Terraform and tagging AWS resources from an external json file-CodePudding

If I had a json file like this:

{
    "allMyTags": {
        "owner": "john",
        "department": "HR",
        "city": "New York"
    }
}

and my AWS provider terraform main.tf looks like this:

resource "aws_vpc" "example" {
  # ... other configuration ...

  tags = {
    owner = "john"
  }
}

How do I go about replacing everything that is in the tags section of main.tf with the external json file. The json file is a lot longer that I have put up there and I just didn't want to manually put in 20 values in the tags section of main.tf. Is there a way to "loop" thru the json file and add it in? Thanks for any help you can provide.

CodePudding user response：

Assuming that you json is already loaded into TF, you could do:

resource "aws_vpc" "example" {
  # ... other configuration ...

  tags = jsondecode(local.myjson["allMyTags"])
}

where local.myjson is the loaded json to TF.
