【解决方法】

1. 用Format属性：

   这个其实解决不了截断的问题，不过可以显示更少的列，看起来更清楚。

Formatting The formatting options (--format) pretty-prints tasks output using a Go template. Valid placeholders for the Go template are listed below: Placeholder Description .ID Task ID .Name Task name .Image Task image .Node Node ID .DesiredState Desired state of the task (running,?shutdown, or?accepted) .CurrentState Current state of the task .Error Error .Ports Task published ports When using the?--format?option, the?service ps?command will either output the data exactly as the template declares or, when using thetable?directive, includes column headers as well. The following example uses a template without headers and outputs the?Name?and?Image?entries separated by a colon for all tasks: $ docker service ps --format "{{.Name}}: {{.Image}}" top top.1: busybox top.2: busybox top.3: busybox

1. 用—no-trunc属性

   docker service ps --no-trunc <service name>

当然，解决方法1和2可以联合起来用。
