Question

do rolling updates declared with a deployment take effect if i manually delete pods of the replica set with kubectl delete pods or with the dashboard? Will the minimum required no of pods be maintained?

Answer 1

• 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)
