如何在滚动更新后删除关闭Docker服务任务？

Question

我正在使用Docker Swarm来测试AWS上的服务.我最近对此服务应用了这样的更新:

 docker service update --image TestImage:v2 --update-parallelism 2 \
--update-delay 10s TestService2

更新按预期工作,服务将任务容器更新为v2.然而,快速docker service ps TestService2 | grep "v1"揭示了一堆关机TestImage:v1任务.

如何在不去往每个单独的swarm节点并docker rm在已退出的容器上运行的情况下删除它们？我不认为这是一个docker service命令,我已经浏览了文档,但是有没有人知道我可以在Swarm Manager上运行的hack或脚本来清理节点？

谢谢!

滚动更新后,将删除这些服务的容器; 你只需要留下那些被关闭的日志.

您可以限制使用的数字

docker swarm update --task-history-limit 5
