無法在docker映像中使用sdkman安裝groovy

Question

我使用腳本來構建dockerfile。下面是我的腳本...

echo "FROM ubuntu:14.04" >> Dockerfile 
echo "RUN rm /bin/sh && ln -s /bin/bash /bin/sh" >> Dockerfile 
echo "RUN apt-get -y update && apt-get upgrade -y" >> Dockerfile 
echo "RUN apt-get install -y software-properties-common" >> Dockerfile 
echo "RUN apt-get -y update && add-apt-repository -y ppa:webupd8team/java" >> Dockerfile 
echo "RUN echo debconf shared/accepted-oracle-license-v1-1 select true | debconf-set-selections" >> Dockerfile 
echo "RUN echo debconf shared/accepted-oracle-license-v1-1 seen true | debconf-set-selections" >> Dockerfile 
echo "RUN apt-get -y update && apt-get install -y oracle-java8-installer" >> Dockerfile 
echo "RUN apt-get install -y curl " >> Dockerfile 
echo "RUN apt-get install -y unzip " >> Dockerfile 
echo "RUN apt-get -y update && curl -s get.sdkman.io | bash" >> Dockerfile 
echo 'RUN source "$HOME/.sdkman/bin/sdkman-init.sh"' >> Dockerfile 
echo 'RUN source ~/.profile' >> Dockerfile 
echo "RUN yes | sdk install groovy" >> Dockerfile 
... 
docker build -t imagename:version ./ 
... 

，但我得到下面的錯誤

RUN yes | sdk install groovy 
---> Running in 09056add5ab7 
/bin/sh: sdk: command not found 
The command '/bin/sh -c yes | sdk install groovy' returned a non-zero code: 127 

，如果我不使用此命令 「SDK安裝常規」 的構建是sucessfull。然後我運行圖像併發出相同的命令，它的工作原理。

任何幫助，任何想法，爲什麼這是頭痛？

Answer 1

RUN yes | /bin/bash -l -c 'sdk install groovy' 

工作。
