of maintenance updates and maintenance windows, see Maintenance policy.
Set a preferred window for maintenance on an instance
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for Redis
Click the instance ID of the instance you want to set a maintenance window
for.
Click Edit.
Under the Maintenance section, select the desired day and time for the
maintenance window. The time is set in your local time zone.
Click Save.
gcloud
Run the following command to set a maintenance window for a Redis instance:
In the row for Memorystore, toggle the email button to ON.
A maintenance notification email uses the title, "Upcoming maintenance for your
Cloud Memorystore instance [your-instance-name]". Each email address that
needs to receive notifications must opt in separately.
Maintenance notifications are set at the project level rather than on instances.
Email notifications are sent to the email address associated with your Google
account. It is not possible to configure a custom email alias (for instance, a
team email alias).
Find scheduled maintenance
If maintenance has been scheduled for your instance, you can view it using the
following instructions:
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for Redis
Click the instance ID of the instance that you want to view scheduled
maintenance for.
Under the Maintenance section, you can view the date and time of any
scheduled maintenance updates.
Choose between Update now, Defer to next scheduled window, and
Custom day and time. For more information, see the overview of rescheduling maintenance.
If you want to update your instance immediately, select Update now
and click Update.
If you want to delay the scheduled maintenance by one week, select
Defer to the next scheduled window and click Reschedule.
If you want to designate a specific time, select Custom day and time,
choose the new time, and click Reschedule.
REGION is the region where your instance is located
RESCHEDULE_TYPE is the type of rescheduled update. Available values are:
IMMEDIATE: Starts the maintenance update immediately
NEXT_AVAILABLE_WINDOW: Defers maintenance until the next maintenance
window. The next window is one week from the window in which maintenance
was originally scheduled
SPECIFIC_TIME: Allows you to designate a specific time for the update.
The rescheduled time must be no more than seven days from time of the
original maintenance window
RESHEDULE_TIME You can only specify this value if you set --reschedule-type to SPECIFIC TIME. This value uses the ISO 1801 format. For example, 2020-01-16T16:56:00.000Z. The time is set in UTC time.
