# Retrieve Node Configuration for Clusters Created Using Hostname

## Problem

Retrieve Node Configuration for Clusters Created Hostname.

## Environment

* Platform9 Managed Kubernetes - v5.2 & K8s v1.20 and Higher

## Answer

Single Node Cluster created with *hostname:true.*

{% tabs %}
{% tab title="None" %}

```none
$ kubectl get nodes
NAME                    STATUS   ROLES    AGE     VERSION
sanchit-mav.novalocal   Ready    master   5m37s   v1.20.5
```

{% endtab %}
{% endtabs %}

Starting Kubectl Proxy on the node.

{% tabs %}
{% tab title="None" %}

```none
$ kubectl proxy --port=8001 &
[1] 12428

$ Starting to serve on 127.0.0.1:8001
```

{% endtab %}
{% endtabs %}

With hostname of the node in curl call.

{% tabs %}
{% tab title="None" %}

```none
$ curl -sSL http://localhost:8001/api/v1/nodes/sanchit-mav.novalocal/proxy/configz -vvv
* About to connect() to localhost port 8001 (#0)
*   Trying ::1...
