将 JSON 字符串解码为地形图 [英] Decoding JSON string to terraform map

问题描述

我正在使用 HTTP 数据源从中检索数据内部服务.服务返回 JSON 数据.

I'm using the HTTP data source to retrieve data from an internal service. The service returns JSON data.

我无法插入返回的 JSON 数据并在其中查找数据.

I can't interpolate the returned JSON data and look up data in it.

例如:

模块 A

data "http" "json_data" {
    url = "http://myservice/jsondata"

    # Optional request headers
    request_headers {
       "Accept" = "application/json"
    }
}

output "json_data_key" {
    value = "${lookup(data.http.json_data.body, "mykey")}"
}

main.tf

provider "aws" {
   region = "${var.region}"
   version = "~> 0.1"
}

module "moduleA" {
   source = "../../../terraform-modules/moduleA"
}

resource "aws_instance" "example" {
    ami = "ami-2757f631"
    instance_type = "${module.moduleA.json_data_key}"
}

查找函数将无法提取 JSON 数据中的键.

The lookup function will fail to extract the key within the JSON data.

有没有办法将 JSON 数据解码为地形图?

Is there any way to decode the JSON data into a terraform map ?

推荐答案

好的，看来这样做的方法是使用外部数据，因为它返回一个 map一个json响应.https://www.terraform.io/docs/providers/external/data_source.html

Ok, so it seems to be that the way to do the is by using the external data, as it return a map from a json response. https://www.terraform.io/docs/providers/external/data_source.html
