|
**[1] `k8s.cluster.uid`:** 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
|
|
[ISO/IEC 9834-8 and ITU-T X.667](https://www.itu.int/ITU-T/studygroups/com17/oid.html).
|
|
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.
