Self-service maintenance

This page describes self-service maintenance, which lets you accept a maintenance update on your cluster outside of the typical flow of scheduled maintenance. To see which vulnerabilities are addressed by each self-service maintenance update, see Memorystore for Redis Cluster maintenance changelogs.

Overview

Memorystore for Redis Cluster releases software improvements regularly, such as patches for known vulnerabilities, through new maintenance versions. Although Memorystore for Redis Cluster schedules maintenance updates once every few months to ensure that you have the latest maintenance version, you might want to use self-service maintenance if any of the following conditions apply:

  • 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 update to the latest version manually. You can let Memorystore for Redis Cluster update your maintenance version automatically during your next scheduled maintenance event.

Impact of self-service maintenance

Self-service maintenance updates have the same impact on your applications as standard maintenance updates. For more information, see About maintenance.

View maintenance versions

You can use either the Google Cloud console or the gcloud CLI to view the following information about maintenance versions that are associated with your cluster:

  • The current maintenance version.

  • Available maintenance versions to which you can update your cluster.

Console

  1. In the Google Cloud console, go to the Memorystore for Redis Cluster page.

    Memorystore for Redis Cluster

  2. Click the cluster about which you want to view maintenance version information.

  3. On the Cluster at a glance page, scroll until the Maintenance card appears.

    Next to the Maintenance version field, the current maintenance version appears. Also, if there are available maintenance versions to which you can update the cluster, then the Update available status appears next to the Self-service maintenance field. If the No updates are available status appears, then the cluster has the latest version.

gcloud

To view maintenance version information about your cluster, use the gcloud redis clusters describe command.

gcloud redis clusters describe CLUSTER_ID /
--region=REGION_NAME /
--project=PROJECT_NAME

Make the following replacements:

  • CLUSTER_ID: the ID of the cluster
  • REGION_NAME: the region name for the cluster
  • PROJECT_NAME: the name of the Google Cloud project that contains the cluster

The current maintenance version appears next to the effectiveMaintenanceVersion field. Also, the list of available maintenance versions appears next to the availableMaintenanceVersions field. If no versions appear, then your cluster has the latest version.

Update your cluster to a new maintenance version

You can use either the Google Cloud console or the gcloud CLI to update your cluster to a newer maintenance version.

Console

  1. In the Google Cloud console, go to the Memorystore for Redis Cluster page.

    1. From the Choose maintenance version menu, select the maintenance version to which you want to update the cluster.
    2. Click Apply.

gcloud

To update the maintenance version for your cluster, use the gcloud redis clusters update command.

gcloud redis clusters update CLUSTER_ID /
--region=REGION_NAME /
--project=PROJECT_NAME /
--maintenance-version=MAINTENANCE_VERSION

Make the following replacements:

  • CLUSTER_ID: the ID of the cluster.
  • REGION_NAME: the region name for the cluster.
  • PROJECT_NAME: the name of the Google Cloud project that contains the cluster.
  • MAINTENANCE_VERSION: the maintenance version to which you want to update the cluster. To find available maintenance versions, see View maintenance versions.
