How to run multiple instances of the same test with different data

[jesxs]

I have a test which simulates an user logging in and performing some actions.
I need to test the load on the server with a higher quantity of users so I need to be able to run parallel instances of the same test, but I need to let each test know what user credentials to take so everyone is a different user.
Im using chromedriver.

I was looking into docker but I'm not sure if this is the best approach.

I'd appreciate any idea or suggestion.

Thanks in advance
