Ensure ingress rule creation - kubernetes

Question

My problem: i create ingress rule via kubernetes-client:
try (InputStream is = IOUtils.toInputStream(crd, StandardCharsets.UTF_8)) {
client.load(is).inNamespace(namespaceName).createOrReplace();
}
Where is - yaml file with ingress rule like:
spec:
ingressClassName: nginx
rules:
- host: {{host}}
http:
paths:
- backend:
service:
name: {{service_name}}
port:
number: 80
path: /
pathType: ImplementationSpecific
But in my task i need ensure that the rule is created, i need wait or check status in loop.
What is the best way to do it?
Thanx!

I think you might be able to do it with waitUntilCondition:
try (KubernetesClient client = new KubernetesClientBuilder().build()) {
Ingress ingress = client.network().v1().ingresses()
.load(IngressRuleWaitUntilCondition.class.getResourceAsStream("/ingress-rule.yml"))
.get();
client.resource(ingress)
.inNamespace("default")
.createOrReplace();
client.network().v1()
.ingresses()
.inNamespace("default")
.resource(ingress)
.waitUntilCondition(i -> !i.getSpec().getRules().isEmpty(), 2, TimeUnit.MINUTES);
}
