What I have done in the past is have my entrypoint defined in the Dockerfile be a shell script and then run the node command from within that script.

So in my Dockerfile I have this -

ENTRYPOINT ["./docker-start.sh"]

And my docker-start.sh script contains this:

#! /bin/bash

# Initialization logic can go here

echo "Starting node..."
node start.js $* # The $* allows me to pass command line arguments that were passed to the docker run command. 

# Cleanup logic can go here
