Field	Description
security_group_id	string ID of the security group to update. To get the security group ID make a SecurityGroupService.List request. The length must be less than or equal to 50. This field is required.
update_mask	google.protobuf.FieldMask Field mask that specifies which attributes of the Address should be updated.
name	string New name for the security group. The name must be unique within the folder. The value must match the regular expression: `\|[a-zA-Z]([-_a-zA-Z0-9]{0,61}[a-zA-Z0-9])?`.
description	string New description of the security group. The length must be less than or equal to 256.
labels	object (map<string, string>) Security group labels as `key:value` pairs. Existing set of labels is completely replaced by the provided set, so if you just want to add or remove a label: Get the current set of labels with a SecurityGroupService.Get request. Add or remove a label in this set. Send the new set in this field. Each map key must match the regular expression: `[a-z][-_./\\@0-9a-z]`. Each map value must match the regular expression: `[-_./\\@0-9a-z]`. The length of each map key must be between 1 and 63. The length of each map value must be less than or equal to 63. The number of elements must be less than or equal to 64.
rule_specs[]	SecurityGroupRuleSpec Updated rule list. All existing rules will be replaced with given list.

SecurityGroupRuleSpec

Field	Description
description	string Description of the security rule. The length must be less than or equal to 256.
labels	object (map<string, string>) Rule labels as `key:value` pairs. Each map key must match the regular expression: `[a-z][-_./\\@0-9a-z]`. Each map value must match the regular expression: `[-_./\\@0-9a-z]`. The length of each map key must be between 1 and 63. The length of each map value must be less than or equal to 63. The number of elements must be less than or equal to 64.
direction	enum Direction The direction of network traffic allowed by this rule. This field is required. `INGRESS`: Allows ingress traffic. `EGRESS`: Allows egress traffic.
ports	PortRange The range of ports that allow traffic to pass through. Null value means any port.
protocol_name	string Protocol name. Includes only one of the fields `protocol_name`, `protocol_number`. Values from IANA protocol numbers. Null value means any protocol.
protocol_number	int64 Protocol number from IANA protocol numbers. Includes only one of the fields `protocol_name`, `protocol_number`. Values from IANA protocol numbers. Null value means any protocol.
cidr_blocks	CidrBlocks CIDR blocks to allow to recieve or send traffic. Includes only one of the fields `cidr_blocks`, `security_group_id`, `predefined_target`. Only one field must be specified.
security_group_id	string ID of the security group to add rule to. Includes only one of the fields `cidr_blocks`, `security_group_id`, `predefined_target`. Only one field must be specified.
predefined_target	string Predefined target. See security groups rules for more information. Includes only one of the fields `cidr_blocks`, `security_group_id`, `predefined_target`. Only one field must be specified.

PortRange

Field

Description

from_port

int64

The lowest port in the range.
The value must be between 0 and 65535.

to_port

int64

The highest port in the range.
The value must be between 0 and 65535.

CidrBlocks

Field

Description

v4_cidr_blocks[]

string

IPv4 CIDR blocks to allow traffic to.

v6_cidr_blocks[]

string

IPv6 CIDR blocks to allow traffic to.

  "id": "string",
  "description": "string",
  "created_at": "google.protobuf.Timestamp",
  "created_by": "string",
  "modified_at": "google.protobuf.Timestamp",
  "done": "bool",

  // end of the list of possible fields
}

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	google.protobuf.Any Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	google.protobuf.Any The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
