Anso 4003e7c047 fix(fleet): capture local self-update helper errors (#495)
The helper container that runs `docker compose up --force-recreate` was
spawned with `docker run -d`, so the command returned immediately with
just the container ID. Any failure happening INSIDE the helper (bad
compose file, image mismatch, permission issue, socket problem) was
invisible: execFile's callback only fired for `docker run` command
errors, never for errors inside the detached helper. The UI fell back to
the generic 3-minute "Local update did not complete" heuristic with no
actionable information.

The helper now runs attached, so execFile's callback receives the
helper's exit code and stderr directly for any failure that happens
before the recreate kills this process. Additionally, the helper
persists exit code + stderr to `/app/data/.sencho-update-error` before
exiting, so the error survives the gateway's own death. On startup,
`SelfUpdateService.recoverPreviousError()` reads and deletes that file,
routing the real error through the existing `getLastError()` path so the
freshly booted gateway reports exactly why the previous attempt failed
instead of the generic timeout.

Sencho

CI Docker License

A self-hosted Docker Compose management dashboard. Manage your stacks, containers, images, volumes, and networks through a modern web UI.

Sencho Dashboard

Features

  • Stack Management - Create, edit, start, stop, and remove Docker Compose stacks with a built-in Monaco code editor
  • Multi-Node Support - Manage remote Sencho instances through a transparent HTTP/WebSocket proxy (Distributed API model)
  • App Store - One-click deployment from LinuxServer.io templates with editable ports, volumes, and environment variables
  • Resource Hub - Browse and manage images, volumes, and networks with managed/external/unused classification
  • Live Logs - Aggregated real-time log streaming across all containers with search and filtering
  • Dashboard - Container stats, CPU/RAM metrics, health checks, and image update notifications
  • Alerts - Configurable threshold alerts for CPU, RAM, and disk usage
  • Terminal - In-browser host console and container exec via WebSocket

Quick Start

services:
  sencho:
    image: saelix/sencho:latest
    container_name: sencho
    restart: unless-stopped
    ports:
      - "3000:3000"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/app/data
      # 1:1 Compose Path Rule: host path MUST match container path
      - /opt/docker:/opt/docker
    environment:
      - COMPOSE_DIR=/opt/docker
      - DATA_DIR=/app/data
docker compose up -d

Then open http://your-server:3000 and create your admin account.

See the full documentation for configuration details, multi-node setup, and more.

Development

# Backend (Express + TypeScript)
cd backend && npm install && npm run dev

# Frontend (React + Vite)
cd frontend && npm install && npm run dev

The frontend dev server proxies /api requests to the backend on port 3000.
