Error: unable to recognize "mongo-configmap.yaml": no matches for kind "ConfigMap" in version "V1"

I am following a MongoDB tutorial on Kubernetes, but when I create the configuration map, it gives me this error:

error: unable to recognize "mongo-configmap.yaml": no matches for kind "ConfigMap" in version "V1"

This is the mongo-configmap.yaml file:

apiVersion: V1
kind: ConfigMap
metadata:
  name: mongodb-configmap
data:
  database_url: mongodb-service
Solution

  • The version should be lower case.

    apiVersion: v1
lang-none

    You can run the below command to refer to the attributes.

    kubectl explain cm | head

    Or

    kubectl explain cm --recursive | grep -i <attribute> or head

    KIND:     ConfigMap
VERSION:  v1

DESCRIPTION:
     ConfigMap holds configuration data for pods to consume.

FIELDS:
   apiVersion    <string>
   binaryData    <map[string]string>
   data    <map[string]string>
