我在 ec2 机器上的 docker 中设置了一个 go 服务器，该服务器使用 aws-sdk-go 模块来调用 AWS api。从以下代码构建的此二进制文件在容器内运行时会出现证书问题。

相同的二进制文件运行良好，并在主机上运行时给出了预期的结果。

package main

import (
    "fmt"

    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/awserr"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/autoscaling"
)

func main() {
    svc := autoscaling.New(session.New(), aws.NewConfig().WithRegion("us-east-1"))
    input := &autoscaling.DescribeAutoScalingGroupsInput{
        AutoScalingGroupNames: []*string{
            aws.String("spark-worker-asg"),
        },
    }

    result, err := svc.DescribeAutoScalingGroups(input)
    if err != nil {
        if aerr, ok := err.(awserr.Error); ok {
            switch aerr.Code() {
            case autoscaling.ErrCodeInvalidNextToken:
                fmt.Println(autoscaling.ErrCodeInvalidNextToken, aerr.Error())
            case autoscaling.ErrCodeResourceContentionFault:
                fmt.Println(autoscaling.ErrCodeResourceContentionFault, aerr.Error())
            default:
                fmt.Println(aerr.Error())
            }
        } else {
            // Print the error, cast err to awserr.Error to get the Code and
            // Message from an error.
            fmt.Println(err.Error())
        }
        return
    }

    fmt.Println(result)
}

您不需要将 IAM 角色分配给 docker 容器，它已经使用 Host IAM tole 作为 Docker 容器可以访问的主机元数据。

上面的错误不是由于权限引起的，它是您的 Docker 镜像中缺少的东西。

尝试添加 ca-certificates在 docker 容器中。

Make sure the ca-certificates package is installed on your instance. After installing restart your Go programs.
