Hands-On Introduction to InfrastructureAsCode with Terraform

Explore your first Terraform script by configuring an AWS provider, deploying a simple S3 bucket, and using init, plan, apply, and destroy to manage live infrastructure.

Deploy an AWS EC2 instance using variables and outputs, configure the provider, reference AMI ID and instance type via variables, and expose the instance public IP via outputs.

Learn how Terraform state tracks resources, outputs, and code-to-infrastructure mappings, and compare local versus remote state with state locking to prevent conflicts.

Fetch the latest AWS AMI for Ubuntu using a Terraform data block to dynamically read the AMI id. Replace hard-coded AMI values with data sources to streamline EC2 provisioning.

Validate terraform syntax with terraform validate, format code with terraform fmt, then apply changes. See plans show in-place updates versus resource replacements like EC2 renaming or S3 bucket replacement.

Explore how Terraform's built-in functions enable dynamic, reusable configurations, using a random id suffix and lowercased S3 bucket names. See how the console tests functions and inspects resources.

Scale infrastructure with terraform using count and for_each to create multiple S3 buckets and EC2 instances, while using a locals map to assign names and types and output each IP.

Refactor a terraform ec2 config into a reusable module by creating a modules/ec2 folder, moving variables and outputs, and wiring the root module to pass instance map and ami id.

Explore public modules from the Terraform registry to provision an S3 bucket with versioning and access controls, and learn to initialize and apply with targeting to scope changes.

Recap infrastructure as code with Terraform, covering AWS resources like EC2 and S3, and the use of modules, variables, and state management.
