我正在尝试获取当前正在运行的服务容器，以便像在 Portainer.io 中一样将它们可视化。

Portainer 显示当前运行的机器和副本，如5/8。

/services我可以使用带有端点的引擎 api 获得所需的副本号。我找不到的是当前正在运行的服务容器。

服务端点返回类似的结果；

我已经意识到在引擎 API 容器中可以使用两个端点来检索；第一个是/containers，第二个是/tasks。例如，为了让服务/任务端点的运行容器具有两个过滤器，可以使用；http://192.168.4.142:1777/v1.40/tasks?filters={"service":{"my-service":true},"desired-state":{"running":true}}

此端点返回服务的运行容器总数，/services端点返回所需的数量，因此可以找到正在运行的所需容器的数量。
