$ terraform apply
╷
│ Warning: Provider development overrides are in effect
│ 
│ The following provider development overrides are set in the CLI configuration:
│  - scaleway/scaleway in /Users/sieben/workspace/terraform-provider-scaleway
│ 
│ The behavior may therefore not match any released version of the provider and applying changes may cause the state to become incompatible with published releases.
╵

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # scaleway_baremetal_server.main will be created
  + resource "scaleway_baremetal_server" "main" {
      + domain          = (known after apply)
      + id              = (known after apply)
      + ips             = (known after apply)
      + name            = (known after apply)
      + offer           = "EM-L101X-SATA"
      + offer_id        = (known after apply)
      + organization_id = (known after apply)
      + os              = "d17d6872-0412-45d9-a198-af82c34d3c5c"
      + os_id           = (known after apply)
      + project_id      = (known after apply)
      + ssh_key_ids     = [
          + "495d0e9f-a22b-4ff5-8324-0cb4746c57dc",
        ]
      + zone            = "fr-par-2"

      + timeouts {
          + create = "10s"
        }
    }

Plan: 1 to add, 0 to change, 0 to destroy.
