node.js - How to shut down a node server with a shell script?

Question

The context of this question is that I am setting up a CI/CD pipeline in AWS. I'm currently at the stage where I am creating the appspec.yml file which instructs the AWS robots on where to put my files from my new build onto my EC2 instance, as well as a list of .sh files with bash commands to stop the server, install dependencies and start the server again.

Well right off the bat I have hit a wall here. The method to shut down a node server is ctrl+c. However I have no idea how to successfully put that into bash script. And considering how many people have CI/CD pipelines setup with node servers, i'm shocked that I haven't been able to find a sample script file for this already. Does anyone have any resources on this?

Answer 1

Use the command kill (or it's variations like pkill) to send a signal to the server process and shut it down.

kill requires the pid of the process whereas pkill requires the name of the process
