iaas-deploy-use-case

A simple IaaS deployment use-case using Terraform.

• An EC2 instance
• An EC2 Security Group

Prerequisites

• Create an AWS AMI User

• Create an AWS EC2 Key Pair

• Install make and tee

• Install bundle (see Install Bundler)

• Install pre-commit (see Install pre-commit)

• Install terraform (see Install Terraform)

How-To

1. Add the AWS credentials for your default and testing environments in ~/.aws/credentials:

[default]
aws_access_key_id={YOUR_ACCESS_KEY_ID}
aws_secret_access_key={YOUR_SECRET_ACCESS_KEY}

[testing]
aws_access_key_id={YOUR_TESTING_ACCESS_KEY_ID}
aws_secret_access_key={YOUR_TESTING_SECRET_ACCESS_KEY}

Assuming you don't alter the settings in the next step, the credentials under testing will be used when testing deployments. Those under default will be used in all non-testing scenarios.

2. Review the settings in terraform-testing.tfvars.json. These will apply only in testing:

{
  "aws_profile": "testing",
  "aws_region": "eu-west-1",
  ...

3. Review the settings in terraform.tfvars (see variables.tf for supported settings and defaults):

{
  "aws_profile": "default",
  "aws_region": "eu-west-1",
  ...

The settings in terraform.tfvars declare user-provided settings and would typically be created on-the-fly.

4. Initialize the repository:

make init

5. Test and deploy the infrastructure:

make all

6. Destroy the infrastructure:

make destroy
