array of
NamespaceManagementClustersMessage
kubernetes_status_messages
Required
Current set of messages associated with the object.
array of
string

Optional
Disclaimer to be displayed prior to login via the Kubectl plugin. If unset, just skip it.
array of
string
master_DNS
Optional
List of DNS server IP addresses to use on Kubernetes API server, specified in order of preference.
array of
string
