This setup is used to create kubernetes cluster on local laptop / desktop using vagrant - with this we can create a two node cluster setup which contains one master and one worker node with one single command.

• Git
• Vagrant
• Oracle Virtual Manger
• Virtualization needes to be enabled in System BIOS
• Minimum laptop/desktop configuration - 32GB RAM / 8CPU (not to worry base OS will balance the cpu need on time sharing model), 80GB hdd disk space

• Open bash terminal
• Checkout the code (git clone https://github.com/SubhakarKotta/k8s-vagrant-centos.git)
• $ cd k8s-vagrant-centos/provisioning

Default settings:Vagrantfile

VM:
  password: kubeadmin
  master:
    ip: 100.10.10.100
    cpus: 2
    memory: 2048
    vmname: kmaster
    hostname: kmaster.example.com
  worker1:
    ip: 100.10.10.101
    cpus: 3
    memory: 16384
    vmname: kworker1
    hostname: kworker1.example.com

By running the below command kubernetes cluster will be created with 2 Centos VM's installed.

• vagrant up

helm / kubernetes-dashboard / nfs-volume-provisioner

By default below are the IP Addresses that will be configured for the VM's

The Kubernetes Dashboard can be accessed via the below URL without any changes from your host machine

http://100.10.10.100:30070/#!/overview?namespace=_all

The Vagrant VM can be accessed in two ways

1. Login through vagrant ssh

• $ cd k8s-vagrant-centos/provisioning
• $ vagrant ssh kmaster
• $ vagrant ssh kworker1

2. Login through putty

• 100.10.10.100 / 100.10.10.101 [Username/Password:vagrant/vagrant (OR) root/kubeadmin]

• $ cd k8s-vagrant-centos/provisioning
• $ vagrant halt

• $ cd k8s-vagrant-centos/provisioning
• $ vagrant up

• $ cd k8s-vagrant-centos/provisioning
• $ vagrant destroy
