How to Setup Ubuntu 20.04 LTS on a Vagrant Virtual Box

This article will teach you how to set up Ubuntu 20.04 LTS on a Vagrant virtual box. It will also show how to configure the Virtual box to suit your preferences. Once we’re done with installation and configuration, I will show you how to move the ip configuration file from your virtual machine to your host machine. If you’ve read this far, thank you for taking the time. This is one of my first tutorials and I’d love to hear your thoughts in the comments. Let’s get to it. To begin, you need to go to the official vagrant website and download vagrant on your host or the local machine. Once you’re done with the download, the installation is pretty straightforward forward just follow the onscreen prompts. To confirm whether or not it has been installed, go to your terminal/cmd depending on the type of machine you’re using. vagrant You should see something like this: achebe@okechukwus-MacBook-Pro ~ % vagrant Usage: vagrant [options] [ ] -h, --help Print this help. Common commands: autocomplete manages autocomplete installation on host box manages boxes: installation, removal, etc. cloud manages everything related to Vagrant Cloud Once you’re done with this, the next step is to setup the virtual box on your machine. For ease, it will make sense if all the installed resources are in one folder. So, we create a folder inside the existing one. like this: achebe@okechukwus-MacBook-Pro ~ % cd Desktop achebe@okechukwus-MacBook-Pro Desktop % mkdir -p TestVagrant/Box/Ubuntu_20_04 achebe@okechukwus-MacBook-Pro Desktop % cd TestVagrant/Box/Ubuntu_20_04 After creating the Ubuntu_20_04 folder inside the ‘Desktop/Testvagrant/Box’ folder, the next step is to install the vagrant ubuntu using the command. like so: vagrant init vagrant init ubuntu/focal64 You should get this output: A Vagrantfile has been placed in this directory. You are now ready to vagrant up your first virtual environment! Please read the comments in the Vagrantfile as well as documentation on vagrantup.com for more information on using Vagrant. Next, start up your virtual machine with this command: vagrant up Once done, you’re set to use your virtual machine with ubuntu inside it. To enter your machine, use this command: vagrant ssh You should get this output: Welcome to Ubuntu 20.04.4 LTS (GNU/Linux 5.4.0-122-generic x86_64) Documentation: https://help.ubuntu.com Management: https://landscape.canonical.com Support: https://ubuntu.com/advantage System information as of Wed Aug 10 23:19:29 UTC 2022 System load: 0.01 Processes: 118 Usage of /: 4.1% of 38.70GB Users logged in: 0 Memory usage: 23% IPv4 address for enp0s3: 10.0.2.15 Swap usage: 0% 0 updates can be applied immediately. To make sure that your virtual machine is indeed running ubuntu, type this command: hostnamectl' I got this result on my own end: vagrant@ubuntu-focal:~$ hostnamectl Static hostname: ubuntu-focal Icon name: computer-vm Chassis: vm Machine ID: 87a9bd2baeb54bcda24765b89147565a Boot ID: 3b9ba20e3d494ac89568bb487c447a7f Virtualization: oracle Operating System: Ubuntu 20.04.4 LTS Kernel: Linux 5.4.0-122-generic Architecture: x86-64 As it is, we’re done with the installation of Ubuntu on our virtual machine. The next thing to do is to explore configuration. For instance, setting our private network set to dhcp. To get the IP address of your virtual machine, use . iconfig If you get this error… vagrant@ubuntu-focal:~$ ifconfig Command 'ifconfig' not found, but can be installed with: apt install net-tools Please ask your administrator. You can easily resolve it with the command. like so: sudo sudo apt install net-tools Then, run the command again and you should get this: iconfig' vagrant@ubuntu-focal:~$ ifconfig enp0s3: flags=4163 mtu 1500 inet 10.0.2.15 netmask 255.255.255.0 broadcast 10.0.2.255 inet6 fe80::52:20ff:fe6d:cccd prefixlen 64 scopeid 0x20 ether 02:52:20:6d:cc:cd txqueuelen 1000 (Ethernet) RX packets 80714 bytes 112088617 (112.0 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 11575 bytes 942445 (942.4 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 49 bytes 4998 (4.9 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 49 bytes 4998 (4.9 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 To configure our vagrant virtual machine (VM) so that it uses dchp as private_network allowing us to give it our own ip, we will need to exit the VM with the command and halt our VM with . exit vagrant halt exit vagrant halt Once you’ve exited the vagrant machine environment, the Ubuntu OS into our location machine folder where the vagrant is installed, a is located in this folder. It is in this that you add your configuration. vagrantfile vagrantfile Add this line of code to your configuration. config.vm.network "private_network", type: "dhcp" This isn’t the end. We also need to make little configurations in the VirtualBox. This is assuming that you’ve installed VirtualBox and it’s working fine on your end. Take the following steps to configure it Select the installed virtual machine. Take note, vagrant automatically creates the VM in the VirtualBox during installation. Select settings, choose network and then select Adapter 2 to add another network adapter. For the “Attached to” dropdown select “Host-only Adapter”. Then, for the “Name” dropdown select “vboxnet0”, then click OK. To see what we just did, enter your VM with the , then run the command. You should notice some new changes. Like this: vagrant ssh ifconfig vagrant@ubuntu-focal:~$ ifconfig enp0s3: flags=4163 mtu 1500 inet 10.0.2.15 netmask 255.255.255.0 broadcast 10.0.2.255 inet6 fe80::52:20ff:fe6d:cccd prefixlen 64 scopeid 0x20 ether 02:52:20:6d:cc:cd txqueuelen 1000 (Ethernet) RX packets 907 bytes 118268 (118.2 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 696 bytes 126192 (126.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 enp0s8: flags=4163 mtu 1500 inet 192.168.56.6 netmask 255.255.255.0 broadcast 192.168.56.255 inet6 fe80::a00:27ff:fec4:dd3d prefixlen 64 scopeid 0x20 ether 08:00:27:c4:dd:3d txqueuelen 1000 (Ethernet) RX packets 24 bytes 11082 (11.0 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 16 bytes 2342 (2.3 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 8 bytes 712 (712.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8 bytes 712 (712.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 shows your new ip address 192.168.56.6. Cool right? enp0s8 The last to do is to transfer the output of into a file, then transfer said file to our local machine - the host. ifconfig Run this command to write the output of into the file that you’ll create. ifconfig ifconfig > ifconfig.txt To send this file to your host machine securely, you need to install vagrant scp. For this installation, take your VM out of the folder where you have vagrant installed and run this command. vagrant plugin install vagrant-scp Once this is done, run this command to transfer the file from the VM to your host machine. vagrant scp default:/home/vagrant/ifconfig.txt ~/Desktop When you check your host desktop, you’ll see where the file is located. ifconfig.txt If you are curious about what default I’m using, it’s the current name of the Virtual Machine. Don’t believe me? Run this command in the vagrant folder. vagrant status Phew! This tutorial was a bit longer than I expected, but we were able to do what we set out to do.
