Node Infra

Infrastructure scripts for Retina Node fleet management.

Mender Auto-Accept

Automatically accepts pending Mender devices. Runs on your central server (not on devices).

Install

# 1. Clone to server
git clone https://github.com/offworldlabs/node-infra.git ~/retina/node-infra
cd ~/retina/node-infra/mender-auto-accept

# 2. Install Python dependencies
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

# 3. Configure
cp .env.example .env
nano .env  # Add your MENDER_PAT

# 4. Install systemd timer (runs every 30s)
sudo cp systemd/*.service systemd/*.timer /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now mender-auto-accept.timer

# 5. Verify
systemctl status mender-auto-accept.timer
journalctl -u mender-auto-accept -f

Test locally

cd ~/retina/node-infra/mender-auto-accept
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
export MENDER_PAT=your-token
export NODE_ID_PREFIX=ret
python auto_accept.py

Configuration

Edit .env:

Variable	Required	Description
MENDER_PAT	Yes	Personal Access Token from Mender UI
MENDER_SERVER	No	Default: https://hosted.mender.io
NODE_ID_PREFIX	No	Only accept nodes with this prefix (e.g., ret)

How it works

1. Timer triggers every 30 seconds
2. Script fetches pending devices from Mender API
3. Filters by node_id prefix (if configured)
4. Accepts matching devices
