Getting VM metadata

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the command for getting the serial port output:

   yc compute instance get --help
   

2. Select a VM, e.g., first-instance:

   yc compute instance list
   

   Result:

   +----------------------+-----------------+---------------+---------+----------------------+
   |          ID          |       NAME      |    ZONE ID    | STATUS  |     DESCRIPTION      |
   +----------------------+-----------------+---------------+---------+----------------------+
   | fhm0b28lgfp4******** | first-instance  | ru-central1-a | RUNNING | my first vm via CLI  |
   | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI |
   +----------------------+-----------------+---------------+---------+----------------------+
   

3. Get basic information about the VM:

   yc compute instance get first-instance
   

   To get VM information with metadata, use the --full flag:

   yc compute instance get --full first-instance
   

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the documentation on the Terraform website or mirror website.

If you do not have Terraform yet, install it and configure its Yandex Cloud provider.

1. In the Terraform configuration file, define the parameters of the resources you want to create:

   data "yandex_compute_instance" "my_instance" {
     instance_id = "<VM_ID>"
   }
   
   output "instance_external_ip" {
     value = "${data.yandex_compute_instance.my_instance.network_interface.0.nat_ip_address}"
   }
   

   Where:

   • data "yandex_compute_instance": Description of the data source to get VM information from:
     • instance_id: VM ID.
   • output "instance_external_ip": Public IP address of the VM to return in the output:
     • value: Returned value.

   For more information about the yandex_compute_instance data source parameters, see the relevant provider documentation.

2. Create the resources:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

   Terraform will create all the required resources and display the output variable values in the terminal. To check the results, run this command:

   terraform output instance_external_ip
   

   Result:

   instance_external_ip = "158.160.50.228"
   

To get basic information about a VM, use the get REST API method for the Instance resource or the InstanceService/Get gRPC API call.

The basic information does not include any custom metadata provided when creating or updating the VM. To get the information along with the metadata, specify view=FULL in the parameters.
