There are 2 sides of IAC

1. Configuration Management
2. Orchestration Tool

• Ansible - Configuration management
• Terraform - Orchestration
• Kubernetes - Orchestration is used in containerisation - i.e. Docker, Crio, Rocket.

1. Orchestration tools to configure out instances and their AWS configurations remotely.
2. Terraform files are created with .tf extension
3. Set Environment variables, via Environmental variables and add the ACCESS and SECRET Keys as user variables. Terraform will automatically pick them up.
4. Make sure you refresh any current instances of Git Bash you have running as the environmental variables will not take effect until you have done that. Find the commands to create the instance below.

terraform init

# Check the steps inside the code
# lists either 'SUCCESS' or 'ERROR'
terraform plan

# This runs after everything has been checked 
# Immplements the code (Deploy the infrastructure)
terraform apply
