Why don't files appear after gitlab ci/cd?

Question

ASP.NET

Used gitlab to deliver and deploy the project on Ubuntu. Wrote the following yml:

image: microsoft/dotnet:latest

stages:
    - publish

publish:
    stage: publish
    script:
        - "dotnet publish --configuration Release --output '/home/user/publish/test'"

GitLab indicated that everything was successful, but these files did not appear on the server. What could be the problem?
Here is the information about executing in git:

$ dotnet publish --configuration Release --output '/home/user/publish/test'

You called me. I'm not familiar with the dotnet ecosystem, but I'll assume that he builds the project and hosts it locally.
You do this in a docker container, it is hosted in a container, not on some server.
