Basic Kubernetes concepts

There are several Kubernetes concepts that are relevant when using the Astra REST API.

Objects

The objects maintained within a Kubernetes environment are persistent entities representing the configuration of the cluster. These objects collectively describe the state of the system including the cluster workload.

Namespaces

Namespaces provide a technique for isolating resources within a single cluster. This organizational structure is useful when dividing the types of work, users, and resources. Objects with a namespace scope need to be unique within the namespace, while those with a cluster scope must be unique across the entire cluster.

Labels

Labels can be associated with the Kubernetes objects. They describe attributes using key-value pairs and can enforce an arbitrary organization on the cluster which can be useful to an organization but are outside the core Kubernetes operation.
