Terraform for Beginners: Hands-On AWS Infra automation

Learn how terraform state tracks resources and outputs, including S3 bucket details, and how terraform apply uses state to create or delete resources via local or remote backends.

Explore how to use the terraform data source to read existing resources, such as security groups and subnets, when provisioning EC2 instances, while noting that it does not create resources.

Explore how to structure Terraform with modules, create an S3 bucket module, and call it multiple times from a root module using variables and outputs during plan and apply.

Discover how Terraform workspaces isolate environments with separate state files, enabling dev, staging, and prod from the same code. Manage workspaces with list, select, and delete commands.

Explore how Terraform provisioners run local and remote commands to configure AWS resources, with a hands-on demo creating an S3 bucket using a local-exec provisioner and Terraform init, plan, apply.

Explore using a Terraform remote provisioner with remote execution to spin up an EC2 instance, run inline commands to install Apache, and set up a key pair and security group.

Copy local files to a remote EC2 instance using Terraform's file provisioner, set permissions, and use remote execution to place an index.html file on the server.

Master Terraform functions to dynamically build names and values using upper, lower, join, min, max, list, and map. Create an S3 bucket name in uppercase that uses workspace via hyphens.

Explore how to use Terraform dynamic blocks to automate repeating ingress rules for a security group by looping over a ports list, enabling scalable AWS infrastructure automation.

Configure terraform remote state with an S3 bucket and DynamoDB to lock state files, prevent conflicts, and support team collaboration.

Learn how to manipulate terraform state with list, show, remove, and mv commands to inspect, rename, and manage the state file for AWS infrastructure without recreation.

Build a basic AWS VPC with public and private subnets, route tables, and an internet gateway using Terraform, and manage remote state with an S3 backend and DynamoDB.
