triton-install/manage-server/install.sh

#!/usr/bin/env bash
# install.sh — Triton Manage Server installer.
#
# Idempotent. Generates secrets on first run, reuses .env afterwards.
# Container-based via Podman or Docker (auto-detected).
#
# Usage:
#   sudo bash install.sh --license-file /path/to/bundle/license.lic
#
# The license bundle (provided by your vendor) is a single file:
#   license.lic   — signed offline licence token
# The vendor's public key is baked into the image at build time.
#
# Flags:
#   --license-file PATH             Path to license.lic from your vendor bundle. Required.
#   --gateway-hostname HOST         Agent mTLS hostname (defaults to current FQDN).
#   --manage-host-ip IP             Host LAN IP — used for "+ This machine".
#   --port PORT                     Host port for the web UI (default: 8082).
#   --image TAG                     Pin a specific manage-server image tag.
#   --no-tls                        Skip the TLS-required sanity check (dev).
