Hello all,
I’ve run into a specific problem while trying to automate a tagging process in terraform. I’ve set an environment variable that is essentially a list of all the tags we’d be using for all resources provisioned in the apply. It looks like this…
export TF_VAR_taglist='{JiraEpic = "ETOS-56","AssignedResearcherPri" = "Isaac",AssignedResearcherSec = "Matt"}'
After setting the environment variable I added a variable called “taglist” in the variables.tf file that grabs the aforementioned environment variable. It looks like this…
variable "taglist"{}
Lastly, I have another locals.tf file where i set a common_tags variable. Like so…
locals { common_tags ="${var.taglist}" }
When i terraform apply, the build fails while trying to map the tags properly. This is the error i receive…
Error: Incorrect attribute value type
on kube_master_worker_nodes_ec2.tf line 9, in resource "aws_instance" "master":
9: tags = local.common_tags
|----------------
| local.common_tags is "{JiraEpic = \"ETOS-56\",AssignedResearcherPri = \"Isaac \",AssignedResearcherSec = \"Matt\"}"
Inappropriate value for attribute "tags": map of string required.
I then decided to define the type of the variable as map(string in the variables.tf file like this
variable "taglist"{ type = map(string) }
I had hoped that this would allow terraform to recognize this variable as a map of strings and not just a string literal, but I was wrong, and these are the errors I get when that definition is applied.
Error: Missing attribute separator
on <value for var.taglist> line 1:
(source code not available)
Expected a newline or comma to mark the beginning of the next attribute.
Error: No value for required variable
on variables.tf line 11:
11: variable "taglist"{
The root module input variable "taglist" is not set, and has no default value.
Use a -var or -var-file command line argument to provide a value for this
variable.
I’m really stuck on this, and I feel like I’m close. Can anyone provide some insight into this and how I should go about solving it?
