我不熟悉 Golang AWS SDK，但如果是我，我在 SDK 文檔中找不到它，我會查找 AWS CLI 文檔并在那里找到命令，因為它們可能會轉(zhuǎn)換為 SDK 或最壞情況下的運行系統(tǒng)Golang 中的命令來執(zhí)行 CLI 并獲得相同的結(jié)果。

GetResources

https://docs.aws.amazon.com/cli/latest/reference/resourcegroupstaggingapi/get-resources.html

返回與位于 AWS 賬戶的指定區(qū)域中的指定標(biāo)簽（鍵和值）關(guān)聯(lián)的所有標(biāo)記資源。

因此，您可以使用它來獲取具有特定標(biāo)簽的所有資源，然后在 Golang 中迭代結(jié)果以僅選擇 ELB

看起來您可以在一個命令中按標(biāo)簽和資源進行過濾：

看起來 golang sdk 確實存在該命令

https://docs.aws.amazon.com/sdk-for-go/api/service/resourcegroupstaggingapi/#ResourceGroupsTaggingAPI.GetResources

我認為我上面強調(diào)的選項可供您使用。

在 Golang 中執(zhí)行

您將使用諸如 exec 之類的東西。 https://golang.org/pkg/os/exec/

本教程可能包含如何從 exec https://nathanleclaire.com/blog/2014/12/29/shelled-out-commands-in-golang/獲取結(jié)果

示例代碼

package main

import (

    "fmt"

    "strings"

    "github.com/aws/aws-sdk-go/aws"

    "github.com/aws/aws-sdk-go/aws/credentials"

    "github.com/aws/aws-sdk-go/aws/session"

    "github.com/aws/aws-sdk-go/service/elb"

    "github.com/aws/aws-sdk-go/service/resourcegroupstaggingapi"

)

const (

    // ProviderName is the cloud provider providing loadbalancing functionality

    ProviderName = "aws"

)

// ELB is the struct implementing the lbprovider interface

type ELB struct {

    client            *elb.ELB

    elbResourceName   string

    resourceapiClient *resourcegroupstaggingapi.ResourceGroupsTaggingAPI

}

// NewELB is the factory method for ELB

func NewELB(id string, secret string, region string) (*ELB, error) {

    awsConfig := &aws.Config{

        Region:      aws.String(region),

        Credentials: credentials.NewStaticCredentials(id, secret, ""),

    }

    awsConfig = awsConfig.WithCredentialsChainVerboseErrors(true)

    sess, err := session.NewSession(awsConfig)

    if err != nil {

        return nil, fmt.Errorf("Unable to initialize AWS session: %v", err)

    }

    return &ELB{

        client:            elb.New(sess),

        resourceapiClient: resourcegroupstaggingapi.New(sess),

        elbResourceName:   "elasticloadbalancing",

    }, nil

}

// GetLoadbalancersByTag gets the loadbalancers by tag

func (e *ELB) GetLoadbalancersByTag(tagKey string, tagValue string) ([]string, error) {

    tagFilters := &resourcegroupstaggingapi.TagFilter{}

    tagFilters.Key = aws.String(tagKey)

    tagFilters.Values = append(tagFilters.Values, aws.String(tagValue))

    getResourcesInput := &resourcegroupstaggingapi.GetResourcesInput{}

    getResourcesInput.TagFilters = append(getResourcesInput.TagFilters, tagFilters)

    getResourcesInput.ResourceTypeFilters = append(

        getResourcesInput.ResourceTypeFilters,

        aws.String(e.elbResourceName),

    )

    resources, err := e.resourceapiClient.GetResources(getResourcesInput)

    if err != nil {

        return nil, err

    }

    elbs := []string{}

    for _, resource := range resources.ResourceTagMappingList {

        elbs = append(elbs, strings.Split(*resource.ResourceARN, "/")[1])

    }

    return elbs, nil

}

您可以簡單地遍歷 ELB 列表并按標(biāo)簽過濾。

    svc := elbv2.New(...)

    input := &elbv2.DescribeLoadBalancersInput{

            LoadBalancerArns: []*string{},

    }

    result, _ := svc.DescribeLoadBalancers(input)

    var list_of_arns []*string

    for _, lb := range result.LoadBalancers{

            list_of_arns = append(list_of_arns, lb.LoadBalancerArn)

    }

    input2 := &elbv2.DescribeTagsInput{

            ResourceArns: list_of_arns,

    }

    result2, _ := svc.DescribeTags(input2)

    fmt.Println(result2.TagDescriptions)
