A replicaSet is a kubernetes object that spawns pods
Once we delete the replicaSet the pods attached to it get automatically deleted.


Deleting the replicaSet without deleting the pods:

Below is a Yaml file of a replicaSet called "replica_1":


We can create the replicaSet using the below command:


We check the details of our replicaSet using the below command:


The replicaSet "has" three pods replicas of a "debian" image.

Displaying the pods:

We use the below command to display our pods:


Deleting our replicaSet:

To delete our replicaSet "replica_1" without deleting the pods attached to it, we use the below command:


Remark:

The --cascade option set to "orphan" tells the command to only delete the replicaSet without deleting the pods

Cheking the pods:

After deleting the replicaSet, we check our pods:


We see that our pods are still running.

Remark:

If we re-create our replicaSet using the "kubectl create" command, the replicaSet "replica_1" will get re-attached to the pods above.
That is the role of labels and selectors.
