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
