为什么Docker会显示每项服务的上一个任务？我想只看到当前任务处于所需状态＆＃34; Running＆＃34;。我希望清理已经移动到除＃34; Running＆＃34;之外的所需状态的旧任务。如何实现这一目标？
rus@coder:~/Docker$ docker stack ps getstartedlab

我知道，我使用grep命令，但它不是最佳解决方案
rus@coder:~/Docker$ docker stack ps getstartedlab | grep "Running"

Docker列出与堆栈关联的每个容器/任务。您可以使用过滤器来仅获取应该运行的过滤器。如果您想要保留更多或更少的容器，可以选择调整每个服务的任务历史记录。这可以在安装期间设置或使用以下命令更新：
docker swarm update --task-history-limit 3

要查看仅根据官方documentation运行的任务，需要使用过滤器标记-f。
在您的情况下，它将是docker stack ps -f "desired-state=running" getstartedlab
