go - 如何在CircleCI Go图像中使用Terraform

Question

我已经为我的Terraform代码提供了基于Go的自动化测试，我希望它们可以在CircleCI中运行。为此，我为CircleCI提供了以下config.yml:

version: 2

jobs:
  build:
    docker:
      - image: circleci/golang:1.12
      - image: hashicorp/terraform:light

    working_directory: /go/src/bitbucket.org/teapigsteam/findmytea-terraform
    steps:
      - checkout

      - run: go get -v -t -d ./...
      - run: go test -v ./...

但是由于某种原因，Go找不到Terraform可执行文件:

#!/bin/bash -eo pipefail
go test -v ./...

CircleCI received exit code 1

谁能告诉我我在做什么错？也许这只是不可能？

与其尝试使用两个Docker镜像，不如尝试使用hashicorp/terraform:full？

我相信您会看到此错误，因为您的代码正在Golang容器中执行，而该容器无法访问Terraform light容器中的可执行文件。

您可能已经创建了一个自定义Docker镜像来运行该镜像，并手动安装了Terraform。但是，无论如何，hashicorp/terraform:full图像都是建立在Golang图像之上的，因此理论上应该使您更接近目标。
