# Access

In this part, you will

- Create a K8s YAML workload that will deploy sample application and a service of Type LoadBalancer
- Verify we can access the application via the LoadBalancer

* * *

## Create Workload YAML

We are using a nginx deployment in this example to create a service of type LoadBalancer.

- Copy the K8s YAML manifest below to a file called "nginx-lb.yaml"
- Edit lines 30 to match the name of the IPAddressPool we configured earlier

```
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nginx
  name: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx
        imagePullPolicy: Always
        name: nginx
      restartPolicy: Always
---
apiVersion: v1
kind: Service
metadata:
  labels:
    app: nginx
  name: nginx
  annotations:
    metallb.universe.tf/address-pool: first-pool
spec:
  ports:
  - port: 80
    protocol: TCP
    targetPort: 80
  selector:
    app: nginx
  type: LoadBalancer
```

* * *

## Create Workload

In this step, we will create a workload based on the YAML from the previous step and publish it to our cluster.

- Click on Application -> Workloads
- Click on "Create New Workload" with the name "nginx-lb"
- Select "K8s YAML" for the Package Type
- Select "Upload files manually" for Artifact Sync
- Select the "metallb-system" namespace from the dropdown
- Click on "CONTINUE"

- Select the file created in the previous step

- Set the Drift Action to "NotSet"
- Select a cluster for the placement policy
- Click on "SAVE AND GO TO PUBLISH"

- Publish the workload

* * *

## Verify Workload

- Click on the Kubectl button on the cluster to open a virtual terminal and run the following kubectl command

```
kubectl get services -n metallb-system

NAME                      TYPE           CLUSTER-IP     EXTERNAL-IP      PORT(S)        AGE
metallb-webhook-service   ClusterIP      10.99.114.3    <none>           443/TCP        22m
nginx                     LoadBalancer   10.104.43.59   192.168.15.200   80:30245/TCP   83s
```

- Verify you can securely access the nginx app using your web browser

## Recap

Congratulations!

You have successfully created a custom cluster blueprint with the "metallb" addon and applied it to a cluster. You can now use this blueprint on as many clusters as you require.
