Support for Traefik CRDs IngressRoute, Middleware, etc

[ghost]

Is there support for Traefik CRDs available already, or how would I go about creating that with the least amount of effort, so I can create Traefik ingresses including rewriting etc.?

I've started trying to add the beans myself, but I'm running into an issue:

ReconciliationDispatcher - Kubernetes exception 0 Cannot edit com.tsystemsmms.cmcc.cmccoperator.ingress.traefik.IngressRoute with visitors, no builder was found during event processing

I've manually created the beans (using Lombok) for IngressResource from the Traefik CRD, and I'm creating a resource like this:

    HasMetadata resource = new IngressRoute(targetState.getResourceMetadataFor(name), IngressRouteSpec.builder()
                    .routes(List.of(
                            IngressRouteItem.builder()
                                    .kind("Service")
...
            .build()));
    kubernetesClient.resource(resource).inNamespace(namespace).createOrReplace()

My bean looks like this:

@Version("v1alpha1")
@Group("traefik.containo.us")
public class IngressRoute extends CustomResource<IngressRouteSpec, IngressRouteStatus> implements Namespaced {
    public IngressRoute(ObjectMeta metadata, IngressRouteSpec spec) {
        super();
        this.setMetadata(metadata);
        this.setSpec(spec);
        this.setStatus(new IngressRouteStatus());
    }
}

Any ideas?

If I follow the example in the cheatsheet verbatim:

            IngressRoute resource = new IngressRoute(targetState.getResourceMetadataFor(name), IngressRouteSpec.builder()
                    .routes(List.of(
                            IngressRouteItem.builder()
                                    .kind("Service")
                                    .match(match)
                                    // .middlewares() // depending on rewrites etc
                                    .services(List.of(TraefikServiceRef.builder()
                                            .kind("Service")
                                            .name(path.getService())
                                            .port(new IntOrString("http"))
                                            .build())
                                    ).build()
                    ))
                    .tls(IngressRouteTls.builder()
                            .secretName(tls.getSecretName())
                            .domains(List.of(IngressRouteTlsDomain.builder()
                                    .main(hostname)
                                    .build()))
                            .build())
                    .build());
            MixedOperation<IngressRoute, KubernetesResourceList<IngressRoute>, Resource<IngressRoute>> ingressResourceClient = targetState.getKubernetesClient().resources(IngressRoute.class);
            try {
                ingressResourceClient.inNamespace(resource.getMetadata().getNamespace()).createOrReplace();
            } catch (RuntimeException e) {
                log.debug("That didn't work", e);
            }

I'm getting:

java.lang.IllegalArgumentException: Nothing to create.
	at io.fabric8.kubernetes.client.dsl.base.BaseOperation.createOrReplace(BaseOperation.java:303)

You're not providing any object to DSL for creating. Perhaps you meant:

           try {
                ingressResourceClient.inNamespace(resource.getMetadata().getNamespace()).createOrReplace(resource);
            } catch (RuntimeException e) {
                log.debug("That didn't work", e);
            }

You can create these objects as custom resources using typed (which you're currently using)[0] or dynamic api[1]
