To remove a VM created with Terraform from a placement group:
-
Open the VM configuration file and delete the
placement_group_id
parameter.Here is an example of the VM configuration file structure:
... resource "yandex_compute_instance" "vm-1" { name = "my-vm" platform_id = "standard-v3" placement_policy { placement_group_id = "${yandex_compute_placement_group.group1.id}" } } resource "yandex_compute_placement_group" "group1" { name = "test-pg" } ...
-
In the command line, go to the directory with the Terraform configuration file.
-
Check the configuration using this command:
terraform validate
If the configuration is correct, you will get this message:
Success! The configuration is valid.
-
Run this command:
terraform plan
The terminal will display a list of resources with their parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.
-
Apply the configuration changes:
terraform apply
-
Confirm the changes: type
yes
into the terminal and press Enter.You can check the changes in the management console
.
Use the update REST API method for the Instance resource or the InstanceService/Update gRPC API call.
