-d | --dns <dns or ip address>
Specifies the external DNS/ IP address of the Kubernetes cluster.
-d | --dns <dns or ip address> | --dns aks
Specifies the external DNS/ IP address of the Kubernetes cluster.
If 'aks' is set as value, the DNS value is retrieved from the AKS. --aks-name and --aks-rg are needed.
When --use-local-k8s is specified the external DNS is automatically set to localhost.
-h | --help
Displays this help text and exits the script.
--image-build
Build images ( default is to not build all images) .
--image-push
Upload images to the container registry ( default is not pushing to the custom registry)
-n | --app-name <the name of the app>
Specifies the name of the application ( default: eshop) .
--namespace <namespace name>
Specifies the namespace name to deploy the app. If it doesn' t exists it will be created ( default: eshop) .
-p | --docker-password <docker password>

-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: new ly cre ated, date-based time stamp, with 1-minute resolution .
-u | --docker-user <docker username>
The tag used for the newly created docker images. Default: latest.
-u | --docker-username <docker username>
The Docker username used to logon to the custom registry, supplied using the -r parameter.
--use-local-k8s

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
FROM THE CURRENT CONFIGURATION CONTEXT AND NAMESPACE .
It is recommended that you check your selected namespace, 'eshop' by default, is already in use.
Every deployment and service done in the namespace will be deleted .
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.
