Vagrant

Vagrant is an open-source tool that helps us to automate the creation and management of Virtual Machines. In a nutshell, we can specify the configuration of a virtual machine in a simple configuration file, and Vagrant creates the same Virtual machine using just one simple command. It provides command-line interfaces to automate such tasks.

Creating a Common Directory for all VMs

Create a Directory with name vagrantvms

mkdir vagrantvms

Change Directory to vagrantvms

cd vagrantvms

To Bring up VM

UbuntuCentOS

Create a Directory name ubuntu

mkdir ubuntu 

Change Directory to ubuntu

cd ubuntu

Initialize Ubuntu VM

vagrant init ubuntu/bionic64 

Now Bring up your Ubuntu VM

vagrant up

Once your VM is up then login to your vm

vagrant ssh

Now you can see the prompt of the ubuntu machine, If you wanna exit type exit

Create a Directory name centos

mkdir centos 

Change Directory to centos

cd centos

Initialize centos VM

vagrant init geerlingguy/centos7 

Now Bring up your centos VM

vagrant up

Once your VM is up then login to your VM

vagrant ssh

Now you can see the prompt of the centos machine, If you wanna exit type exit
