我在本地环境中的SCDF平台（kubernetes）上创建了一个组合任务。但是我想知道为什么在所有单个任务停止后组合任务不会停止。
spring-cloud-dataflow-server-kubernetes：1.7.2。发布
组合任务运行程序版本：docker：springcloudtask / compositetaskrunner-task：2.1.0.M1
组成的任务定义：
task create --name dbsales-pipeline-st --definition "ftp-source-task-st: ftp-source-task --host=ftp-host --username=ftp-user --port=21 --remote-directory='/trial/' --delete-remote-file=true --password=password --source-exchange-name=xml-transform-exchange-source --source-exchange-routing-key=st --name=ftp-source-task-st && xml-transform-source-st: xml-transform-task --sink-exchange-name=xml-transform-exchange-sink --source-queue-name=xml-transform-source-st --sink-exchange-routing-key=st --name=xml-transform-source-st && <ftp-sink-task-aaa: ftp-sink-task --host=ftp-host --username=ftp-user --port=21 --remote-directory='/trial-output/aaa/' --password=password --source-queue-name=xml-transform-sink-st-aaa --name=ftp-sink-task-aaa || ftp-sink-task-bbb: ftp-sink-task --host=ftp-host --username=ftp-user --port=21 --remote-directory='/trial-output/bbb/' --password=password --source-queue-name=xml-transform-sink-st-bbb --name=ftp-sink-task-bbb >"

我确实尝试了一个简单的组合任务，但它确实停止了。
task create foo --definition "t1: timestamp && t2: timestamp"
是否有任何参数可以迫使合成任务在完成后停止？
答案 0 :(得分：0)
通常发生的迹象是组合任务运行程序的spring.cloud.task.closecontextEnabled未设置为“ true”时。
您可以在Spring Cloud Task docs中了解有关该属性的更多信息。
最近，在spring-cloud-task-app-starters/composed-task-runner#60和spring-cloud/spring-cloud-dataflow#2667上对此进行了讨论。
