如何在Terraform资源内创建循环？

Question

相对简单的问题。

我不知道这是terraform可以做的事情，但是我想使用for循环在terraform资源中创建对象。您可以在下面看到我的意思的示例。我已经遍历了资源以创建管道，但是我还想遍历部署对象，因此可以将一个codeCommit存储库推送到多个ECS服务，而不必创建新的管道。这可能吗？

我想循环的部分有：

  

使用多个循环放置多个部署

resource "aws_codepipeline" "pipeline" {
  count    = "${local.numRepo}"
  name     = "${element(var.respository_names, count.index)}-${terraform.workspace}"
  role_arn = "${var.role}"

  artifact_store {
    location = "${element(aws_s3_bucket.artifact.*.bucket, count.index)}"
    type     = "S3"
  }

  stage {
    name = "Source"

    action {
      name             = "Source"
      category         = "Source"
      owner            = "AWS"
      provider         = "CodeCommit"
      version          = "1"
      output_artifacts = ["source"]

      configuration {
        RepositoryName = "${element(var.respository_names, count.index)}"
        BranchName     = "${element(split(",",lookup(var.codepipelines_info,"${terraform.workspace}.${element(var.respository_names,count.index)}")),1)}"
      }
    }
  }

  stage {
    name = "Test"

    action {
      name             = "Test"

      version          = "1"

      configuration {
        ProjectName = "${element(aws_codebuild_project.openjobs_build_test.*.name, count.index)}"
      }
    }

    action { <<<PLACE MULTIPLE DEPLOYMENTS USING SOME FOR LOOP
