如何在滚动更新后删除 shutdown Docker 服务任务？

Question

我正在使用 Docker Swarm 来测试 AWS 上的服务。我最近应用了这样的服务更新：

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

更新按预期进行，服务将任务容器更新为 v2。然而，快速 docker service ps TestService2 | grep "v1" 显示了一堆关闭 TestImage:v1 任务。

如何在不转到每个单独的集群节点和运行ning docker rm 退出容器的情况下删除这些？我认为没有 docker service 命令可以执行此操作，我已经查看了文档，但是有没有人知道我可以运行在 Swarm Manager 上清理节点？

谢谢！

Answer 1

滚动更新后删除了这些服务的容器；你只是留下了那些被关闭的日志。

您可以使用

限制您看到的数量

docker swarm update --task-history-limit 5

我做到了

docker swarm update --task-history-limit 2

docker-machine stop manager1

docker-machine start manager1

和

PS C:\> docker service ps web | Select-String "manager1"
