Terraform Masterclass with AWS (0.14). DevOps IaC Handson

Compare traditional infrastructure with terraformed setups and introduce Terraform as infrastructure as code, explaining the terra and form origins and how it helps transform infrastructure for software deployment.

Explore the five-step Terraform coding flow from building infrastructure knowledge and experience to init, plan, and apply, including dry runs and best practices to avoid errors.

define infrastructure with terraform resource blocks, configure providers and attributes for instances, plan and apply to create and destroy resources, and explore outputs and provider docs.

Learn how to access resource attributes and exported attributes in Terraform using the resource type, name, and attribute syntax, with examples like private ip and public dns.

Define input variables in Terraform with a variable block and externalise values to avoid hard coded strings, including an image_id variable with string type, a default value, and optional description.

Define variables with a variable block and learn to access input variables in Terraform, enabling you to manage AWS infrastructure as code in this module.

Learn to inject external values into terraform variables using tfvars, override default image_id with a var-file, and deploy via plan and apply in an IaC hands-on session.

define an output variable in terraform, use an output block to expose an instance ip address, and verify outputs after running terraform init, plan, and apply.

Explore using local variables in Terraform with a locals block, compare with input variables, and see how to reference image id across resources.

Explore advanced Terraform syntax, including conditional expressions and the ternary operator, for loops, dynamic blocks, and complex objects like maps and nested maps.

Learn to use for loops in Terraform to iterate lists and maps, with square brackets for lists and squiggly braces for maps, including the upper function to uppercase items.

Master Terraform dynamic blocks to iterate over lists and maps, generating scalable security group ingress rules from input variables and ports in an elastic beinstock environment.

Explore complex objects in Terraform by comparing object and map types, define predefined attributes with mixed types, and understand how defaults and outputs behave during plan and apply.

Explore complex types in Terraform, including maps of maps and lists of nested maps, and learn to access nested attributes using lookup, keys, and list indexing.

Learn to read local files into Terraform using a data template file, render with the file function, and leverage AWS Systems Manager Run Command to execute scripts on EC2.

Explore Terraform built-in functions in the Terraform console, covering numeric, string, and collection operations like absolute, ceiling, floor, lower, split, trim, substring, length, lookup, file, concat, flatten, element, and merge.

Create an EC2 in a public subnet of the default VPC using Terraform v1, then evolve with tfvars for externalized values, modules, and outputs toward private subnets and custom VPCs.

Explore using a default value for a Terraform variable to avoid prompts, compare v1 and v2 configurations, and review init and destroy steps in a hands-on demo.

Learn to externalize Terraform variable values with a .tfvars file, replacing defaults and enabling prompts for missing region and the risk profile values during terraform init.

Launch EC2 in a private subnet by configuring a custom subnet with a subnet ID in a VPC, ensuring non-overlapping CIDR blocks and private deployment.

Modularize terraform configurations by splitting resources, variables, and providers into separate files in v5, preserving plan consistency and minimizing blast radius while following the single-responsibility principle.

externalize all hard-coded values by moving string literals and booleans to an external file, adopting v6 style and guiding a cleaner injector-based Terraform setup.

Launch an EC2 instance in a custom VPC and private subnet using Terraform, with minimal attributes for demonstration purposes, highlighting VPC and subnet resource setup.

Explore how to modularize Terraform configurations with root and submodules, including remote modules, to organize VPC resources, dynamic blocks, and input variables while reducing blast radius.

Terraform module anatomy: explore root level and nested modules, and how compute and network submodules like VPC and subnets enable reusable, hierarchical infrastructure code.

Explore local modules in Terraform by declaring module sources, injecting root-level variables, and reusing code across environments to configure VPCs and security groups from within other modules.

Leverage a remote module to provision a VPC architecture in aws by reusing prebuilt code, configuring subnets, internet gateway, and optional resources via input variables and defaults.

Explore two Terraform approaches to create an IAM role: build a custom inline policy and attach it, or use a remote module for a cleaner, reusable policy.

Create an IAM role and policy with a Terraform remote module, using module examples and inputs to externalize policies and bind them to an assumable role for users and services.

Learn how terraform init initializes the project, downloads provider plugins and remote modules into a local hidden .terraform folder, and creates module folders for deployment.

Configure Terraform remote state in a remote bucket to store infrastructure state centrally so multiple developers can work concurrently, and enable state locking to prevent concurrent edits.

Configure a remote Terraform backend by creating a unique S3 bucket, set up a DynamoDB table for state locking, and enable server-side encryption for secure state management.

Configure and test a terraform remote backend using an S3 bucket and DynamoDB table for state storage and locking, initialize, plan, and apply while verifying remote state and lock behavior.

Learn to configure multiple backends by externalizing backend settings with a config file and using the init command line to inject backend values.
