【问题描述】：

我正在将节点应用程序部署到 aws eb，这是我的 Dockerfile

FROM    ubuntu:14.04

RUN rm /bin/sh && ln -s /bin/bash /bin/sh

# Install base packages
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y \
    zsh \
    vim \
    git \
    curl \
    build-essential \
    nodejs \
    npm \
    supervisor

RUN update-alternatives --install /usr/bin/node node /usr/bin/nodejs 10

RUN mkdir -p /var/run/sshd /var/log/supervisor

COPY build/supervisord.conf /etc/supervisor/conf.d/supervisord.conf

RUN mkdir -p /app
ADD api/ /app

RUN cd /app && npm install

WORKDIR /app

EXPOSE 8090

CMD ["/usr/bin/supervisord"]

这是我的supervisord.conf

[supervisord]
nodaemon=true

[program:nodejs]
directory=/app
command=node server.js web
autorestart = true
stdout_logfile=/var/log/%(program_name)s.log
stderr_logfile=/var/log/%(program_name)s.log

这是我的stdouterr.log

此时任何建议都会有所帮助。

【问题讨论】：

您的节点应用程序崩溃了吗？请尝试使用最小的节点应用程序。还可以尝试从节点打印到标准输出以调试内部出了什么问题。

你说得对，@AssafLavie 我的节点应用程序崩溃了，因为我的节点和 npm 版本没有设置正确。

【参考方案1】：

正如 cmets 中的 @AssafLavie 所说，节点应用程序崩溃了。它崩溃的原因是因为我必须将node 和npm 版本设置为我的package.json 文件中的指定版本。

我的Dockerfile 现在看起来像

# Install base packages

    npm \
    supervisor
