description	Deploy a PowerSentry worker agent daemon on the jump/bastion host itself (e.g., rb-master). Use when asked to monitor the jump host or deploy a worker agent on a directly-accessible server without a bastion.

PowerSentry Deploy — Jump Host Worker Daemon

Overview

Deploys the PowerSentry worker agent directly on the jump/bastion host (e.g., rb-master). Unlike deploying to a Proxmox host behind a bastion, the jump host itself is accessed directly (no intermediate hop).

Prerequisites

• Direct SSH access to the jump host (via Tailscale or public IP)
• SSH key ~/.ssh/id_ed25519
• Python 3 on the jump host
• .env configured with JUMP_HOST empty (direct connection)

.env Configuration

# proxmox-power-monitor/.env
PROXMOX_HOST=<jump-host-ip>     # The jump host's own IP
JUMP_HOST=                       # Leave empty for direct connection
REMOTE_USER=ubuntu               # Jump host username

Or pass directly via CLI (no .env needed):

cd proxmox-power-monitor
./deploy.sh <jump-host-ip>
# Example: ./deploy.sh 100.86.93.41

Deployment Steps

1. Run deploy script (direct mode)

cd proxmox-power-monitor
./deploy.sh <jump-host-ip>

Since no JUMP_HOST is provided, the script will:

• Connect directly (no proxy jump)
• Check Python 3 availability
• Install websockets dependency
• Copy all Python files to /opt/proxmox-power-monitor
• Set permissions

2. SSH into the jump host

ssh ubuntu@<jump-host-ip>

3. Install and start the worker

cd /opt/proxmox-power-monitor

# Install with control panel connection
python3 cli.py install --control-panel=ws://<control-panel-host>:8765/worker

# Start the daemon
python3 cli.py start

# Verify
python3 cli.py status
python3 cli.py stats --recent=5

Network Considerations

• The jump host needs outbound connectivity to the control panel WebSocket port (:8765)
• If the control panel is on a public server (e.g., dk1), this should work by default
• If the control panel is on the same LAN, ensure routing is correct

Service Management

Same as any worker agent:

systemctl status powersentry-worker
journalctl -u powersentry-worker -f
cd /opt/proxmox-power-monitor && python3 cli.py uninstall
