docker-compose命令在什么范围内运行

标签： docker docker-compose

我遇到了在docker compose文件中为我的容器运行启动脚本（例如npm run gulp-dist）的问题。我将问题归结为节点版本兼容性问题，这使我有些困惑。

如果我使用docker-compose run workspace bash输入容器，然后运行node -v，则会按预期（以及我的脚本要求）返回v10.5.0。 但是，如果在docker-compose中设置了command: node -v，则在用v4.2.6调出容器时会显示docker-compose up workspace。

所以我想知道其中是我在docker-compose中指定的运行命令（我以为它们一旦启动就在容器中运行）。以及如何在容器中运行命令-我想在docker-compose中指定该命令，因为我在两个不同的docker-compose文件（一个用于dev env，一个用于生产）中运行另一个命令。

注意：我的开发机的节点版本为11，所以我不知道四个节点在哪里。

此外，如果运行docker-compose run workspace bash然后运行原始脚本，则可以正常工作-作为docker-compose命令运行时，它只是失败。

这是我的dockerfile（对不起，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

仍然不知道命令在什么上下文中运行，但是使我的工作正常。这是由于通过NVM安装了节点。或者至少在我按照@Noogen的建议通过preg_*安装后，我可以对我的容器运行命令，并且它们可以访问正确的节点版本。我不得不选择一个较低的节点版本（不是我可以用NVM指定的10.5.0），但最终它起作用了，所以没有后顾之忧。
