Once you have a secret in Kubernetes, if you know it’s name, you can delete it.
How to find the secret name
You can get the secret name as follows:
kubectl get secrets
This will produce an output similar to:
NAME TYPE DATA AGE
admin-user-pass Opaque 2 11s
Now that we have the secret name, we can delete the secret
Deleting a Secret in Kubernetes
kubectl delete secret admin-user-pass
