如何使用Golang为Lambda函数提供配置值

How to provide config files along with the lambda function written in golang. I created a folder named config inside the project root and provided the config.But unfortunately that doesn't worked after the project got build.And I know this is because of we are building it as a binary file.So, What was the best way or approach to provide config files along with the lambda function for golang?

var config map[string]string
var filename string

//Checks the stage and loads the Configuration file
if len(event.Stage) > 0 {
    filename = "configs/config.json"
}

configFile, err := os.Open(filename)
defer configFile.Close()
if err != nil {
    log.Printf(err.Error())
    return config, err
}
jsonParser := json.NewDecoder(configFile)
err = jsonParser.Decode(&config)
return config, err

    Add the config files to the zip containing the Go binary

    For example, assuming you have a Handler.go with a configs directory containing configs.json then

    go build -o Handler Handler.go && chmod +x Handler && zip -r handler.zip Handler configs
    

    should make a zip containing the configs directory and the Handler binary which can be uploaded to Lambda

    There are alternatives to using files such as AWS Parameter Store that you may wish to consider
