How to change deployment url for github pages action

[willeppy]

I am building a site for my repo using a github actions workflow. To deploy the website, I run the below action. How can I change the url where this site is deployed?

Specifically, I would like to add a route to the end so that instead of deploying to example.com/project it deploys to example.com/project/notebook. It seems to be set by ${{steps.deployment.outputs.page_url}}. I tried adding notebook to the end of this like ${{steps.deployment.outputs.page_url}}notebook with no luck.

Here is my deploy action that runs after build in the yaml:

 deploy:
    needs: build
    if: github.ref == 'refs/heads/main'
    permissions:
      pages: write
      id-token: write

    environment:
      name: github-pages
      url: ${{steps.deployment.outputs.page_url}} # How can i change this url??

    runs-on: ubuntu-latest
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v1

@willeppy According to action source code, you cannot change page_url output for now.
It's composed from GitHub API response for your repository and has no inputs (variables) modificators (hardcoded).

Of course, you can alter this value, adding additional step to deploy job:

...
    environment:
      name: github-pages
      url: ${{ steps.change-page-url.outputs.new_page_url }}

    runs-on: ubuntu-latest
    steps:
      - name: Deploy docs to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v1
      - name: Override page_url
        id: change-page-url
        run: echo "new_page_url=${{ steps.deployment.outputs.page_url }}notebook/" >> $GITHUB_OUTPUT
...

But this option will only affect (change) URL for job output, for example:

All deploy will be done for your repository Pages URL (<user>.github.io/<repo_name>/) which is not configured in v1.
Even "preview" functionality in alpha now, without any words how to use it. We can only wait when developers add this feature and this input parameter for changing result page_url or describe how to use preview input.

For quick response (new version), I think you should create an issue (with feature request) in action's repo:

Thanks for the info! I figured it might not be possible at the moment but was curious if there were work arounds. I filed an issue in the repo you suggested for tracking actions/deploy-pages#73
