terraform-provider-errorcheck

A custom terraform provider that can be used to do complex validation during planning and validation

Installation:

If you want to use the script directly from this repo: curl -sSL https://raw.githubusercontent.com/rhythmictech/terraform-provider-errorcheck/master/update-provider.sh | bash

Otherwise you can download update-provider.sh and run it locally

example:

code:

locals {
  compare     = "success"
  testSuccess = "success"
  testFail    = "fail"
}

resource "errorcheck_is_valid" "shouldMatch" {
  name = "check_something"
  test = {
    assert = local.compare == local.testSuccess
    error_message = "Your assertion is not valid"
  }
}

resource "errorcheck_is_valid" "Not_valid_if_not_match" {
  name = "Should not match"
  test = {
    assert = local.compare == local.testFail
    error_message = "Your assertion is not valid"
  }
}

output:

terraform validate .

Error: Your assertion is not valid
