在docker镜像中安装sdkman

Question

安装时出现错误

在

docker镜像。

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"

Answer 1

确保你有curl，wget，unzip & zip。有了它们，我就能够成功地安装Sdkman。以下是我的Docker内容

FROM ubuntu:18.04

RUN apt-get update
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN apt-get -qq -y install curl wget unzip zip

RUN curl -s "https://get.sdkman.io" | bash
RUN source "$HOME/.sdkman/bin/sdkman-init.sh"

Answer 2

TL;DR

安装

&

，这意味着改变

RUN apt-get -qq -y install curl

至

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

或者更好

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

解释

当您尝试构建Dockerfile时，您将得到

.....

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

    Now attempting installation...

    Looking for unzip...

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

    Restart after installing unzip.

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，您会得到与zip相同的错误。安装后，一切工作正常。

因此，请阅读您的日志/命令输出。:-)

附言:如果你能做到这一点，那就更好了。

以非零代码退出。这样，它在下一条命令上就会失败。但这不是你可以解决的问题;)

Answer 3

它看起来像是

sdkman

安装失败。当我在上面运行您的代码时，它抱怨缺少

和

包。

在满足依赖关系之后，您还需要使用以下命令将init脚本标记为可执行：

chmod a+x "$HOME/.sdkman/bin/sdkman-init.sh"

所以你的Dockerfile应该看起来像这样：

FROM ubuntu:16.04
RUN apt-get update
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN apt-get -q -y install curl zip unzip
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"

附言:被打得落花流水！
