Live Infrastructure Example

Description

This code is used to deploy an AWS EC2 instance as well as an Amazon Virtual Private Cloud (VPC).

Requirements

These are the requirements for this module.

	Terraform
>=	1.0.11

	Terragrunt
>=	0.31.0

Setup

1. Clone terraform modules repository at the top level directory

git clone [email protected]:flugel-it/workshop-live-infra.git

2. Configure your environment with the correct AWS profile

export AWS_PROFILE=<profile name>

3. Optional: Initialize each environment's resource you're going to work on

• To initialize all the resources

./scripts/initialize.sh <environment> # environment: dev, staging

• To initialize only one resource

cd <environment>/<resource>  # ex: dev/vpc
terragrunt init

Terragrunt takes care of creating the appropiate resources for tracking infrastructure state remotely.

4. Review the changes to be applied

• For the whole environment

cd <environment>/  # ex: dev/
terragrunt run-all plan

• For only one resource

cd <environment>/<resource>  # ex: dev/vpc
terragrunt plan

5. Apply your changes

• For the whole environment

cd <environment>/  # ex: dev/
terragrunt run-all apply

• For only one resource

cd <environment>/<resource>  # ex: dev/vpc
terragrunt apply

Region

The deploy region is configured on a per-environment basis, and loaded in the root terragrunt.hcl config on execution.

This region configuration is held in each environment directory's env.hcl file, and can be modified as follows:

// dev/env.hcl
// ...
locals {
  aws_region = "us-east-1"
  // ...
}
//...
