Initialize and manage Alibaba Cloud SDK clients in Go. Covers sync.Once singleton, goroutine safety, endpoint vs region configuration, VPC endpoints, and debug mode. Use when the user creates Go SDK clients, configures endpoints, asks about goroutine safety, singleton patterns, or VPC endpoint setup in the Alibaba Cloud Go SDK.

Client Initialization Best Practices (Go)

Core Rules

  • Client is goroutine-safe — safe to share across goroutines without additional synchronization.
  • Use singleton pattern — do NOT create new client instances per request. Frequent client creation wastes resources.
  • Prefer explicit endpoint over region-based endpoint resolution.

Recommended Client Creation

go
import (
    "os"
    "sync"
 
    openapi "github.com/alibabacloud-go/darabonba-openapi/v2/client"
    ecs "github.com/alibabacloud-go/ecs-20140526/v3/client"
    "github.com/alibabacloud-go/tea/tea"
)
 
var (
    ecsClient     *ecs.Client
    ecsClientOnce sync.Once
)
 
func GetEcsClient() *ecs.Client {
    ecsClientOnce.Do(func() {
        config := &openapi.Config{
            AccessKeyId:     tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID")),
            AccessKeySecret: tea.String(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET")),
            Endpoint:        tea.String("ecs.cn-hangzhou.aliyuncs.com"),
        }
        var err error
        ecsClient, err = ecs.NewClient(config)
        if err != nil {
            panic(err)
        }
    })
    return ecsClient
}

Endpoint Configuration

Priority: explicit Endpoint > region-based resolution via RegionId.

go
// Preferred: explicit endpoint
config.Endpoint = tea.String("ecs.cn-hangzhou.aliyuncs.com")
 
// Alternative: SDK resolves endpoint from region
config.RegionId = tea.String("cn-hangzhou")
VPC Endpoints

Use VPC endpoints when running inside Alibaba Cloud VPC:

go
config.Endpoint = tea.String("ecs-vpc.cn-hangzhou.aliyuncs.com")
File Upload APIs (Advance)

Set both RegionId and Endpoint to the same region for file upload APIs:

go
config.RegionId = tea.String("cn-shanghai")
config.Endpoint = tea.String("objectdet.cn-shanghai.aliyuncs.com")
// VPC file upload authorization:
client.OpenPlatformEndpoint = tea.String("openplatform-vpc.cn-shanghai.aliyuncs.com")
client.EndpointType = tea.String("internal")

SDK Components

ComponentDescription
Core SDK (darabonba-openapi)Generic calls, no product dependency
Product SDK (e.g., ecs-20140526)Typed client, models, convenience methods

Debugging

Enable debug mode via environment variable to log all requests:

bash
export DEBUG=tea
