- couchbase.com/couchbasememcachedbuckets
- couchbase.com/couchbasereplications
- couchbase.com/couchbaseusers
- couchbase.com/couchbasegroups
- couchbase.com/couchbaserolebindings
- couchbase.com/couchbasebackups
- couchbase.com/couchbasebackuprestores
- couchbase.com/couchbaseautoscalers

Used by the DAC to collect resources associated with a
CouchbaseCluster
. The DAC ensures — when considered as a whole — the configuration is valid for the Couchbase cluster.Required Permissions:

Optional Permissions
- namespaces
-
Used the the DAC to lookup the namespace a cluster is running in. This is used on determine whether the cluster is running on Red Hat OpenShift. This information is used to determine correct defaults for the platform.
