docker service ps打印出来的错误信息被截断了怎么办？

 

【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。
