This architectural setup is what we are going to achieve by end of this article Steps
The CIDR range provided to the NAT adapters ( 192.168.10.0/24) differs from the Home router Network ( 192.168.1.0/24), so there won’t be any conflict. Also, with NAT adapter, VM instances will access the external network, but no direct access to VM is possible. The NAT adapter, which will be assigned in a separate subnet, is how the Master and Worker node will communicate. With Bridge adapter, the VM will be in the same network as the router network, and it will enable me to ssh VM instance and no need to login to the console of these VM instances. These VM instances will have the OS of Ubuntu 20.4, and each of these VM instances will have two network interfaces, one Bridge adapter, and another NAT Adapter. We will be creating multi-cluster VM instances of one Master and worker node. In Mac, its Network → Advance → TCP/IP Tab as shown below You can check your router detail, by checking the Network settings in your system. My router network is configured at 192.168.1.0/24 VirtualBox and Ubuntu 20.04 Server Edition ISO image( Can be downloaded Free).Processor with VT-x Support (Virtualization Technology).System/Computer( Windows/ Mac/Linux) with minimum 8 GB of RAM, I am using in Mac, but the step is more or less similar for Windows or Linux.
This Tutorial was originally published in Medium blog What you Need In this tutorial, I will help you install 2 nodes Kubernetes cluster on your own computer so you don’t have to sign-up for AWS or Azure account, spin up computer servers and make it available when you need it.įollowing instructions will work out of the box on the latest Mac OS X however similar steps may work on any computer with virtualization software installed. This motivated me to build and configure a multi-cluster Kubernetes cluster in my local VM using a Virtual box with which I have full control.Īlthough you can find many tools, websites, and practice LABS where you can learn about Kubernetes, having your own cluster make it so easy and convenient compared to cloud-based tools. Ideally, Minikube is not suited when you want to learn and execute multi-cluster Use Case scenarios. Though it’s a great tool, Minikube runs a single-node Kubernetes cluster inside a VM. Typically Minikube is a utility that most developers use when they are learning Kubernetese.
