How to configure kubernetes Version 1.28.1 lab using vagrant and ansible playbook
I am providing you here easy steps to create a lab for kubernetes, which will help in self learning
Pre-requiste:
- You need to download and install vagrant software from link: https://developer.hashicorp.com/vagrant/downloads
- Install oracle virutal machine from link: https://www.oracle.com/in/virtualization/technologies/vm/downloads/virtualbox-downloads.html
You can use below vagrant file to create centos8stream vagrant virtual machine.
Note:
Below configuration has 8GB RAM and 2 Core CPU, if needed you can still downgrade your configuration if required.
Your laptop should have atleast 16GB RAM and 4 Core CPU, if you are using below vagrant file without any changes.
Ensure to place below files same folder whether vagrant file is stored.
10-kubeadm.conf
bootstrap.sh
k8s-v1.28.playbook
k8s-v1.28-install.playbook
Finally your kubernetes Lab Setup is completed.
