CouchbaseScopeGroup Resource
CouchbaseScopeGroup represents a logical unit of data storage that sits between buckets and collections e.g.
a bucket may contain multiple scopes, and a scope may contain multiple collections.
At present, scopes are not nested, so provide only a single level of abstraction.
Scopes provide a coarser grained basis for role-based access control (RBAC) and cross-datacenter replication (XDCR) than collections, but finer that buckets.
In order to be considered by the Operator, a scope must be referenced by either a CouchbaseBucket or CouchbaseEphemeralBucket resource.
Unlike CouchbaseScope resources, scope groups represents multiple scopes, with the same common set of collections, to be expressed as a single resource, minimizing required configuration and Kubernetes API traffic.
It also forms the basis of Couchbase RBAC security boundaries.
The following is an example resource, depicting the overall structure and any defaults (consult the field reference for valid values for "empty" values, such as empty strings etc.):
apiVersion: v2
kind: CouchbaseScopeGroup
metadata:
name: ""
spec:
collections:
managed: false
preserveDefaultCollection: false
resources:
- kind: CouchbaseCollection
name: ""
selector: {}
names:
- ""couchbasescopegroups.apiVersion
Description
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources.
couchbasescopegroups.kind
Description
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds.
couchbasescopegroups.metadata
Description
Standard object metadata as defined for all Kubernetes types.
For additional details see the Kubernetes reference documentation.
couchbasescopegroups.metadata.name
Description
The name of a resource. This must be unique for the kind of resource within the namespace.
All resources must have a name.
The name may be omitted and metadata.generateName used instead to generate a unique resource name.
For additional details on resource names, see the Kubernetes reference documentation.
couchbasescopegroups.metadata.namespace
Description
The namespace the resource resides in. All resources reside in a namespace.
The namespace is optional and may be specified in YAML configuration to override the namespace supplied by kubectl.
For additional details on namespaces, see the Kubernetes reference documentation.
couchbasescopegroups.metadata.labels
Description
Labels allow resources to be labeled with key/value pairs of data. Labels are indexed and allow resources to be selected based upon specified labels.
Labels are relevant for certain types when using label selection within your resources.
For additional details on labels and selectors, see the Kubernetes reference documentation.
couchbasescopegroups.metadata.annotations
Description
Annotations allow resources to be annotated with key/value pairs of data. Annotations are arbitrary, and not indexed, so cannot be used to select resources, however may be used to add context or accounting to your resources.
For additional details on annotations, see the Kubernetes reference documentation.
couchbasescopegroups.spec
couchbasescopegroups.spec.collections.preserveDefaultCollection
Description
PreserveDefaultCollection indicates whether the Operator should manage the default collection within the default scope.
The default collection can be deleted, but can not be recreated by Couchbase Server.
By setting this field to true, the Operator will implicitly manage the default collection within the default scope.
The default collection cannot be modified and will have no document time-to-live (TTL).
When set to false, the operator will not manage the default collection, which will be deleted and cannot be used or recreated.
couchbasescopegroups.spec.collections.resources.kind
couchbasescopegroups.spec.collections.resources.name
couchbasescopegroups.spec.collections.selector
Description
Selector allows resources to be implicitly considered for inclusion in this scope or scopes. More info: https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.21/#labelselector-v1-meta.
couchbasescopegroups.spec.names
Constraints
Required
Type: []string
Minimum Length: 1
Maximum Length: 251
Pattern (Regular Expression): ^[a-zA-Z0-9\-][a-zA-Z0-9\-%_]\{0,250}$
Description
Names specifies the names of the scopes. Unlike CouchbaseScope, which specifies a single scope, a scope group specifies multiple, and the scope group must specify at least one scope name. Any scope names specified must be unique. Scope names must be 1-251 characters in length, contain only [a-zA-Z0-9_-%] and not start with either _ or %.
