An automated, unattended script that creates on-premises Kubernetes 1.29 Clusters running on Ubuntu virtual machines using Vagrant.
What do you going to need?
- Vagrant https://www.vagrantup.com/docs/installation. Vagrant, developed by HashiCorp, is an open-source tool for creating and managing virtualized development environments. It allows users to easily configure and replicate development setups across different machines.
- VirtualBox https://www.virtualbox.org. VirtualBox is a free and open-source virtualization platform offered by Oracle.
- 4 Virtual Machines. One for the master node (3GB RAM, 1 vCPU), and three as workers (3GB RAM, 1 vCPU). All of them will be automatically provisioned via Vagrant, which is actually the partial scope of this article.
- An additional VirtualBox Host-Only Network. A Host-Only Network is a network configuration that allows communication between virtual machines and the host system but not with external networks. It provides a private network for isolated communication among virtual machines and the host. This can be useful for development and testing scenarios where you want to create a closed network environment.
Just execute the following script, and depending on your hardware you should expect a fully functionable Kubernetes 1.29 Cluster to be created in the next 10 minutes:
./setup.sh
