☑️ Prevent use of removed APIs in Kubernetes v1.26
Kubernetes version 1.26 stopped serving several APIs for different resource types.
When deploying a resource with a removed API version, the Kubernetes engine will reject it.
The following resources are removed in version 1.26:
| API version | Resource kind |
|---|---|
flowcontrol.apiserver.k8s.io/v1beta1 | FlowSchema, PriorityLevelConfiguration |
autoscaling/v2beta2 | HorizontalPodAutoscaler |
Targeted objects by this rule (types of kind): (See table above)
Complexity: easy (What does this mean?)
Policy as code identifier: K8S_REMOVED_APIVERSION_1.26
This rule will fail
If one of the removed API versions is used:
apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
Rule output in the CLI
$ datree test *.yaml
>> File: failExample.yaml
❌ Prevent use of removed APIs in Kubernetes v1.26 [1 occurrence]
💡 Incorrect value for key `apiVersion` - the version of the resource you are trying to use is removed in k8s v1.26
How to fix this failure
Use a supported API version instead of the removed one:
| Removed API version | Supported API version |
|---|---|
flowcontrol.apiserver.k8s.io/v1beta1 | flowcontrol.apiserver.k8s.io/v1beta3 |
autoscaling/v2beta2 | autoscaling/v2 |
Example:
apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
