Anso c9452337e1 test(pilot): in-process simulation of mid-tunnel disconnects (#987)
* test(pilot): in-process simulation of mid-tunnel disconnects

The PR #979 hardening added per-stream idle timers, drain handling,
paused-request maps, and a tcpAwaitingDrain set on the bridge. None
of those cleanup paths had an end-to-end test driving them through a
real disconnect. A future refactor that inverts the order of
clearIdleTimer + streams.delete (or that misses one of the aux maps)
would leak per-tunnel memory in a way unit tests cannot catch.

Spin up a real http.Server with attachUpgrade and a real ws.WebSocket
client (same self-contained pattern as
pilot-tunnel-integration.test.ts). Four cases:

  - HTTP request mid-flight: open a real loopback HTTP request, wait
    for the bridge to forward http_req to the agent, terminate the
    agent WS, assert the loopback request resolves with 502 (the
    teardownStream path) and the manager marks the node Offline.
  - TCP stream with bytes outstanding: openTcpStream from the bridge,
    ack open from the test agent, write some bytes, terminate the
    tunnel, assert the TcpStream emits 'close' and the bridge is
    gone from the manager.
  - Reconnect with the long-lived token after a clean close does NOT
    bump tunnels_replaced (no live tunnel to replace).
  - Reconnect WHILE the prior tunnel is still live DOES bump
    tunnels_replaced. Inverse case proves the counter wiring is
    correct in both directions.

Self-contained: no shared helper modules, no dependencies on other
in-flight pilot test files. Can land independently of PRs #982,
#983, or #985.

* test(pilot): address PR E code-review on disconnect tests

Two small findings:

  - Defensive: attach a no-op 'error' listener on the TcpStream in
    test #2 after the 'open' event has fired. teardownStream only
    emits 'error' for unaccepted streams today, so the listener is
    not exercised; the listener exists so a future refactor that
    delays accepted=true past 'open' cannot crash the worker on an
    unhandled 'error' event.
  - Removed a stale cross-file reference in the header comment that
    pointed at pilot-tunnel-integration.test.ts; that file lives in
    a separate in-flight branch and does not exist on main.

No behavior change. All 4 disconnect tests pass.

* chore(test): drop unused PROTOCOL_VERSION import

The import was leftover from an earlier draft and ESLint flagged it
as no-unused-vars (error level for symbols not prefixed with _),
failing the lint job in CI.

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

Operations


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.
