我有一个简单的docker文件，它可以提取节点图像并创建一个运行我们应用程序的容器。请在我们的docker文件的第一行下面找到。
uname -a
Linux ip.1.2.3.4-aws #50-Ubuntu SMP Wed Nov 15 22:18:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
当我在容器内运行FROM node:8.9.3
FROM keymetrics/pm2:latest
# Create app directory
RUN mkdir -p /usr/app/test/src
# Install app dependencies
COPY ./package.json /usr/app/test/
WORKDIR /usr/app/test
RUN npm install
# Move source files to the containter
COPY ./src/ /usr/app/test/src/
WORKDIR /usr/app/test/src
RUN pm2 install pm2-logrotate
RUN pm2 set pm2-logrotate:compress true
RUN pm2 set pm2-logrotate:retain 2
ARG NODE=production
ENV NODE_ENV ${NODE}
EXPOSE 443
#CMD [ "npm", "start" ]
CMD [ "pm2-docker", "start", "pm2.json" ]
时，它显示版本为9.2.0，这是最新的节点版本。
我们的主机是运行Ubuntu的EC2

答案 0 :(得分：0)
嗯 - 适合我：
➜ ~ docker run node:8 node --version
v8.9.3
我认为发生了两件事之一：
Dockerfile中的某些内容正在升级节点node --version，而是错误地在本地计算机上运行它。 要么仔细检查你做了正确的事情并使用上面的命令，就像我一样 - 或者发布你的完整Dockerfile并让我们看看发生了什么。
答案 1 :(得分：0)
它是最有可能的第二个，Docker文件中的重复FROM或多或少被认为是一个bug而不是Docker的一个功能部分，虽然它看起来像是计划保持原样一些有限的用例：
Multiple FROMs - what it means
keymetrics / pm2：最新版本可能在节点v8.9.3
上答案 2 :(得分：0)
感谢您的澄清。你是对的，它是第二个安装最新版本的Node JS的FROM。我删除了另一个FROM并将其更改为
{{1}}
现在一切都很好
