Yaml.dump and Yaml.loadAs log warnings related to V1JSONSchemaProps #2741
Description
Describe the bug
When using the Yaml.dump method to serialize a K8S object (eg - V1Pod) several warnings related to CRD schema attributes are output from snakeyaml.
The same issue occurs when using the Yaml.loadAs method (which is actually the method I am using in production).
See example code and output below.
Client Version
18.0.1
Kubernetes Version
N/A
Java Version
Java 17
To Reproduce
Run the YAML code example
Expected behavior
The output should not contain warnings related to missing schema attributes for CRDs.
KubeConfig

Operating System
Linux
Additional context
The (example) code I am running is below:
public class YamlExample {
public static void main(String[] args) throws IOException, ApiException, ClassNotFoundException {
V1Pod pod =
new V1PodBuilder()
.withNewMetadata()
.withName("apod")
.endMetadata()
.withNewSpec()
.addNewContainer()
.withName("www")
.withImage("nginx")
.withNewResources()
.withLimits(new HashMap<>())
.endResources()
.endContainer()
.endSpec()
.build();
System.out.println(Yaml.dump(pod));
}
}
The output from the example code is below:
