In week 3 of your onboarding journey, you’ll learn the basics of Terraform.

In week 3 of your onboarding journey, you'll learn the basics of Terraform.

Learn to provision infrastructure with HashiCorp Terraform

Write Terraform Configuration

Create an EC2 instance, then use the Terraform Registry to create a security group to make it publicly accessible. Learn how Terraform resources define infrastructure as code through arguments, attributes, and dependencies.

Call APIs with Custom SDK Providers

Learn how Terraform providers interact with resources by serving as a bridge between Terraform and target APIs.

Customize infrastructure for a web application with Terraform. In this tutorial, you will use Terraform input variables, including lists, maps, strings, and booleans, to make the configuration for your infrastructure more flexible.

Protect sensitive values from accidental exposure using Terraform sensitive input variables. Provision a web application with Terraform, and mark input variables as sensitive to restrict when Terraform prints them out to the console.

Use Terraform local values to simplify your configuration and avoid duplication of reused expressions.

Use output values to export data about the resources Terraform manages.  Hide sensitive output values.

Use a data source to configure an EC2 instance with an appropriate AMI for the current region. Use a remote state data source to share data between Terraform projects and to support multiple availability zones.

Workflow

Terraform Cloud

Terraform Community Edition

Create an implicit dependency between an EC2 instance and its Elastic IP using variable interpolation. Create explicit dependencies on an S3 Bucket and SQS Queue with depends_on. Learn how Terraform creates independent resources in parallel.

Manage similar Terraform resources using the count argument. Create a VPC with a load balancer and EC2 instances. Then use count to manage a configurable number of similar AWS EC2 instances across multiple subnets.

Provision similar infrastructure components by iterating over a data structure with the for_each argument. Duplicate an entire VPC including a load balancer and multiple EC2 instances for each project defined in a map.

Use templatefile and lookup functions to generate dynamic user data for an EC2 instance and find a region-specific AMI. 

Make your Terraform configurations more dynamic and reusable with expressions. Use locals to assign expressions to variables for reuse, conditionals to declare if/then scenarios, and the splat expression to return attributes from complex value types.

Manage your provider versions using the dependency lock file. Use version constraints to filter provider versions compatible with your configuration. Update your lock file to use a new provider version.

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.

Update an existing configuration to work with a newer version of Terraform. Use the required_version setting to pin the Terraform versions for your projects. Manage different versions of Terraform across your team.

Use the configuration-driven workflow to change Terraform resource IDs. Refactor configuration to move resources into modules using the `moved` block.

Collaborate using Terraform Cloud

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

Manage Terraform State

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