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

  1. 如果是apt安装场合，使用-y 参数解决

    1
    RUN apt-get install -y xxx

  2. 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：

    1
    RUN sh -c '/bin/echo -e "\nyes\n\nyes" | sh Anaconda3-2019.07-Linux-x86_64.sh'

  3. 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

    1
    2
    3
    4
    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
