+<div class="method">
+    <code class="details" id="create">create(parent, body, instanceId=None, x__xgafv=None)</code>
+  <pre>Creates a Redis instance based on the specified tier and memory size.
+
+By default, the instance is accessible from the project's
+[default network](/compute/docs/networks-and-firewalls#networks).
+
+The creation is executed asynchronously and callers may check the returned
+operation to track its progress. Once the operation is completed the Redis
+instance will be fully functional. Completed longrunning.Operation will
+contain the new instance object in the response field.
+
+The returned operation is automatically deleted after a few hours, so there
+is no need to call DeleteOperation.
+
+Args:
+  parent: string, Required. The resource name of the instance location using the form:
+    `projects/{project_id}/locations/{location_id}`
+where `location_id` refers to a GCP region. (required)
+  body: object, The request body. (required)
+    The object takes the form of:
+
+{ # A Google Cloud Redis instance.
+  "labels": { # Resource labels to represent user provided metadata
+    "a_key": "A String",
+  },
+  "displayName": "A String", # An arbitrary and optional user-provided name for the instance.
+  "name": "A String", # Required. Unique name of the resource in this scope including project and
+      # location using the form:
+      #     `projects/{project_id}/locations/{location_id}/instances/{instance_id}`
+      # 
+      # Note: Redis instances are managed and addressed at regional level so
+      # location_id 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 [location_id] and
+      # [alternative_location_id] fields for more details.
+  "alternativeLocationId": "A String", # Optional. Only applicable to STANDARD_HA tier which protects the instance
+      # against zonal failures by provisioning it across two zones. If provided, it
+      # must be a different zone from the one provided in [location_id].
+  "currentLocationId": "A String", # Output only. The current zone where the Redis endpoint is placed. For Basic
+      # Tier instances, this will always be the same as the [location_id]
+      # provided by the user at creation time. For Standard Tier instances,
+      # this can be either [location_id] or [alternative_location_id] and can
+      # change after a failover event.
+  "reservedIpRange": "A String", # Optional. The CIDR range of internal addresses that are reserved for this
+      # instance. If not provided, the service will choose an unused /29 block,

+      # and non-overlapping with existing subnets in an authorized network.
+  "redisVersion": "A String", # Optional. The version of Redis software.
+      # If not provided, latest supported version will be used. Updating the

+      # 
+      #  *   `REDIS_4_0` for Redis 4.0 compatibility
+      #  *   `REDIS_3_2` for Redis 3.2 compatibility (default)
+  "state": "A String", # Output only. The current state of this instance.
+  "createTime": "A String", # Output only. The time the instance was created.
+  "memorySizeGb": 42, # Required. Redis memory size in GiB.
+  "host": "A String", # Output only. Hostname or IP address of the exposed Redis endpoint used by
+      # clients to connect to the service.

+      # transfer data to/from Cloud Storage. Format is
+      # "serviceAccount:<service_account_email>". The value may change over time
+      # for a given instance so should be checked before each import/export
+      # operation.
+  "authorizedNetwork": "A String", # Optional. The full name of the Google Compute Engine
+      # [network](/compute/docs/networks-and-firewalls#networks) to which the

+      # will be used.

+      # http://redis.io/topics/config. Currently, the only supported parameters
+      # are:

+      # different from [location_id].
