name: Build & Push Docker Image

# Builds the Docker image and publishes it to the Gitea container registry
# at git.hackner.dev/thomas/rustdesk-api.
#
# Requires a running Gitea Actions runner (act_runner) and two repo secrets
# (Settings -> Actions -> Secrets):
#   REGISTRY_USER     - Gitea username (e.g. thomas)
#   REGISTRY_PASSWORD - a Gitea access token with "write:package" scope
#
# (Alternatively the built-in ${{ secrets.GITHUB_TOKEN }} can be used with
#  username ${{ gitea.actor }} if your Gitea grants it package write access.)
