Nic Cope 94a405d179 Add Alias IP and Guest Accelerator support to Instance Templates (#639)
* Move AliasIpRange helpers into utils

To reflect the fact they'll be used by multiple resources.

* Pass Config to build helpers, not meta

It's the only thing meta is used for.

* Refactor getNetwork util methods to return early for the happy path.

* Update compute APIs

compute.Instance.MinCpuPlatform is now GA.

* Fix panic in TestComputeInstanceMigrateState

This seemed to be a pre-existing issue, i.e. I could repro it in master.

* Use only the v1 API for resource_compute_instance

Alias IP ranges, Accelerators, and min CPU platform are now GA.

* Move common instance code into utils.go

Methods used by both resource_compute_instance and
resource_compute_instance_template are currently spread between their respective
files, and utils.go.

This commit moves them all into utils.go for the sake of consistency. It may be
worth considering an instance_common.go file or similar.

* Unify compute_instance and compute_instance_template network_interface and service_account code

This has the side effect of enabling Alias IP range support for
compute_instance_templates.

* Add tests for compute instance template Alias IP ranges

* Mark instance template region as computed

We compute it from the subnet its network interfaces are in. Note this
is not new behaviour - I believe it was erroneously missing the computed
flag.

* Support guest accelerators for instance templates

Since most of the code is already there.

* Add a test for using 'address' rather than 'network_ip' for instance templates

* Don't mark assigned_nat_ip as deprecated

* Remove network_interface schema fields that don't make sense for a compute instance template

* Add newline after count in instance template docs

* Don't try to dedupe guest accelerator expansion code

The API calls to Google to create guest accelerators take different values
for instances and instance templates. Instance templates don't have a zone
and can thus *only* be passed a guest accelerator name.

* Use ParseNetworkFieldValue instead of getNetworkLink

* Add support for parsing regional fields, and subnetworks specifically

Currently unused because subnetworks may have a separate project from that
of the instance using them, which complicates looking up the project field.

* Fall back to provider region when parsing regional field values

Also slightly refactors getXFromSchema field helper functions for readability.

* Revert to assigned_nat_ip in compute instance docs

* Add beta scaffolding to compute instance and compute instance template

Note these resources don't currently use beta features - this is futureproofing.

* Fix indentation in comment about instance template alias IP ranges

* Consolidate metadata helper functions in metadata.go

* Move compute instance (and template) related helpers into their own file

google_compute_instance

Manages a VM instance resource within GCE. For more information see the official documentation and API.

Example Usage

resource "google_compute_instance" "default" {
  name         = "test"
  machine_type = "n1-standard-1"
  zone         = "us-central1-a"

  tags = ["foo", "bar"]

  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-8"
    }
  }

  // Local SSD disk
  scratch_disk {
  }

  network_interface {
    network = "default"

    access_config {
      // Ephemeral IP
    }
  }

  metadata {
    foo = "bar"
  }

  metadata_startup_script = "echo hi > /test.txt"

  service_account {
    scopes = ["userinfo-email", "compute-ro", "storage-ro"]
  }
}

Argument Reference

The following arguments are supported:

  • boot_disk - (Required) The boot disk for the instance. Structure is documented below.

  • machine_type - (Required) The machine type to create. To create a custom machine type, value should be set as specified here

  • name - (Required) A unique name for the resource, required by GCE. Changing this forces a new resource to be created.

  • zone - (Required) The zone that the machine should be created in.

  • network_interface - (Required) Networks to attach to the instance. This can be specified multiple times. Structure is documented below.


  • attached_disk - (Optional) List of disks to attach to the instance. Structure is documented below.

  • can_ip_forward - (Optional) Whether to allow sending and receiving of packets with non-matching source or destination IPs. This defaults to false.

  • create_timeout - (Optional) Configurable timeout in minutes for creating instances. Default is 4 minutes. Changing this forces a new resource to be created.

  • description - (Optional) A brief description of this resource.

  • labels - (Optional) A set of key/value label pairs to assign to the instance.

  • metadata - (Optional) Metadata key/value pairs to make available from within the instance.

