☑️ Prevent use of deprecated APIs in Kubernetes v1.24
Kubernetes version 1.24 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 1.24:
| API version | Resource kind |
|---|---|
storage.k8s.io/v1beta1 | CSIStorageCapacity |
flowcontrol.apiserver.k8s.io/v1beta2 | FlowSchema, PriorityLevelConfiguration |
flowcontrol.apiserver.k8s.io/v1beta1 | FlowSchema, PriorityLevelConfiguration |
Targeted objects by this rule (types of kind): (See table above)
Complexity: easy (What does this mean?)
Policy as code identifier: K8S_DEPRECATED_APIVERSION_1.24
This rule will fail
If one of the deprecated API versions is used for a resource:
apiVersion: storage.k8s.io/v1beta1
kind: CSIStorageCapacity
Rule output in the CLI
$ datree test *.yaml
>> File: failExample.yaml
❌ Prevent use of deprecated APIs in Kubernetes v1.24 [1 occurrence]
💡 Incorrect value for key `apiVersion` - the version of the resource you are trying to use is deprecated in k8s v1.24
How to fix this failure
Use a supported API version instead of the deprecated one:
| Deprecated API version | Supported API version |
|---|---|
storage.k8s.io/v1beta1 | storage.k8s.io/v1 |
flowcontrol.apiserver.k8s.io/v1beta2 | flowcontrol.apiserver.k8s.io/v1beta3 |
flowcontrol.apiserver.k8s.io/v1beta1 | flowcontrol.apiserver.k8s.io/v1beta3 |
Example:
apiVersion: storage.k8s.io/v1
kind: CSIStorageCapacity
