Docker“错误：在分配给网络的默认值中找不到可用的，不重叠的IPv4地址池”

我有一个apkmirror-scraper-compose具有以下结构的目录：

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

我正在尝试运行以下命令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

其中，Dockerfile用于tor为

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"]

那privoxy是

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

其中config由两个线

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

而Dockerfile对于scraperIS

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requests。最后，该程序newnym.py旨在简单地测试使用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)))

在docker-compose build成功建立，但如果我尝试docker-compose up，我得到以下错误信息：

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

我尝试搜索有关此错误消息的帮助，但找不到任何帮助。是什么导致此错误？

回答：

遵循彼得·豪格）的评论，在跑步时，docker network ls我发现（其中包括）以下内容：

NETWORK ID          NAME                                    DRIVER              SCOPE
dc6a83d13f44        bridge                                  bridge              local
ea98225c7754        docker_gwbridge                         bridge              local
107dcd8aa889        host                                    host                local

NAME和DRIVER两者的界线host似乎就是他所说的“在您的主机上已经创建的网络”。因此，按照https://gist.github.com/bastman/5b57ddb3c11942094f8d0a97d461b430，我运行了命令

docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

现在docker-compose up可以工作（尽管newnym.py会产生错误）。
