Week 5 - Wrap-up

Onboarding

Jump into Week 5 of your TFC onboarding journey and learn about Terraform Modules, Workspaces, Variables, and Git Repo Structure.

Terraform Modules, Workspaces, Variables, and Git Repo Structure.

Learn to provision infrastructure with HashiCorp Terraform

Reuse Configuration with Modules

Read about how Terraform modules make configuration easier to organize, understand, reuse, and share. Learn about the directory structure of a module, and how to call them.

Use modules from the public Terraform Registry to define an Amazon VPC containing two EC2 instances. Select module and root input and output variables, install the modules, and apply the configuration.

Workflow

Interactive lab

Terraform Community Edition

Terraform Cloud

Write a local module to create an Amazon S3 bucket hosting a static website. Create a module directory, write the module configuration, variables, and outputs, and call the module from a root configuration.

Import modules to share securely in Terraform Cloud's free private registry. Fork an example module, tag a version-controlled release, deploy the module into the registry, and use it in a configuration.

Curate modules and providers in your private registry. Track approved modules and providers for your organization's use. 

Deploy development and production versions of an S3-hosted static website. Separate their configuration into files, directories, and workspaces, and explore the architectural trade-offs of each approach.

Learn the architectural recommendations for module creation distilled from engagements with large enterprises using Terraform. Use Terraform module best practices to scope, build, improve and consume Terraform modules.

Working with Terraform involves managing collections of infrastructure resources, and most organizations manage many different collections.

Manage Terraform State

Use configuration to import existing infrastructure into Terraform. Review important considerations when bringing infrastructure under Terraform management.

Collaborate using Terraform Cloud

Migrate a state file to Terraform Cloud for secure storage and easy collaboration. 

Create an EC2 instance and security group, and move a resource to another state file. Remove, replace, and re-import resources to manage state and reconcile drift in your infrastructure.

Apply changes to an AWS S3 bucket and bucket objects using resource targeting. Target individual resources, modules, and collections of resources to change or destroy. Explore how Terraform handles upstream and downstream dependencies.

Write Terraform Configuration

Interpret and fix a Terraform configuration with common configuration language errors and deploy an EC2 instance with security groups in AWS. Learn best practices for logging application errors and reporting bugs.

Create an AWS instance and security group. Manually change the instance to create drift in your Terraform state file. Reconcile your state drift and import your resources while avoiding downtime.

Create an AWS instance and security group. Update your configuration with lifecycle management blocks to prevent resource deletion, create resources before destroying them, and ignore changes to specific resource attributes.

Deploy an EC2 instance to a Terraform Cloud workspace and use the Terraform API to interact with and update state.

Use refresh-only plans and applies to update Terraform state to match real-world infrastructure. Understand the implicit refresh behavior in Terraform plan and apply operations.

If you're accustomed to running Terraform from your workstation, the way Terraform Cloud manages runs can be unfamiliar.
