Steps:

1. Delete any previous cluster if any

kind delete cluster

2. Create the configuration file for kind:

• File name: kind-config-node-port.yaml

• Content:

# I got this config from:
# https://github.com/kubernetes-sigs/kind/issues/1875
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
  apiServerAddress: "127.0.0.1"
  apiServerPort: 6443
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 30080
    hostPort: 30080
    listenAddress: "127.0.0.1"
    protocol: TCP
  - containerPort: 30081
    hostPort: 30081
    listenAddress: "127.0.0.1"
    protocol: TCP    

$ kind create cluster --config=kind-config-node-port.yaml 
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.24.0) 🖼 
 ✓ Preparing nodes 📦  
 ✓ Writing configuration 📜 
 ✓ Starting control-plane 🕹️ 
 ✓ Installing CNI 🔌 
 ✓ Installing StorageClass 💾 
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Thanks for using kind! 😊

3. Install the operator:

kubectl apply -k github.com/minio/operator/

4. Install the tenant:

kubectl apply -k ~/operator/examples/kustomization/tenant-lite

5. Since we have one node only, remove one replica from operator so we have only one:

6. Wait for Tenant to be ready:

7. Then, change the service to become NodePort:

8. Match the port of the service with the port available in your host:

9. Then you can access the UI via https://localhost:30080/login:
