Hi ,
Configuring Kubernetes cluster is not that difficult for an experienced Dev-op , but still its more time consuming procedure when it comes to create a test lab environment. For newbies its even harder.
So , for this post lets discuss about Kubernetes vagrant setup.
Assuming that you are already familiar with Vagrant.
If not, refer Vagrant web .
Step1 . Install & Configure Vagrant
Download respective package from https://www.vagrantup.com/downloads.html .
For CentOS 7 & 8
# dnf install https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.rpm
For Debian & Ubuntu
# dpkg -i https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.deb
Check your installation,
# vagrant version
Installed Version: 2.2.6
Latest Version: 2.2.6
You’re running an up-to-date version of Vagrant!
Step2 . Setup K8s cluster
In this setup , we are using Virtual Box as hypervisor.
Ensure that Virtual Box is up and running.
Clone or download vagrant file and scripts from github repo.
# wget https://github.com/jamesarems/kubernetes-ubuntu/archive/1.0.1.tar.gz
# tar -xvf 1.0.1.tar.gz
# cd kubernetes-ubuntu-1.0.1
# vagrant up
It will take couple of minutes to configure your setup. Once its done, do
# vagrant ssh km1
Check your nodes with kubectl get no -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
km1 Ready master 2m v1.16.2 192.168.33.10 <none> Ubuntu 16.04.6 LTS 4.4.0-165-generic docker://18.9.0
ks1 Ready <none> 2m v1.16.2 192.168.33.11 <none> Ubuntu 16.04.6 LTS 4.4.0-166-generic docker://18.9.0
Cheers..! Our cluster is ready for testing.
If you need to add more resource like memory , cpu , additional node – Edit Vagrantfile.

This setup is very useful, if you are preparing for CKA (Certified Kubernetes Administrator).
