Systemd

Run with systemd

Once you've verified that you can run Fleet in your shell, you'll likely want to keep Fleet running in the background and after the server reboots. To do that we recommend using systemd.

Below is a sample unit file, assuming a fleet user exists on the system. Any user with sufficient permissions to execute the binary, open the configuration files, and write the log files can be used. It is also possible to run as root, though as with any other web server it is discouraged to run Fleet as root.

[Unit]
Description=Fleet
After=network.target

[Service]
User=fleet
Group=fleet
LimitNOFILE=8192
ExecStart=/usr/local/bin/fleet serve \
  --mysql_address=127.0.0.1:3306 \
  --mysql_database=fleet \
  --mysql_username=root \
  --mysql_password=toor \
  --redis_address=127.0.0.1:6379 \
  --server_cert=/tmp/server.cert \
  --server_key=/tmp/server.key \
  --logging_json

[Install]
WantedBy=multi-user.target

Once you created the file, you need to move it to /etc/systemd/system/fleet.service and start the service.

sudo mv fleet.service /etc/systemd/system/fleet.service
sudo systemctl start fleet.service
sudo systemctl status fleet.service

sudo journalctl -u fleet.service -f

Making changes

Sometimes you'll need to update the systemd unit file defining the service. To do that, first open /etc/systemd/system/fleet.service in a text editor, and make your modifications.

Then, run

sudo systemctl daemon-reload
sudo systemctl restart fleet.service
