Kubectl Namespaces and Context

Namespaces limit scope, aka 'virtual clusters'
Not related to Docker / Linux namespaces
Won't need them in small clusters
There are some built-in, to hide system stuff from kubectl users
kubectl get namespaces
kubectl get all --all-namespaces
Context changes kubectl cluster and namespace, see ~/.kube/config file
kubectl config get-contexts
kubectl config set* <-- see help for this
