1-) Structure components
2-) Avoid conflicts between teams
3-) Share services between different environments
4-) Access and Resource Limits on namespace level
5-) each ns must define own configmap and secrets
6-) accessing service in another namespace: mysql-service.namespace 

by default components are created in a default ns

kubectx -> set default name space and avoid adding -n on every command.

minikube addons enable ingress
(k8s ngnix ingress controller)

kubectl get pod -n kube-system --> nginx ingresses
