DEPLOYMENT SYSTEM OF MACHINES - SINTESI 25

To create the virtual machines (VM) of our project we will use Vagrant with a file Vagrantfile, where we define all the necessary configurations.

At first, we will use the option –provision to lift the machine. This ensures that all the scripts and settings we put in the Vagrantfile are applied correctly during the initial creation of the MV.

Once the machine is created and configured, no need to use again –provision every time we launch it, since the settings only need to be applied the first time.

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

# DNS

config.vm.define "DNS" do |dns|

dns.vm.box = "rockyinfo"

dns.vm.hostname = "dns"

dns.vm.network "public_network", type: "dhcp"

dns.vm.provision "shell", inline: <<-SHELL

echo "Configuring DNS server"

SHELL

end

# DHCP

config.vm.define "DHCP" do |dhcp|

dhcp.vm.box = "rockyinfo"

dhcp.vm.hostname = "dhcp"

dhcp.vm.network "public_network", type: "dhcp"

dhcp.vm.provision "shell", inline: <<-SHELL

echo "Configuring DHCP server"

SHELL

end

# WEB

config.vm.define "WEB" do |web|

web.vm.box = "rockyinfo"

web.vm.hostname = "web"

web.vm.network "public_network", type: "dhcp"

web.vm.provision "shell", inline: <<-SHELL

echo "Configuring WEB server"

SHELL

end

# DB

config.vm.define "DB" do |db|

db.vm.box = "rockyinfo"

db.vm.hostname = "db"

db.vm.network "public_network", type: "dhcp"

db.vm.provision "shell", inline: <<-SHELL

echo "Configuring BBDD server"

SHELL

end
