Anso 2d9e4d0480 fix(mesh): derive override services from compose file and surface cross-node dispatch (#1017)
* fix(mesh): derive override services from compose file and surface cross-node dispatch

Three fixes for issues found during Phase B end-to-end verification:

1. Override generator no longer queries Dockerode for services. Deploys
   removed all containers in the project right before composeArgs ran,
   so docker.listContainers({label: project=...}) returned [] and the
   generator wrote services: {} which broke meshed user containers.
   New helper getDeclaredStackServiceNames reads the local stack's
   compose file via FileSystemService + YAML.parse and returns the
   top-level services keys. Used from ensureStackOverride and
   applyLocalOverride. Defensive fallback: when the read returns []
   AND a previous override on disk has a non-empty services map,
   keep the file and emit mesh.override.preserved.

2. Boot regen race against the pilot tunnel. regenerateAllOverrides
   ran ~1s before the first pilot tunnel-up event, so pushes to
   pilot-mode nodes failed with "no proxy target". MeshService.start
   now also runs regenerateOverridesForNode(nodeId) inside the
   tunnel-up listener, covering both the boot-race window and
   mid-runtime tunnel reconnects. Idempotent.

3. openCrossNode emitted no activity log when a cross-node dial got
   stuck waiting for tcp_open_ack. The forwarder accepted the TCP
   handshake (so nc -v reported open) but logged nothing between
   accept and close. Now logs route.dispatch on entry and emits
   tunnel.fail after PROBE_TIMEOUT_MS if the agent never acks.
   Timer is cleared on every tcpStream and src lifecycle event.

Tests: 8 new in mesh-service.test.ts cover the helper, the BUG-1
override write path, the defensive preservation fallback, the
tunnel-up regen handler, and both cross-node dispatch logging
behaviors. Full vitest suite green (1998 tests pass).

* fix(mesh): satisfy CodeQL path-injection model in new override-read paths

Two new fs.readFile sites added in the previous commit failed the
CodeQL check on the PR even though both paths were guarded by
isValidStackName + isPathWithinBase. The file's existing
applyLocalOverride pattern uses path.basename(stackName) before the
join (commented as "Recognized by CodeQL's path-injection model");
apply the same sanitizer to the new code paths.

- getDeclaredStackServiceNames: wrap stackName in path.basename when
  building composePath.
- readExistingOverrideServiceNames: take (dir, stackName) instead of
  a pre-built filePath so the sanitizer lives next to the read sink.
- ensureStackOverride: build the override file path with
  path.basename(stackName) for symmetry with applyLocalOverride.

Runtime behavior unchanged (path.basename is a no-op for any name
that passed isValidStackName). Tests still green.

Sencho dashboard

What Sencho is

Sencho is for homelab operators, small DevOps teams, and platform engineers who run services on Docker Compose, want a graphical interface without giving up file-on-disk workflows, and need to manage more than one machine without SSH gymnastics or a VPN.

It runs as a single container on your hardware and gives you a UI for the work you currently do over SSH on compose stacks: deploying, editing files, watching logs, restarting containers, browsing volumes, and recovering from failures. Your compose files stay on the host filesystem and remain the source of truth.

A Sencho instance is autonomous. To manage another machine, you install a second Sencho on it and connect them with a long-lived API token; the primary dashboard then acts as a transparent HTTPS proxy across your fleet. There is no SSH and no exposed Docker socket. For nodes behind NAT or strict firewalls, the Pilot Agent establishes a single outbound WebSocket tunnel to the primary, so the remote host opens no inbound port at all.

Most capabilities are free in the Community tier. A few advanced automation and fleet-control features ship in paid tiers; pricing lives at sencho.io/pricing.


Capabilities

Stacks

  • Full Compose lifecycle: create, deploy, restart, stop, pull
  • Monaco editor with diff preview before save and one-click rollback
  • Git-sourced stacks pulled and synced from any repository
  • File explorer for compose, env, and supporting files
  • Stack labels for grouping and bulk operations
  • App Store with LinuxServer.io templates

Observability

  • Aggregated log search and stream across every container in the fleet
  • Live container stats, health checks, and image-update notifications
  • Threshold alerts for CPU, memory, and network
  • Read-only audit log of every action
  • Network topology view of containers, networks, and nodes

Fleet

  • Multi-node management via authenticated HTTP and WebSocket proxy
  • Fleet view with grid and topology layouts
  • Fleet snapshots of compose and env across the fleet
  • Pilot Agent for nodes behind NAT or strict firewalls
  • Node compatibility checks before deploying

Quick start

Sencho runs in a single container.

services:
  sencho:
    image: saelix/sencho:latest
    container_name: sencho
    restart: unless-stopped
    ports:
      - "1852:1852"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./data:/app/data
      # 1:1 Compose Path Rule: the host path MUST match the container path
      - /opt/docker:/opt/docker
    environment:
      - COMPOSE_DIR=/opt/docker
      - DATA_DIR=/app/data
docker compose up -d

Open http://your-server:1852 and create your admin account.

Always front Sencho with a TLS-terminating reverse proxy in production. See the self-hosting guide for hardening, environment variables, and reverse-proxy examples.

Run with docker run instead
docker run -d --name sencho \
  -p 1852:1852 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v sencho_data:/app/data \
  -e COMPOSE_DIR=/opt/docker \
  saelix/sencho:latest

For the full walkthrough, see the quickstart guide.


Adding remote nodes

To manage a second machine, install Sencho on it the same way, then add it from the primary dashboard with its URL and a long-lived API token. The primary proxies authenticated HTTPS and WebSocket requests to the remote instance. No SSH, no exposed Docker socket, no agent process on the remote. Nodes behind NAT or strict firewalls can opt into the Pilot Agent for outbound-only connectivity.

See the multi-node guide for the full token-bearer flow.
