Vagrant Lab - Advanced Vagrantfile Configuration

Assign CPU and RAM

1. go into the workshiop folder named vagrantvm

   cd vagrantvm
   

2. now we will assign cpu and memory limit to vagrant box or VM

   CPU: 2
   RAM: 1024MB or 1GB
   

3. open Vagrantfile

   notepad Vagrantfile
   

   and add following lines

   config.vm.provider :virtualbox do |vb|
     vb.customize ["modifyvm", :id, "--memory", 1024]
     vb.customize ["modifyvm", :id, "--cpus", 2]
   end
   

   final content should look like

   Vagrant.configure("2") do |config|
     config.vm.box = "bento/ubuntu-18.04"
     config.vm.hostname = "vm1"
     config.vm.network "private_network", ip: "172.16.1.10"
     
     config.vm.provider :virtualbox do |vb|
       vb.customize ["modifyvm", :id, "--cpus", 2]
       vb.customize ["modifyvm", :id, "--memory", 1024]
     end
   
   end
   
   

   finally save file

4. validate Vagrantfile config

   vagrant validate
   

5. Start VM

   vagrant up
   

6. Goto VirtualBox, and verify CPU and RAM changed accordingly for vagrant managed VM

7. Stop VM

   vagrant halt
   

Share File and sync folder

1. go to workshop folder and create new folder named data

2. create new file named syncedfile.txt inside data folder and create some content in this file

3. go into vagrantvm folder and create new file named copiedfile.txt and create some content in this file

4. modify Vagrantfile to add following lines

   config.vm.synced_folder "../data", "/home/vagrant/data"
   config.vm.provision "file", source: "./copiedfile.txt", destination: "/home/vagrant/copiedfile.txt"
   

   final content should look like

   Vagrant.configure("2") do |config|
     config.vm.box = "bento/ubuntu-18.04"
     config.vm.hostname = "vm1"
     config.vm.network "private_network", ip: "172.16.1.10"
     config.vm.synced_folder "../data", "/home/vagrant/data"
     config.vm.provision "file", source: "./copiedfile.txt", destination: "/home/vagrant/copiedfile.txt"
     
     config.vm.provider :virtualbox do |vb|
       vb.customize ["modifyvm", :id, "--cpus", 2]
       vb.customize ["modifyvm", :id, "--memory", 1024]
     end
   
   end
   
   

   finally save file

5. validate Vagrantfile config

   vagrant validate
   

6. Start VM

   vagrant up
   

7. SSH into VM and verify if copiedfile.txt and data folder exist and syncedfile.txt inside data exist and contents of both file same as in host.

8. Try updating both file on host and on VM and see if changes get synced

9. Stop VM

   vagrant halt
