Deploying Go Programs as Daemons in Ubuntu

Initiating a Go program as a daemon in Ubuntu necessitates meticulous planning and execution. Evidently, you intend to oversee the process using Monit. However, it's essential to delve into the intricacies specific to Go development for effective implementation.

Fundamental Considerations

To commence, compile your program into an executable (go build). Subsequently, you have the option of employing an upstart script to designate the program as a daemon or leveraging a third-party tool such as daemonize.

daemonize: An External Solution

I recommend adopting the daemonize approach due to its independence from upstart, which varies across systems. With daemonize, you can effortlessly launch your application as:

daemonize -p /var/run/myapp.pid -l /var/lock/subsys/myapp -u nobody /path/to/myapp.exe

This command comprehensively prepares your application for operation as a Unix daemon, including pid file creation, locking, and user specification. By adhering to these guidelines, you ensure seamless deployment and efficient monitoring of your Go program.
