+deploy.sh: deploys the $app_name application to a Kubernetes cluster using Helm.
+Parameters:
+  --aks-name <AKS cluster name>
+    The name of the AKS cluster. Required when the registry (using the -r parameter) is set to "aks".
+  --aks-rg <AKS resource group>
+    The resource group for the AKS cluster. Required when the registry (using the -r parameter) is set to "aks".
+  -b | --build-solution
+    Force a solution build before deployment (default: false).
+  -d | --dns <dns or ip address>
+    Specifies the external DNS/ IP address of the Kubernetes cluster. 
+    When --use-local-k8s is specified the external DNS is automatically set to localhost.
+  -h | --help
+    Displays this help text and exits the script.
+  -n | --app-name <the name of the app>
+    Specifies the name of the application (default: eshop).
+  -p | --docker-password <docker password>
+    The Docker password used to logon to the custom registry, supplied using the -r parameter.
+  -r | --registry <container registry>
+    Specifies the container registry to use (required), e.g. myregistry.azurecr.io.
+  --skip-clean
+    Do not clean the Kubernetes cluster (default is to clean the cluster).
+  --skip-image-build
+    Do not build images (default is to build all images).
+  --skip-image-push
+    Do not upload images to the container registry (just run the Kubernetes deployment portion).
+    Default is to push the images to the container registry.
+  --skip-infrastructure
+    Do not deploy infrastructure resources (like sql-data, no-sql or redis).
+    This is useful for production environments where infrastructure is hosted outside the Kubernetes cluster.
+  -t | --tag <docker image tag>
+    The tag used for the newly created docker images. Default: newly created, date-based timestamp, with 1-minute resolution.
+  -u | --docker-user <docker username>
+    The Docker username used to logon to the custom registry, supplied using the -r parameter.
+  --use-local-k8s
+    Deploy to a locally installed Kubernetes (default: false).
+
+It is assumed that the Kubernetes cluster has been granted access to the container registry.
+If using AKS and ACR see link for more info: 
+https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auth-aks
+
+WARNING! THE SCRIPT WILL COMPLETELY DESTROY ALL DEPLOYMENTS AND SERVICES VISIBLE
+FROM THE CURRENT CONFIGURATION CONTEXT.
+It is recommended that you create a separate namespace and confguration context
+for the $app_name application, to isolate it from other applications on the cluster.
+For more information see https://kubernetes.io/docs/tasks/administer-cluster/namespaces/
+You can use namespace.yaml file (in the same directory) to create the namespace.
