Question

我可以使用我的代码访问AWS上的DynamoDB。我可以使用CLI访问本地DynamoDB。但是我不能让两个人互相交谈。

# deploying dynamodb
docker run \
    --detach \
    --tty \
    --interactive \
    --publish 8000:8000 \
    --name lokal_dynamodb amazon/dynamodb-local

# deploying Go with SAM
sam local start-api \
    --template sam/template.yaml \
    --region eu-central-1 \
    --profile default

创建会话

sess, err := session.NewSessionWithOptions(session.Options{
    // Provide SDK Config options, such as Region.
    Config: aws.Config{
        Endpoint: aws.String("http://localhost:8000/"),
        Region:   aws.String("eu-central-1"),
    },
})
if err != nil {
    logger.Println(err)
    return nil
}

返回错误

由于某种原因，SAM Lambda无法连接到localhost DynamoDB，因此您需要创建一个环回IP地址，以供其访问。

ifconfig lo0 alias 172.16.123.1

然后将会话配置更新为：

sess, err := session.NewSessionWithOptions(session.Options{
    // Provide SDK Config options, such as Region.
    Config: aws.Config{
        Endpoint: aws.String("http://172.16.123.1:8000/"),
        Region:   aws.String("eu-central-1"),
    },
})
if err != nil {
    logger.Println(err)
    return nil
}
