Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.

project

string

Project ID 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.
`returnPartialSuccess`	`boolean` Opt-in for partial success behavior which provides partial results in case of failure. The default value is false and the logic is the same as today.

Request body

The request body must be empty.

`items[].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.
`items[].description`	`string` An optional description of this resource. Provide this property when you create the resource.
`items[].properties`	`object` The instance properties for this instance template.
`items[].properties.description`	`string` An optional text description for the instances that are created from these properties.
`items[].properties.tags`	`object` A list of tags to apply to the instances that are created from these properties. The tags identify valid sources or targets for network firewalls. The setTags method can modify this list of tags. Each tag within the list must comply with RFC1035.
`items[].properties.tags.items[]`	`string` An array of tags. Each tag must be 1-63 characters long, and comply with RFC1035.
`items[].properties.tags.fingerprint`	`string (bytes format)` Specifies a fingerprint for this request, which is essentially a hash of the tags' contents and used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update tags. You must always provide an up-to-date fingerprint hash in order to update or change tags. To see the latest fingerprint, make `get()` request to the instance. A base64-encoded string.
`items[].properties.machineType`	`string` The machine type to use for instances that are created from these properties.
`items[].properties.canIpForward`	`boolean` Enables instances created based on these properties to send packets with source IP addresses other than their own and receive packets with destination IP addresses other than their own. If these instances will be used as an IP gateway or it will be set as the next-hop in a Route resource, specify `true`. If unsure, leave this set to `false`. See the Enable IP forwarding documentation for more information.
`items[].properties.networkInterfaces[]`	`object` An array of network access configurations for this interface.
`items[].properties.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: `https://www.googleapis.com/compute/v1/projects/project/global/networks/network` `projects/project/global/networks/network` `global/networks/default`
`items[].properties.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. If you specify this field, you can specify the subnetwork as a full or partial URL. For example, the following are all valid URLs: `https://www.googleapis.com/compute/v1/projects/project/regions/region/subnetworks/subnetwork` `regions/region/subnetworks/subnetwork`
`items[].properties.networkInterfaces[].networkIP`	`string` An IPv4 internal IP address to assign to the instance for this network interface. If not specified by the user, an unused internal IP is assigned by the system.
`items[].properties.networkInterfaces[].ipv6Address`	`string` [Output Only] An IPv6 internal network address for this network interface.
`items[].properties.networkInterfaces[].name`	`string` [Output Only] The name of the network interface, which is generated by the server. For network devices, these are `eth0`, `eth1`, etc.
`items[].properties.networkInterfaces[].accessConfigs[]`	`object` An array of configurations for this interface. Currently, only one access config, `ONE_TO_ONE_NAT`, is supported. If there are no `accessConfigs` specified, then this instance will have no external internet access.
`items[].properties.networkInterfaces[].accessConfigs[].type`	`enum` The type of configuration. The default and only option is `ONE_TO_ONE_NAT`.
`items[].properties.networkInterfaces[].accessConfigs[].name`	`string` The name of this access configuration. The default and recommended name is `External NAT`, but you can use any arbitrary string, such as `My external IP` or `Network Access`.
`items[].properties.networkInterfaces[].accessConfigs[].natIP`	`string` An external IP address associated with this instance. Specify an unused static external IP address available to the project or leave this field undefined to use an IP from a shared ephemeral IP address pool. If you specify a static external IP address, it must live in the same region as the zone of the instance.
`items[].properties.networkInterfaces[].accessConfigs[].setPublicPtr`	`boolean` Specifies whether a public DNS 'PTR' record should be created to map the external IP address of the instance to a DNS domain name.
`items[].properties.networkInterfaces[].accessConfigs[].publicPtrDomainName`	`string` The DNS domain name for the public PTR record. You can set this field only if the `setPublicPtr` field is enabled.
`items[].properties.networkInterfaces[].accessConfigs[].networkTier`	`enum` This signifies the networking tier used for configuring this access configuration and can only take the following values: `PREMIUM`, `STANDARD`. If an AccessConfig is specified without a valid external IP address, an ephemeral IP will be created with this networkTier. If an AccessConfig with a valid external IP address is specified, it must match that of the networkTier associated with the Address resource owning that IP.
`items[].properties.networkInterfaces[].accessConfigs[].kind`	`string` [Output Only] Type of the resource. Always `compute#accessConfig` for access configs.
`items[].properties.networkInterfaces[].aliasIpRanges[]`	`object` An array of alias IP ranges for this network interface. You can only specify this field for network interfaces in VPC networks.
`items[].properties.networkInterfaces[].aliasIpRanges[].ipCidrRange`	`string` The IP alias ranges to allocate for this interface. 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 (such as `10.2.3.4`), a netmask (such as `/24`) or a CIDR-formatted string (such as `10.1.2.0/24`).
`items[].properties.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[].properties.networkInterfaces[].fingerprint`	`string (bytes format)` Fingerprint hash of contents stored in this network interface. This field will be ignored when inserting an `Instance` or adding a `NetworkInterface`. An up-to-date fingerprint must be provided in order to update the `NetworkInterface`, otherwise the request will fail with error `412 conditionNotMet`. A base64-encoded string.
`items[].properties.networkInterfaces[].kind`	`string` [Output Only] Type of the resource. Always `compute#networkInterface` for network interfaces.
`items[].properties.disks[]`	`object` An array of disks that are associated with the instances that are created from these properties.
`items[].properties.disks[].type`	`enum` Specifies the type of the disk, either `SCRATCH` or `PERSISTENT`. If not specified, the default is `PERSISTENT`.
`items[].properties.disks[].mode`	`enum` The mode in which to attach this disk, either `READ_WRITE` or `READ_ONLY`. If not specified, the default is to attach the disk in `READ_WRITE` mode.
`items[].properties.disks[].source`	`string` Specifies a valid partial or full URL to an existing Persistent Disk resource. When creating a new instance, one of `initializeParams.sourceImage` or `initializeParams.sourceSnapshot` or `disks.source` is required except for local SSD. If desired, you can also attach existing non-root persistent disks using this property. This field is only applicable for persistent disks. Note that for InstanceTemplate, specify the disk name, not the URL for the disk.
`items[].properties.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[].properties.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.
`items[].properties.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.
`items[].properties.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[].properties.disks[].initializeParams.diskName`	`string` Specifies the disk name. If not specified, the default is to use the name of the instance. If a disk with the same name already exists in the given region, the existing disk is attached to the new instance and the new disk is not created.
`items[].properties.disks[].initializeParams.sourceImage`	`string` The source image to create this disk. When creating a new instance, one of `initializeParams.sourceImage` or `initializeParams.sourceSnapshot` or `disks.source` is required except for local SSD. 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[].properties.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.
