ClickHouse® version upgrade

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

To get a list of available versions, run this command:

yc managed-clickhouse version list

1. Get an IAM token for API authentication and set it as an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Call the Versions.List method, e.g., via the following cURL request:

   curl \
       --request GET \
       --header "Authorization: Bearer $IAM_TOKEN" \
       --url 'https://mdb.api.cloud.yandex.net/managed-clickhouse/v1/versions'
   

3. View the server response to make sure your request was successful.

1. Get an IAM token for API authentication and set it as an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Clone the cloudapi repository:

   cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
   

   Below, we assume the repository contents are stored in the ~/cloudapi/ directory.

3. Use the VersionsService.List call and send the following request, e.g., via gRPCurl:

   grpcurl \
       -format json \
       -import-path ~/cloudapi/ \
       -import-path ~/cloudapi/third_party/googleapis/ \
       -proto ~/cloudapi/yandex/cloud/mdb/clickhouse/v1/versions_service.proto \
       -rpc-header "Authorization: Bearer $IAM_TOKEN" \
       mdb.api.cloud.yandex.net:443 \
       yandex.cloud.mdb.clickhouse.v1.VersionsService.List
   

4. View the server response to make sure your request was successful.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

1. Get a list of your ClickHouse® clusters and view their versions:

   yc managed-clickhouse cluster list
   
   +----------------------+------+-------------+---------+---------------------+--------+---------+
   |          ID          | NAME | ENVIRONMENT | VERSION |     CREATED AT      | HEALTH | STATUS  |
   +----------------------+------+-------------+---------+---------------------+--------+---------+
   | c9qf1kmm0ebi******** | mych | PRODUCTION  |    23.8 | 2024-06-06 10:23:22 | ALIVE  | RUNNING |
   +----------------------+------+-------------+---------+---------------------+--------+---------+
   

2. Upgrade the ClickHouse® version for the cluster you need:

   yc managed-clickhouse cluster update --id <cluster_ID> --version <ClickHouse®_version>
   

   Specify the ClickHouse® version: 24.8, 25.3, 25.4, 25.5, or 25.6.

As soon as you run the upgrade, the cluster status will switch to UPDATING. Wait for the operation to complete and then check the cluster version.

1. Open the current Terraform configuration file describing your infrastructure.

   For information on how to create this file, see Creating a cluster.

2. Add the version field to the Managed Service for ClickHouse® cluster description or edit its value if it is already there:

   resource "yandex_mdb_clickhouse_cluster" "<cluster_name>" {
     ...
     version = "<ClickHouse®_version>"
   }
   

   Specify the ClickHouse® version: 24.8, 25.3, 25.4, 25.5, or 25.6.

3. Make sure the settings are correct.

   1. In the command line, navigate to the directory that contains the current Terraform configuration files defining the infrastructure.

   2. Run this command:

      terraform validate
      

      Terraform will show any errors found in your configuration files.

4. Confirm updating the resources.

   1. Run this command to view the planned changes:

      terraform plan
      

      If you described the configuration correctly, the terminal will display a list of the resources to update and their parameters. This is a verification step that does not apply changes to your resources.

   2. If everything looks correct, apply the changes:

      1. Run this command:

         terraform apply
         

      2. Confirm updating the resources.

      3. Wait for the operation to complete.

For more information, see this Terraform provider guide.

resource "yandex_mdb_clickhouse_cluster" "<cluster_name>" {
  ...
  timeouts {
    create = "1h30m" # 1 hour 30 minutes
    update = "2h"    # 2 hours
    delete = "30m"   # 30 minutes
  }
}

1. Get an IAM token for API authentication and save it as an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Call the Cluster.Update method, e.g., via the following cURL request:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the updateMask parameter as a single comma-separated string.

   curl \
       --request PATCH \
       --header "Authorization: Bearer $IAM_TOKEN" \
       --header "Content-Type: application/json" \
       --url 'https://mdb.api.cloud.yandex.net/managed-clickhouse/v1/clusters/<cluster_ID>' \
       --data '{
                 "updateMask": "configSpec.version",
                 "configSpec": {
                   "version": "<ClickHouse®>_version"
                 }
               }'
   

   Where:

   • updateMask: Comma-separated list of settings you want to update.

     Here, we only specified a single parameter, configSpec.version.

   • configSpec.version: target ClickHouse® version, 24.8, 25.3, 25.4, 25.5, or 25.6.

   You can request the cluster ID with the list of clusters in the folder.

   export IAM_TOKEN="<IAM_token>"

3. Use the ClusterService.Update call and send the following request, e.g., via gRPCurl:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the update_mask parameter as an array of paths[] strings.

   Format for listing settings

   "update_mask": {
       "paths": [
           "<setting_1>",
           "<setting_2>",

   • update_mask: List of settings you want to update as an array of strings (paths[]).

     Here, we only specified a single parameter, config_spec.version.

   • config_spec.version: target ClickHouse® version, 24.8, 25.3, 25.4, 25.5, or 25.6.

   You can request the cluster ID with the list of clusters in the folder.
