# gangway in its own VM: boot a stock Debian 13 or Ubuntu 24.04 cloud image with this as its
# user-data, and it installs Docker and gangway on first boot. Previews then run inside the VM,
# not beside everything else on the host.
#
# Pick how gangway is reached by editing GANGWAY_ARGS below (install.sh --help lists them all):
#   --lan                                    no domain; https://app.<vm-ip>.sslip.io:8443
#   --tls proxy --domain preview.example.com --listen :: --trusted-proxies <proxy-ip>/32
#                                            behind a reverse proxy on another machine
#   --tls acme --domain preview.example.com --cf-token <token>
#                                            gangway holds 80/443 on the VM's own address
#
