ClickHouse® version upgrade

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 get a list of available versions, run the following command:

yc managed-clickhouse version list

1. Get an IAM token for API authentication and put it into the environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Use the Versions.List method and send the following request, e.g., via cURL:

   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 the request was successful.

1. Get an IAM token for API authentication and put it into the 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 the request was successful.

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.

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. Update the ClickHouse® version for any cluster as needed:

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

   Specify the ClickHouse® version: 24.3, 24.8, 24.9, or 24.10.

When the update starts, 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 with an infrastructure plan.

   For more information about creating this file, see Creating clusters.

2. To the Managed Service for ClickHouse® cluster description, add the version field or change its value if it is already there:

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

   Specify the ClickHouse® version: 24.3, 24.8, 24.9, or 24.10.

3. Make sure the settings are correct.

   1. Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.

   2. Run the command:

      terraform validate
      

      If there are errors in the configuration files, Terraform will point to them.

4. Confirm updating the resources.

   1. 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.

   2. If you are happy with the planned changes, apply them:

      1. Run the command:

         terraform apply
         

      2. Confirm the update of resources.

      3. Wait for the operation to complete.

For more information, see the Terraform provider documentation.

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 put it into the environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Use the Cluster.Update method and send the following request, e.g., via cURL:

   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: List of parameters to update as a single string, separated by commas.

     Here only one parameter is specified: configSpec.version.

   • configSpec.version: target ClickHouse® version, 24.3, 24.8, 24.9, or 24.10.

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

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

1. Get an IAM token for API authentication and put it into the 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 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>",
           ...

                 "config_spec.version"
               ]
             },
             "config_spec": {
               "version": "<ClickHouse®>_version"

   • config_spec.version: target ClickHouse® version, 24.3, 24.8, 24.9, or 24.10.

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