docker - 使用Dockerfile运行命令时出错

Question

我正在尝试使用this tutorial将rbenv安装在centos容器中。
当我自己在bash中运行这些命令时，它们可以工作，但是当使用docker build时，出现以下错误。

FROM centos:latest

RUN yum install -y sudo git vim git-core zlib zlib-devel gcc-c++ patch readline readline-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison curl sqlite-devel

RUN cd
RUN git clone git://github.com/sstephenson/rbenv.git .rbenv
RUN echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
RUN echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
RUN exec $SHELL

RUN git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
RUN echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
RUN exec $SHELL
RUN source ~/.bash_profile

RUN rbenv install -v 2.2.1
RUN rbenv global 2.2.1

RUN echo "gem: --no-document" > ~/.gemrc

RUN gem install bundler

输出

Step 9 : RUN exec $SHELL

Step 10 : RUN source ~/.bash_profile

The command '/bin/sh -c rbenv install -v 2.2.1' returned a non-zero code: 127

我究竟做错了什么？

您的源命令在RUN中，因此在下一个命令中将其忘记
