### Connect Infra App

Infra App will automatically work with Docker Desktop. Simply open it by clicking on the **Cluster Switcher** and then choosing **docker-desktop:**

Voila! Infra App is now connected to Docker Desktop's Kubernetes cluster:

### Installing Metrics Server

Metrics server isn't included with Docker Desktop's installation of Kubernetes, and the default metrics-server setup guide won't work out of the box. Follow the steps below to install metrics server:

Download the latest `components.yaml` file from <https://github.com/kubernetes-sigs/metrics-server/releases> and open it in your text editor.

Then, add the line `--kubelet-insecure-tls` under the `args:` section:

```
apiVersion: apps/v1
kind: Deployment
metadata:
  name: metrics-server
  namespace: kube-system
  labels:
    k8s-app: metrics-server
spec:
  selector:
    matchLabels:
      k8s-app: metrics-server
  template:
    metadata:
      name: metrics-server
      labels:
        k8s-app: metrics-server
    spec:
      serviceAccountName: metrics-server
      volumes:
      # mount in tmp so we can safely use from-scratch images and/or read-only containers
      - name: tmp-dir
        emptyDir: {}
      containers:
      - name: metrics-server
        image: k8s.gcr.io/metrics-server-amd64:v0.3.6
        imagePullPolicy: IfNotPresent
        args:
          - --cert-dir=/tmp
          - --secure-port=4443
          - --kubelet-insecure-tls # Add this line
        ports:
        - name: main-port
          containerPort: 4443
          protocol: TCP
        securityContext:
          readOnlyRootFilesystem: true
          runAsNonRoot: true
          runAsUser: 1000
        volumeMounts:
        - name: tmp-dir
          mountPath: /tmp
      nodeSelector:
        kubernetes.io/os: linux
        kubernetes.io/arch: "amd64"
```

{% hint style="warning" %}
**Warning**: This setting should only be used for the local Docker Desktop Kubernetes cluster, and not recommended for any hosted or production clusters.
{% endhint %}

Last, apply the modified `components.yaml` config file to your cluster.

```
kubectl apply -f components.yaml
```
