K8 Initial Namespaces

 Initial namespaces

Kubernetes starts with four initial namespaces:

default

Kubernetes includes this namespace so that you can start using your new cluster without first creating a namespace.

kube-node-lease

This namespace holds Lease objects associated with each node. Node leases allow the kubelet to send heartbeats so that the control plane can detect node failure.

kube-public

This namespace is readable by all clients (including those not authenticated). This namespace is mostly reserved for cluster usage, in case that some resources should be visible and readable publicly throughout the whole cluster. The public aspect of this namespace is only a convention, not a requirement.

kube-system

The namespace for objects created by the Kubernetes system.
