Certstream as systemd service

Since Certstream comes as a single executable, you might want to run it via systemd. To do that, just create this systemd service at /etc/systemd/system/certstream.service:

[Unit]
Description=Certstream Server
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=on-failure
RestartSec=5
ExecStart=/opt/certstream-server-go/certstream-server-go
WorkingDirectory=/opt/certstream-server-go/
User=certstream

[Install]
WantedBy=multi-user.target

Note the User=certstream - this will make the application run as the user "certstream". Make sure to create a user account for the application. Don't run apps as root! Now you can do all the cool systemd stuff. Run systemctl start certstream to start certstream.

Use systemctl status certstream to get information about the currently running process.

With systemctl enable certstream you can configure certstream to run at boot.
