DESCRIPTION
    (ALPHA) Update the metadata and/or configuration parameters of a Redis
    instance.

    This command can fail for the following reasons:
      ▪ The instance specified does not exist.
      ▪ The active account does not have permission to update the given
        instance.

EXAMPLES
    To update a Redis instance with the name my-redis-instance to have the
    display name "Cache for Foo Service", and add the two labels, env and
    service, run:

        $ gcloud alpha redis instances update my-redis-instance \
            --display-name="Cache for Foo Service" \
            --update-labels=env=test,service=foo

POSITIONAL ARGUMENTS
     Instance resource - Arguments and flags that specify the Memorystore Redis
     instance you want to update. The arguments in this group can be used to
     specify the attributes of this resource. (NOTE) Some attributes are not
     given arguments in this group but can be set in other ways.

     To set the project attribute:
      ◆ provide the argument instance on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       INSTANCE
          ID of the instance or fully qualified identifier for the instance.

          To set the instance attribute:
          ▸ provide the argument instance on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --region=REGION
          The name of the Redis region of the instance. Overrides the default
          redis/region property value for this command invocation.

          To set the region attribute:
          ▸ provide the argument instance on the command line with a fully
            specified name;
          ▸ provide the argument --region on the command line;
          ▸ set the property redis/region.

FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

     --display-name=DISPLAY_NAME
        A human-readable name for the instance.

     --enable-auth
        Enables Redis AUTH for the instance.

     --maintenance-version=MAINTENANCE_VERSION
        Specifies which maintenance version to apply to your instance during
        self-service maintenance. To view the available maintenance versions
        for your instance, run gcloud redis instances describe [INSTANCE_ID].
        Acceptable values for this flag are either current_default or one of
        the specific versions listed by the describe command. If you pass the
        value current_default, the Memorystore updates to the most recent
        available maintenance version during self service maintenance.

     --persistence-mode=PERSISTENCE_MODE
        Operation mode for automated persistence. PERSISTENCE_MODE must be one
        of:

         disabled
            RDB mode is disabled
         rdb
            Automatic RDB persistence

     --rdb-snapshot-period=RDB_SNAPSHOT_PERIOD
        The attempted period between RDB snapshots. RDB_SNAPSHOT_PERIOD must be
        one of:

         12h
            12 hours
         1h
            1 hour
         24h
            24 hours
         6h
            6 hours

     --rdb-snapshot-start-time=RDB_SNAPSHOT_START_TIME
        Date and time of the first snapshot in the ISO 1801 format, and
        alignment time for future snapshots. For example, 2022-11-02T03:00:00Z.

     --read-replicas-mode=READ_REPLICAS_MODE
        Read replicas mode used by the instance. Only works against standard
        tier instances with 5GB and above provisioned capacity and Redis
        version 5.0 and above. This is an irreversible update i.e. Read
        replicas can not be disabled for the instance once it is enabled. Also
        this update is exclusive and cannot be clubbed with other update
        operations. READ_REPLICAS_MODE must be one of:

         read-replicas-disabled
            If read replica is not enabled on the instance, no changes are
            done. If read replica is enabled for the instance, update operation
            fails

         read-replicas-enabled
            Read replica is enabled for the instance if not already enabled.
            Read endpoint will be provided and the instance can scale up and
            down the number of replicas.

     --remove-redis-config=[KEY,...]
        A list of Redis config parameters to remove. Removing a non-existent
        config parameter is silently ignored.

     --replica-count=REPLICA_COUNT
        The replica count of the instance. Valid from 0 to 5.

     --secondary-ip-range=SECONDARY_IP_RANGE
        Required only when read-replicas-mode is enabled on the instance. The
        CIDR range of internal addresses that are reserved for this instance.
        For example, 10.0.0.0/28 or 192.168.0.0/28. Range must be unique and
        non-overlapping with existing ranges in the network. If value 'auto'
        passed, the service will automatically pick an available range.

     --size=SIZE
        The memory size of the instance in GiB.

     --update-labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to update. If a label exists, its value
        is modified. Otherwise, a new label is created.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must
        contain only hyphens (-), underscores (_), lowercase characters, and
        numbers.

     --update-redis-config=KEY=VALUE
        A list of Redis config KEY=VALUE pairs to update according to
        http://cloud.google.com/memorystore/docs/reference/redis-configs. If a
        config parameter is already set, its value is modified; otherwise a new
        Redis config parameter is added. Currently, the only supported
        parameters are:

        Redis version 3.2 and newer: maxmemory-policy, notify-keyspace-events,
        timeout.

        Redis version 4.0 and newer: activedefrag, lfu-decay-time,
        lfu-log-factor, maxmemory-gb.

        Redis version 5.0 and newer: stream-node-max-bytes,
        stream-node-max-entries.

        Redis version 7.0 and newer: maxmemory-clients, lazyfree-lazy-eviction,
        lazyfree-lazy-expire, lazyfree-lazy-user-del, lazyfree-lazy-user-flush.

     At most one of these can be specified:

       --clear-labels
          Remove all labels. If --update-labels is also specified then
          --clear-labels is applied first.

          For example, to remove all labels:

              $ gcloud alpha redis instances update --clear-labels

          To remove all existing labels and create two new labels, foo and baz:

              $ gcloud alpha redis instances update --clear-labels \
                --update-labels foo=bar,baz=qux

       --remove-labels=[KEY,...]
          List of label keys to remove. If a label does not exist it is
          silently ignored. If --update-labels is also specified then
          --update-labels is applied first.

     At most one of these can be specified:

       --maintenance-window-any
          Removes the user-specified maintenance window.

       Or at least one of these can be specified:

         --maintenance-window-day=MAINTENANCE_WINDOW_DAY
            Day of week for maintenance window, in UTC time zone.
            MAINTENANCE_WINDOW_DAY must be one of: SUNDAY, MONDAY, TUESDAY,
            WEDNESDAY, THURSDAY, FRIDAY, SATURDAY. MAINTENANCE_WINDOW_DAY must
            be one of: day-of-week-unspecified, friday, monday, saturday,
            sunday, thursday, tuesday, wednesday.

         --maintenance-window-hour=MAINTENANCE_WINDOW_HOUR
            Hour of day (0 to 23) for maintenance window, in UTC time zone.

API REFERENCE
    This command uses the redis/v1alpha1 API. The full documentation for this
    API can be found at: https://cloud.google.com/memorystore/docs/redis/

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud redis instances update

        $ gcloud beta redis instances update
