Docker错误:无法在默认值中找到一个可用的、不重叠的IPv4地址池分配给网络。
我有一个目录apkmirror-scraper-compose，其结构如下:
.
├── 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的值为
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requests。最后，程序newnym.py被设计用来简单地测试使用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成功构建，但如果我尝试docker-compose up，我会得到以下错误消息:
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?
