# Torrust Tracker Environment Configuration Script
|
|||
|
|
# Interactive configuration for tracker environments using TypeDialog + Nickel
|
|||
|
|
#
|
|||
|
|
# This script uses TypeDialog's nickel-roundtrip feature to:
|
|||
|
|
# 1. Load existing Nickel configuration (if exists)
|
|||
|
|
# 2. Launch interactive form with current values pre-populated
|
|||
|
|
# 3. Save updated configuration back to Nickel format
|
|||
|
|
# 4. Preserve validators and contracts in output
|
|||
|
|
#
|
|||
|
|
# Usage:
|
|||
|
|
# ./provisioning/scripts/configure.sh [cli|tui|web]
|
|||
|
|
#
|
|||
|
|
# Backend options:
|
|||
|
|
# cli - Command-line interface (simple prompts) [default]
|
|||
|
|
# tui - Terminal UI (interactive panels)
|
|||
|
|
# web - Web server (browser-based)
