我正在使用我的docker compose文件中指定的容器运行启动脚本（例如npm run gulp-dist）的问题。我将问题追溯到节点版本兼容性问题，这让我有些困惑。
如果我使用docker-compose run workspace bash输入容器然后运行node -v我会按预期返回v10.5.0（以及我的脚本需要的内容）。然而，如果在docker-compose中设置command: node -v，它会在用v4.2.6打开容器时打印docker-compose up workspace。
所以我想知道我在docker-compose中指定的命令运行在哪里（我认为它们一旦启动就在容器中运行）。我如何在容器中运行命令 - 我想在docker-compose中指定它，因为我在两个不同的docker-compose文件中运行不同的命令（一个用于dev env，一个用于生产）。
注意：我的开发机器有节点版本11，所以我不知道四是哪个。
此外，如果运行docker-compose run workspace bash然后运行原始脚本，它运行正常 - 它只是作为docker-compose命令运行时失败。
这是我的dockerfile（对不起，它很大）：
# FROM laradock/workspace:1.8-71
# copied the contents of the above laradock workspace
# dockerfile and replaced put here directly.
FROM phusion/baseimage:latest

仍然不知道命令运行的上下文，但使我的工作。这是由于节点是通过NVM安装的。或者至少在我安装时，正如@Noogen建议的那样，通过curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -我可以对我的容器运行命令，他们可以访问正确的节点版本。我不得不选择较低的节点版本（不是10.5.0，因为我可以用NVM指定），但最终它的工作没有后顾之忧。
