llmport-agent 0.1.6

Node execution agent for llm-port cluster-managed runtimes.

llm_port_node_agent

llm_port_node_agent is the host-side execution bridge for llm-port node clusters.

It does not perform cluster scheduling. The backend remains authoritative for:

• desired state
• placement and routing policy
• GPU-aware filtering and load-balancing

The agent responsibilities are:

• enroll with one-time token
• maintain authenticated outbound stream
• execute node commands (Docker runtime lifecycle)
• report heartbeat, inventory, command timeline, and events

Quick Start

1. Create token in backend admin:
   • POST /api/admin/system/nodes/enrollment-tokens
2. Set environment variables on node host:
   • LLM_PORT_NODE_AGENT_BACKEND_URL
   • LLM_PORT_NODE_AGENT_ENROLLMENT_TOKEN
   • LLM_PORT_NODE_AGENT_AGENT_ID
   • LLM_PORT_NODE_AGENT_HOST
3. Start service:
   • llmport-agent (foreground, for testing)
   • llmport-agent start (install as systemd service)

Commands

Command	Description
llmport-agent	Run in foreground (test connectivity, Ctrl+C to stop)
llmport-agent start	Install and start as a systemd service (picks up LLM_PORT_NODE_AGENT_* env vars)
llmport-agent stop	Stop and disable the systemd service
llmport-agent status	Show systemd service status

Environment Variables

• LLM_PORT_NODE_AGENT_BACKEND_URL default http://127.0.0.1:8000
• LLM_PORT_NODE_AGENT_AGENT_ID default hostname
• LLM_PORT_NODE_AGENT_HOST default hostname
• LLM_PORT_NODE_AGENT_ADVERTISE_HOST default LLM_PORT_NODE_AGENT_HOST
• LLM_PORT_NODE_AGENT_ADVERTISE_SCHEME default http (allowed: http, https)
• LLM_PORT_NODE_AGENT_ENROLLMENT_TOKEN one-time token for initial enrollment
• LLM_PORT_NODE_AGENT_STATE_PATH default /var/lib/llmport-agent/state.json
• LLM_PORT_NODE_AGENT_HEARTBEAT_INTERVAL_SEC default 15
• LLM_PORT_NODE_AGENT_INVENTORY_INTERVAL_SEC default 60
• LLM_PORT_NODE_AGENT_RECONNECT_MIN_SEC default 2
• LLM_PORT_NODE_AGENT_RECONNECT_MAX_SEC default 30
• LLM_PORT_NODE_AGENT_REQUEST_TIMEOUT_SEC default 20
• LLM_PORT_NODE_AGENT_VERIFY_TLS default true
• LLM_PORT_NODE_AGENT_LOKI_URL Loki push endpoint (e.g. http://10.0.0.1:3100). When set, the agent collects system logs (journald on Linux, Event Log on Windows) and pushes them to Loki with labels {job="node-agent", host="<hostname>", level="..."}.
• LLM_PORT_NODE_AGENT_LOG_BATCH_SIZE default 100 — max log lines per collection cycle
• LLM_PORT_NODE_AGENT_LOG_FLUSH_INTERVAL_SEC default 5 — seconds between log collection cycles

Binary Installation (no Python required)

Pre-built standalone binaries are available on the GitHub Releases page for Linux (x86_64), Windows (x86_64), and macOS (universal).

Linux

curl -fLO https://github.com/llm-port/llm-port-node-agent/releases/latest/download/llmport-agent-linux-x86_64
sudo install -m 0755 llmport-agent-linux-x86_64 /usr/local/bin/llmport-agent

Then install the systemd service (see below) or run directly:

export LLM_PORT_NODE_AGENT_BACKEND_URL=http://your-backend:8000
export LLM_PORT_NODE_AGENT_ENROLLMENT_TOKEN=tok_xxx

# Test connectivity first (foreground, Ctrl+C to stop)
llmport-agent

# Once working, install as a service
llmport-agent start

Windows

Download llmport-agent-windows-x86_64.exe from the releases page and run:

$env:LLM_PORT_NODE_AGENT_BACKEND_URL = "http://your-backend:8000"
$env:LLM_PORT_NODE_AGENT_ENROLLMENT_TOKEN = "tok_xxx"
.\llmport-agent-windows-x86_64.exe

macOS

curl -fLO https://github.com/llm-port/llm-port-node-agent/releases/latest/download/llmport-agent-macos-universal
chmod +x llmport-agent-macos-universal
export LLM_PORT_NODE_AGENT_BACKEND_URL=http://your-backend:8000
export LLM_PORT_NODE_AGENT_ENROLLMENT_TOKEN=tok_xxx
./llmport-agent-macos-universal

Via CLI

llmport node agent deploy --backend-url http://your-backend:8000

The CLI auto-detects pre-built binaries in the workspace dist/ directories and uses them instead of cloning + setting up a Python venv.

Systemd

A unit file template is available at:

• deploy/systemd/llmport-agent.service
