Creating a Dedicated Load Balancer and Binding a New EIP to It¶
Scenarios¶
Call APIs to create a dedicated load balancer and bind a new EIP to it.
Prerequisites¶
You have created a VPC and a subnet.
Procedure¶
Query the subnet you have created.
Send GET https://{vpc_endpoint}/v1/{project_id}/subnets. project_id indicates the project ID.
Add X-Auth-Token to the request header.
Check the response.
The request is successful if the following response is displayed:
{ "subnets": [ { "id": "0535759e-8104-49d9-902c-a05185a94bdf", // Subnet ID "name": "subnet-001", // Subnet name "description": "", "cidr": "172.16.66.0/24", //IPv4 address range "dnsList": [ "100.125.4.6" ], "status": "ACTIVE", "vpc_id": "44789a9f-3e80-451a-ac03-0818f99b6cdd", // VPC ID "ipv6_enable": true, "gateway_ip_v6": "2001:db8:a583:37c::1", "cidr_v6": "2001:db8:a583:37c::/64", "gateway_ip": "172.16.66.1", "dhcp_enable": true, "primary_dns": "100.125.4.6", "availability_zone": "eu-de-01", //AZ of the subnet "neutron_network_id": "0535759e-8104-49d9-902c-a05185a94bdf", // Network ID "neutron_subnet_id": "1492f0ba-cfce-4e2c-86f7-561d757dfeee", // IPv4 subnet ID "neutron_subnet_id_v6": "3c052475-b50b-49b9-abb1-558bad45e592", "extra_dhcp_opts": [ { "opt_value": "8760h", "opt_name": "addresstime" } ] } ] }
If the request is abnormal, locate the fault by referring to HTTP Status Codes for Dedicated Load Balancers.
Create a dedicated load balancer and bind a new EIP to it.
Send POST https://{elb_endpoint}/v3/{project_id}/elb/loadbalancers. project_id indicates the project ID.
Add X-Auth-Token to the request header.
Ensure that the following parameters, including publicip, are passed in the request body:
{ "loadbalancer": { "vpc_id": "e5a892ff-3c33-44ef-ada5-b713eb1f7a8b", "availability_zone_list": [ "br-iaas-odin1a" ], "admin_state_up": true, "vip_subnet_cidr_id": "1800b6b8-a69f-4719-813d-24d62aaf32bd", "name": "elb-ipv4", "publicip": { "network_type": "5_bgp", "bandwidth": { "size": 2, "share_type": "PER", "charge_mode": "bandwidth", "name": "elb_eip_bandwidth" } } } }
Check the response.
The request is successful if the following response is displayed:
