  • Yes, the scheduler will make sure (as long as you have the correct resources) that the number of desired pods are met. 

  • If you delete a pod, it will recreate it. 

  • Also deleting a service won't delete the Replica set. if you remove Service or deployment you want to remove all resources which Service created.

  •  Also having a single replica for a deployment is usually not recommended because you cannot scale out and are treating in a specific way

  • Any app should be `Ingress` -> `Service` -> `Deployment` -> (volume mount or 3rd-party cloud storage)

  • You can skip ingress and just have `LoadBalancer (service)` -> `Deployment` (or Pod but they don't auto restart, deployments do)
