Method: regionInstantSnapshots.list

Retrieves the list of InstantSnapshot resources contained within the specified region.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/instantSnapshots

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
region

string

The name of the region 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. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request.

If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The 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.

The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use:

labels.owner:*

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)

If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples:

fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal")

The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field.

For example, to filter for instances that do not end with name "instance", you would use name ne .*instance.

You cannot combine constraints on multiple fields using regular expressions.
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.

For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code.

Request body

The request body must be empty.

Response body

Contains a list of InstantSnapshot resources.

If successful, the response body contains data with the following structure:

Fields
kind

string

Type of resource.
id

string

[Output Only] Unique identifier for the resource; defined by the server.
items[]

object

A list of InstantSnapshot resources.
items[].kind

string

[Output Only] Type of the resource. Always compute#instantSnapshot for InstantSnapshot resources.
items[].id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.
items[].creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.
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[].status

enum

[Output Only] The status of the instantSnapshot. This can be CREATING, DELETING, FAILED, or READY.
items[].sourceDisk

string

URL of the source disk used to create this instant snapshot. Note that the source disk must be in the same zone/region as the instant snapshot to be created. This can be a full or valid partial URL. For example, the following are valid values:

items[].sourceDiskId

string

[Output Only] The ID value of the disk used to create this InstantSnapshot. This value may be used to determine whether the InstantSnapshot was taken from the current or a previous instance of a given disk name.
items[].diskSizeGb

string (int64 format)

[Output Only] Size of the source disk, specified in GB.
items[].selfLink

string

[Output Only] Server-defined URL for the resource.
items[].selfLinkWithId

string

[Output Only] Server-defined URL for this resource's resource id.
items[].labels

map (key: string, value: string)

Labels to apply to this InstantSnapshot. These can be later modified by the setLabels method. Label values may be empty.
items[].labelFingerprint

string (bytes format)

A fingerprint for the labels being applied to this InstantSnapshot, which is essentially a hash of the labels set used for optimistic locking. The fingerprint is initially generated by Compute Engine and changes after every request to modify or update labels. You must always provide an up-to-date fingerprint hash in order to update or change labels, otherwise the request will fail with error 412 conditionNotMet.

To see the latest fingerprint, make a get() request to retrieve a InstantSnapshot.

A base64-encoded string.
items[].zone

string

[Output Only] URL of the zone where the instant snapshot resides. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
items[].region

"data": [  {  "key": "scope",  "value": "zones/us-east1-d"  }
warning.data[].key

string

[Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
