Spring Cloud Task Application Starters are Spring Boot applications that may be any process includinghttps://projects.spring.io/spring-batch[Spring Batch] jobs that do not run forever, and they end/stop at some point. Spring Cloud Task Applications can be used with Spring Cloud Data Flow to create, deploy, and orchestrate short-lived data microservices.

Spring Cloud Task Application Starters are standalone executable applications that can be used for on-demand use-cases such as database migration, machine learning, and scheduled operations. These applications can run independently on a variety of runtime platforms including Cloud Foundry, Kubernetes, Docker, or even on your laptop. If you are new to task app starters

Features

• Run standalone as Spring Boot applications

• Orchestrate as ephemeral data microservices

• Consume data microservice applications as maven or docker artifacts

• Override configuration parameters via command-line, environment variables, or YAML file

• Provide infrastructure to test the applications in isolation

Available Applications

• timestamp

• timestamp-batch

Running a sample Task Launcher

Step 1 - Download the latest timestamp application from here [eg: /2.1.1.RELEASE/timestamp-task-2.1.1.RELEASE.jar]

Step 2 - Run timestamp application
