方法一(查询单个)

k describe node 节点名称

显示如下

方法二(查询所有节点)

使用如下模板

{{printf "%-50s %-12s\n" "Node" "Taint"}}
{{- range .items}}
    {{- if $taint := (index .spec "taints") }}
        {{- .metadata.name }}{{ "\t" }}
        {{- range $taint }}
            {{- .key }}={{ .value }}:{{ .effect }}{{ "\t" }}
        {{- end }}
        {{- "\n" }}
    {{- end}}
{{- end}}

将其保存到文件中,然后像这样引用它：

kubectl get nodes -o go-template-file="./nodes-taints.tmpl"

会得到类似如下的输出：

Node                                            Taint
