☑️ Prevent use of removed APIs in Kubernetes v1.25
Kubernetes version 1.25 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 1.25:
| API version | Resource kind |
|---|---|
batch/v1beta1 | CronJob |
discovery.k8s.io/v1beta1 | EndpointSlice |
events.k8s.io/v1beta1 | Event |
autoscaling/v2beta1 | HorizontalPodAutoscaler |
policy/v1beta1 | PodDisruptionBudget, PodSecurityPolicy |
node.k8s.io/v1beta1 | RuntimeClass |
Targeted objects by this rule (types of kind): (See table above)
Complexity: easy (What does this mean?)
Policy as code identifier: K8S_REMOVED_APIVERSION_1.25
This rule will fail
If one of the removed API versions is used:
apiVersion: events.k8s.io/v1beta1
kind: Event
Rule output in the CLI
$ datree test *.yaml
>> File: failExample.yaml
❌ Prevent use of removed APIs in Kubernetes v1.25 [1 occurrence]
💡 Incorrect value for key `apiVersion` - the version of the resource you are trying to use is removed in k8s v1.25
How to fix this failure
Use a supported API version instead of the removed one:
| Removed API version | Supported API version |
|---|---|
batch/v1beta1 | batch/v1 |
discovery.k8s.io/v1beta1 | discovery.k8s.io/v1 |
events.k8s.io/v1beta1 | events.k8s.io/v1 |
autoscaling/v2beta1 | autoscaling/v2 |
policy/v1beta1 | policy/v1 |
node.k8s.io/v1beta1 | node.k8s.io/v1 |
Example:
apiVersion: events.k8s.io/v1
kind: Event
