v3.0验证安装结果出错

采用本地部署方案（8个主机模式），安装过程无错误，非常顺利。但按照手册中最后一步验证安装结果时没有出现“Welcome to KubeSphere”字样。具体日志如下：
error: error executing jsonpath “{.items[0].metadata.name}”: Error executing template: array index out of bounds: index 0, length 0. Printing more information for debugging the template:
template was:
{.items[0].metadata.name}
object given to jsonpath engine was:
map[string]interface {}{“apiVersion”:“v1”, “items”:[]interface {}{}, “kind”:“List”, “metadata”:map[string]interface {}{“resourceVersion”:"", “selfLink”:""}}

error: expected ‘logs [-f] [-p] (POD | TYPE/NAME) [-c CONTAINER]’.
POD or TYPE/NAME is a required argument for the logs command
See ‘kubectl logs -h’ for help and examples
不是特别明白以上错误的指向，还请专家解答。
