class MultipleEksClusterStack extends Stack {
constructor(scope: App, id: string) {
super(scope, id);
const vpc = new ec2.Vpc(this, 'Vpc', { natGateways: 1 });
new eks.Cluster(this, 'EnabledCluster', {
vpc,
...getClusterVersionConfig(this, eks.KubernetesVersion.V1_30),
bootstrapSelfManagedAddons: true,
});
new eks.Cluster(this, 'DisabledCluster', {
vpc,
...getClusterVersionConfig(this, eks.KubernetesVersion.V1_30),
bootstrapSelfManagedAddons: false,
});
}
