Namespaces
Most resources in the Kubernetes configuration are namespaced, or owned by a parent namespace, allowing resources with the same name to safely coexist and providing a dividing line between applications. This isn't true for all resources, particularly those intended for configuration by the cluster administrator. This can be checked with the kubectl api-resources
command described in Administration.
Default namespaces
By default, the following namespaces exist:
default
is usually the default context.kube-public
is created for use by shared resources, e.g. ConfigMaps.kube-system
contains the system Pods, used to administer the cluster.
Children
