Question

我在dev_account创建了一个codepipeline，它在dev_account，test_account和prod_account都触发了codedeploy，三个帐户的代码部署看起来相同，只是它们位于不同的帐户中。

以下是我的terraform文件的组织。我使用terraform模块重用代码，但我仍然认为我的代码有很多重复的代码，如何优化它们？

common_infr/
    codepipeline.tf # dev_account has codepipeline, codedeploy 
    codedeploy.tf   
    test_account/
        codedeploy.tf # test_account has a codedeploy
    prod_account/
        codedeploy.tf # prod_account has a codedeploy
pipeline1/
    main.tf #run terraform apply here using dev account
    test_account/
        main.tf #run terraform apply here using test account
    prod_account/
        main.tf #run terraform apply here using prod account

这是pipeline1 / main.tf：

module "pipeline1" {
  source       = "../common_infra"
  variable1    = "..."
  ...
}

这是pipeline1 / test_account / main.tf：

module "pipeline1" {
  source       = "../../common_infra/test_account"
  variable1    = "..."
  ...
}

这是pipeline1 / prod_account / main.tf：

module "pipeline1" {
  source       = "../../common_infra/prod_account"
  variable1    = "..."
  ...
}

三个帐户的codedeploy.tf看起来一样。如何优化这个？

Answer 1

不是为每个帐户的codedeploy.tf创建3个模块，而是创建一个codedeploy模块。在每个帐户的main.tf中，来源codedeploy模块和pass in the account's provider。这是test_account的样子。

provider "aws" {
  alias  = "test_account"
  profile = "your_profile_name_for_test_account"
}

module "pipeline1" {
  providers = {
    aws = "aws.test_account"
  }
  source       = "../../common_infra/codedeploy"
  variable1    = "..."
  ...
}

编辑以详细说明目录布局。最后，您要从codepipeline中移除common_infr并将其放入自己的模块中。

modules/
  codepipeline/
    codepipeline.tf
  common_infr/
    codedeploy.tf

accounts/
  test_account/
    main.tf
  prod_account/
    main.tf

test_account / main.tf：

provider "aws" {
  alias  = "test_account"
  profile = "your_profile_name_for_test_account"
}

module "pipeline1" {
  providers = {
    aws = "aws.test_account"
  }
  source       = "../modules/codepipeline"
  variable1    = "..."
  ...
}

module "common_infr" {
  providers = {
    aws = "aws.test_account"
  }
  source       = "../modules/common_infr"
  variable1    = "..."
  ...
}

prod_account / main.tf：

provider "aws" {
  alias  = "prod_account"
  profile = "your_profile_name_for_prod_account"
}

module "common_infr" {
  providers = {
    aws = "aws.prod_account"
  }
  source       = "../modules/common_infr"
  variable1    = "..."
  ...
}
