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

Question

我正在尝试使用 jenkins 学习 terraform 的用法。我意识到我不能在同一个 github 存储库中使用 2 个 tf 文件。我有 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 TF 代码，它可以在同一个文件中运行，只需一个提供程序块，因为没有什么要求它位于两个单独的文件中。

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（或任何 Terraform 没有只要它有一个.tf 扩展名就可以了。

但是，无论出于何种原因，如果您希望它位于具有两个提供程序的两个文件中，Terraform 允许提供程序的别名，以便您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 设置回正确的名称，然后运行该文件的阶段。

或

将它们放在 Git 存储库中的不同目录中

然后您可以使用dir 命令切换到每个目录并运行 Terraform

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

TBH 正确答案是第一个.....将提供程序移出到自己的文件中。

编辑： 由于额外的 a 在行上，您还会收到 providers.tf 的第 24 行的错误

filter {a

Answer 2

将此声明移动到其自己的文件中，而不是复制

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

Terraform 不在乎您使用 1 个或 100 个文件作为代码，但定义必须是唯一的。

Answer 3

在查看您的 terraform 代码提供程序时，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。 通过给出一些在模块目录中编写带有上述代码的单个文件 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"
  }
}

，而不是直接使用该目录中的 variable.tf 传递值。 喜欢

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

}

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”并提供上述文件的源并传递所需的参数。并且在这里也提到 variable.tf 并使用传递值

variable.tfvars

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