💻 Technologies

This project was developed with the following technologies:

• Terraform
• Ansible
• Docker
• Azure
• Redis

Initial Configuration Steps

Note

Preparation steps before manual or automated setup

Clone repository

# Clone the repository
$ git clone https://github.com/jurfest/iac-mba-activity.git

# Go to project's folder
$ cd https://github.com/Jurfest/iac-mba-activity

# Open vscode - if wanted - or continue in the terminal or open another IDE
$ code .

Connect to your Azure account

# Opens a new window to connect to the Azure cloud provider
$ az login

Generate ssh-keys folder

# Create ssh-keygen folder
$ mkdir ssh-keygen

$ cd ssh-keygen

# Generate public and private key files by responding to prompt questions
$ ssh-keygen

$ cd ..

Automated setup

This Bash script automates the deployment of a full-stack application infrastructure using Terraform and Ansible. It provisions and configures a VM instance in Azure using Terraform, then configures the VM with Ansible, and finally executes a set of Docker containers using Docker Compose.

# Ensure Terraform, Ansible, netcat (nc), and jq are installed.
# After running the command bellow you can follow the prompts and monitor the logs for deployment progress.
bash setup.sh

# Remember to destroy infrastructure after use

How to run Terraform and Ansible

To manually provide and configure infrastructure and deploy the full-stack app, you can follow the following steps.

Running Terraform

# Go to terraform folder
$ cd terraform

# Run necessary terraform commands
$ terraform init
$ terraform plan
$ terraform apply -auto-approve
$ cd ..

Running Ansible

# Go to ansible folder
$ cd ansible

# Generate inventory file
$ bash create_hosts.sh

# Run playbook with verbosity
$ ansible-playbook -i inventory.ini playbook.yml -vvv

# Go back to main directory
$ cd ..

🔬 How to inspect the result

Inside the browser:

http://public_ip

Connect to the Virtual Machine using SSH (Linux/Mac):

# Connect to remote VM in the cloud (ssh azureadmin@11.111.111.11 -i ../ssh-keys/swarm-cluster)
$ ssh azureadmin@public_ip -i /path/to/your/private_key

# Verify if the containers are correctly being executed inside de VM
$ docker ps

# Disconnect from VM
$ exit # or press: ctrl + d

Preview

Destroying Infrastructure with Terraform

# Navigate to the Terraform configuration directory
$ cd terraform

# If you haven't already done so, initialize Terraform
$ terraform init

# Optional step to preview the changes Terraform will make to destroy the infrastructure
$ terraform plan -destroy

# Perform the destruction of resources. Terraform will prompt you to confirm this operation
$ terraform destroy

Acknowledgment

This Infrastructure as Code (IaC) exercise is built upon an Azure Sample showcasing a comprehensive full stack application called Azure Voting App.
