将Dockerfile编译为镜像

docker build -f Dockerfile的路径 -t 镜像名:tag

遇到的问题

1. Dockerfile交互问题

• 如果是apt安装场合，使用-y 参数解决
  RUN apt-get install -y xxx

• 安装脚本场合
  比如我们用sh Anaconda3-2019.07-Linux-x86_64.sh来安装anaconda的时候，”烦人”的anaconda会问四个问题，我的回答顺序分别是Enter，yes，Enter，yes。于是你可以这样写：
  RUN sh -c '/bin/echo -e "\nyes\n\nyes" | sh Anaconda3-2019.07-Linux-x86_64.sh'

• Dockerfile中安装tzdata交互场合

  # 设置环境变量
  ENV DEBIAN_FRONTEND noninteractive # 非交互模式
  ENV TIME_ZONE Asia/Shanghai # 目标时区
  
  # 安装tzdata软件包（默认：Etc/UTC）
  RUN apt-get install -y tzdata 
  
  # 建立到期望的时区的链接(ubuntu16.04以上需要)，并且修改/etc/timezone
  RUN ln -snf /usr/share/zoneinfo/$TIME_ZONE /etc/localtime && echo $TIME_ZONE > /etc/timezone
  
  # 重新配置tzdata软件包，使得时区设置生效
  RUN dpkg-reconfigure --frontend $DEBIAN_FRONTEND tzdata
  

2. 对【每条指令都是在一个新的容器中执行】的理解

• 以下指令报错，/bin/sh: 1: ./configure: not found

  WORKDIR /opt/Python-3.7.4
  RUN ./configure
  RUN make
  RUN make install
  

  是因为，在执行RUN ./configure指令时，已经在一个新的容器中了，而在新的容器中没有进入到/opt/Python-3.7.4目录，自然找不到configure

• 解决方法
  将指令写成一条指令即可RUN cd /opt/Python-3.7.4 && ./configure && make && make install

3. Dockerfile中加入ENTRYPOINT指令，镜像能build成功，但是不能run起来

原因还没有找到，希望大神看到了告知
