如何在滚动更新后删除关闭的Docker服务任务？
如何在滚动更新后删除关闭的Docker服务任务？
提问于 2017-01-18 03:12:23
我正在使用Docker Swarm在AWS上测试服务。我最近对服务进行了更新，如下所示：
docker service update --image TestImage:v2 --update-parallelism 2 \
--update-delay 10s TestService2更新按预期工作，并且服务将任务容器更新为v2。然而，快速的docker service ps TestService2 | grep "v1"显示了一堆关闭的TestImage:v1任务。

谢谢!

这些服务的容器在滚动更新后被删除；您只剩下关闭的容器的日志。
您可以使用以下命令限制您看到的数量
docker swarm update --task-history-limit 5 Stack Overflow用户
