python - docker "ERROR: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network"

Question

我有一个目录apkmirror-scraper-compose，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

tor 的 Dockerfile 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"]

privoxy 是

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

其中 config 由两行组成

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

scraper 的 Dockerfile 是

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，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)))

docker-compose build 构建成功，但如果我尝试 docker-compose up，我会收到以下错误消息:

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

我尝试搜索有关此错误消息的帮助，但找不到任何帮助。是什么导致了这个错误？

Answer 1

我看到它表明 docker 可能处于创建网络的最大值。命令 docker network prune 可用于删除至少一个容器未使用的所有网络。

我的问题最终变成了 Robert评论:openvpn service openvpn stop 的问题“解决了”问题。
