 Note that this is overwritting the kubectl that comes with k3s. That is a special version that reads its config from /etc/rancher/k3s/k3s.yaml and must therefore be run with sudo. The version we are installing here is the standard version that reads its config from $HOME/.kube/config.

 ### Configure kubectl
 
- kubectl uses a default configuration file  **$HOME/.kube/config** to connect to the cluster. Here we will copy the configuration file from the server to the workstation.

-### Create a service account to run the IOCs
-
-Inside of our new namespace we will create a service account that will be used to run the IOCs. Kubernetes uses a declarative model where you define the desired state of the system and Kubernetes will make it so. Here we will create a service account and a secret that will be used to authenticate the service account. In both cases these are defined directly using command line YAML which kubectl passes to the Kubernetes API.
-
-Create the account:
-
-```bash
-kubectl apply -f - <<EOF
-apiVersion: v1
-kind: ServiceAccount
-metadata:
-    name: bl03t-priv
-EOF
-```
-
-Generate a login token for the account:
-
-```bash
-kubectl apply -f - <<EOF
-apiVersion: v1
-kind: Secret
-metadata:
-    name: bl03t-priv-secret
-    annotations:
-        kubernetes.io/service-account.name: bl03t-priv
-type: kubernetes.io/service-account-token
-EOF
-```

 ### Completed
 
 That's it. You now have installed the necessary software to start experimenting with IOCs on Kubernetes.
