MySQL® 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 update the MySQL® version:

1. Get a list of your MySQL® clusters using this command:

   yc managed-mysql cluster list
   

2. Get information about the cluster you need and check the MySQL® version in the config.version parameter:

   yc managed-mysql cluster get <cluster_name_or_ID>
   

3. Run the MySQL® upgrade:

   yc managed-mysql cluster update <cluster_name_or_ID> \
      --mysql-version <new_version_number>
   

The upgrade time depends on multiple factors, e.g., the amount of data or the number of databases in the cluster. The upgrade usually takes several minutes, and 10 minutes or more for large databases.

1. Open the current Terraform configuration file with an infrastructure plan.

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

2. Add the version field to the yandex_mdb_mysql_cluster resource or change the field value if it already exists:

   resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
      ...
      version = "<MySQL®_version>"
      ...
   }
   

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_mysql_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 make a 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-mysql/v1/clusters/<cluster_ID>' \
      --data '{
                "updateMask": "configSpec.version",
                "configSpec": {
                  "version": "<MySQL®_version>"
                }
              }'
   

   Where:

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

     In this case, only one parameter is provided.

   • configSpec.version: New MySQL® version.

   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 make a 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>",
           ...
           "<setting_N>"
       ]
   }
   

   grpcurl \
      -format json \
      -import-path ~/cloudapi/ \
      -import-path ~/cloudapi/third_party/googleapis/ \
      -proto ~/cloudapi/yandex/cloud/mdb/mysql/v1/cluster_service.proto \
      -rpc-header "Authorization: Bearer $IAM_TOKEN" \
      -d '{
            "cluster_id": "<cluster_ID>",
            "update_mask": {
              "paths": [
                "config_spec.version"
              ]
            },
            "config_spec": {
              "version": "<MySQL®_version>"
            }
          }' \
      mdb.api.cloud.yandex.net:443 \
      yandex.cloud.mdb.mysql.v1.ClusterService.Update
   

   Where:

   • update_mask: List of parameters to update as an array of paths[] strings.

     In this case, only one parameter is provided.

   • config_spec.version: New MySQL® version.

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

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

1. Open the current Terraform configuration file with an infrastructure plan.

2. In the version field, specify the 8.0 value in the yandex_mdb_mysql_cluster resource:

   resource "yandex_mdb_mysql_cluster" "<cluster_name>" {
      ...
      version = "8.0"
      ...
   }
   

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.
