Creating a Security Group

Function

This API is used to create a security group.

URI

POST /v1/{project_id}/security-groups

Table 1 describes the parameters.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain a project ID, see Obtaining a Project ID.

Request Parameters

**Table 2** Request parameter
Parameter	Mandatory	Type	Description
security_group	Yes	security_group object	Specifies the security group objects. For details, see Table 3.

**Table 3** Description of **security_group** fields
Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the security group name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
vpc_id	No	String	Specifies the ID of the VPC that the security group is associated with. NOTE: Currently, this parameter is not recommended because it is only used as a prompt and does not restrict that the security group must be associated with the VPC.
enterprise_project_id	No	String	Specifies the enterprise project ID. When creating a security group, associate the enterprise project ID with the security group. The value is 0 or a string that contains a maximum of 36 characters in UUID format with hyphens (-). Value 0 indicates the default enterprise project. NOTE: For more information about enterprise projects and how to obtain enterprise project IDs, see the Enterprise Management User Guide.

Example Request

Create a security group named sg-01 in the VPC with ID of 3ec3b33f-ac1c-4630-ad1c-7dba1ed79d85.

Response Parameters

**Table 4** Response parameter
Parameter	Type	Description
security_group	security_group object	Specifies the security group objects. For details, see Table 5.

**Table 5** Description of **security_group** fields
Parameter	Type	Description
name	String	Specifies the security group name.
description	String	Provides supplementary information about the security group.
id	String	Specifies the security group ID, which uniquely identifies the security group.
vpc_id	String	Specifies the ID of the VPC that the security group is associated with. NOTE: Currently, this parameter is not recommended because it is only used as a prompt and does not restrict that the security group must be associated with the VPC.
security_group_rules	Array of security_group_rule objects	Specifies the default security group rules, which ensure that resources in the security group can communicate with one another.
enterprise_project_id	String	Specifies the enterprise project ID. When creating a security group, associate the enterprise project ID with the security group. The value is 0 or a string that contains a maximum of 36 characters in UUID format with hyphens (-). Value 0 indicates the default enterprise project. NOTE: For more information about enterprise projects and how to obtain enterprise project IDs, see the Enterprise Management User Guide.

**Table 6** **security_group_rule** objects
Parameter	Type	Description
id	String	Specifies the security group rule ID, which uniquely identifies the security group rule.
description	String	Provides supplementary information about the security group rule. The value can contain no more than 255 characters, including letters and digits.
security_group_id	String	Specifies the security group rule ID, which uniquely identifies the security group rule.
direction	String	Specifies the direction of access control. Possible values are as follows: egress ingress
ethertype	String	Specifies the IP protocol version. The value can be IPv4 or IPv6.
protocol	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	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	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	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 and remote_address_group_id.
remote_group_id	String	Specifies the ID of the peer security group. The value is mutually exclusive with parameter remote_ip_prefix and remote_address_group_id.
remote_address_group_id	String	Specifies the remote IP address group ID. The value is mutually exclusive with parameters remote_ip_prefix and remote_group_id.
tenant_id	String	Specifies the ID of the project to which the security group rule belongs.
