Creating a Security Group Rule

Function

This API is used to create a security group rule.

URI

POST /v1/{project_id}/security-group-rules

Request Parameters

Table 1 Request parameter

Parameter	Mandatory	Type	Description
security_group_rule	Yes	security_group_rule object	Specifies the security group rule objects. For details, see Table 2.

Table 2 Description of the security_group_rule field

Parameter	Mandatory	Type	Description
security_group_id	Yes	String	Specifies the security group ID.
description	No	String	Provides supplementary information about the security group rule. The value can contain no more than 255 characters, including letters and digits.
direction	Yes	String	Access control direction specified in a security group rule. The value can be: egress ingress
ethertype	No	String	Specifies the IP protocol version. The value can be IPv4 or IPv6. If you do not set this parameter, IPv4 is used by default.
protocol	No	String	Specifies the protocol type. The value can be icmp, tcp, udp, or an IP protocol number (0 to 255, for example, 47 for GRE) If the parameter is left blank, all protocols are supported.
port_range_min	No	Integer	Specifies the start port number. The value ranges from 1 to 65535. The value cannot be greater than the port_range_max value. An empty value indicates all ports. If the protocol is icmp, the value range is shown in ICMP-Port Range Relationship Table.
port_range_max	No	Integer	Specifies the end port number. The value ranges from 1 to 65535. If the protocol is not icmp, the value cannot be smaller than the port_range_min value. An empty value indicates all ports. If the protocol is icmp, the value range is shown in ICMP-Port Range Relationship Table.
remote_ip_prefix	No	String	Specifies the remote IP address. If the access control direction is set to egress, the parameter specifies the source IP address. If the access control direction is set to ingress, the parameter specifies the destination IP address. The value can be in the CIDR format or IP addresses. The parameter is mutually exclusive with parameter remote_group_id.
remote_group_id	No	String	Specifies the ID of the peer security group. The value is mutually exclusive with parameter remote_ip_prefix.
remote_address_group_id	No	String	Specifies the remote IP address group ID. You can log in to the management console and view the ID on the IP address group page. The value is mutually exclusive with parameters remote_ip_prefix and remote_group_id.

Example Request

• Create an inbound rule in the security group whose ID is a7734e61-b545-452d-a3cd-0189cbd9747a.
