Docker-compose尝试一次执行多个RUN

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作为一个单一的Dockerfile执行完美，但是当我切入这两个Dockerfile，并试图用docker docker-compose up来执行它docker-compose up ，它只是在这一行失败了，升级，升级也搞砸了。 不安装软件包而不刷新dpkg：

看起来它试图用下一个命令执行apt-get ，即RUN mkdir /var/run/sshd 。 这是为什么？

Answer 1

看起来它试图用下一个命令执行apt-get ，即RUN mkdir /var/run/sshd 。 这是为什么？

由于前一个RUN apt-get命令结尾的\ 。

 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考虑包括下一个直播的多线（ RUN mkdir one ）
