如何在 CircleCI Go Image 中使用 Terraform

Question

我已经为我的 Terraform 代码进行了基于 Go 的自动化测试，我想让它们进入 CircleCI 中的运行。为此，我为 CircleCI 设置了以下 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 ./...

Exited with code exit status 1
CircleCI received exit code 1

谁能告诉我我做错了什么？或许这是不可能的？

与其尝试使用两张 Docker 图片，不如尝试只使用 hashicorp/terraform:full?

我相信您看到此错误是因为您的代码是在 Golang 容器中执行的，该容器无法访问 Terraform light 容器中的可执行文件。

您可以为运行创建自定义 Docker 图像，然后手动安装 Terraform。然而，无论如何，hashicorp/terraform:full 图像是建立在 Golang 图像之上的，所以理论上应该让你更接近你的目标。
