How to Create a Ansible Lab on your Local Machine using Vagrant in 5 min using ChatGPT - Part 2

Update the above Vagrantfile Centos 8 servers and add Public IP and dhcp on each server ..

To update the provided Vagrantfile for the three CentOS 8 servers to each have a public IP and use DHCP for IP assignment, you'll need to modify the network configuration to use a public network. 

Vagrant can configure your VMs to use a public network, which allows them to access and be accessible from the public internet if your hosting environment supports it. This is often achieved by using DHCP to assign a public IP automatically.

Here's how you can modify the Vagrantfile:

# -*- mode: ruby -*-

# vi: set ft=ruby :

Vagrant.configure("2") do |config|

  # Define the base box

  config.vm.box = "centos/8"

  # Ansible Tower Server

  config.vm.define "ansible_tower" do |ansible_tower|

    ansible_tower.vm.hostname = "ansible-tower"

    ansible_tower.vm.network "public_network", use_dhcp_assigned_default_route: true

  end

  # Deployment Environment 1

  config.vm.define "deploy_env1" do |deploy_env1|

    deploy_env1.vm.hostname = "deploy-env1"

    deploy_env1.vm.network "public_network", use_dhcp_assigned_default_route: true

  end

  # Deployment Environment 2

  config.vm.define "deploy_env2" do |deploy_env2|

    deploy_env2.vm.hostname = "deploy-env2"

    deploy_env2.vm.network "public_network", use_dhcp_assigned_default_route: true

  end

end

This configuration uses public_network and sets use_dhcp_assigned_default_route: true to allow DHCP to assign public IPs to your VMs. Please note, the actual public IP assignment depends on your network setup and the capabilities of your host environment. In some cases, you might need to specify a bridge or make additional configurations to ensure your VMs are accessible from the public internet.

Remember, exposing your VMs to the public internet can have security implications. Ensure that you have appropriate security measures in place, such as firewalls and secure authentication methods.
