Dockerfile:试图安装ruby-build时拒绝的权限

Question

我试图在我的Dockerfile中将ruby构建作为一个非根程序安装，但是我得到了一个被拒绝的权限错误。我如何让部署的用户访问这样做？

错误

mkdir: cannot create directory `/usr/local/share/ruby-build': Permission denied

您正在尝试使用部署用户将ruby构建作为root安装。“安装作为一个独立的程序(高级)”，根据这里。

您可以尝试这样的方法(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'
