🛠️ Set up and verify

  1. Install
    winget install Hashicorp.Terraform
    brew tap hashicorp/tap && brew install hashicorp/tap/terraform
    see developer.hashicorp.com/terraform/install (apt repository)
  2. Editor: Visual Studio Code with HashiCorp Terraform, Bicep, YAML (Red Hat), CloudFormation Linter.
  3. Create main.tf
    output "hello" {
  value = "Hello, GayaGnan!"
}
  4. Run it and check the version
    terraform init && terraform apply   (an output only: nothing is created)
terraform version
  5. Health check: paste what your terminal printed.

Install one language at a time. These commands only install or print versions; nothing here deletes files. Versions change: check the official page and note the version you installed.

🧭 The 14-lab path

  • 00 · Setup and verify — install the runtime and editor, run hello world, print the version, fix PATH
  • 01 · Syntax and trace — follow each line and the value of every variable
  • 02 · Logic — conditionals and decision trees
  • 03 · Loops — trace tables and loop challenges
  • 04 · Functions — break problems down and test each piece
  • 05 · Data structures — lists, maps, stacks, queues and trees you can see
  • 06 · Debugging — bug cases with a hint ladder
  • 07 · Algorithms — search, sort and Big-O comparison
  • 08 · Files and data — read and write fixture files
  • 09 · API or database — talk to a mock API or a sandbox database 🧪 Terraform Plan, Apply & Destroy
  • 10 · Testing — write tests and read failing assertions
  • 11 · Security — secure coding and dependency hygiene for this language 🧪 Policy-as-Code Tag Compliance
  • 12 · Project — one portfolio mini-project
  • 13 · Assessment — quiz, coding test, rubric and an explain-your-answer prompt

🏗️ Mini-projects

  • Deploy preview for a mock VNet/VPC
  • Tagged storage policy
  • Reusable compute module
  • CI pipeline configuration

Projects use synthetic data only.
