ReplicaSet — Kubernetes

A Kubernetes Deployment is used to tell Kubernetes how to create or modify instances of the pods that hold a containerized application.

Deployments can scale the number of replica pods, enable the rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary.

A ReplicaSet is a process that runs multiple instances of a Pod and keeps the specified number of Pods constant.

ReplicaSet ← Theory Part

Its purpose is to maintain the specified number of Pod instances running in a cluster at any given time to prevent users from losing access to their application when a Pod fails or is inaccessible.

A Replication Controller is a structure that enables you to easily create multiple pods, and then make sure that that number of pods always exists. If a pod does crash, the Replication Controller replaces it.

First, check any pods running on minikube

kubectl get pods

Kubernetes architecture only run

kubectl get all -A

Deploy → ReplicaSet → Pod
