Demystifying Open-Source Orchestration of Unikernels With Unik

As the cloud-native ecosystem continues to evolve, many alternative solutions are popping-up, that challenges the status quo of application deployment methodologies. One of these solutions that is quickly gaining traction is Unikernels, which are executable images that can run natively on a hypervisor without the need for a separate operating system.

Five things to Log in your CI Pipeline: Continuous Delivery

Logs in continuous delivery pipelines are often entirely ignored, right up until something goes wrong. We usually find ourselves wishing we’d put some thought into our logs, once we’re in the midst of trawling through thousands of lines. In order to try to prevent this, we can add DevOps metrics into our logs, which will provide us with greater observability, and give insight into anything going wrong in our pipelines.

Upgrade a K3s Kubernetes Cluster with System Upgrade Controller

Kubernetes upgrades are always a tough undertaking when your clusters are running smoothly. Upgrades are necessary as every three months, Kubernetes releases a new version. If you do not upgrade your Kubernetes clusters, within a year, you can fall far behind. Rancher has always focused on solving problems, and they are at it again with a new open source project called System Upgrade Controller. In this tutorial, we will see how to upgrade a K3s Kubernetes cluster using System Upgrade Controller.

7-Step Cloud Transformation Roadmap

Before we can talk about the nuts and bolts of cloud transformation, it’s important to make the distinction from digital transformation. The two are often conflated, and while they are related, they are not the same—the cloud is the enabler of digital transformation. If you’re starting from scratch, cloud-native is the way to go.

Debug JavaScript in Google Chrome's Dev Tools in 7 easy steps

This article will focus on debugging JavaScript code within Google Chrome’s Developer Tools. Chrome’s Developer Tools are extremely powerful and will almost certainly speed up your troubleshooting process. We’ll be using Raygun Crash Reporting to find the stack trace and the line of code the error occurred on. You can sign up for a free 14-day trial here. So, let’s dive in!

Dynamic SSL Certificate Storage in HAProxy

Use the HAProxy Runtime API to update SSL certificates in HAProxy without a reload. When you route traffic through an HAProxy load balancer, you gain the ability to terminate SSL at the load balancer. HAProxy encrypts communication between the client and itself and then sends the decrypted messages to your backend servers, which means less CPU work on the servers because there’s no encryption work left to do.

Live Kubernetes Debugging with the Elastic Stack - Philipp Krenn (Elastic)

Your Kubernetes app is down. Your users start ranting on Twitter. Your boss is standing right behind you. What do you do? This talk walks you through a live debugging session without panicking: We are using the Elastic Stack in this demo with a special focus on its Kubernetes integration with metadata enrichment and autodiscovery in combination with APM / tracing, metrics, logs, and health checks.

DevOps Patterns and Antipatterns for Continuous Software Updates - Baruch Sadogursky (JFrog)

So, you want to update the software for your user, be it the nodes in your K8s cluster, a browser on user’s desktop, an app in user’s smartphone or even a user’s car. What can possibly go wrong? In this talk, we’ll analyze real-world software update fails and how multiple DevOps patterns, that fit a variety of scenarios, could have saved the developers. Manually making sure that everything works before sending an update and expecting the user to do acceptance tests before they update is most definitely not on the list of such patterns.
