Updating Redis cluster settings
After creating a cluster, you can:
-
Configure Redis servers as described in the Redis documentation
. For a list of supported settings, see Redis settings and the API reference. -
Enable sharding in a non-sharded cluster.
-
Move a cluster to another folder.

Changing the cluster name and description
- In the management console
, select the folder with the cluster you need. - Select Managed Service for Redis.
- Select the cluster you need.
- At the top of the page, click Edit.
- Under Basic parameters, enter a new name and description for the cluster.
- Click Save changes.
If you do not have the Yandex Cloud command line interface yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name
or --folder-id
parameter.
To change the host class for the cluster:
-
View a description of the update cluster CLI command:
yc managed-redis cluster update --help
-
Specify a new name and description in the cluster update command:
yc managed-redis cluster update <cluster_name_or_ID> \ --new-name <new_cluster_name> \ --description <new_cluster_description>
Alert
Do not change the cluster name using Terraform. This will delete the existing cluster and create a new one.
To update the cluster description:
-
Open the current Terraform configuration file with an infrastructure plan.
For more information about creating this file, see Creating clusters.
-
In the Managed Service for Redis cluster description, change the
description
parameter value:resource "yandex_mdb_redis_cluster" "<cluster_name>" { name = "<cluster_name>" description = "<new_cluster_description>" ... }
-
Make sure the settings are correct.
-
Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.
-
Run the command:
terraform validate
If there are errors in the configuration files, Terraform will point to them.
-
-
Confirm updating the resources.
-
Run the command to view planned changes:
terraform plan
If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.
-
If you are happy with the planned changes, apply them:
-
Run the command:
terraform apply
-
Confirm the update of resources.
-
Wait for the operation to complete.
-
-
For more information, see the Terraform provider documentation
Time limits
A Terraform provider sets the timeout for Managed Service for Redis cluster operations:
- Creating a cluster, including by restoring one from a backup: 15 minutes.
- Editing a cluster: 60 minutes.
- Deleting a cluster: 15 minutes.
Operations exceeding the set timeout are interrupted.
How do I change these limits?
Add the timeouts
block to the cluster description, for example:
resource "yandex_mdb_redis_cluster" "<cluster_name>" {
...
timeouts {
create = "1h30m" # 1 hour 30 minutes
update = "2h" # 2 hours
delete = "30m" # 30 minutes
}
}
To change a cluster's name and description, use the update REST API method for the Cluster resource or the ClusterService/Update gRPC API call and provide the following in the request:
- Cluster ID in the
clusterId
parameter. To find out the cluster ID, get a list of clusters in the folder. - New cluster name in the
name
parameter. - New cluster description in the
description
parameter. - List of fields to update (in this case,
name
anddescription
) in theupdateMask
parameter.
Warning
This API method overrides all parameters of the object being modified that were not explicitly passed in the request to the default values. To avoid this, list the settings you want to change in the updateMask
parameter (one line separated by commas).
Configuring the use of FQDNs instead of IP addresses
If the relevant setting is disabled (by default), Redis uses IP addresses as host addresses. If this setting is enabled, it will replace the host's IP address with its FQDN. For more information about this setting and its uses, see Using FQDNs instead of IP addresses.
Note
Some clients do not support this setting and will fail to connect to the cluster hosts. Such clients expect an IP address and will produce errors if you provide an FQDN instead.
To enable or disable the use of FQDNs instead of IP addresses:
- In the management console
, select the folder with the cluster you need. - Select Managed Service for Redis.
- Select the cluster you need.
- At the top of the page, click Edit.
- Under Basic parameters, enable or disable Use FQDN instead of IP addresses.
- Click Save changes.
If you do not have the Yandex Cloud command line interface yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name
or --folder-id
parameter.
To enable or disable the use of FQDNs instead of IP addresses:
-
View a description of the update cluster CLI command:
yc managed-redis cluster update --help
-
Provide the required setting value in the update cluster command:
yc managed-redis cluster update <cluster_name_or_ID> \ --announce-hostnames <using_FQDNs_instead_of_IP_addresses>
--announce-hostnames
: Enables or disables using FQDNs instead of IP addresses:true
orfalse
.You can get the cluster name and ID with a list of clusters in the folder.
To enable or disable the use of FQDNs instead of IP addresses:
-
Open the current Terraform configuration file with an infrastructure plan.
For more information about creating this file, see Creating clusters.
-
In the Managed Service for Redis cluster description, change the
announce_hostnames
parameter value:resource "yandex_mdb_redis_cluster" "<cluster_name>" { name = "<cluster_name>" ... announce_hostnames = <using_FQDNs_instead_of_IP_addresses> ... }
announce_hostnames

Changing the host class
When changing the host class:
- Your single-host cluster will be unavailable for a few minutes with database connections terminated.
- In a non-sharded multiple-host cluster:
- The master will change. Its hosts will be stopped and updated one by one. Once stopped, a host will be unavailable for a few minutes.
- Using a special FQDN does not guarantee a stable database connection: user sessions may be terminated.
- In a sharded cluster:
- The master will change in each multiple-host shard.
- Hosts in each shard will be stopped and updated one at a time. The shard's stopped master host will be unavailable for a few minutes.
- Master host name resolution may not be available. If public access to the host is enabled, you can only connect using the host IP address.
We recommend changing the host class only when the cluster has no active workload.
-
In the management console
, select the folder with the cluster you need. -
