使用函数服务的 SDK 可以更加便捷地执行创建函数、上传代码和管理触发器等操作。本文介绍 Go SDK 的使用案例。

前提条件

安装 Go 环境，并添加火山 veFaaS 提供的 Go SDK 依赖。具体信息，请参见SDK 概览。

创建「微服务应用」-通过函数模板部署代码

package main

import (
    "fmt"

    "github.com/volcengine/volcengine-go-sdk/service/vefaas"
    "github.com/volcengine/volcengine-go-sdk/volcengine"
    "github.com/volcengine/volcengine-go-sdk/volcengine/credentials"
    "github.com/volcengine/volcengine-go-sdk/volcengine/session"
)

func main() {
    CreateFunctionMicroServiceCode()
}

func CreateFunctionMicroServiceCode() {
    region := "cn-beijing"
    accessKey := "yourAccessKeyId"
    secretKey := "yourAccessKeySecret"

    config := volcengine.NewConfig().WithCredentials(credentials.NewStaticCredentials(accessKey, secretKey, "")).WithRegion(region)

    s, err := session.NewSession(config)
    if err != nil {
       panic(err)
    }

    client := vefaas.New(s)

    resp, err := client.CreateFunction(&vefaas.CreateFunctionInput{
       Name:    volcengine.String("micro-service-doctest"),
       Runtime: volcengine.String("native/v1"),
       VpcConfig: &vefaas.VpcConfigForCreateFunctionInput{
          EnableVpc:        volcengine.Bool(true),
          VpcId:            volcengine.String("vpc-id"),
          SubnetIds:        []*string{volcengine.String("subnet-id")},
          SecurityGroupIds: []*string{volcengine.String("sg-id")},
       },
       CpuStrategy: volcengine.String("always"),
       Command:     volcengine.String("./run.sh"),
    })

    if err != nil {
       panic(err)
    }

    fmt.Println(resp)

}

请根据业务真实情况配置代码参数，可参考文档CreateFunction，下表只介绍创建微服务应用时的特殊配置。

创建「微服务应用」-通过镜像部署代码

package main

import (
    "fmt"

    "github.com/volcengine/volcengine-go-sdk/service/vefaas"
    "github.com/volcengine/volcengine-go-sdk/volcengine"
    "github.com/volcengine/volcengine-go-sdk/volcengine/credentials"
    "github.com/volcengine/volcengine-go-sdk/volcengine/session"
)

const (
    region    = "cn-beijing"
    accessKey = "yourAccessKeyId"
    secretKey = "yourAccessKeySecret"
)

func main() {
    CreateFunctionMicroServiceImage()
}


func CreateFunctionMicroServiceImage() {
    config := volcengine.NewConfig().WithCredentials(credentials.NewStaticCredentials(accessKey, secretKey, "")).WithRegion(region)

    s, err := session.NewSession(config)
    if err != nil {
        panic(err)
    }

    client := vefaas.New(s)

    resp, err := client.CreateFunction(&vefaas.CreateFunctionInput{
        Name:       volcengine.String("micro-service-image-doctest"),
        Runtime:    volcengine.String("native/v1"),
        SourceType: volcengine.String("image"),
        Source:     volcengine.String("vefaas-enterprise-ap-southeast-1.cr.volces.com/vefaastest/nodejs:1.0"),
        VpcConfig: &vefaas.VpcConfigForCreateFunctionInput{
            EnableVpc:        volcengine.Bool(true),
            VpcId:            volcengine.String("vpc-id"),
            SubnetIds:        []*string{volcengine.String("subnet-id")},
            SecurityGroupIds: []*string{volcengine.String("sg-id")},
        },
        CpuStrategy: volcengine.String("always"),
        Command:     volcengine.String("/opt/application/run.sh"),
    })

    if err != nil {
        panic(err)
    }

    fmt.Println(resp)

}

请根据业务真实情况配置代码参数，可参考文档CreateFunction，下表只介绍创建微服务应用时的特殊配置。

结果验证

通过 SDK 创建函数后，您可以登录函数服务控制台查看是否成功创建函数，微服务应用的CPU 分配模式固定为始终分配。
