string

Project ID for this request.

string

The name of thezone where the instance group is located.

string

The name of the instance group from which you want to generate a list of included instances.

Authorization requires the followingIAM permission on the specified resourceinstanceGroup:

• compute.instanceGroups.get

integer (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger thanmaxResults, Compute Engine returns anextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are0 to500, inclusive. (Default:500)

string

Specifies a page token to use. SetpageToken to thenextPageToken returned by a previous list request to get the next page of results.

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 proposalAIP-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 namedexample-instance by specifyingname != example-instance.

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

labels.owner:*

You can also filter nested fields. For example, you could specifyscheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based onresource 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 anAND expression. However, you can includeAND andOR expressions explicitly. For example:

(cpuPlatform = "Intel Skylake") OR(cpuPlatform = "Intel Broadwell") AND(scheduling.automaticRestart = true)

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

fieldname eq unquoted literalfieldname 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 GoogleRE2 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 usename ne .*instance.

You cannot combine constraints on multiple fields using regular expressions.

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 usingorderBy="creationTimestamp desc". This sorts results based on thecreationTimestamp 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 byname orcreationTimestamp desc is supported.

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.
