Workspace naming conventions in Terraform - Mini Project: Build & Apply

Workspace Naming Conventions in Terraform

📖 Scenario: You are managing infrastructure using Terraform. To keep your environments organized, you want to create workspaces with clear and consistent names.Think of workspaces like folders for different projects or environments, such as development, testing, and production.

🎯 Goal: Create Terraform workspace names following a specific naming convention to separate environments clearly.

📋 What You'll Learn

Create a Terraform workspace list with exact names

Add a prefix variable for workspace names

Use a loop to generate full workspace names with the prefix

Output the final list of workspace names

💡 Why This Matters

🌍 Real World

Naming workspaces clearly helps teams avoid confusion and manage multiple environments safely.

💼 Career

Understanding workspace naming conventions is essential for infrastructure as code and collaboration in cloud engineering roles.

1

Create a list of workspace environment names

Create a Terraform variable called environments with the exact list of strings: ["dev", "test", "prod"].

Terraform

# Create a variable called environments with ["dev", "test", "prod"]
# Your code here

Need a hint?

Use variable block with default set to the list.

2

Add a prefix variable for workspace names

Add a Terraform variable called prefix with the exact string value "teamA-".

Terraform

variable "environments" {
  type    = list(string)
  default = ["dev", "test", "prod"]
}

# Add a variable called prefix with value "teamA-"
# Your code here

Need a hint?

Use a variable block with default set to "teamA-".

3

Generate full workspace names with prefix

Create a Terraform local variable called workspace_names that uses a for expression to combine var.prefix and each item in var.environments into a list of full workspace names.

Terraform

variable "environments" {
  type    = list(string)
  default = ["dev", "test", "prod"]
}

variable "prefix" {
  type    = string
  default = "teamA-"
}

# Create local.workspace_names combining prefix and environments
# Your code here

Need a hint?

Use a for expression inside locals to concatenate strings.

4

Output the final list of workspace names

Create a Terraform output called workspaces that outputs the value of local.workspace_names.

Terraform

variable "environments" {
  type    = list(string)
  default = ["dev", "test", "prod"]
}

variable "prefix" {
  type    = string
  default = "teamA-"
}

locals {
  workspace_names = [for env in var.environments : "${var.prefix}${env}"]
}

# Create output workspaces with value local.workspace_names
# Your code here

Need a hint?

Use an output block with value set to local.workspace_names.
