Example Workflow

# 1. Create app from dashboard template
slforge create mydashboard --from-template dashboard

# 2. Start the app

LuCI Interface

Install luci-app-streamlit-forge for web interface at Services > Streamlit Forge.

Features:

• Status dashboard (running/total apps, LXC status)
• Create app dialog with template selection
• App table with Start/Stop/Open/Expose/Publish/Delete
• Auto-refresh polling

Runtime

Apps run inside the streamlit LXC container:

• Apps mounted at /srv/apps/ inside container
• Python virtualenv with Streamlit pre-installed
• Port forwarding to host network

Dependencies

• python3, python3-pip
• lxc, lxc-common
• jsonfilter

File Locations

Path	Description
/etc/config/streamlit-forge	UCI configuration
/usr/sbin/slforge	CLI tool
/srv/streamlit/apps/	App source directories
/srv/streamlit/previews/	Generated previews
/usr/share/streamlit-forge/templates/	App templates
/var/run/streamlit-*.pid	PID files
/var/log/streamlit-*.log	App logs

Mesh Catalog Manifest

Published apps create a manifest at /usr/share/secubox/plugins/catalog/:

{
  "id": "streamlit-myapp",
  "name": "myapp",
  "type": "streamlit-app",
  "version": "1.0.0",
  "category": "apps",
  "runtime": "streamlit",
  "actions": {
    "start": "slforge start myapp",
    "stop": "slforge stop myapp"
  }
}

On-Demand Launcher

Install secubox-app-streamlit-launcher for resource optimization:

• Lazy Loading - Apps start only when first accessed
• Idle Shutdown - Stop apps after configurable timeout (default: 30 min)
• Memory Management - Force-stop low-priority apps when memory is low
• Priority System - Keep critical apps running longer

Launcher Commands

# Check launcher status
slforge launcher status

# Set app priority (higher = keep running longer, max 100)
slforge launcher priority myapp 75

# Mark app as always-on (never auto-stopped)
slforge launcher always-on dashboard

Priority Levels

Priority	Behavior
100 + always_on	Never auto-stopped
80-99	Stopped last during memory pressure
50 (default)	Normal priority
1-49	Stopped first during memory pressure

How It Works

1. User accesses https://app.example.com
2. If app is stopped, launcher starts it on-demand
3. App access time is tracked
4. After idle timeout, app is automatically stopped
5. Memory pressure triggers low-priority app shutdown
