What happened?

My K3S test container is up and I am able to create namespace, services etc. in it.

            V1Service service = new V1Service()
            .metadata(new V1ObjectMeta().name(serviceName).annotations(annotations))
            .spec(new V1ServiceSpec()
                    .addPortsItem(new V1ServicePort()
                            .port(80)
                            .targetPort(new IntOrString(8080)))
                    .selector(Collections.singletonMap("app", "my-app"))
                    .type("ClusterIP"));

    api.createNamespacedService(LHTestConstants.NAMESPACE, service).execute();

But when I try to run a PATCH command using the below code it gives a SSLHandshake error:

           V1Patch patch = new V1Patch(patchJson);
           V1Service patchedService = PatchUtils.patch(
                    V1Service.class,
                    () ->
                            coreV1Api.patchNamespacedService(
                                            serviceName,
                                            namespace,
                                            patch)
                                    .buildCall(null),
                    V1Patch.PATCH_FORMAT_JSON_PATCH);

Error: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Relevant log output

javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Additional Information

No response

Start by reproducing the PATCH request in the K3S test setup and compare it with the successful namespace and service calls shown in the issue. Trace the SSL and certificate handling used by coreV1Api.patchNamespacedService and PatchUtils.patch; done means the PATCH command succeeds without the PKIX SSLHandshakeException.
