Terraform

Environment to practice IAC for AWS

In order to use the A Cloud Guru playground account and spin up an environment:

Clone this repository to your local machine

git clone [email protected]:EE-Squads-AWS/ACG-Playground-Terraform.git

Create a file called 'terraform.secret.tf' in each layer (ie ./000base/terraform.secret.tf)

Open a Sandbox environment in A Cloud Guru

Store the A Cloud Guru credentials in your secrets file 'terraform.secret.tf'

variable "aws_access_key" {
  description = "The AWS Access Key"
  default     = "**************************"
}

variable "aws_secret_key" {
  description = "The AWS Secret Key"
  default     = "**************************"
}

Alternatively use the Python script 'acg.py' which recursively creates a terraform.secret.tf file in the layer subdirectories

Example

python3 acg.py --access 123456789 --secret 123456789abcdefghijklmnopqrstuvwxyz

Run a terraform initialisation for any layer you want to run 'terraform init'

To apply a layer change your directory to the layer ie ./Terraform/layers/000base and run 'terraform apply'

You don't have to apply all layers, just the 000base layer and any subsequent layer listed in the 'Required layers' section in the main.tf file

Notes:

You will need to download the AWS CLI for the local executions to work

The stored credentials in your secrets file are referenced in the provider block

This repo expects you to have at least terraform version 1.2.0 installed

You don't have to run every layer, just 000base and any 'required layer' listed in the main.tf file

If you are forking this repo ensure to update the module sources in the main.tf files

Each layer stores its own state file relative to the folder

The playground account lasts four hours and after that everything is deleted

The playground doesn’t have any resources when created

A Cloud Guru doesn’t count playground use as activity so your account may end up being marked as ‘inactive’ if you aren’t doing courses/labs.

If you don't destroy your resources you may need to run a 'terraform state rm' next apply when using new access keys in ACG

Common Errors

The below error is caused by a limitation in the ACG playground

Just delete the playground account and re-create a new one

Alternatively use the Python script 'acg.py' which recursively creates a terraform.secret.tf file in the layer subdirectories
