Terraform learning roadmap

This track is organized to help you learn Terraform in a practical order: start with why infrastructure as code matters, get comfortable with Terraform syntax and workflow, then move into local providers, cloud provisioning, reusable modules, and Kubernetes-oriented platform automation.

Phase 1: Foundations and Terraform workflow

Start with why Terraform exists and how it fixes manual, click-driven infrastructure work.
Learn the core Terraform workflow: init, plan, apply, and destroy.
Understand providers, resources, variables, outputs, state, backends, and modules before building larger configurations.
Treat Terraform as code that should be versioned, reviewed, validated, and scanned just like application code.

Phase 2: Fast feedback with local infrastructure

Use the Docker provider to see Terraform create something real with minimal setup.
Practice the workflow on a local container before introducing cloud credentials, networking, or billing.
Focus on reading plans and understanding how resource blocks map to actual infrastructure objects.

Phase 3: Cloud provisioning on GCP and Azure

Move from local experiments to real cloud resources.
Start with a simple GCP VM example so provider configuration, compute resources, and startup scripts feel concrete.
Review the Azure VM example to understand networking, public IPs, security groups, and machine provisioning in a second cloud.
Compare how the same Terraform patterns show up across providers even though the resource types differ.

Phase 4: Reuse, modules, and multi-cloud structure

Learn how modules help you split Terraform into reusable building blocks.
Review the modular GCP VM example to see how root modules and child modules work together.
Study the multi-cloud example to understand one root configuration orchestrating provider-specific modules.
Treat this phase as the bridge from tutorials to maintainable team-scale Terraform codebases.

Phase 5: Kubernetes and platform automation

Learn how Terraform can manage Kubernetes resources through the Kubernetes provider.
Use the Minikube example to connect Terraform concepts to namespaces, deployments, and services.
Finish with an AKS provisioning example so you can see Terraform manage both cluster infrastructure and platform building blocks.
Understand where Terraform fits well in platform workflows and where Kubernetes-native tools still complement it.

How to use this track

Read the section overview lessons first, then inspect the .tf files they reference.
Run terraform fmt, terraform validate, and terraform plan as you work through examples.
Keep credentials and state management in mind when adapting these examples to real environments.
Add future topics by dropping markdown lessons or code examples into the correct numbered section so the roadmap stays intentional.
