# ------------------------------------------------------------------
# INACTIVE BY DEFAULT -- manual trigger only (workflow_dispatch).
#
# This workflow builds and publishes a multi-architecture Docker image
# (linux/amd64 + linux/arm64) to Docker Hub.
#
# TO ACTIVATE:
#   1. Add two repository secrets (Settings > Secrets and variables > Actions):
#        DOCKERHUB_USERNAME  - your Docker Hub username
#        DOCKERHUB_TOKEN     - a Docker Hub access token (not your password)
#   2. Optionally add automatic triggers by uncommenting the lines below:
#        push:
#          branches: [master]
#          paths: ['VMs/Dockerfile']
#        release:
#          types: [published]
#
# Until you do both steps, this workflow does nothing on its own.
