Spring Cloud Task App Starters

Elston

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 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

  • Download as starters from this version of Spring Initializr

Available Applications

  • composed-task-runner
