Question

我正在尝试编写一个使用Privoxy和Tor作为Docker多容器应用程序中的单独服务的应用程序。名为apkmirror-scraper-compose的目录具有以下结构：

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

docker-compose.yml

version: '3'

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

  tor:
    build:
      context: ./tor
      args:
        password: "foo"

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

Dockerfile目录中的tor为

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

和privoxy中的

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

最后，Dockerfile的{{1}}是

scraper

其中FROM python:2.7-alpine ADD . /scraper WORKDIR /scraper COPY run.sh /scraper/run.sh RUN chmod +x /scraper/run.sh ENTRYPOINT /scraper/run.sh包含单行

run.sh

基本上，使用until nc -z tor 9050; do echo "Waiting for tor..." && sleep 1; done;命令，我正在等待端口号nc -z的目标tor正在侦听。但是，如果我运行9050后跟docker-compose build，我会看到以下内容：

docker-compose up

据我所知https://docs.docker.com/compose/compose-file/#links，“链接服务的容器可以在与别名相同的主机名上访问，如果没有指定别名，则可以访问服务名称”。由于我没有指定别名，因此主机名应为Waiting for tor...，对吧？有人可以解释为什么这不起作用吗？

在Docker-compose中，看不到其他服务的主机名
