A few days ago, the Kubernetes community announced Kubernetes 1.14<\/a>, the most recent version of Kubernetes. Alongside it, Minikube, a part of the Kubernetes project, recently hit the 1.0 milestone<\/a>, which supports Kubernetes 1.14<\/a> by default.<\/em><\/p>\n

Kubernetes is a real winner (and a de facto standard) in the world of distributed Cloud Native computing. While it can handle up to 5000 nodes<\/a> in a single cluster, local deployment on a single machine (e.g. a laptop, a developer workstation, etc.) is an increasingly common scenario for using Kubernetes.<\/p>\n

A few weeks ago I ran a poll on Twitter asking the community to specify their preferred option for running Kubernetes locally on Linux:<\/p>\n

Ok, Twitter \u270b<\/p>\n

Your local Kubernetes cluster on Linux is deployed by:<\/p>\n

This is post #1 in a series about the local deployment options on Linux, and it will cover Minikube, the most popular community-built solution for running Kubernetes on a local machine.<\/p>\n

Minikube<\/a> is a cross-platform, community-driven Kubernetes<\/a> distribution, which is targeted to be used primarily in local environments. It deploys a single-node cluster, which is an excellent option for having a simple Kubernetes cluster up and running on localhost.<\/p>\n

Minikube is designed to be used as a virtual machine (VM), and the default VM runtime is VirtualBox<\/a>. At the same time, extensibility is one of the critical benefits of Minikube, so it’s possible to use it with drivers<\/a> outside of VirtualBox.<\/p>\n

By default, Minikube uses Virtualbox as a runtime for running the virtual machine. Virtualbox is a cross-platform solution, which can be used on a variety of operating systems, including GNU\/Linux, Windows, and macOS.<\/p>\n

At the same time, QEMU\/KVM is a Linux-native virtualization solution, which may offer benefits compared to Virtualbox. For example, it’s much easier to use KVM on a GNU\/Linux server, so you can run a single-node Minikube cluster not only on a Linux workstation or laptop with GUI, but also on a remote headless server.<\/p>\n

Unfortunately, Virtualbox and KVM can’t be used simultaneously, so if you are already running KVM workloads on a machine and want to run Minikube there as well, using the KVM minikube driver is the preferred way to go.<\/p>\n

In this guide, we’ll focus on running Minikube with the KVM driver on Ubuntu 18.04 (I am using a bare metal machine running on packet.com<\/a>.)<\/p>\n

Disclaimer<\/h2>\n

This is not an official guide to Minikube. You may find detailed information on running and using Minikube on it’s official webpage<\/a>, where different use cases, operating systems, environments, etc. are covered. Instead, the purpose of this guide is to provide clear and easy guidelines for running Minikube with KVM on Linux.<\/p>\n
