我正在尝试在我的 Dockerfile 中以非根用户身份安装 ruby-build，但我收到了权限被拒绝的错误。如何授予部署用户执行此操作的权限？
错误
mkdir: cannot create directory `/usr/local/share/ruby-build': Permission denied

最佳答案
您正在尝试使用部署用户以根用户身份安装 ruby-build。 “作为独立程序安装(高级)”根据 here .
您可以尝试这样的操作(使用 sudo):
FROM centos:6.6
RUN yum update -y
RUN yum install git openssl-devel openssh-server sudo openssl readline-devel readline zlib-devel zlib libxml2-devel libxml2 libxslt-devel libxslt nginx tar gcc libaio libaio-devel -y
RUN rpm -Uvh https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-12.5.1-1.el6.x86_64.rpm
RUN sed -i -e "s/Defaults requiretty.*/ #Defaults requiretty/g" /etc/sudoers
RUN mkdir -p /var/run/sshd
# RUN adduser deploy -g wheel -p Password1
RUN useradd -m -u 1000 -G wheel deploy && echo '%wheel ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers.d/wheel
USER deploy
RUN git clone https://github.com/sstephenson/rbenv.git $HOME/.rbenv/
RUN git clone https://github.com/sstephenson/ruby-build.git $HOME/.rbenv/plugins/ruby-build
RUN sudo $HOME/.rbenv/plugins/ruby-build/install.sh
ENV PATH /home/deploy/.rbenv/bin:$PATH
RUN echo 'eval "$(rbenv init -)"' | sudo tee -a /etc/profile.d/rbenv.sh
RUN echo 'eval "$(rbenv init -)"' >> $HOME/.bashrc
RUN echo 'eval "$(rbenv init -)"' >> $HOME/.bash_profile
RUN source $HOME/.bash_profile
ENV CONFIGURE_OPTS --disable-install-doc
RUN rbenv install 2.2.3
RUN rbenv global 2.2.3
RUN bash -l -c 'gem update --system'
RUN bash -l -c 'gem update'
RUN bash -l -c 'gem install nokogiri -- --use-system-libraries'
RUN bash -l -c 'gem install bundler rails-api --no-rdoc --no-ri'
RUN touch /etc/sysconfig/network
