Is there a way to share secrets across namespaces in Kubernetes?

My use case is: I have the same private registry for all my namespaces and I want to avoid creating the same secret for each.

Thanks for your help.

Secret API objects reside in a namespace. They can only be referenced by pods in that same namespace. Basically, you will have to create the secret for every namespace.
