How it works
immortal
immortalctl
immortaldir
⭕ immortal
runs a command or script detached from the controlling terminal
as a Unix daemon, it will supervise and restart the service if it has
been terminated. The service can be controlled by querying a Unix socket
“immortal.sock” (immortalctl
), this allows to remotely have full control over
the service if required by exposing the socket using a web server like Nginx.
immortal - Starts and monitor a service
immortaldir - Directory to scan for services *.yml
immortalctl - Control existing services
In a nutshell, immortal
is a command that runs forever an application or
service. In most common cases immortal
is called by imortaldir
which
searches for immortal configuration files run.yml and ideally
starts at boot time in order to persist across reboots.
In some cases there is a need to “daemonize” a command but not to keep it persistent across reboots, for this cases immortal can be used directly with out the need of a configuration file or either no need to use immortaldir.
immortalctl still will show the status of existing processes besides been available to control them.
