Method: instances.list

Retrieves the list of instances contained within the specified zone.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instances

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
zone

string

The name of the zone for this request.

Query parameters

Parameters
maxResults

integer (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)
pageToken

string

Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
filter

string

A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <.

For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example, (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true).
orderBy

string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

Currently, only sorting by name or creationTimestamp desc is supported.

Request body

The request body must be empty.

items[].networkInterfaces[].network

string

URL of the network resource for this instance. When creating an instance, if neither the network nor the subnetwork is specified, the default network global/networks/default is used; if the network is not specified but the subnetwork is specified, the network is inferred.

If you specify this property, you can specify the network as a full or partial URL. For example, the following are all valid URLs:

items[].networkInterfaces[].subnetwork

string

The URL of the Subnetwork resource for this instance. If the network resource is in legacy mode, do not specify this field. If the network is in auto subnet mode, specifying the subnetwork is optional. If the network is in custom subnet mode, specifying the subnetwork is required.

This range may be a single IP address (such as 10.2.3.4), a netmask (such as /24) or a CIDR-formatted string (such as 10.1.2.0/24).
items[].networkInterfaces[].aliasIpRanges[].subnetworkRangeName

string

The name of a subnetwork secondary IP range from which to allocate an IP alias range. If not specified, the primary range of the subnetwork is used.
items[].networkInterfaces[].fingerprint

string (bytes format)

items[].disks[].deviceName

string

Specifies a unique device name of your choice that is reflected into the /dev/disk/by-id/google-* 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-disk-x, where x is a number assigned by Google Compute Engine. This field is only applicable for persistent disks.
items[].disks[].index

integer

[Output Only] A zero-based index to this disk, where 0 is reserved for the boot disk. If you have many disks attached to an instance, each disk would have a unique index number.

boolean

Indicates that this is a boot disk. The virtual machine will use the first partition of the disk for its root filesystem.
items[].disks[].initializeParams

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.
items[].disks[].initializeParams.diskName

string

Specifies the disk name. If not specified, the default is to use the name of the instance. If the disk with the instance name exists already in the given zone/region, a new name will be automatically generated.
items[].disks[].initializeParams.sourceImage

string

To create a disk with one of the public operating system images, specify the image by its family name. For example, specify family/debian-9 to use the latest Debian 9 image:

projects/debian-cloud/global/images/family/debian-9

Alternatively, use a specific version of a public operating system image:

projects/debian-cloud/global/images/debian-9-stretch-vYYYYMMDD

To create a disk with a custom image that you created, specify the image name in the following format:

global/images/my-custom-image

You can also specify a custom image by its image family, which returns the latest version of the image in that family. Replace the image name with family/family-name:

global/images/family/my-image-family

If the source image is deleted later, this field will not be set.
items[].disks[].initializeParams.diskSizeGb

string (int64 format)

Specifies the size of the disk in base-2 GB. The size must be at least 10 GB. If you specify a sourceImage, which is required for boot disks, the default size is the size of the sourceImage. If you do not specify a sourceImage, the default disk size is 500 GB.
items[].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:

Note that for InstanceTemplate, this is the name of the disk type, not URL.
items[].disks[].initializeParams.sourceImageEncryptionKey

object

The customer-supplied encryption key of the source image. Required if the source image is protected by a customer-supplied encryption key.

Instance templates do not store customer-supplied encryption keys, so you cannot create disks for instances in a managed instance group if the source images are encrypted with your own keys.
items[].disks[].initializeParams.sourceImageEncryptionKey.rawKey

string

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.
items[].disks[].initializeParams.sourceImageEncryptionKey.rsaEncryptedKey

string

Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource.

The key must meet the following requirements before you can provide it to Compute Engine:

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
items[].disks[].initializeParams.sourceSnapshot

string

The source snapshot to create this disk. When creating a new instance, one of initializeParams.sourceSnapshot or initializeParams.sourceImage or disks.source is required except for local SSD.

To create a disk with a snapshot that you created, specify the snapshot name in the following format:

global/snapshots/my-backup

If the source snapshot is deleted later, this field will not be set.

The ID of a supported feature. Read Enabling guest operating system features to see a list of available options.
items[].disks[].diskEncryptionKey

object

Encrypts or decrypts a disk using a customer-supplied encryption key.

If you are creating a new disk, this field encrypts the new disk using an encryption key that you provide. If you are attaching an existing disk that is already encrypted, this field decrypts the disk using the customer-supplied encryption key.

If you encrypt a disk using a customer-supplied key, you must provide the same key again when you attempt to use this resource at a later time. For example, you must provide the key when you create a snapshot or an image from the disk or when you attach the disk to a virtual machine instance.

If you do not provide an encryption key, then the disk will be encrypted using an automatically generated key and you do not need to provide a key to use the disk later.

Instance templates do not store customer-supplied encryption keys, so you cannot use your own keys to encrypt disks in a managed instance group.
items[].disks[].diskEncryptionKey.rawKey

string

Specifies a 256-bit customer-supplied encryption key, encoded in RFC 4648 base64 to either encrypt or decrypt this resource.

string

Specifies an RFC 4648 base64 encoded, RSA-wrapped 2048-bit customer-supplied encryption key to either encrypt or decrypt this resource.

The key must meet the following requirements before you can provide it to Compute Engine:

  1. The key is wrapped using a RSA public key certificate provided by Google.
  2. After being wrapped, the key must be encoded in RFC 4648 base64 encoding.
