| Property name | Value | Description | Notes |
|---|---|---|---|
canIpForward |
boolean |
Allows this instance to send and receive packets with non-matching destination or source IPs. This is required if you plan to use this instance to forward routes. For more information, see Enabling IP Forwarding. | |
cpuPlatform |
string |
[Output Only] The CPU platform used by this instance. | |
creationTimestamp |
string |
[Output Only] Creation timestamp in RFC3339 text format. | |
description |
string |
An optional textual description of the resource; provided by the client when the resource is created. | |
disks[] |
list |
Array of disks associated with this instance. Persistent disks must be created before you can assign them. | |
disks[].autoDelete |
boolean |
Specifies whether the disk will be auto-deleted when the instance is deleted (but not when the disk is detached from the instance). | |
disks[].boot |
boolean |
Indicates that this is a boot disk. The virtual machine will use the first partition of the disk for its root filesystem. | |
disks[].deviceName |
string |
Specifies a unique device name of your choice that is reflected into the /dev/ tree of a Linux operating system running within the instance. This name can be used to reference the device for mounting, resizing, and so on, from within the instance. If not specified, the server chooses a default device name to apply to this disk, in the form persistent-disks-x, where x is a number assigned by Google Compute Engine. This field is only applicable for persistent disks. |
|
disks[].index |
integer |
Assigns a zero-based index to this disk, where 0 is reserved for the boot disk. For example, if you have many disks attached to an instance, each disk would have a unique index number. If not specified, the server will choose an appropriate value. | |
disks[].initializeParams |
nested object |
[Input Only] Specifies the parameters for a new disk that will be created alongside the new instance. Use initialization parameters to create boot disks or local SSDs attached to the new instance. This property is mutually exclusive with the source property; you can only define one or the other, but not both. |
|
disks[].initializeParams.diskName |
string |
Specifies the disk name. If not specified, the default is to use the name of the instance. | |
disks[].initializeParams.diskSizeGb |
long |
Specifies the size of the disk in base-2 GB. | |
disks[].initializeParams.diskStorageType |
string |
Storage type of the disk. | |
disks[].initializeParams.diskType |
string |
Specifies the disk type to use to create the instance. If not specified, the default is pd-standard, specified using the full URL. For example: https://www.googleapis.com/compute/v1/projects/project/zones/zone/diskTypes/pd-standard Other values include pd-ssd and local-ssd. If you define this field, you can provide either the full or partial URL. For example, the following are valid values:
|
|
disks[].initializeParams.sourceImage |
string |
A source image used to create the disk. You can provide a private (custom) image, and Compute Engine will use the corresponding image from your project. For example: global/images/my-private-image Or you can provide an image from a publicly-available project. For example, to use a Debian image from the debian-cloud project, make sure to include the project in the URL: projects/debian-cloud/global/images/debian-7-wheezy-vYYYYMMDD where vYYYYMMDD is the image version. The fully-qualified URL will also work in both cases. |
|
disks[].interface |
string |
||
disks[].kind |
string |
[Output Only] Type of the resource. Always compute#attachedDisk for attached disks. |
|
disks[].licenses[] |
list |

|
disks[].source |
string |
Specifies a valid partial or full URL to an existing Persistent Disk resource. This field is only applicable for persistent disks. | |
disks[].type |
string |
Specifies the type of the disk, either SCRATCH or PERSISTENT. If not specified, the default is PERSISTENT. |
|
id |

|
metadata |
nested object |
The metadata key/value pairs assigned to this instance. This includes custom metadata and predefined keys. | |
metadata.fingerprint |
bytes |
Specifies a fingerprint for this request, which is essentially a hash of the metadata's contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update metadata. You must always provide an up-to-date fingerprint hash in order to update or change metadata. | |
metadata.items[] |
list |
Array of key/value pairs. The total size of all keys and values must be less than 512 KB. | |
metadata.items[].key |
string |
Key for the metadata entry. Keys must conform to the following regexp: [a-zA-Z0-9-_]+, and be less than 128 bytes in length. This is reflected as part of a URL in the metadata server. Additionally, to avoid ambiguity, keys must not conflict with any other metadata keys for the project. |
|
metadata.items[].value |
string |
Value for the metadata entry. These are free-form strings, and only have meaning as interpreted by the image running in the instance. The only restriction placed on values is that their size must be less than or equal to 32768 bytes. | |
metadata.kind |
string |
[Output Only] Type of the resource. Always compute#metadata for metadata. |
|
name |
string |
Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash. |
