在docker容器中永远停止启动节点 [英] Error starting node with forever in docker container

问题描述

我有一个问题，当启动节点永远在docker容器，如果我启动手动工程，而是在Dockerfile中相同的命令，当构建和启动容器时，退出。
命令在bash中工作：

i have a problem when start node with forever in docker container, if i launch manually works, instead the same command in Dockerfile, when build and start the container, exited. The command works in bash:

docker run -it container_name bash forever start -c 'node --harmony' /my/path/app.js

我试图在Dockerfile中放置命令，但容器不开始

I tried to put command in Dockerfile but the container don't start

CMD forever start -c 'node --harmony' /my/path/app.js

永远启动script.js 在后台运行。要在前台运行 forever ，请尝试 forever script.js 。

Forever start script.js runs in the background. To run forever in the foreground, try forever script.js.

这是始终在前台，这是Docker需要的。只要在CMD中定义的进程启动并运行，记住一个容器是活着的。由于它永远是一个守护进程，所以命令本身退出并且docker也将退出。

This starts forever in the foreground, which is what Docker needs. Remember a container is "alive" only as long as the process defined in CMD is up and running. Since forever starts as a daemon, the command itself exits and docker will exit also.

CMD forever -c 'node --harmony' /my/path/app.js
