如何在一个 jenkins 脚本中使用多个 terraform tf 文件？

Question

我正在尝试学习 jenkins 的 terraform 用法。我意识到我不能在同一个 github repository.I 中使用 2 个 tf 文件有 2 个 tf 文件：Providers.tf 和 Provider2.tf

Provider.tf:

#OpenShot Terraform Project
provider "aws" {
  region  = "eu-west-2"
}

resource "aws_s3_bucket" "b" {
  bucket = "my-tf-test-bucket-leanscale-2"
  acl    = "private"

  tags = {
    Name        = "My bucket"
    Environment = "Dev"
  }
}

data "aws_ami" "ubuntu" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }

  filter {a
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}


resource "aws_instance" "web" {
  ami           = data.aws_ami.ubuntu.id
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld-leanscale-2"
  }
}

Provider2.tf:

#OpenShot Terraform Project
provider "aws" {
  region  = "eu-west-2"
}

resource "aws_s3_bucket" "b2" {
  bucket = "my-tf-test-bucket-leanscale-3"
  acl    = "private"

  tags = {
    Name        = "My bucket2"
    Environment = "Dev"
  }
}

data "aws_ami" "ubuntu2" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}


resource "aws_instance" "web2" {
  ami           = data.aws_ami.ubuntu2.id
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld-leanscale-3"
  }
}

詹金斯脚本：

pipeline {
    agent any
    tools {
        
        terraform 'terraform-leanscale'
    }
    
      environment {
    TF_WORKSPACE = 'default' //Sets the Terraform Workspace
    TF_IN_AUTOMATION = 'true'
    AWS_ACCESS_KEY_ID = "${params.AWS_ACCESS_KEY_ID}"
    AWS_SECRET_ACCESS_KEY = "${params.AWS_SECRET_ACCESS_KEY}"
    }

    stages {
        stage('Git Checkout') {
            steps {
               git branch: 'staging', credentialsId: 'leanscale', url: 'https://github.com/yusufkaratoprak/leanscale_yusuf.git'
            }
        }
        
        stage('terraform-init') {
            steps {
                sh label: '', script: 'terraform init' 
            }
        }
        
        stage('terraform-apply') {
            steps {
                sh label: '', script: 'terraform apply --auto-approve' 
            }
        }
        
    }
}

How can OI use multiple tf files in the same repository by Jenkins script?

Answer 1

首先查看该 TF 代码，它可能全部运行在同一个文件中，只有一个提供程序块，因为没有什么要求它在两个单独的文件中。

如果您想要资源的逻辑分离，您可以将提供程序块（在两个文件中相同）移动到另一个文件，可能称为 provider.tf 然后有 resources1.tf 和 resources2.tf（或者 Terraform 不关心的任何东西，只要它具有 .tf 扩展名即可。

但是，如果您出于某种原因希望它位于两个文件中，具有两个提供程序，Terraform 允许提供程序的别名，这样您就可以拥有多个相同的提供程序见 https://www.terraform.io/docs/language/providers/configuration.html#alias-multiple-provider-configurations

或者如果您根本不想更改代码文件

在您的管道中，您可以重命名 provider2，运行 provider1 的阶段。清理 .terraform 文件夹，重命名 provider1 并将 provider2 设置回其正确名称和运行该文件的阶段。

或

将它们放在 Git 仓库中的不同目录中

然后您可以使用 dir 命令切换到每个目录和运行 Terraform

dir("provider1"){
   sh "terraform init"
   sh "terraform apply"

TBH 正确答案是第一个.....将提供者移到它自己的文件中。

编辑：由于行

上的额外 a，您还会收到 providers.tf 第 24 行的错误

filter {a

Answer 2

将此声明移到它自己的文件中而不是复制

provider "aws" {
  region  = "eu-west-2"
}

Terraform 不关心代码使用一个文件还是 100 个文件，但定义必须是唯一的。

Answer 3

查看您的 Terraform 代码提供程序对于这两个文件是相同的。所以通过创建 provider.tf 和只写

来避免冗余

provider "aws" {
  region  = "eu-west-2"
}

next 不要在单独的两个文件中编写代码，而是使用模块结构。通过给一些 awsinstance.tf


    enter code here
    resource "aws_s3_bucket" "b2" {
      bucket = "my-tf-test-bucket-leanscale-3"
      acl    = "private"

  tags = {
    Name        = "My bucket2"
    Environment = "Dev"
  }
}

data "aws_ami" "ubuntu2" {
  most_recent = true

  filter {
    name   = "name"
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }

  filter {
    name   = "virtualization-type"
    values = ["hvm"]
  }

  owners = ["099720109477"] # Canonical
}


resource "aws_instance" "web2" {
  ami           = data.aws_ami.ubuntu2.id
  instance_type = "t2.micro"

  tags = {
    Name = "HelloWorld-leanscale-3"
  }
}

，而不是直接在该目录中使用 variable.tf 传递值。喜欢

    resource "aws_s3_bucket" "b2" {
      bucket = var.bucketname
      acl    = var.acl

}

并在变量文件中

variable "bucketname"{
}

提及所有变量然后在 main.tf 中使用模块“任何名称”并提供上述文件的来源并传递所需的参数。并在这里也提到 variable.tf 并使用

传递值

variable.tfvars

variable bucketname = ""my-tf-test-bucket-leanscale-3"
