Can 1 namespace span across multiple EKS clusters?
I am trying to understand the relation between namespaces and clusters in EKS. Can 1 namespace span across multiple EKS clusters? Is that possible?
Kubernetes supports multiple virtual clusters backed by the same physical cluster. These virtual clusters are called namespaces.
Kubernetes concepts
So, no, a namespace can not span across multiple Kubernetes clusters. You can have namespaces with the same name in multiple clusters. But those would be different objects as a namespace is defined on the cluster level.
