This is the library for writing drivers for clustd. Drivers are intended to run on the same machine as a clustd instance and connect to that local daemon. Drivers are simple to implement and designed to be a plug & play system to control the system when a master machine goes down.
The clustd project is what actually provides the cluster implementation. The daemon runs in the background and will execute driver triggers when a machine becomes a master.

class MyDriver extends DriverMachine {
constructor() {
super({
id: 'driver-mydriver',
secret: Config.secret
}, Config.host);
}
async trigger(isMaster: boolean): Promise<void> {
if (isMaster) {
this.logger.info('Starting service...');
// Do things...
} else {
this.logger.info('Stopping service...');
// Do things...
}
}
}
const d = new MyDriver();
d.connect();That's all there is to it! trigger is automatically invoked when the clustd instance becomes a master or is no longer master. That simple action can then invoke actions on the system.
