Deploy Infra in the Cloud using Terraform

Understand how Terraform describes desired infrastructure and uses providers to manage cloud resources. Relate configuration, execution plans, and state to the deployment workflow.

Explore a first Terraform configuration for Azure resources. Identify the provider and resource blocks and connect their arguments to the infrastructure you want to create.

Locate the course GitHub repository containing the demonstration configurations and supporting examples. Use the relevant folder to follow along and compare your work with the supplied files.

Review the course transition to Terraform 0.14 and the compatibility considerations of a version change. Treat the version shown as historical context when selecting tooling for a current deployment.

Follow the Terraform init, plan, and apply workflow. Distinguish preparing the working directory, previewing proposed changes, and applying infrastructure changes.

Explore how Terraform handles resource changes that require replacement. Read the proposed actions before applying changes so that recreation is not mistaken for an in-place update.

Use Terraform formatting and validation to check configuration before deployment. Distinguish consistent source formatting from configuration validation and from a provider-backed execution plan.

Examine a Terraform configuration for an Azure web app and its supporting hosting resources. Connect resource arguments and references to the application infrastructure being deployed.

Find the source configuration used in the web-app demonstrations. Use the linked course repository to inspect the resource definitions, variables, and outputs alongside the lectures.

Follow deployment of the web-app configuration with Terraform. Compare the planned infrastructure with the deployed Azure resources and use the resulting outputs to inspect the deployment.

Define input variables to make a Terraform configuration reusable. Understand how types, defaults, and references separate environment-specific values from resource definitions.

Supply Terraform input values through tfvars files. Compare this approach with variable defaults and keep environment-specific settings separate from reusable infrastructure code.

Override Terraform input variables from the command line. Understand when explicit deployment-time values are useful and review the selected inputs before applying a plan.

Expose useful deployment results through Terraform outputs. Reference resource attributes so callers and operators can retrieve information without manually inspecting every resource.

Understand what an execution plan describes and why it should be reviewed before apply. Distinguish proposed create, update, replace, and destroy actions.

Follow the execution-plan demonstration and inspect the proposed resource changes. Relate the configuration and current state to the actions Terraform intends to perform.

Understand how Terraform state connects configuration addresses to real infrastructure. Compare local and remote state and consider collaboration, access control, and sensitive information.

Inspect the state-management workflow demonstrated in the course. Relate tracked resource addresses and stored attributes to the infrastructure Terraform manages.

Connect Terraform configuration, state, remote resource observations, and the execution plan. Explain how Terraform determines the difference between the desired and observed infrastructure.

Compare ways to manage development, test, and production infrastructure. Identify which configuration can be reused and which inputs and state must remain environment-specific.

Follow the demonstration of deploying infrastructure for separate environments. Track the selected environment inputs and state rather than assuming every run targets the same resources.

Explore a Terraform deployment that combines a web app and SQL database. Identify the resource relationships and environment inputs needed to assemble the application infrastructure.

Understand Terraform CLI workspaces as separate state instances for one configuration. Consider where this is useful and where stronger environment or credential separation is required.

Follow creation and selection of Terraform workspaces. Observe how changing the selected workspace changes the state context used by subsequent Terraform operations.

Explore the Terraform resources and deployment choices needed to provision an Azure Kubernetes Service cluster. Distinguish creating the cluster infrastructure from deploying applications inside Kubernetes.

Follow deployment of an AKS cluster with Terraform. Connect the configuration and execution plan to the resulting cluster resources.

Examine an infrastructure configuration that combines AKS, Azure Container Registry, and access permissions. Understand why image storage and authorization are separate from cluster creation.

Follow the AKS and ACR deployment demonstration, including the permissions needed for image access. Verify the relationships between the deployed cluster, registry, and assigned identity.

Explore the Terraform resource model for Azure Container Apps. Identify how a declarative infrastructure configuration describes the hosting environment and application deployment settings.

Follow the demonstration of deploying a Container Apps configuration with Terraform. Relate the template inputs and planned actions to the resulting Azure infrastructure.

Explore Terraform configuration for Azure Key Vault and its secrets. Distinguish creating a vault, configuring access, and managing secret values, and consider the sensitivity of Terraform state.

Follow the Key Vault and secret deployment demonstration. Relate the Terraform resources to the vault configuration and the permissions needed to manage its data.

Understand how Azure role-based access control can authorize Key Vault secret operations. Distinguish management-plane permissions from access to the secret values themselves.

Follow the demonstration of Key Vault secret access using RBAC. Connect the assigned identity and role scope to the secret operations being authorized.

Explore how a storage account, blob container, and blob are represented in Terraform. Understand their hierarchy and the references needed to connect the resources.

Follow deployment of the storage account, container, and blob example. Compare the Terraform configuration with the resulting storage objects and their intended access settings.
