How to organize an auto-deploy?

Question

Software Deployment

What is the name of what I need?
There is a repository on gitlab/github with the project.
There is a server on which it is required to start the project.
I make a key to access my server, give it to gitlab.
As soon as I commit to the repository, the gitlab/github service enters my server and runs the script I specified.
How does is called? Which tool on github/github is responsible for this?
Thanks
