This page describes self-service maintenance, which lets you accept a maintenance update on your instance outside of the normal flow of scheduled maintenance. To see what vulnerabilities are addressed by each self-service maintenance update, see Maintenance changelog.
Overview
Memorystore for Redis regularly releases software improvements, such as patches for known vulnerabilities, through new maintenance versions. While Memorystore for Redis schedules maintenance updates once every few months to ensure you have the latest maintenance version, you might want to use self-service maintenance if:
- You need an update sooner than your next scheduled maintenance event.
- You want to stay up-to-date with CVE patches necessary for FedRAMP Compliance.
You're not required to manually update to the latest version. You can let Memorystore for Redis automatically update your maintenance version during your next scheduled maintenance event.
Impact of self-service maintenance
Self-service maintenance updates have the same impact on your application as standard maintenance update. For more information, see Impact of maintenance.
View your current maintenance version
Check your current maintenance version using the describe command:
gcloud redis instances describe INSTANCE_ID

The maintenance version is indicated beside the maintenanceVersion
attribute.
View available maintenance versions you can update to
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Click your instance ID.
If a maintenance update is available, Update available text is visible in the Maintenance section of the Overview tab.
Click View and Apply.
The Choose Maintenance Version dropdown lists all maintenance versions you can update to.
gcloud
To view available maintenance versions, use the describe command:
gcloud redis instances describe INSTANCE_ID
Replace the following:
- INSTANCE_ID is the ID of your instance
The list of available maintenance versions is indicated beside the
availableMaintenanceVersions attribute. If no versions are listed using this
attribute, then your instance has the latest version.
Update your instance to a new maintenance version
Console
Go to the Memorystore for Redis page in the Google Cloud console.
Click your instance ID.
If a maintenance update is available, Update available text appears in the Maintenance section of the Overview tab.
Click View and Apply.
Select your desired maintenance version from the Choose Maintenance Version dropdown.
Click the Apply button.
gcloud
Use the following method to update your instance to the target maintenance version.
gcloud redis instances update INSTANCE_ID --maintenance-version=MAINTENANCE_VERSION
Replace the following:
- INSTANCE_ID is the ID of your instance
- MAINTENANCE_VERSION is the maintenance version to apply. You can find these values by Viewing available maintenance versions you can update to.
Revert your instance to the current default maintenance update
If for any reason you want to revert from the newest maintenance update version
to the current default version, you can do so using the Google Cloud CLI. For
example, if you update your instance to the newest self-service maintenance
update, and doing this causes an issue/regression with your instance, then you
can revert back to the current default maintenance version with the update
command.
Run the update command and use the value current_default to revert the maintenance
version:
gcloud redis instances update INSTANCE_ID --maintenance-version=current_default
