docker-compose命令在什么范围内运行

Posted 2021-04-18

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

和docker-compose的相关部分：

workspace:
    build:
      context: ./www-workspace
      args:
        - TZ=${WORKSPACE_TIMEZONE}
        - NODE_VERSION=${WORKSPACE_NODE_VERSION}
    command: [bash, -c, "cd /var/www/spa && npm run dist-prod"]

答案

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。
