Question

出于学习目的，我创建了这个Dockerfile：

FROM ubuntu:16.10

RUN useradd -m --password=node node && \
  apt-get update && \
  apt-get upgrade -y && \
  apt-get install -y curl && \
  apt-get install -y openssl && \
  apt-get install -y nginx && \
  apt-get -qy autoremove

COPY . /home/node/xxx.com

RUN rm /etc/nginx/sites-enabled/default && \
  cd /etc/nginx/sites-enabled && \
  ln -s /home/node/xxx.com/xxx.nginx.conf default

WORKDIR /home/node

RUN curl -sL https://deb.nodesource.com/setup_7.x | bash - && \
  apt-get install -y nodejs 

RUN curl -L https://get.rvm.io | bash -s stable && \
  /bin/bash -l -c "rvm requirements" && \
  /bin/bash -l -c "rvm install 2.0" && \
  /bin/bash -l -c "gem update --system" && \
  /bin/bash -l -c "gem install bundler --no-ri --no-rdoc" && \
  /bin/bash -l -c "gem install compass  --no-ri --no-rdoc" && \
  /bin/bash -l -c "gem install bootstrap -v 4.0.0.alpha6 --no-ri --no-rdoc"

RUN chown -R node:node /home/node/xxx.com

USER node

WORKDIR /home/node/xxx.com

ENTRYPOINT ["/bin/bash", "-l", "-c", "./entry.sh"]

entry.sh

service nginx start
npm install
npm run watch &
compass watch

在我的笔记本电脑（Ubuntu 16.04）上启动。运行容器（使用-p 8000:80）一切都很好，但在我的Workstation（Ubuntu 14.10）上，nginx无法在容器内启动。如果我运行docker exec -it -u root <cid> /bin/bash然后service nginx start，一切都在运行。

如果不使用额外命令怎么办呢？为什么在我的笔记本电脑上而不是在我的工作站上工作？

顺便说一句：

也许你应该将你的nginx.sh文件复制到容器中并以shell脚本作为入口点启动容器？

将startskript添加到容器中
移动并设置为可执行文件

设置入口点以开始skript

FROM ubuntu：16.10

//add start script to temp
ADD run-nginx.sh  /tmp/

RUN useradd -m --password=node node && \
apt-get update && \
apt-get upgrade -y && \
apt-get install -y curl && \
apt-get install -y openssl 

&& \
  apt-get install -y nginx && \
  apt-get -qy autoremove

COPY . /home/node/xxx.com

RUN rm /etc/nginx/sites-enabled/default && \
  cd /etc/nginx/sites-enabled && \
  ln -s /home/node/xxx.com/xxx.nginx.conf default

WORKDIR /home/node

RUN curl -sL https://deb.nodesource.com/setup_7.x | bash - && \
  apt-get install -y nodejs 

RUN curl -L https://get.rvm.io | bash -s stable && \
  /bin/bash -l -c "rvm requirements" && \
  /bin/bash -l -c "rvm install 2.0" && \
  /bin/bash -l -c "gem update --system" && \
  /bin/bash -l -c "gem install bundler --no-ri --no-rdoc" && \
  /bin/bash -l -c "gem install compass  --no-ri --no-rdoc" && \
  /bin/bash -l -c "gem install bootstrap -v 4.0.0.alpha6 --no-ri --no-rdoc"

//copy to home and set to executable
RUN mv /tmp/run-nginx.sh / && chmod +x /run-nginx.sh

RUN chown -R node:node /home/node/xxx.com

USER node

WORKDIR /home/node/xxx.com

ENTRYPOINT ["/run-nginx.sh"]

docker-run nginx并非总是在工作
