Kubernetes explained.

Aug 12, 2020 · A Kubernetes deployment makes this process automated and repeatable. Deployments are entirely managed by the Kubernetes backend, and the whole update process is performed on the server side without client interaction. The Kubernetes deployment object lets you: Deploy a replica set or pod. Update pods and replica sets. For example, where we previously created a single instance of the Pod, we might create a Kubernetes Deployment YAML example to tell Kubernetes to manage a set of replicas of that Pod — literally, a ReplicaSet — to make sure that a certain number of them are always available. Kubernetes Deployment Use CasesEgress is a very loosely defined term in the Kubernetes ecosystem. Unlike its counterpart, egress traffic is not controlled by any standard Kubernetes API or a proxy. This is because most of the egress traffic is not revenue-generating and, in fact, can be completely optional. For situations when a Pod needs to communicate with an external ...Kubernetes cluster networking can be more than a bit confusing, even for engineers with hands-on experience working with virtual networks and request routing.
