Managing host aliases
You can assign each Managed Service for MySQL® cluster host an alias, which is a custom network name. An alias is mapped to a specific DNS record which always points to the host associated with the alias. This allows you to access the cluster using a human-readable name without the host’s internal FQDN. An alias must be unique within a folder. You can assign only one alias per host.
Alias format:
h-<alias_name>-my-<folder_ID>.rw.mdb.yandexcloud.net
Note
When creating an alias, you only need to specify its name.

To get a list of aliases, you need the managed-mysql.viewer role or higher for the folder.
