3. Kubernetes Using (Minikube) -

brew install minikube minikube start — vm-driver=virtualbox

4. Network gateways (Istio-ingress) - To expose our service Install & Setup -> https://istio.io/latest/docs/setup/getting-started/ Execute istio.yml Location -> ( kysokApp -> istio.yml)

kubectl apply -f istio.yml

5. Create namespace for kyosk app

kubectl create namespace kyoskapp

6. Create & injectistio gateway Excute kyoskapp-gateway.yml

kubectl apply -f myapp-gateway.yml kubectl label namespace kyoskapp istio-injection=enabled

7. Create docker image

docker build -t kysokapp .

8. Deploy Location -> (kyoskApp -> kyoskapp.yml)

kubectl apply -f kyoskapp.yml

9. Forward port
