如何在Docker中安装nvm？

Question

我正在构建一个新的Docker映像，我希望安装NVM，这样我就可以管理NodeJ了。

阅读关于如何安装NVM的文档时，他们提到，为了开始使用NVM，您需要提供.bashrc文件的源码。

ADD files/nvm_install.sh /root/
RUN chmod a+x  /root/nvm_install.sh
RUN bash -c "/root/nvm_install.sh"
RUN bash -l -c "source /root/.bashrc"
RUN cd /root
RUN bash -l -c "nvm install 0.10.31"

当每次运行在单独进程中的bash...时，环境中设置的任何内容都不会得到维护。以下是我如何安装NVM:

# Replace shell with bash so we can source files
RUN rm /bin/sh && ln -s /bin/bash /bin/sh

# Set debconf to run non-interactively
RUN echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections

# Install base dependencies
RUN apt-get update && apt-get install -y -q --no-install-recommends \
        apt-transport-https \
        build-essential \
        ca-certificates \
        curl \
        git \
        libssl-dev \
        wget \
    && rm -rf /var/lib/apt/lists/*

ENV NVM_DIR /usr/local/nvm # or ~/.nvm , depending
ENV NODE_VERSION 0.10.33

# Install nvm with node and npm
RUN curl https://raw.githubusercontent.com/creationix/nvm/v0.20.0/install.sh | bash \
    && . $NVM_DIR/nvm.sh \
    && nvm install $NODE_VERSION \
    && nvm alias default $NODE_VERSION \
    && nvm use default

ENV NODE_PATH $NVM_DIR/v$NODE_VERSION/lib/node_modules
ENV PATH      $NVM_DIR/v$NODE_VERSION/bin:$PATH
