NOMAD Client Service

nomad-client service

We run the nomad client as a Linux service so it starts automatically at startup.

In /etc/systemd/system/nomad-client.service:

[Unit]
Description=Nomad Spect Client task
After=network.target

[Service]
Type=simple
User=nmrsu
WorkingDirectory=/opt/nomad-spect-client

# Set PATH to the exact nvm version's bin:
Environment=PATH=/home/nmrsu/.nvm/versions/node/v20.12.2/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin

# Run bash file (see below) directly:
ExecStart=/home/nmrsu/bin/nomad-client

# Get the service to attempt a restart on failure
Restart=on-failure
RestartSec=2s

[Install]
WantedBy=multi-user.target

Then in ~/bin/nomad-client:

#!/usr/bin/env bash

/home/nmrsu/.nvm/versions/node/v20.12.2/bin/npm run verbose --prefix /opt/nomad-spect-client

Ensure the above file is executable e.g. chmod +x ~/bin/nomad-client.

To start, stop, view status:

sudo systemctl start nomad-client
sudo systemctl stop nomad-client
sudo systemctl status nomad-client

To make sure it runs when the system reboots:

sudo systemctl enable nomad-client

To view the logs, run:

sudo journalctl -u nomad-client
