in what scope are docker-compose commands run - docker

Question

I am hitting issues running a start script (eg npm run gulp-dist) for my container as specified in my docker compose file. I traced the issue down to a node version compatibility issue which has led me to some confusion.
If I enter the container with docker-compose run workspace bash and then run node -v I get back v10.5.0 as expected (and what my script requires).
Yet if in docker-compose I set command: node -v it prints v4.2.6 when bringing up the container with docker-compose up workspace.
So I'm wondering where are the commands run that I specify in docker-compose (I thought they were run in the container once it had started). And how do I run a command in the container - I want to specify it in docker-compose as I run a different command in two different docker-compose files (one for dev env, one for production).
Note: My dev machine has node version 11, so I have no idea where four is.
Also, if run docker-compose run workspace bash and then run the original script, it works fine - it is just failing when run as a docker-compose command.
Here's my dockerfile (sorry, it's big):
# FROM laradock/workspace:1.8-71
# copied the contents of the above laradock workspace
# dockerfile and replaced put here directly.
FROM phusion/baseimage:latest

Still don't know what context the commands run in, but made mine work. It was due to node being installed via NVM. Or at least when I installed, as #Noogen suggested, via curl -sL https://deb.nodesource.com/setup_10.x | sudo bash - I could then run commands against my container and they would have access to the correct node version. I had to settled for a lower node version (not 10.5.0 as I could specify with NVM) but in the end it worked so no worries.
