在docker镜像中安装sdkman

安装 unzip 和; zip ,这意味着改变

RUN apt-get -qq -y install curl

到

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

或更好

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

当您尝试构建dockerfile时,您将得到

    .....

    Step 5/6 : RUN curl -s https://get.sdkman.io | bash
    ---> Running in 1ce678a59561

    Now attempting installation...

    Looking for unzip...

当你安装解压,你得到相同的错误与ZIP,安装后,一切正常。

所以,请阅读日志/命令输出。尤其是在这里,它真的很明显:-)

P.S.如果 curl -s https://get.sdkman.io | bash 使用非零代码退出时,在生成失败的地方更容易看到它。这样下一个命令就失败了。但那不是你能解决的。

看起来像是 sdkman 安装失败。 当我在上面运行你的代码时,它抱怨缺少 unzip 和 zip 包装。

在满足依赖关系之后,还需要将init脚本标记为可执行:

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

所以你的档案应该看起来像:

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"

警察:被揍了一顿!
