 Make sure that the Attu pod can access the Milvus service. In the example provided this connects directly to `my-release-milvus:19530`. Change this based on the Milvus service name. A more flexible way to achieve this would be to introduce a `ConfigMap`. See this [example]("https://raw.githubusercontent.com/zilliztech/attu/main/examples/attu-k8s-deploy-ConfigMap.yaml") for details.

+  server_name localhost;
+
+  location /attu/ {
+    proxy_pass http://localhost:3000/;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    rewrite ^/attu/(.*)$ /$1 break;
+  }
+}
