Just re-create the namespace:

kubectl delete ns squad-mb
kubectl create ns squad-mb

This will recursively delete everything inside.

To delete all resources of a given namespaces use:

kubectl delete all --all -n {my-namespace}

Explanation:

  • Usage: kubectl delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)]) [options]
  • all: all resources types. If you want to delete only some resources you can do kubectl delete deployments,pods,replicasets,services --all
  • --all: delete all resources of a type (or all types if using all). Example: kubectl delete pods --all
  • -n: selects the desired namespace. If empty the command is valid for the default namespace of your context. You can select all namespaces with --all-namespaces
