docker - 在 docker 镜像中安装 sdkman

Question

安装时出错 SDKMAN!在 Ubuntu 16.04 docker 形象。

FROM ubuntu:16.04
RUN apt-get update
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN apt-get -qq -y install curl
RUN curl -s https://get.sdkman.io | bash
RUN chmod a+x "$HOME/.sdkman/bin/sdkman-init.sh"
RUN source "$HOME/.sdkman/bin/sdkman-init.sh"

TL;博士
安装 unzip & zip , 这意味着改变

RUN apt-get -qq -y install curl

至

RUN apt-get -qq -y install curl unzip zip

或更好

RUN apt-get -qq -y install \
    curl \
    unzip \
    zip

解释
当你尝试构建 Dockerfile 时，你会得到

    .....

    Step 5/6 : RUN curl -s https://get.sdkman.io | bash

    Now attempting installation...

    Looking for a previous installation of SDKMAN...
    Looking for unzip...
    Not found.

    Please install unzip on your system using your favourite package manager.

    Restart after installing unzip.

    The command '/bin/sh -c source "$HOME/.sdkman/bin/sdkman-init.sh"' returned a non-zero code: 1

你需要做的就写在那里。这部分:

    Please install unzip on your system using your favourite package manager.

    Restart after installing unzip.

安装 unzip 时，您会收到与 zip 相同的错误。安装后，一切正常。
因此，请阅读您的日志/命令输出。 :-)

*附注最好是 curl -s https://get.sdkman.io | bash以非零代码退出。这样它会在下一个命令上失败。但这不是您可以解决的问题 ;) *
