17. Kubernetes

18. Kubernetes
• Pods : Its a collection of containers and the basic unit of deployment
• Replication controller: Deploys the specified number of pods and make sure
the system is in the desired state
• Deployments: It contains the details of the pods and the replication controller
It will deploy the replica sets which will deploy pods and in turn deploy
container
• Services: Its a group of pods that can be accessed as a single unit. If one of
the pod goes down. a new a pod is created and user has to contact only the
service and not to the pods directly

19. Demo
• Deploy ASP.NET Application
• Deploy ASP.NET Core Application
