docker - Docker-compose尝试一次执行多个RUN

Question

我有这个docker应用程序结构:
docker-compose.yml

lanti-debian-base:
  build: ./debian
  container_name: lanti-debian-base
  ports:
    - "8080:80"
    - "8081:443"
    - "8082:22"
lanti-debian-web:
  build: ./web
  container_name: lanti-debian-web
  ports:
    - "8080:80"
    - "8081:443"
    - "8082:22"
  volumes:
    - "/home/core/www:/var/www:rw"

这个Dockerfiles作为一个单独的Dockerfile可以完美执行，但是当我切入这两个Dockerfile并尝试使用 docker-compose up执行它时，它只是在这一行失败了，更新，升级也搞砸了。不安装软件包并且不刷新dpkg:

ERROR: Service 'lanti-debian-base' failed to build: The command '/bin/sh -c apt-get -y update     && time apt-get -y dist-upgrade     && apt-get -y --force-yes install --fix-missing         dialog         apt-utils         sudo         supervisor         openssh-server RUN mkdir /var/run/sshd' returned a non-zero code: 100

看起来它正在尝试使用下一个即将到来的命令 apt-get执行 RUN mkdir /var/run/sshd。这是为什么？

Answer 1

Looks like it's trying to execute apt-get with the next coming command, which is RUN mkdir /var/run/sshd. Why is that?

由于前一个 \命令末尾有 RUN apt-get，

apt-get -y --force-yes install --fix-missing \
        dialog \
        apt-utils \
        sudo \
        supervisor \
        openssh-server \ <====

### Start of OpenSSH setup
RUN mkdir /var/run/sshd

这迫使Docker考虑包括下一个Directove( RUN mkdir one)的多行。
