Kubernetes ConfigMap 创建失败 cannot unmarshal number into Go struct field ConfigMap.data of type string

错误信息

ConfigMap in version "v1" cannot be handled as a ConfigMap: json: cannot unmarshal number into Go struct field ConfigMap.data of type string

ConfigMap yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: myconfigmap
data:
  username: zhangsan
  password: 123

原因

上述案例中的password填写的是123，Go语言在转换时认为了是一个number类型的变量，所以转换失败。

解决方法

对于纯数字类型的变量，可以添加双引号，即password: "123"。
