Demo: Preparing Kops install
First, we will setup a vagrant, and provision an Ubuntu Vm using vagrant and virtualbox.
Following are the steps to setup kops installation.
Step #1: Downlaod and install Virtualbox as per your platform – https://www.virtualbox.org/wiki/Downloads
Step #2: Download and install vagrant as per your platform – https://www.vagrantup.com/downloads.html
Note: Below steps are tested on MacOS.
Step #3: Create a directory named ubuntu-box, and goto that directory using below command.
$ mkdir $HOME/ubuntu-box
$ cd $HOME/ubuntu-box
Step #4: Run below commands to run Ubuntu Virtual machine. (On Vagrant website, you can find other boxes as well, if you want.)
vagrant init will create a Vagrantfile
$ vagrant init ubuntu/xenial64
vagrant up will use Virtualbox to setup this ubunut/xenial64 box for you.
This might take couple of minutes
$ vagrant up
Output:
➜ ubuntu-box vagrant up Bringing machine 'default' up with 'virtualbox' provider... ==> default: Importing base box 'ubuntu/xenial64'... ==> default: Matching MAC address for NAT networking... ==> default: Checking if box 'ubuntu/xenial64' version '20191024.0.0' is up to date... ==> default: A newer version of the box 'ubuntu/xenial64' for provider 'virtualbox' is ==> default: available!

Now do vagrant ssh-config to login to the virtual machine.
$ vagrant ssh-config
Output:
➜ ubuntu-box vagrant ssh-config Host default HostName 127.0.0.1 User vagrant Port 2222 UserKnownHostsFile /dev/null StrictHostKeyChecking no PasswordAuthentication no IdentityFile /Users/sushiver/ubuntu-box/.vagrant/machines/default/virtualbox/private_key IdentitiesOnly yes LogLevel FATAL
Important points for Windows Users:
Windows user should take a look at IdentityFile
in above output. They must use private_key
to connect to Virtual Machine using Putty tool.
Windows user will first convert private_key to public key using puttygen
, and then use putty or WinSCP
to connect to VM.
Windows user can also use vagrant ssh
, but for that they need to install openssh-client
on Windows machine.
Till now, you have setup Ubuntu virtual machine, and you are good to setup kops tool on it.
