如何在docker中安装nvm? [英] How to install nvm in docker?

问题描述

我正在构建一个新的Docker映像，并且希望安装NVM，以便我可以管理nodejs.

I am in the process of building a new Docker image and I'm looking to get NVM installed so I can manage nodejs.

在阅读有关如何安装NVM的文档时，他们提到要开始使用NVM，您需要获取.bashrc文件的源代码.

Reading the docs on how to install NVM they mention that you need to source your .bashrc file in order to start using NVM.

我尝试在Dockerfile中进行设置，但到目前为止，构建失败并显示以下错误:

I've tried to set this up in a Dockerfile, but so far building fails with the error:

"bash:nvm:找不到命令"

"bash: nvm: command not found"

以下是我的Dockerfile中的相关行:

Here are the relevant lines from my Dockerfile:

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"

这是尝试构建的结果:

docker build -t nginx_dock

docker build -t nginx_dock .

我对Docker来说还很陌生，所以我可能缺少编写Dockerfile的基本知识，但是到目前为止，我所做的所有阅读都没有向我展示好的解决方案.

I'm pretty new to Docker so I may be missing something fundamental to writing Dockerfiles, but so far all the reading I've done hasn't shown me a good solution.

推荐答案

每次在单独的进程中运行RUN bash...时，环境中设置的任何内容均不会得到维护.这是我安装nvm的方法:

When you RUN bash... each time that runs in a separate process, anything set in the environment is not maintained. Here's how I install 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
