Pods in K8s
Pods are the smallest deployable units of computing that you can create and manage in Kubernetes.
Deployments in K8s
A Deployment provides declarative updates for Pods and ReplicaSets.
You describe a desired state in a Deployment, and the Deployment Controller changes the actual state to the desired state at a controlled rate. You can define Deployments to create new ReplicaSets, or to remove existing Deployments and adopt all their resources with new Deployments.
Services in K8s
An abstract way to expose an application running on a set of Pods as a network service.
ReplicaSets in K8s
A ReplicaSet's purpose is to maintain a stable set of replica Pods running at any given time. As such, it is often used to guarantee the availability of a specified number of identical Pods.
