+## Configure ingress nginx with Milvus
+This topic introduces how to configure ingress nginx with Milvus. 
+For more details, refer to [ingress-nginx](https://learn.microsoft.com/en-us/azure/aks/ingress-tls?tabs=azure-cli).
+
+
+### Configure ingress nginx
+
+- Set env.
+```bash
+export DNS_LABEL="milvustest" # Your DNS label must be unique within its Azure location.
+export NAMESPACE="ingress-basic"
+```
+
+- Install ingress nginx
+```bash
+helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
+helm repo update
+helm install ingress-nginx ingress-nginx/ingress-nginx \
+    --create-namespace \
+    --namespace $NAMESPACE \
+    --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-dns-label-name"=$DNS_LABEL \  
+    --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"=/healthz
+```
+
+- Get External IP address.
+```bash
+kubectl --namespace $NAMESPACE get services -o wide -w ingress-nginx-controller
+```
+
+- Configure an FQDN for your ingress controller.
+```bash
+# Public IP address of your ingress controller
+IP="MY_EXTERNAL_IP"
+
+# Get the resource-id of the public IP
+PUBLICIPID=$(az network public-ip list --query "[?ipAddress!=null]|[?contains(ipAddress, '$IP')].[id]" --output tsv)
+
+# Update public IP address with DNS name
+az network public-ip update --ids $PUBLICIPID --dns-name $DNS_LABEL
+
+# Display the FQDN
+az network public-ip show --ids $PUBLICIPID --query "[dnsSettings.fqdn]" --output tsv
+# sample output: milvustest.eastus2.cloudapp.azure.com
+```
+
+
+### Install cert-manager
+
+```bash
+helm repo add jetstack https://charts.jetstack.io
+helm repo update
+helm install cert-manager jetstack/cert-manager \
+    --namespace $NAMESPACE \
+    --set installCRDs=true
+```
+
+### Create a CA cluster issuer
+
+- Create a cluster issuer, such as cluster-issuer.yaml, using the following example manifest. Replace MY_EMAIL_ADDRESS with a valid address from your organization.
+```yaml
+apiVersion: cert-manager.io/v1
+kind: ClusterIssuer
+metadata:
+  name: letsencrypt
+spec:
+  acme:
+    server: https://acme-v02.api.letsencrypt.org/directory
+    email: MY_EMAIL_ADDRESS
+    privateKeySecretRef:
+      name: letsencrypt
+    solvers:
+    - http01:
+        ingress:
+          class: nginx
+```
+
+- Apply the issuer using the kubectl apply command.
+```bash
+kubectl apply -f cluster-issuer.yaml
+```
+
+
+### Deploy Milvus
+refer to [Azure](https://milvus.io/docs/azure.md), notice the config `service.type` value, you need change to `ClusterIP`. 
+
+
+### Create Milvus ingress route
+```bash
+kubectl apply -f ingress.yaml
+``` 
+
+the ingress.yaml contents:
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: my-release-milvus
+  annotations:
+    cert-manager.io/cluster-issuer: letsencrypt
+    nginx.ingress.kubernetes.io/backend-protocol: GRPC
+    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
+    nginx.ingress.kubernetes.io/proxy-body-size: 2048m
+spec:
+  ingressClassName: nginx
+  tls:
+  - hosts:
+    - milvustest.eastus2.cloudapp.azure.com # the FQDN
+    secretName: tls-secret
+  rules:
+    - host: milvustest.eastus2.cloudapp.azure.com
+      http:
+        paths:
+          - path: /
+            pathType: Prefix
+            backend:
+              service:
+                name: my-release-milvus
+                port:
+                  number: 19530
+```
+
+### Verify
+```bash
+kubectl get certificate 
+NAME         READY   SECRET       AGE
+tls-secret   True    tls-secret   8m7s
+kubectl get ingress
+NAME                CLASS   HOSTS                                   ADDRESS        PORTS     AGE
+my-release-milvus   nginx   milvustest.eastus2.cloudapp.azure.com   EXTERNAL-IP   80, 443   8m15s
