Terraform Level 3 Task 10 Managing Terraform Workspaces

[amaruxia]

Hi Support Team,

Can someone please review this task? I get the following error message:

“Dev workspace API Gateway names are incorrect or missing”

However, I think I’ve created them correctly see the following screenshots and code snippets:

locals {
env = terraform.workspace
api_names = var.KKE_API_NAMES
api_gw = local.env == “dev” ? [local.api_names[0]] : local.env == “prod” ? [local.api_names[1]] : []
}

resource “aws_api_gateway_rest_api” “devops_api_gws” {
count = length(local.api_gw)
name = “${local.env}-${local.api_gw[count.index]}”

provisioner “local-exec” {
when = create
command = “echo "Created API Gateway ${self.name} in workspace ${terraform.workspace}" >> apigateway.log”
}
}

resource “aws_cloudwatch_log_group” “devops_log_groups” {
count = length(local.api_gw)
name = “/aws/apigateway/${aws_api_gateway_rest_api.devops_api_gws[count.index].name}”

provisioner “local-exec” {
when = create
command = “echo "Created Log Group ${self.name} in workspace ${terraform.workspace}" >> loggroups.log”
}
}

variable “KKE_API_NAMES” {
description = “Workspace API names”
type = list(string)

validation {
condition = length(var.KKE_API_NAMES) >= 2
error_message = “Provide at least two API names, e.g., ["devops-api-1","devops-api-2"].”
}
}

output “kke_api_gateway_names” {
description = “API Gateway names created in the current workspace”
value = [for api in aws_api_gateway_rest_api.devops_api_gws : api.name]
}

output “kke_log_group_names” {
description = “CloudWatch Log Group names created in the current workspace”
value = [for log in aws_cloudwatch_log_group.devops_log_groups : log.name]
}

terraform.tfvars

KKE_API_NAMES = [“devops-api-1”, “devops-api-2”]

Hi @amaruxia

I’ve just checked it and it’s worked properly from my end. Please refer to my main.tf file

# Get the current workspace
locals {
  workspace = terraform.workspace
}

# Create API Gateway REST APIs using count
resource "aws_api_gateway_rest_api" "this" {
  count = length(var.KKE_API_NAMES)
  name  = "${local.workspace}-${var.KKE_API_NAMES[count.index]}"

  lifecycle {
    create_before_destroy = true
  }

  provisioner "local-exec" {
    command = "echo 'Created API Gateway ${self.name} in workspace ${local.workspace}' >> /home/bob/terraform/apigateway.log"
  }
}

# Create matching CloudWatch Log Groups
resource "aws_cloudwatch_log_group" "this" {
  count = length(var.KKE_API_NAMES)
  name  = "/aws/apigateway/${local.workspace}-${var.KKE_API_NAMES[count.index]}"
  retention_in_days = 30

  provisioner "local-exec" {
    command = "echo 'Created Log Group ${self.name} in workspace ${local.workspace}' >> /home/bob/terraform/loggroups.log"
  }
}

Raymond,

Thanks for the quick response. I understand the error I made. I misinterpreted the lab question and was thinking it needed one API per workspace instead of creating all APIs in the list. DOH!

Thank you for your assistance, you guys are awesome!

Regards,

Amaru

Two suggestions in this lab, one: make the logged message clear because the lab validation expected a specific message while the lab itself doesn’t request that

two: make it clear that you want two resource for each workspace because the example in the task is confusing

I concur this. Instructions are not very clear on several tasks. The verbiage used should be updated correctly to what exactly the task validations are expecting.
