Use this repository for you to start understand key concepts of Ansible.

Terraform for provisioning servers on AWS

1. Change profile name in c1-versions.tf
2. Configure the instance type, key pair and instance count based on your requirement in ec2instance.auto.tfvars
3. Configure aws region in terraform.tfvars

// Deploy the architecture and get IP address for EC2 instances in the output
cd terraform
terraform init
terraform validate
terraform plan
terraform apply -auto-approve

// Destroy the architecture
terraform destroy -auto-approve

Inventory

Inventory file is the place you configure the servers. Get the public IP from the terraform output and make sure you have the correct key file.

Playbook

Playbook is the recipe including destination hosts and the automation processes. This example is to install a LAMP stack on and EC2 instance.

ansible-playbook [playbook.yaml] -i [inventory_file]

Tasks

Tasks include the steps (In order) that Ansible is doing to the hosts.

Modules

The modules within tasks we are using in this playbook include:

• yum
• command
• service
• copy

There are tons of modules can be used.

Roles

Use ansible role to define the group of actions which can be reused. (This is just my own understanding)
