Replicaset

What Happens When You Deploy a Pod That Has a Same Label as Replicaset Pod


In Kubernetes, replica sets use labels to effectively manage pod replicas, ensuring the desired number of identical pods are running according to the deployment configuration.

Here's how it works:

Selector Matching:

  • The replica set defines a selector field in its specification. This selector uses label pairs like app: webserver and version: v1.0.
  • When the replica set starts, it scans through all existing pods in the cluster.
  • Any pod with labels matching the replica set's selector is considered part of the set and managed by it.
