// prints info. on the kubernetes cluster deployed on Azure Batch.
// 1. Register workflow type(s) with the workflow factory

// Sample workflow types can be found in './core/Flows' directory
engine.AddWorkflow(WorkflowTypes.K8S_DETAILS);
engine.AddWorkflow(WorkflowTypes.TESK_DEPLOY);
// engine.AddWorkflow("test-tesk-deployment"); // verify Tesk deployment
// 4. Execute workflows in the context of a batch job on the engine
engine.ExecuteWorkflow(
"k8s-job1", // name of Azure Batch job
poolMetaData, // metadata to be assigned to the batch pool
jobMetaData); // metadata to be assigned to the job
