kubectl add-ons

Question

We are trying to install kubecost Add-ons in the EKS cluster while installing we are getting this issue

{An error occurred (InvalidParameterException) when calling the CreateAddon operation: ConfigurationValue provided in request is not supported: Yaml schema validation failed with error: [$.kubecostAggregator: is not defined in the schema and the schema does not allow additional properties]

admission webhook "opa-validating.kube-yahoo.hookfg" denied the request with the message: 
"DENY: missing spec.containers[].resources.limits.cpu kubecost/cost-analyzer container; aggregator: 
DENY: missing spec.containers[].resources.limits.cpu kubecost/cost-analyzer container; cloud-cost" }

We tried with the yaml configuration policy but it shows the access policy issue

Yaml #

apiVersion: v1
kind: ConfigMap
metadata:
  name: kubecost-configmap
data:
  example-json-file: |
    {
      "containers": [
	    {
		  "name":"aggregated"
          "resources": {
            "limits": {
              "cpu": "2000m",
              "memory": "2Gi"
            },
            "requests": {
              "cpu": "1000m",
              "memory": "1Gi"
            }
          }
        },
	{
	  "name": "cloud-cost"
	  "resources": {
		"limits": {
		  "cpu": "2000m",
		  "memory": "2Gi"
		},
		"requests": {
		  "cpu": "1000m",
		  "memory": "1Gi"
		}
      }
	]
   }
  }

In your YAML configuration, there are syntax errors such as missing commas between elements in the JSON array and incorrect indentation. Additionally, the JSON format should be properly formatted within the YAML file

Could you please correct your Yaml config and try again

```
apiVersion: v1
kind: ConfigMap
metadata:
  name: kubecost-configmap
data:
  example-json-file: |
    {
      "containers": [
        {
          "name": "aggregated",
          "resources": {
            "limits": {
              "cpu": "2000m",
              "memory": "2Gi"
            },
            "requests": {
              "cpu": "1000m",
              "memory": "1Gi"
            }
          }
        },
        {
          "name": "cloud-cost",
          "resources": {
            "limits": {
              "cpu": "2000m",
              "memory": "2Gi"
            },
            "requests": {
              "cpu": "1000m",
              "memory": "1Gi"
            }
          }
        }
      ]
    }

```
Make sure to adjust the configuration according to the requirements and schema expected by the Kubecost addon. Additionally, ensure that you have proper permissions and access policies to create the addon in your EKS cluster.

We have removed the indentations and formatted the JSON but still getting the same error.
An error occurred (InvalidParameterException) when calling the CreateAddon operation: ConfigurationValue provided in request is not supported: Json schema validation failed with error:

"DENY: missing spec.containers[].resources.limits.cpu kubecost/cost-analyzer container; aggregator: DENY: missing spec.containers[].resources.limits.cpu kubecost/cost-analyzer container; cloud-cost" }

Can you help us how can we configure the values for above missing CPU limits for containers that could help in creating add-on. We tried multiple ways but getting the same schema validation failed.
