Start process right after deply

How to start a process at deploy time ?

I used to place a Start Time Event with PT0S as Duration. But this has some disadvantages (async restart etc.).

Are you deploying the process as part of a process application?

Yes, and I’m using a shared process engine.

You can annotate a method with @PostDeploy to be called after process application deployment and then start a process instance. Here’s how it is done in the invoice demo application:

github.com

camunda/camunda-bpm-platform/blob/master/examples/invoice/src/main/java/org/camunda/bpm/example/invoice/InvoiceProcessApplication.java#L51-L65


@PostDeploy
public void startFirstProcess(ProcessEngine processEngine) {
  createUsers(processEngine);


  //enable metric reporting
  ProcessEngineConfigurationImpl processEngineConfiguration = (ProcessEngineConfigurationImpl) processEngine.getProcessEngineConfiguration();
  processEngineConfiguration.setDbMetricsReporterActivate(true);
  processEngineConfiguration.getDbMetricsReporter().setReporterId("REPORTER");


  startProcessInstances(processEngine, "invoice", 1);
  startProcessInstances(processEngine, "invoice", null);


  //disable reporting
  processEngineConfiguration.setDbMetricsReporterActivate(false);
}

Cheers,
Thorben

Thanks Thorben.

I’m using this solution with a lot of cron processes.

I’m asking myself if that is the best way to delete old job/running process versions and start the new.
