备选方案

名称，简写默认描述
--format, -f​使用给定的Go模板格式化输出
--prettyfalse以人性化的格式打印信息

父命令

命令描述
docker节点管理Swarm节点

相关命令

命令描述
docker node demote从群中的经理中降级一个或多个节点
docker node inspect 在一个或多个节点上显示详细信息
docker node ls列出群中的节点
docker node promote将一个或多个节点提升为群中的经理
docker node ps列出在一个或多个节点上运行的任务，默认为当前节点
docker node rm从群中删除一个或多个节点
docker node update更新节点

扩展描述

返回有关节点的信息。默认情况下，该命令将所有结果呈现在JSON数组中。您可以指定一个替代格式来为每个结果执行给定的模板。Go的文本/模板包描述了格式的所有细节。

实例

检查节点
