Sorry guys for bothering you, but I'm going crazy on that... I'm trying to create an EKS cluster, create the Rancher Cluster representation and then, import that cluster.

const cluster = new eks.Cluster(name, {
    vpcId: vpc.id,
    subnetIds: vpc.publicSubnetIds,
    storageClasses: "gp2",
    deployDashboard: false,
    nodeGroupOptions: {
        spotPrice: "0.038",
        instanceType: "m5.large",
        desiredCapacity: 6,
        minSize: 6,
        maxSize: 24,
    }
});
