Node.js-了解和限制内存使用

Question

I am in the process of running multiple Node applications on a single instance. One of the elements I am concerned about is memory usage. Is there a minimum amount of physical memory required by a simple Node.js express service? Is there a way I can set an upper bound on the memory usage to prevent one of my node applications from affecting the others use of physical memory?

Answer 1

It might be worth your while to put your node processes on docker instance. Might just start with the default node docker image and then add your source code and boot up the scripts in the Dockerfile.

Docker allows you to limit the memory of each Docker instance, and many Docker instances can run on a single machine (or Virtual Machine). I think this approach might be your best bet.
