To delete a namespace in Kubernetes, you can use the kubectl command-line tool. Deleting a namespace will remove all resources (pods, services, deployments, etc.) within that namespace, so it's essential to ensure that you won't lose any important data before proceeding. Here's how you can delete a namespace:

kubectl delete namespace <namespace_name>

Replace <namespace_name> with the name of the namespace you want to delete. Here's an example:

kubectl delete namespace s7royce

This command will delete the namespace named mynamespace, along with all the resources within it.

Before deleting a namespace, it's a good idea to verify which resources are present in that namespace to avoid accidentally deleting important data. You can list all resources within a namespace using the following command:

kubectl get all -n <namespace_name>

Replace <namespace_name> with the name of the namespace you want to check. For example:

kubectl get all -n s7royce

This command will list all resources (pods, services, deployments, etc.) within the mynamespace namespace.

After confirming that it's safe to delete the namespace, you can proceed with the kubectl delete namespace command as shown earlier.

Deleting a namespace is a destructive operation, so exercise caution and ensure that you won't lose any important data before proceeding. Once a namespace is deleted, it cannot be recovered, and all its resources will be permanently removed from the cluster.
