【解决方法】
- 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:
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 |
- 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。
