A pseudo-ID for the cluster, set to the UID of the kube-system namespace.

Note

K8s doesn't have support for obtaining a cluster ID. If this is ever added, we will recommend collecting the k8s.cluster.uid through the official APIs. In the meantime, we are able to use the uid of the kube-system namespace as a proxy for cluster ID. Read on for the rationale.
Every object created in a K8s cluster is assigned a distinct UID. The kube-system namespace is used by Kubernetes itself and will exist for the lifetime of the cluster. Using the uid of the kube-system namespace is a reasonable proxy for the K8s ClusterID as it will only change if the cluster is rebuilt. Furthermore, Kubernetes UIDs are UUIDs as standardized by <a href="https://www.itu.int/ITU-T/studygroups/com17/oid.html">ISO/IEC 9834-8 and ITU-T X.667. Which states:

- If generated according to one of the mechanisms defined in Rec.
- ITU-T X.667 | ISO/IEC 9834-8, a UUID is either guaranteed to be different from all other UUIDs generated before 3603 A.D., or is extremely likely to be different (depending on the mechanism chosen). - Therefore, UIDs between clusters should be extremely unlikely to conflict.
