Kubernetes makes it easier for businesses to automate software deployment and manage applications in the cloud at scale. However, if you’ve ever deployed a cloud native app, you know how difficult it can be to keep it healthy and predictable. DevOps teams and SREs often use distributed tracing to get the insights they need to learn about application health and performance.

2022 has been a year full of new releases, new events, and new projects for Open Source Calico. Let’s take a look at Project Calico’s 2022 highlights and see if you’ve missed any exciting news.

Over time, limitations were found with the programming languages responsible for creating web applications, leading to the development of WebAssembly (WASM). You can leverage WASM to create applications for web browsers using other high-level programming languages than those traditionally used for web development. As a result, developers can now build cloud-native applications that can work more efficiently with Kubernetes and other cloud-native technologies.

In the world of container orchestration, Kubernetes has become the de facto standard. Despite its simplicity in some respects, it has also introduced new levels of complexity in the deployment and management of distributed applications and services. To assist you with understanding the most common kubectl commands & plugins, we've created a cheat sheet as a reference for operations engineers, software engineers, and cloud infrastructure managers who use Kubernetes primarily.

Kubernetes monitoring can be difficult and complex. In order to determine the health of your project at every level, from the application to the operating system to the infrastructure, you need to monitor metrics in all the different layers and components — services, containers, pods, deployments, nodes, and clusters.

In this tutorial, we will walk through the setup of a single-node K3s Kubernetes cluster with Rancher, together with the S3 Gateway (s3gw) and a Longhorn PV (Persistent Volume). This guide will use Digital Ocean, but these instructions will likely work with other cloud providers as well.
