Service

A service is a process that typically runs in the background as part of the ACE ecosystem. Special command line tooling exists to manage the starting, stopping and getting the status of services.

Execution Modes

A service can be ran in one of three execution modes.

• debug mode
• foreground mode
• background (daemon) mode

debug mode

A service that runs in debug mode typically runs as a single thread on a single process. This makes it easier for the developer to drop into debugging shells.

To start a service in debug mode execute ace service start --debug

Use Control-C to stop a service running in debug mode.

foregorund mode

A service that runs in foreground mode runs normally but waits for the service to exit before returning control to the shell.

To start a service in foreground mode execute ace service start --foreground.

Use Control-C to stop a service running in the foreground.

background (daemon) mode

A service that runs in background (daemon) mode detaches itself from the foreground and executes as a forked process in the background.

This is the default mode if no other mode is specified.

Management and Configuration

Service management and configuration is covered in the administration guide.
