Create first chart named nginxfirst like following:

# mkdir nginxfirst
# cd nginxfirst/
# ls
# helm create nginxfirst
Creating nginxfirst

└── nginxfirst
    ├── charts
    ├── Chart.yaml

    │   ├── _helpers.tpl
    │   ├── ingress.yaml
    │   ├── NOTES.txt
    │   └── service.yaml
    └── values.yaml

3 directories, 7 files

Edit the values.yaml file:

replicaCount: 1
  tag: 1.7.9
  pullPolicy: IfNotPresent
  name: nginx
  type: ClusterIP
  externalPort: 80
  internalPort: 80

Keep others the same.

--dry-run means you want to verificate the configuration.

Install this chart book via:

# helm install --name firstnginx . --set service.type=NodePort

Get the URL via following command:

1. Get the application URL by running these commands:
  export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services firstnginx-nginxfirst)
  export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT

Finally you will see a running nginx instance.
