signal(Signal.NEWNYM)

Output is expected

After request ::  https://ifconfig.io/ip 200 2a01:cb04:be0:b300:d44d:f8d3:6328:b2f1

After request ::  https://ifconfig.io/ip 200 2a00:1768:6001:28:2236::1

Authentication ::  True
After request ::  https://ifconfig.io/ip 200 2a03:4000:37:645::

I added a ifconfig busybox to see if ip is correctly mapped, which is the case :

test_1  |           inet addr:172.18.18.9  Bcast:172.18.18.255  Mask:255.255.255.0

I created a repo where you can reproduce the issue : https://github.com/thibault-lr/docker-static-ip simply with a docker-compose up

I'm a bit obliged to proceed so, the controller authication requires an IP to connect to. I've been stuck to this for a while, I'd like to know if someone experienced this issue already ? I'm on macos and tried on a linux server it remains the same

There are other solutions that I didn't explore if this is not possible :

• Use the telnet to connect to tor network using a DNS
• Auth with socket files

Huge thanks in advance ! TL
