Fields
name

string

Required. Unique name of the resource in this scope including project and location using the form: projects/{projectId}/locations/{locationId}/instances/{instanceId}

Note: Redis instances are managed and addressed at regional level so locationId here refers to a GCP region; however, users may choose which specific zone (or collection of zones for cross-zone instances) an instance should be provisioned in. Refer to locationId and alternativeLocationId fields for more details.

displayName

string

An arbitrary and optional user-provided name for the instance.

labels

map (key: string, value: string)

Resource labels to represent user provided metadata

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

locationId

string

Optional. The zone where the instance will be provisioned. If not provided, the service will choose a zone from the specified region for the instance. For standard tier, additional nodes will be added across multiple zones for protection against zonal failures. If specified, at least one node will be provisioned in this zone.

alternativeLocationId

string

Optional. If specified, at least one node will be provisioned in this zone in addition to the zone specified in locationId. Only applicable to standard tier. If provided, it must be a different zone from the one provided in [locationId]. Additional nodes beyond the first 2 will be placed in zones selected by the service.

If not provided, the service will choose an unused /29 block, for example, 10.0.0.0/29 or 192.168.0.0/29. For READ_REPLICAS_ENABLED the default block size is /28.

secondaryIpRange

string
