Creating an instance group based on a YAML specification
In Instance Groups, all operations are performed under a service account. If you don't have a service account, create one.
To be able to create, update, and delete VM instances in the instance group, assign the compute.editor role to the service account.
If you want to integrate an instance group with a Yandex Network Load Balancer, you also need to assign the load-balancer.editor role to the service account.
To integrate an instance group with an L7 load balancer from Yandex Application Load Balancer, assign the alb.editor role to the service account.
To create an instance group based on a YAML specification:
If you do not have the Yandex Cloud CLI yet, install and initialize it.
The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.
Run this command:
yc compute instance-group create --file specification.yaml
For more information about the yc compute instance-group create command, see the CLI reference.
Use the InstanceGroupService/CreateFromYaml gRPC API call or the createFromYaml method of the REST API InstanceGroup resource.
