Terraform Simplified: Beginner to Pro

Demonstrates Terraform authentication to create an Azure storage account, using storage.tf and the easy login flow, selecting subscription and tenant, and verifying account details.

Explore a hands-on Terraform commands demo covering init, format, validate, plan, apply, and destroy in Azure, including providers and demo RG resource groups.

Explore a practical Terraform state file demo that creates a resource group and storage account in Azure, updates tags, observes state locks, and validates per-project state folders.

Discover how Terraform compares the desired state in your tf file with the current state in Azure, and how plan and apply enforce changes across resource groups.

Explore variable assignment methods in Terraform, including defaults, user input at plan time, command line -var flags, terraform.tfvars files, and environment variables using TF_VAR naming.

Learn to manage Terraform variables by defining them in variables.tf and supplying values through terraform.tfvars or environment-specific files (dev, stage, prod) with -var-file during plan and apply.

Declare a number data type variable named RG_name in Terraform, fix a string mismatch, and run init and apply to create a resource group named one, two three.

Demonstrates using a map data type in Terraform to configure a resource group’s name and location via a variable, with defaults and tfvars overrides, plus init, plan, and apply.

Discover how Terraform meta argument in the life cycle block customizes resource behavior, including ignore_changes for tags, and manages create, destroy, and replacement scenarios.

Learn how the create_before_destroy lifecycle meta argument in Terraform makes Terraform create the new resource first, then destroy the old one, changing the default destroy-then-create behavior.

Leverage dynamic blocks in Terraform to create five security rules for a network security group, including inbound and outbound configurations.

Explore end-to-end infrastructure deployment with Terraform provisioners, including local-exec, remote-exec, and file provisioners, to install software like nginx and manage configuration after virtual machine creation.

Discover how Terraform taint marks a manually changed resource as tainted, forcing delete and recreate on the next apply.

Explore creation-time provisioner behavior in Terraform, showing how a failed provisioning can taint a resource and trigger recreation, and how on_failure = continue avoids taint by skipping errors.

Learn how to debug terraform by enabling tf_log levels (trace to error), running init and plan, and routing logs with tf_log_path for the Azure MX provider workflows.

Learn to build a Terraform module for Azure RM Windows virtual machine, including main.tf, providers.tf, and variables for vnet, rg name, and vm config, then test deployment.

Clone the linux vm module from the Azure repo into your local machine, configure provider and variables in main.tf, then run terraform init, plan, and apply to provision the vm.

Learn how to manage Terraform remote state with centralized backends, replacing local state file storage with Azure Blob Storage and other options for team collaboration.

Create an Azure repo, add main.tf from the state file demo, configure the linux vm module with runtime values, and enable Azure RM remote state with a storage container.

Explore basic ci/cd for terraform by building an Azure DevOps pipeline that runs terraform init, plan, and apply with remote state in an Azure storage account and Azure Repos.

Demonstrates a two-stage ci/cd pipeline for terraform, separating plan and apply, with environment approvals and a variable group to manage configuration and an artifact-driven apply.

Demonstrates creating a sentinel policy for Terraform Cloud that requires all resources to have tags, attaching it to a policy set, and enforcing it during plan and apply.
