Service dependencies

Pebble can take service dependencies into account when managing services: this is done with the requires list in the service definition.

Simply put, you can configure a list of other services in the requires section to indicate this service requires those other services to start correctly.

When Pebble starts a service, it also starts the services which that service depends on (configured with requires). Conversely, when stopping a service, Pebble also stops services which depend on that service.

For the start order of the services, see Service start order.

For example, if service nginx requires logger, pebble start nginx will start both nginx and logger (in an undefined order). Running pebble stop logger will stop both nginx and logger; however, running pebble stop nginx will only stop nginx (nginx depends on logger, not the other way around).
