KIND:     Domain
VERSION:  weblogic.oracle/v9

FIELD:    domainUID <string>

DESCRIPTION:
     Domain unique identifier. It is recommended that this value be unique to
     assist in future work to identify related domains in active-passive
     scenarios across data centers; however, it is only required that this value
     be unique within the namespace, similarly to the names of Kubernetes
     resources. This value is distinct and need not match the domain name from
     the WebLogic domain configuration. Defaults to the value of
     `metadata.name`.
