Creating a VPC Endpoint Service¶
Scenarios¶
There are two types of VPC endpoint services: gateway and interface.
Gateway VPC endpoint services are created only for cloud services.
Interface VPC endpoint services can be created for both cloud services and your private services. Cloud services are configured as VPC endpoint services by the O&M personnel by default. However, you need to create VPC endpoint services for your private services.
This section describes how to configure a private service into an interface VPC endpoint service.
Constraints¶
VPC endpoint services are region-level resources. Select a region and project when you create such a service.
Each tenant can create a maximum of 20 VPC endpoint services.
The following private services can be configured into VPC endpoint services:
Elastic load balancer: Backend resources of this type suit services that receive high access traffic and demand high reliability and disaster recovery (DR) performance.
ECS: Backend resources of this type serve as servers.
BMS: Backend resources of this type serve as servers. BMS will be discarded. You are recommended to choose Elastic load balancer.
VIP: Backend resources of this type serve as virtual IP addresses. The VIP type will be discarded. The ELB type is recommended.
One VPC endpoint service can have only one backend resource.
Prerequisites¶
There is a load balancer in the VPC where you are going to create the VPC endpoint service.
Procedure¶
Log in to the management console.
Click
in the upper left corner and select the required region and project.Click Service List and choose Networking > VPC Endpoint.
In the navigation pane on the left, choose VPC Endpoint > VPC Endpoint Services. In the upper right corner, click Create VPC Endpoint Service.
The Create VPC Endpoint Service page is displayed.
Figure 1 Create VPC Endpoint Service¶
Configure parameters by referring to Table 1.
Table 1 Parameters for creating a VPC endpoint service¶ Parameter
Description
Region
Specifies the region where the VPC endpoint service is to be deployed.
Resources in different regions cannot communicate with each other over an intranet. For lower latency and quicker access, select the nearest region.
Name
This parameter is optional.
Specifies the name of the VPC endpoint service.
The name can contain a maximum of 16 characters, including letters, digits, underscores (_), and hyphens (-).
If you do not enter a name, the system generates a name in {region}.{service_id} format, for example, eu-de.69e93219-e3ad-43b9-8416-9d788319ac9f.
If you enter a name, the system generates a name in {region}.{Name}.{service_id} format, for example, eu-de.test.e9c186ca-99e4-4a88-9011-8898f1d680c0.
VPC
Specifies the VPC where the VPC endpoint service is to be deployed.
Service Type
Specifies the type of the VPC endpoint service. The type can only be Interface.
Connection Approval
Specifies whether the connection between a VPC endpoint and a VPC endpoint service requires approval from the owner of the VPC endpoint service.
You can enable or disable Connection Approval.
When Connection Approval is enabled, any VPC endpoint for connecting to the VPC endpoint service needs to be approved. For details, see Managing Connections of a VPC Endpoint Service.
Port Mapping
Specifies the protocol and ports used for communications between the VPC endpoint service and a VPC endpoint. The protocol is TCP.
Service Port: provided by the backend resource bound to the VPC endpoint service.
Terminal Port: provided by the VPC endpoint, allowing you to access the VPC endpoint service.
The service and terminal port numbers range from 1 to 65535. A maximum of 50 port mappings can be added at a time.
Note
Accessing a VPC endpoint service from a VPC endpoint is to access the service port from the associated terminal port.
After a port mapping is added, it cannot be modified or deleted.
Backend Resource Type
Specifies the backend resource that provides services to be accessed.
The following backend resource types are supported:
Elastic load balancer: Backend resources of this type suit services that receive high access traffic and demand high reliability and disaster recovery (DR) performance.
ECS: Backend resources of this type serve as servers.
BMS: Backend resources of this type serve as servers. BMS will be discarded. You are recommended to choose Elastic load balancer.
In this example, select Elastic load balancer.
Note
For the security group associated with the backend resource configured for the VPC endpoint service, add an inbound rule, with Source set to 198.19.128.0/17. For details, see Adding a Security Group Rule in the Virtual Private Cloud User Guide.
Load Balancer
When Backend Resource Type is set to Elastic load balancer, select the load balancer that provides services from the drop-down list.
Note
If an elastic load balancer is used as the backend resource, the source IP address received by the VPC endpoint service is not the real address of the client.
ECS List
When you select ECS for Backend Resource Type, select an ECS from the ECS list.
BMS List
When you select BMS for Backend Resource Type, select a BMS from the BMS list.
Note
The BMS type will be discarded. The ELB type is recommended.
Tag
This parameter is optional.
Specifies the VPC endpoint service tag, which consists of a key and a value. You can add up to 20 tags to each VPC endpoint service.
Tag keys and values must meet requirements listed in Table 2.
Note
If a predefined tag has been created on TMS, you can directly select the corresponding tag key and value.
For details about predefined tags, see Predefined Tag Overview.
Table 2 Tag requirements for VPC endpoint services¶ Parameter
Requirement
Tag key
Cannot be left blank.
Must be unique for each resource.
Can contain a maximum of 36 characters.
Can contain only digits, letters, hyphens (-), underscores (_), and at signs (@).
Tag value
Can contain a maximum of 43 characters.
Can contain only digits, letters, hyphens (-), underscores (_), and at signs (@).
