Method: instanceGroupManagers.listPerInstanceConfigs

Lists all of the per-instance configurations defined for the managed instance group. The orderBy query parameter is not supported.

HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/instanceGroupManagers/{instanceGroupManager}/listPerInstanceConfigs

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
zone

string

The name of the zone where the managed instance group is located. It should conform to RFC1035.
instanceGroupManager

string

The name of the managed instance group. It should conform to RFC1035.

Authorization requires the following IAM permission on the specified resource instanceGroupManager:

  • compute.instanceGroupManagers.get

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

Fields
items[]

object

[Output Only] The list of PerInstanceConfig.
items[].name

string

The name of a per-instance configuration and its corresponding instance. Serves as a merge key during instanceGroupManagers.updatePerInstanceConfigs operations, that is, if a per-instance configuration with the same name exists then it will be updated, otherwise a new one will be created for the VM instance with the same name. An attempt to create a per-instance configconfiguration for a VM instance that either doesn't exist or is not part of the group will result in an error.
items[].preservedState

object

The intended preserved state for the given instance. Does not contain preserved state generated from a stateful policy.
items[].preservedState.disks[]

map (key: string, value: object)

Preserved disks defined for this instance. This map is keyed with the device names of the disks.
items[].preservedState.disks[].source

string

The URL of the disk resource that is stateful and should be attached to the VM instance.
items[].preservedState.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[].preservedState.disks[].autoDelete

enum

These stateful disks will never be deleted during autohealing, update, instance recreate operations. This flag is used to configure if the disk should be deleted after it is no longer used by the group, e.g. when the given instance or the whole MIG is deleted. Note: disks attached in READ_ONLY mode cannot be auto-deleted.
items[].preservedState.metadata

map (key: string, value: string)

Preserved metadata defined for this instance.
items[].preservedState.internalIPs[]

map (key: string, value: object)

Preserved internal IPs defined for this instance. This map is keyed with the name of the network interface.
items[].preservedState.internalIPs[].autoDelete

enum

These stateful IPs will never be released during autohealing, update or VM instance recreate operations. This flag is used to configure if the IP reservation should be deleted after it is no longer used by the group, e.g. when the given instance or the whole group is deleted.
items[].preservedState.internalIPs[].ipAddress

object

Ip address representation
items[].preservedState.internalIPs[].ipAddress.literal

string

An IPv4 internal network address to assign to the instance for this network interface.
items[].preservedState.internalIPs[].ipAddress.address

string

The URL of the reservation for this IP address.
items[].preservedState.externalIPs[]

map (key: string, value: object)

Preserved external IPs defined for this instance. This map is keyed with the name of the network interface.
items[].preservedState.externalIPs[].autoDelete

enum

These stateful IPs will never be released during autohealing, update or VM instance recreate operations. This flag is used to configure if the IP reservation should be deleted after it is no longer used by the group, e.g. when the given instance or the whole group is deleted.
items[].preservedState.externalIPs[].ipAddress

object

Ip address representation
items[].preservedState.externalIPs[].ipAddress.literal

string

An IPv4 internal network address to assign to the instance for this network interface.
items[].preservedState.externalIPs[].ipAddress.address

string

The URL of the reservation for this IP address.
items[].status

enum

The status of applying this per-instance configuration on the corresponding managed instance.
items[].fingerprint

string (bytes format)

Fingerprint of this per-instance config. This field can be used in optimistic locking. It is ignored when inserting a per-instance config. An up-to-date fingerprint must be provided in order to update an existing per-instance configuration or the field needs to be unset.

A base64-encoded string.
nextPageToken

string

[Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.
warning

object

[Output Only] Informational warning message.
warning.code

enum

[Output Only] A warning code, if applicable. For example, Compute Engine returns NO_RESULTS_ON_PAGE if there are no results in the response.
warning.message

string

[Output Only] A human-readable description of the warning code.
warning.data[]

object

[Output Only] Metadata about this warning in key: value format. For example: 

"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).
warning.data[].value

string

[Output Only] A warning data value corresponding to the key.
