# Unified Deploy Wrapper

# Auto-discovers deploy-{docker,local}-*.sh scripts in the same directory and
# dispatches to them with a shorter CLI interface.
#
# Usage:
#   deploy.sh                                  # List available services
#   deploy.sh mattermost                       # Deploy via docker (default)
#   deploy.sh -l paperclip                     # Deploy via local (bare-metal)
#   deploy.sh --local hermes --domain h.an2.io # Local deploy with flags
#   deploy.sh -r mattermost                    # --remove
#   deploy.sh -r -p mattermost                 # --remove --purge
#   deploy.sh -r -p -y mattermost              # --remove --purge --yes
#   deploy.sh web --domain w.an2.io --dir acme # Pass-through flags
