如何将 terraform 输出放入 GITHUB_ENV

Question

我有以下地形代码：

provider "aws" {
  region = "eu-central-1"
}

terraform {
  backend "s3" {
    bucket = "aws-project-terra"
    key    = "tf-state"
    region = "eu-central-1"
  }
}



module "ec2" {
  source = "./modules/ec2"

  ami           = "ami-0d1ddd83282187d18"
  instance_type = "t2.micro"
}

我通过 github 操作运行：

name: Terraform-ansible-apply

on:
  workflow_dispatch:

jobs:
  Terraform:
    name: Terraform Plan & Apply
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@v2

      - name: Terraform Setup
        uses: hashicorp/setup-terraform@v1

      - name: Terraform Init
        run: terraform init
        working-directory: ./Terraform
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

      - name: Terraform Validate
        run: terraform validate
        working-directory: ./Terraform

      - name: Terraform Apply
        id: tf-apply
        run: terraform apply -auto-approve
        working-directory: ./Terraform
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

      - name: Save Terraform Outputs
        id: save-outputs
        run: |
          echo 'sg=$(terraform output -raw ec2_sg)' >> "$GITHUB_ENV"
        working-directory: ./Terraform

      - name: Use the value
        id: step_two
        run: |
          echo ${{ env.sg }} 

问题是我在最后一步中没有获得环境变量 env.sg 。 我收到错误：

Run echo $(terraform output -raw ec2_sg) 
/home/runner/work/_temp/a9903635-fab4-4149-89fe-056eb08152ef/terraform-bin output -raw ec2_sg 
 Warning: No outputs found 
  
 The state file either has no outputs defined, or all the defined outputs 
 are empty. Please define an output in your configuration with the `output` 
 keyword and run `terraform refresh` for it to become available. If you are 
 using interpolation, please verify the interpolated value is not empty. You 
 can use the `terraform console` command to assist.

我在 github 工作流程日志中看到输出：

Outputs:

ec2_sg = "sg-015sdf8ad839881"
instance_ip = "3.75.232.345"
subnet_id = "subnet-05d345458f6c1a9"

我也可以从命令行打印输出：

terraform output -raw ec2_sg
sg-01599f8ad873c9881

那么为什么我不能通过 github 环境变量使用这个输出？

Answer 1

您需要在

setup-terraform

操作中将 terraform_wrapper 设置为 false。有一个未决问题 https://github.com/hashicorp/setup-terraform/issues/20 可以更改此行为。

Answer 2

尝试将此部分添加到您的管道中

env:
  ec2_sg: ""
