我有一个apkmirror-scraper-compose目录，结构如下:

.
├── docker-compose.yml
├── privoxy
│   ├── config
│   └── Dockerfile
├── scraper
│   ├── Dockerfile
│   ├── newnym.py
│   └── requirements.txt
└── tor
    └── Dockerfile

我正在尝试运行以下docker-compose.yml:

version: '3'

services:
  privoxy:
    build: ./privoxy
    ports:
      - "8118:8118"
    links:
      - tor

  tor:
    build:
      context: ./tor
      args:
        password: ""
    ports:
      - "9050:9050"
      - "9051:9051"

  scraper:
    build: ./scraper
    links:
      - tor
      - privoxy

Dockerfile for tor在哪里

FROM alpine:latest
EXPOSE 9050 9051
ARG password
RUN apk --update add tor
RUN echo "ControlPort 9051" >> /etc/tor/torrc
RUN echo "HashedControlPassword $(tor --quiet --hash-password $password)" >> /etc/tor/torrc
CMD ["tor"]

这对于privoxy是

FROM alpine:latest
EXPOSE 8118
RUN apk --update add privoxy
COPY config /etc/privoxy/config
CMD ["privoxy", "--no-daemon"]

其中配置由两行组成

listen-address 0.0.0.0:8118
forward-socks5 / tor:9050 .

scraper的Dockerfile为

FROM python:2.7-alpine
ADD . /scraper
WORKDIR /scraper
RUN pip install -r requirements.txt
CMD ["python", "newnym.py"]

其中requirements.txt包含单行请求。最后，程序newnym.py被设计成简单地测试使用Tor更改IP地址是否有效:

from time import sleep, time

import requests as req
import telnetlib


def get_ip():
    IPECHO_ENDPOINT = 'http://ipecho.net/plain'
    HTTP_PROXY = 'http://privoxy:8118'
    return req.get(IPECHO_ENDPOINT, proxies={'http': HTTP_PROXY}).text


def request_ip_change():
    tn = telnetlib.Telnet('tor', 9051)
    tn.read_until("Escape character is '^]'.", 2)
    tn.write('AUTHENTICATE ""\r\n')
    tn.read_until("250 OK", 2)
    tn.write("signal NEWNYM\r\n")
    tn.read_until("250 OK", 2)
    tn.write("quit\r\n")
    tn.close()


if __name__ == '__main__':
    dts = []
    try:
        while True:
            ip = get_ip()
            t0 = time()
            request_ip_change()
            while True:
                new_ip = get_ip()
                if new_ip == ip:
                    sleep(1)
                else:
                    break
            dt = time() - t0
            dts.append(dt)
            print("{} -> {} in ~{}s".format(ip, new_ip, int(dt)))
    except KeyboardInterrupt:
        print("Stopping...")
        print("Average: {}".format(sum(dts) / len(dts)))

docker-compose构建成功，但如果我尝试docker-compose up，我得到以下错误消息:

Creating network "apkmirrorscrapercompose_default" with the default driver
ERROR: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

我尝试搜索关于此错误消息的帮助，但无法找到任何帮助。是什么导致了这个错误?
