Scaling Applications With Kubernetes ReplicaSets
What Is The Difference Between ReplicaSet And Deployment?
ReplicaSet provides low level of abstraction with basic scaling features but kubernetes deployment provides higher level of abstraction having features like versioning, rollingupdate and many more .
What Action Taken By ReplicaSet If You Delete A Pod Running In The Cluster ?
If you delete a pod running in the cluster then the ReplicaSet will automatically schedule another pod to run, so that it can maintain the desired state.
What Is The Purpose Of Using ReplicaSet?
ReplicaSet is used to maintain a desired number of pods running on the Kubernetes cluster. Using ReplicaSet ensures high availability as it automatically replaces any failed pods .
What Will Happen If I Delete The ReplicaSet?
If you delete the ReplicaSet then all the running pods managed by ReplicaSet will also deleted.
What Is The Command Used To Scale Up Or Down In A ReplicaSet ?
You can use the following command to scale up or down:
kubectl scale replicaset <replicaset_name> --replicas=<desired_number_of_replicas>
Scaling Applications With Kubernetes ReplicaSets
Kubernetes is an orchestration tool used to scale , deploy and manage the containerized application. It provides ReplicaSet which is used to run a desired number of pods on any given time . In this guide, I will first discuss what Kubernetes is. Then I will discuss about ReplicaSets. After this I will walk you through the different steps to scale applications using Kubernetes ReplicaSet.
