Thanks to the hint by Ali Amin I now have this working solution:

version: 2
jobs:
  build:
    machine: true
    steps:
      - run:
          name: Clone docs
          working_directory: ~/workdir
          command: |
            git clone --depth 1 https://${DOCS_GITHUB_TOKEN}@github.com/giantswarm/docs.git
      - deploy:
          name: Trigger docs deployment
          working_directory: ~/workdir/docs
          command: |
            git config credential.helper 'cache --timeout=120'
            git config user.email ""
            git config user.name "Deployment Bot"
            git commit --allow-empty -m "Trigger deployment"
            # Push quietly to prevent showing the token in log
            git push -q https://${DOCS_GITHUB_TOKEN}@github.com/giantswarm/docs.git master

Some notes:

• The git clone is first.
• All subsequent git commands have to be executed in the clone directory. working_directory simplifies this a great deal.
• The token DOCS_GITHUB_TOKEN is a personal access token with repo scope for the target repository.
