### Testing networking
To verify that the new cluster is working properly, we can deploy a
tiny test deployment and see if it is globally reachable:
```
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 2
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.20.0-alpine
ports:
- containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
name: nginx-service
spec:
selector:
app: nginx
ports:
- protocol: TCP
port: 80
```
Using curl to access a sample service from the outside shows that
networking is working:
```
% curl -v http://[2a0a:e5c0:0:aaaa::e3c9]
