Teraform cannot find Resource for variable despite having it declared in the same file

0 votes

Terraform is not able to find a resource which is declared in the same file where the reference is.

It seems that this line is causing trouble: role_arn = "${aws_iam_role.newsapi_lambda_codepipeline.arn}". It can't find newsapi_lambda_codepipelinewhich is declared as resource "aws_iam_role" "newsapi_lambda_codepipeline" { ... }.

This is my main.tf:

resource "aws_s3_bucket" "newsapi_lambda_builds" {
  bucket = "newsapi-lambda-builds"
  acl    = "private"
}

resource "aws_iam_role" "newsapi_lambda_codebuild" {
  name = "newsapi-lambda-codebuild"

  assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "s3:GetObject",

      ],
      "Resource": "arn:aws:s3:::newsapi_lambda_builds",
      "Effect": "Allow"
    },
    {

  ]

}
resource "aws_iam_role" "newsapi_lambda_codepipeline" {
  name = "newsapi-lambda-codepipeline"

  assume_role_policy = <<EOF

    action {
      name            = "Build"

      role_arn = "${aws_iam_role.newsapi_lambda_codebuild.arn}"

      configuration {
        ProjectName = "newsapi-lambda"
      }
    }
  }
}

After executing terraform apply I get:

Error: Error running plan: 1 error(s) occurred:

* aws_codepipeline.newsapi_lambda: 1 error(s) occurred:

* aws_codepipeline.newsapi_lambda: Resource 'aws_iam_role.newsapi_lambda_codepipeline' not found for variable 'aws_iam_role.newsapi_lambda_codepipeline.arn'


I have aws_iam_role.newsapi_lambda_codepipeline declared, haven't I? DOnt know why its happening, can anyone help?

I think role declaration that u have entered could be wrong. And terraform was not able to generate an arn because of that, therefore can't find it.

It looks like you also need to create resource "aws_iam_role_policy". See https://www.terraform.io/docs/providers/aws/r/codepipeline.html It's a bit unclear why you'd need to split.

If this isn't working then let me know in the reply.
