在ubantu映像中安装sdkman时出错。

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

从ubuntu：16.04 运行apt更新运行apt-get -qq -y install \ 卷曲解压压缩运行rm / bin / sh && ln -s / bin / bash / bin / sh 运行apt-get -qq -y install curl 运行curl -s https://get.sdkman.io |重击运行chmod a + x“ $ HOME / .sdkman / bin / sdkman-init.sh”

运行源“ $ HOME / .sdkman / bin / sdkman-init.sh”

Answer 2

安装unzip和zip，这意味着进行更改

RUN apt-get -qq -y install curl

到

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

或更佳

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

当您尝试构建Dockerfile时，您将获得

在安装解压缩文件时，您会看到与zip相同的错误，安装后一切正常。

因此，请阅读日志/命令输出。特别是在这里，它真的很明显：-）

P.S。如果curl -s https://get.sdkman.io | bash用非零代码退出会更好，在构建失败的地方更好地看到它。这样，它在下一个命令上将失败。但这不是您可以解决的。

看来sdkman安装失败。当我在上面运行您的代码时，它抱怨缺少unzip和zip软件包。

满足依赖性后，还需要使用以下命令将初始化脚本标记为可执行文件：

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

因此您的Dockerfile应该类似于：

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"

P.S：受到打击！
