I'm trying to make a Kubernetes multi-cluster, and I need a unique value to distinguish between cluster.
Does Kubernetes provide a UID to distinguish each cluster?
If not, is the best way to separate each cluster by the UID of the kube-system namespace?
if you have multi cluster and in each cluster you have multi user and namespace, and you want to handle switching between them, it is better to use kubernetes contexts, https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/ if you just need something unique about cluster, use certificate authority information(ca.crt or ca.key in /etc/kubernetes/pki/ directory). but be careful those files should be secured
