pm2 和 pm2-runtime 的区别

• pm2-runtime designed for Docker container which keeps an application in the foreground which keep the container running.
• pm2 is designed for normal usage where you send or run the application in the background.

例子：

Dockerfile

FROM node:alpine
RUN npm install pm2 -g
COPY . /app
WORKDIR /app
CMD [ "pm2", "start","/app/server.js"]

这种情况容器会在刚启动的时候就挂掉。

为了解决这个问题，可以使用 pm2-runtime

FROM node:alpine
RUN npm install pm2 -g
COPY . /app
WORKDIR /app
ENV NODE_ENV=development
CMD [ "pm2-runtime", "start","/app/bin/www"]
