Install sdkman in docker image

问题

Getting error while installing SDKMAN! in Ubuntu 16.04 docker image.

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"

回答1:

make sure you have curl, wget, unzip & zip. With them I am able to install Sdkman successfully. Following is my Docker content

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"

It looks like the sdkman install failed. When I ran your code above it complained about missing the unzip and zip packages.

After satisfying the dependencies, you'll also need to mark the init script as executable with:

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

So your Dockerfile should look something like:

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: Beaten to the punch!

TL;DR

Install unzip & zip, that means change

RUN apt-get -qq -y install curl

to

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

or better

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

Explenation

When you try to build the Dockerfile, you will get

    Now attempting installation...

    Looking for a previous installation of SDKMAN...
    Looking for unzip...

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

    Restart after installing unzip.

What you need to do is written just there. This part:

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

    Restart after installing unzip.

When you install unzip you get the same error with zip, after installing it, everything works fine.

So, read your logs/command output. Especially here it's really clearly visible :-)

*P.S. It would be definitely better if curl -s https://get.sdkman.io | bash exited with non-zero code. This way it fails on the next command. But that is not a thing you can fix ;) *
