Selenium + Docker

Hi everybody!
I need a help, comrades!
I have this conteiners (installed):
selenium/node-firefox
selenium/node-chrome
selenium/node-firefox-debug
selenium/node-chrome-debug
selenium/hub
Started the HUB and NODEs:
# docker run -d -p 4444:4444 –-name selenium-hub selenium/hub
# docker run -d -–link selenium-hub:hub selenium/node-chrome
# docker run -d -–link selenium-hub:hub selenium/node-firefox
then started "debug":
# docker run -d –P –-link selenium-hub:hub selenium/node-chrome-debug
# docker run -d –P –-link selenium-hub:hub selenium/node-firefox-debug
On the server no GUI (and never be). Testing on the 1 server (localhost). Im googling and googling few weeks - how i have to run some test scripts on my nodes (without GUI)?

I'm sorry, but I don't understand it. Probably you need to explain better that situation.

Ok) I have selenium/hub where i installed nightwather. I have a simple test-script .js. Then –-link selenium-hub with node-chrome, start selenium grid - all Ok, BUT i don't understand how i have to send test-script on the my node.
This is my nightwatch.json on the Docker selenium/hub:
