Automate K3s Cluster Installation on Flatcar Container Linux

In this tutorial, we install a highly available K3s cluster along with Flatcar Container Linux. K3s is a stripped-down Kubernetes distribution designed for edge computing deployments.

To complete this tutorial, you need to be familiar with the installation process of putting Flatcar Linux on remote bare metal servers. We extend the scenario to automate the installation of K3s along with the OS.

Leveraging Ignition to Configure K3s Installation

Let’s do a quick recap of the bare metal installation process of Flatcar Container Linux.

We take the help of two Ignition files to configure the OS. Ignition is a provisioning utility designed specifically for container OSs like Flatcar Container. The first file runs during the PXE boot installation process that ends by downloading and persisting the second Ignition file to the disk.

How To Install A Device Driver On Linux- 2 Methods › Servo Node

Itching your head due to missing device driver on your machine? Looking for how to install a device drive on a Linux system? Just switched to a new OS, but hardware is not working well? Check out this article to learn how you can install a missing device drive on your Linux system.

Installing and configuring a driver on a Linux based machine is quite daunting for those who just switched to Linux from Windows/Mac, or trying the new OS with dual boot. The widely used windows and Mac operating system often makes it a user-friendly experience when it comes to install device drivers, but in case of a Linux OS, the user might find some of their hardware is not working. Well, this would not be an issue anymore.

Is it challenging to install a device driver on Linux?
For Windows and Mac OS users, it’s really an easy approach to install any device driver as the OS detects those automatically. Also, the users can download the missing ones from the internet, and just click on a simple wizard to have the driver installed.

However, in case of a Linux platform, the process is not enough simple. One of the most common reason is, Linux is an open-source OS and a number of variations available. So, there can’t be a single method that can suit all Linux platforms, and every of the distribution has its own way regarding how to install a device driver on system.

In addition, most of the default Linux drivers are open-source and integrated in the system, and this makes the installation of missing drivers quite complicated, if not included already with OS. Still, most of the useful drivers are automatically detected with popular Linux distros.

Another reason why installing a device driver on a Linux can be complicated is license policies which technically vary among Linux distributions. Such as Fedora restricts to include drivers which are legally prohibited or violate cyber laws. Even Ubuntu asks its users to prevent using closed hardware.

Means, installing a device driver on a Linux can be a bit challenging, but still here mentioned 2 approaches can be helpful.

Two Methods To Find Drivers & Install on Linux
Approach 1: Using Built-in Interface
Approach 2: Using Command Line

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

(State of Kubernetes and Container Security, 2020)

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.
