☑️ Prevent use of deprecated APIs in Kubernetes v1.22

Kubernetes version 1.22 stopped serving several APIs for different resource types. When deploying a resource with a deprecated API version, the Kubernetes engine will reject it.

The following resources are deprecated in version 1.22:

API versionResource kind
autoscaling/v2beta1HorizontalPodAutoscaler
HorizontalPodAutoscalerList

Targeted objects by this rule (types of kind): (See table above)

Complexity: easy (What does this mean?)

Policy as code identifier: K8S_DEPRECATED_APIVERSION_1.22


This rule will fail​

If one of the deprecated API versions is used for a resource:

apiVersion: autoscaling/v2beta1
kind: HorizontalPodAutoscaler

Rule output in the CLI​

$ datree test *.yaml

>> File: failExample.yaml
❌ Prevent use of deprecated APIs in Kubernetes v1.22 [1 occurrence]
💡 Incorrect value for key `apiVersion` - the version of the resource you are trying to use is deprecated in k8s v1.22

How to fix this failure​

Use a supported API version instead of the deprecated one:

Deprecated API versionSupported API version
autoscaling/v2beta1autoscaling/v2

Example:

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
