Duplicate part of gitlab repository to another repository inside gitlab

Question

I have a Shared Server running IIS that accepts Git automatic deployment, I am using .Net 2.2. Files will be deployed to the plesk website as soon as they are pushed to the gitlab repository using SSH and WebHooks. So this repository will only have deployed, e.g: dll files. I have another repository for the repository in gitlab.

I am able to publish locally by the command bellow in pipeline.

 publish-to-dev:
  stage: publish-to-dev
  image: mcr.microsoft.com/dotnet/sdk:3.1-focal
  script:
    - 'dotnet publish -c Release'

Question: How can I create a pipeline command that will copy the deployed files from the code repository to the deployment repository after the deployment command dotnet publish?

EDIT

Question was answered by Mike bellow, but I am getting an error on the process of copying file, I am getting the message like bellow:

$ cp artifacts/emaua/* deploy/
cp: -r not specified; omitting directory 'artifacts/emaua/cs'
cp: -r not specified; omitting directory 'artifacts/emaua/de'

Solved by adding -r like - 'cp -r path/to/published/files/* deploy/'

Use GitLab Artifacts

The dotnet publish command will build the project and then put the output files to a folder on the build system.

This will be a folder on the GitLab Runner machine that's running the publish-to-dev job.

If you want to be able to download the published files from GitLab, then you can use artifacts to specify that the directory containing the published files be zipped up and attached to the job after it completes.

 publish-to-dev:
  stage: publish-to-dev
  image: mcr.microsoft.com/dotnet/sdk:3.1-focal
  script:
    - 'dotnet publish -c Release'
  artifacts:
    paths:
      - path/to/published/files/

The files will be available as artifacts.zip on the job (on the right-hand side bar).

Caveats:

This doesn't actually put the published files into the deployment repository. To do that you would have to download the ZIP and then add it to the repo yourself.

Use git inside your job

Alternatively, since you want to push these to the other repository, then things get more tricky. You need to do these things:

• Get an access token for the deployment repository
• Store this in a pipeline variable for the code repository - in my example below, it's called DEPLOY_REPO_TOKEN
• Retrieve the token in your job (using variables), and use it to authenticate when you do git operations to the deployment repository
• In the publish-to-dev job, git clone the deployment repository (using the token), git add the published files, and then git push, something like this:

 variables:
  DEPLOY_REPO_TOKEN: $DEPLOY_REPO_TOKEN
  DEPLOY_REPO_URL: 'gitlab.example.com/group/project/deployment-repository'
 publish-to-dev:
  stage: publish-to-dev
  image: mcr.microsoft.com/dotnet/sdk:3.1-focal
  script:
    - 'dotnet publish -c Release'
    - `git clone https://oauth2:$DEPLOY_REPO_TOKEN@$DEPLOY_REPO_URL.git deploy'
    - 'cp -r path/to/published/files/* deploy/'
    - 'cd deploy'
    - 'git add .'
    - 'git commit -m "deployed"'
    - 'git push'

Caveats:

• I haven't looked ino the mcr.microsoft.com/dotnet/sdk:3.1-focal image to see if this is dotnet on a Linux (so that the cp command will work), or if it's a Windows image (requiring copy instead, and different path separators).
• Also the image would require the git command to be present, or else you'll have to install that first.