  • metadata_startup_script - (Optional) An alternative to using the startup-script metadata key, except this one forces the instance to be recreated (thus re-running the script) if it is changed. This replaces the startup-script metadata key on the created instance and thus the two mechanisms are not allowed to be used simultaneously.

  • project - (Optional) The project in which the resource belongs. If it is not provided, the provider project is used.

  • scheduling - (Optional) The scheduling strategy to use. More details about this configuration option are detailed below.

  • scratch_disk - (Optional) Scratch disks to attach to the instance. This can be specified multiple times for multiple scratch disks. Structure is documented below.

  • service_account - (Optional) Service account to attach to the instance. Structure is documented below.

  • tags - (Optional) A list of tags to attach to the instance.


The boot_disk block supports:

  • auto_delete - (Optional) Whether the disk will be auto-deleted when the instance is deleted. Defaults to true.

  • device_name - (Optional) Name with which attached disk will be accessible under /dev/disk/by-id/

  • disk_encryption_key_raw - (Optional) A 256-bit [customer-supplied encryption key] (https://cloud.google.com/compute/docs/disks/customer-supplied-encryption), encoded in RFC 4648 base64 to encrypt this disk.

  • initialize_params - (Optional) Parameters for a new disk that will be created alongside the new instance. Either initialize_params or source must be set. Structure is documented below.

  • source - (Optional) The name or self_link of the existing disk (such as those managed by google_compute_disk) to attach.

The initialize_params block supports:

  • size - (Optional) The size of the image in gigabytes. If not specified, it will inherit the size of its base image.

  • type - (Optional) The GCE disk type. May be set to pd-standard or pd-ssd.

  • image - (Optional) The image from which to initialize this disk. This can be one of: the image's self_link, projects/{project}/global/images/{image}, projects/{project}/global/images/family/{family}, global/images/{image}, global/images/family/{family}, family/{family}, {project}/{family}, {project}/{image}, {family}, or {image}.

The scratch_disk block supports:

  • interface - (Optional) The disk interface to use for attaching this disk; either SCSI or NVME. Defaults to SCSI.

The attached_disk block supports:

The network_interface block supports:

  • network - (Optional) The name or self_link of the network to attach this interface to. Either network or subnetwork must be provided.

  • subnetwork - (Optional) The name or self_link of the subnetwork to attach this interface to. The subnetwork must exist in the same region this instance will be created in. Either network or subnetwork must be provided.

  • subnetwork_project - (Optional) The project in which the subnetwork belongs. If the subnetwork is a self_link, this field is ignored in favor of the project defined in the subnetwork self_link. If the subnetwork is a name and this field is not provided, the provider project is used.

  • address - (Optional) The private IP address to assign to the instance. If empty, the address will be automatically assigned.

  • access_config - (Optional) Access configurations, i.e. IPs via which this instance can be accessed via the Internet. Omit to ensure that the instance is not accessible from the Internet (this means that ssh provisioners will not work unless you are running Terraform can send traffic to the instance's network (e.g. via tunnel or because it is running on another cloud instance on that network). This block can be repeated multiple times. Structure documented below.

  • alias_ip_range - (Optional) An array of alias IP ranges for this network interface. Can only be specified for network interfaces on subnet-mode networks. Structure documented below.

The access_config block supports:

  • nat_ip - (Optional) The IP address that will be 1:1 mapped to the instance's network ip. If not given, one will be generated.

The alias_ip_range block supports:

  • ip_cidr_range - The IP CIDR range represented by this alias IP range. This IP CIDR range must belong to the specified subnetwork and cannot contain IP addresses reserved by system or used by other network interfaces. This range may be a single IP address (e.g. 10.2.3.4), a netmask (e.g. /24) or a CIDR format string (e.g. 10.1.2.0/24).

  • guest_accelerator - (Optional) List of the type and count of accelerator cards attached to the instance. Structure documented below.

  • min_cpu_platform - (Optional) Specifies a minimum CPU platform for the VM instance. Applicable values are the friendly names of CPU platforms, such as Intel Haswell or Intel Skylake. See the complete list here.

The guest_accelerator block supports:

  • type (Required) - The accelerator type resource to expose to this instance. E.g. nvidia-tesla-k80.

  • count (Required) - The number of the guest accelerator cards exposed to this instance.
