VRP_Solver Infrastructure as Code (IaC)

The purpose of this repository is to provide the necessary Infrastructure as Code (IaC) scripts to deploy the VRP_Solver project.

Prerequisites

• A DigitalOcean Personal Access Token, which can be created via the DigitalOcean control panel.
• An SSH key named vrp-env added to DigitalOcean and GitHub accounts. The init.yml Ansible Playbook will generate an SSH key pair inside the VRP_IaC directory.
• A personal domain pointed to DigitalOcean’s nameservers.

Ansible Control Node Setup

The Control Node, the machine on which Ansible is installed, is responsible for executing Ansible Playbooks to configure the Ansible Hosts - the target servers that Ansible manages. Unlike other configuration management tools, Ansible is agentless, meaning that it does not require any specialized software to be installed on the Ansible Hosts being managed.

Installation Guide

• Update Packages

  sudo apt update

• Install pip3

  sudo DEBIAN_FRONTEND=noninteractive apt install python3-pip -y

• Install Ansible

  pip3 install ansible

• Clone IaC scripts

  git clone https://github.com/Papajohn77/VRP_IaC.git

• Change Directory

  cd ./VRP_IaC

• Execute Ansible Playbook (change <your_email_address>)

  ansible-playbook -e "email_address=<your_email_address>" init.yml

• Add the contents of the SSH public key tf-digitalocean.pub to your GitHub account. Moreover, add the contents of the SSH public key tf-digitalocean.pub to your DigitalOcean account and give it the name of vrp-env.

  cat tf-digitalocean.pub

• Export Environment Variable (change <your_API_token>)

  export DIGITALOCEAN_TOKEN=<your_API_token>

• Change Directory

  cd ./vrp_env

• Execute terraform apply (change <your_domain_name>)

  terraform apply -var="domain_name=<your_domain_name>" --auto-approve

• Get the IPv4 address of the vrp-env Droplet

  cat vrp-env-ipv4

• Setup the vrp-env Droplet (change <vrp-env-ipv4>, <your_domain_name> & <your_email_address>)

  ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook -u root -i '<vrp-env-ipv4>,' -e 'domain_name=<your_domain_name>' -e 'email_address=<your_email_address>' -e 'pub_key=../tf-digitalocean.pub' --private-key ../tf-digitalocean setup.yml
