156<div class="method">
157    <code class="details" id="abandonInstances">abandonInstances(project, region, instanceGroupManager, body, requestId=None)</code>
158  <pre>Flags the specified instances to be immediately removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method.
159
160If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.
161
162You can specify a maximum of 1000 instances with this method per request.
163
164Args:
165  project: string, Project ID for this request. (required)
166  region: string, Name of the region scoping this request. (required)
167  instanceGroupManager: string, Name of the managed instance group. (required)
168  body: object, The request body. (required)
169    The object takes the form of:
170
171{
172    "instances": [ # The URLs of one or more instances to abandon. This can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
173      "A String",
174    ],
175  }
176
177  requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.
178
179For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.
180
181The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

1028  requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.
1029
1030For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

1095    <code class="details" id="list">list(project, region, orderBy=None, maxResults=None, pageToken=None, filter=None)</code>
1096  <pre>Retrieves the list of managed instance groups that are contained within the specified region.
1097
1098Args:
1099  project: string, Project ID for this request. (required)
1100  region: string, Name of the region scoping this request. (required)
1101  orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.
1102
1103You 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.
1104
1105Currently, only sorting by name or creationTimestamp desc is supported.
1106  maxResults: integer, 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)
1107  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.
1108  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 <.
1109
1110For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.
1111
1112You 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.
1113
1114To 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).
1115
1116Returns:
1117  An object of the form:
1118

1120    "nextPageToken": "A 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.

1298  <pre>Lists all errors thrown by actions on instances for a given regional managed instance group.
1299
1300Args:
1301  project: string, Project ID for this request. (required)
1302  region: string, Name of the region scoping this request. This should conform to RFC1035. (required)
1303  instanceGroupManager: string, The name of the managed instance group. It must be a string that meets the requirements in RFC1035, or an unsigned long integer: must match regexp pattern: (?:[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?)|[1-9][0-9]{0,19}. (required)
1304  orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.
1305
1306You 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.
1307
1308Currently, only sorting by name or creationTimestamp desc is supported.
1309  maxResults: integer, 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)
1310  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.
1311  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 <.
1312
1313For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.
1314
1315You 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.
1316
1317To 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).

1492  orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.
1493
1494You 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.
1495
1496Currently, only sorting by name or creationTimestamp desc is supported.
1497  maxResults: integer, 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)
1498  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.
1499  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 <.
1500
1501For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.
1502
1503You 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.
1504
1505To 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).
1506

2027  <pre>Changes the intended size of the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes one or more instances.
2028
2029The resize operation is marked DONE if the resize request is successful. The underlying actions take additional time. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method.
2030
2031If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.

2038  requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.
2039
2040For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.
2041
2042The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

2299
2300  requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.
2301
2302For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.
2303
2304The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).
