Manage connection profiles using the API

MySQL | PostgreSQL | PostgreSQL to AlloyDB

Overview

In this page, you learn how to use the Database Migration Service API to manage connection profiles for a MySQL source database.

There are two ways that you can use the Database Migration Service API. You can make REST API calls or you can use the Google Cloud CLI (CLI).

Create a connection profile for Cloud SQL for MySQL destination

The following shows a request to create a connection profile for a Cloud SQL for MySQL destination. Database Migration Service uses the information in this request to create a new Cloud SQL for MySQL instance.

REST

Before using any of the request data, make the following replacements:

project-id: The project ID
region: The project region
connection-profile-id: The connection profile ID
connection-profile-display-name: The connection profile display name
database-version: The database version. For example, MYSQL_5_7.
tier: The machine type. For example, db-custom-1-4096.
data-disk-type: The data disk type. For example, PD_SSD.
data-disk-size-gb: The data disk size, in Gb. For example, 20.
zone: The zone in the project region
cmek_key_name: Optional: The full path and name of a customer-managed encryption key (CMEK). For example, "projects/project-id/locations/location/keyRings/ring/cryptoKeys/customer-managed-encryption-key".

All data stored within Google Cloud is encrypted at rest using the same hardened key management systems that we use for our own encrypted data. These key-management systems provide strict key access controls and auditing, and encrypt user data at rest using AES-256 encryption standards. No setup, configuration, or management is required. Google Cloud's default encryption at rest is the best choice for users who don't have specific requirements related to compliance or locality of cryptographic material.

If you need more control over the keys used to encrypt data at rest within a Google Cloud project, then Database Migration Service offers the ability to protect your data using encryption keys managed by you within Cloud Key Management Service (KMS). These encryption keys are called customer-managed encryption keys (CMEK). When you protect data in Database Migration Service with CMEK, the CMEK is within your control.

The cmek_key_name parameter is associated with having a CMEK that Database Migration Service can use to encrypt data that's migrated from the source to the destination. The CMEK is represented by the customer-managed-encryption-key placeholder.

The ring placeholder represents the key ring for your CMEK. A key ring organizes keys in a specific Google Cloud location and allows you to manage access control on groups of keys. A key ring's name doesn't need to be unique across a Google Cloud project, but must be unique within a given location. For more information about key rings, see Cloud KMS resources.

As part of creating the connection profile, Database Migration Service will verify that the CMEK exists, and that Database Migration Service has permissions to use the key.

If either of these conditions aren't met, then the following error message will be returned:

CMEK_DOES_NOT_EXIST_OR_MISSING_PERMISSIONS

To resolve this issue, verify that the key that you provided exists, and that the Database Migration Service service account has the cloudkms.cryptoKeys.get permission for the key.

If you prefer to use Google Cloud's internal key management system instead of a CMEK to encrypt your data, then don't include the cmek_key_name parameter and value in your API request.

Delete a connection profile

Important: You can delete a connection profile only if there are no active migration jobs associated with the profile. If a connection profile has active migration jobs, then promote or delete the jobs.

To see whether a connection profile has any active migration jobs associated with it, run the following command:

GET https://datamigration.googleapis.com/v1/projects/project-id/locations/region/migrationJobs?filter=state:STATE_NAME OR state:STATE_NAME AND source:projects/project-id/locations/region/connectionProfiles/connection-profile-id

For example:

GET https://datamigration.googleapis.com/v1/projects/myproject/locations/myregion/migrationJobs?filter=state:RUNNING OR state:FAILED AND source:projects/myproject/locations/myregion/connectionProfiles/mysql-src1

The various states (statuses) of the migration job are:

NOT STARTED: The migration job is created, but it hasn't been started.
STARTING: The migration job is in the process of being started.
RUNNING: The migration job is running and can be used to migrate data from the source database to the destination database.
STOPPING: The migration job is in the process of being stopped.
STOPPED: The migration job is paused, and is no longer migrating data to the destination database.
RESUMING: The paused migration job is running.
FAILED: A problem occurred while the migration job was running.
RESTARTING: Database Migration Service takes a new snapshot of the source database, loads the initial dump into the destination database, and processes ongoing changes of data from the source database to the destination database.

If a user has a migration job in any of these statuses, and if the user attempts to delete the connection profile, then it will fail.

REST

Before using any of the request data, make the following replacements:

project-id: The project ID
region: The project region
