节点JSdocker文件不正确的版本
我有一个简单的泊坞窗文件，拉节点图像，并创build一个容器，我们运行我们的应用程序。 请在我们的docker文件的第一行下面find。
FROM node:8 Other docker file commands to follow. 当我在容器中运行node --version command ，它显示版本为9.2.0，它是最新的节点版本。
我们的主机是运行Ubuntu的EC2
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
我们的Docker文件

我们从shell脚本内部构build映像，命令和输出如下

嗯 – 适用于我：
➜ ~ docker run node:8 node --version v8.9.3
我认为这是两件事情之一：
-
Dockerfile东西是升级节点 - 你没有在容器中运行
node --version，而是错误地在你的本地机器上运行它。
要么仔细检查你做的是正确的事情，并使用上面的命令，因为我有 – 或张贴完整的Dockerfile，让我们看看发生了什么事情。
这是来自最有可能的第二个，dockerfile中的重复FROMs或多或less被认为是一个错误，而不是Docker的一个特性，虽然它看起来像计划保留，因为它有一些有限的用例：
多个FROM – 意味着什么
keymetrics / pm2：最新可能在节点v8.9.3上
感谢您的澄清。 你是正确的，它是安装最新版本的Node JS的第二个。 我删除了另一个，并将其更改为
FROM keymetrics/pm2:8
现在一切都很好
