3. Creating and Launching Tasks on Kubernetes

  1. Create a task and launch it

    Let’s register the timestamp task app and create a simple task definition and launch it.

    dataflow:>app register --type task --name timestamp --uri docker:springcloudtask/timestamp-task:1.2.0.RELEASE --metadata-uri maven://org.springframework.cloud.task.app:timestamp-task:jar:metadata:1.2.0.RELEASE
dataflow:>task create task1 --definition "timestamp"
dataflow:>task launch task1

    We can now list the tasks and executions using these commands:

    dataflow:>task list
╔═════════╤═══════════════╤═══════════╗
║Task Name│Task Definition│Task Status║
╠═════════╪═══════════════╪═══════════╣
║task1    │timestamp      │running    ║
╚═════════╧═══════════════╧═══════════╝

dataflow:>task execution list
╔═════════╤══╤════════════════════════════╤════════════════════════════╤═════════╗
║Task Name│ID│         Start Time         │          End Time          │Exit Code║
╠═════════╪══╪════════════════════════════╪════════════════════════════╪═════════╣
║task1    │1 │Fri May 05 18:12:05 EDT 2017│Fri May 05 18:12:05 EDT 2017│0        ║
╚═════════╧══╧════════════════════════════╧════════════════════════════╧═════════╝

  2. Destroy the task

    dataflow:>task destroy --name task1
