I am new to Azure Kubernetes Service. I have created an Azure Kubernetes cluster and tried to deploy some workload in it. The .yaml file as follows

- apiVersion: v1
  kind: Namespace
  metadata:
    name: azure-vote
  spec:
    finalizers:
      - kubernetes

            env:
              - name: ALLOW_EMPTY_PASSWORD
                value: 'yes'
            resources:

When I deploy this .yaml via Azure CLI it gives me a validation error but doesn't indicate where is it? When I run the kubectl apply -f ./filename.yaml --validate=false it gives "cannot unmarshal array into Go value of type unstructured.detector" error. However, when I run the same yaml in Azure portal UI it runs without any error. Appreciate if someone can mention the reason for this and how to fix this.

CodePudding user response：

I tried to run the code you have provided in the Portal as well as Azure CLI. It successfully got created in Portal UI by adding the YAML code but using Azure CLI I received the same error as you :

After doing some modifications in your YAML file and validating it , I ran the same command again and it successfully got deployed in Azure CLI:
