DevNation Tech Talk: Getting GitOps

Modern day deployments can often resemble the chaos of navigating the high seas with poor visibility and the dangers of unexpected events. Dev and test environments, running test data sets and feature flags in the public cloud, and production being served from a self-managed site that securely hosts client data can all be a challenge without full observability and control. In this webinar, we show how you can reliably expand your Kubernetes footprint with Weave GitOps. Confidently observe and control your fleets, all from a single pane of glass across any environment. Join this webinar to learn how to: Control the health and propagation of customized clusters Easily assign and secure clusters across multiple teams for multiple purposes Observe all actions across all environments all from within Git Understand managing all deployments across your cluster and fleets

GitOps is a way of implementing continuous deployment for cloud native applications using Kubernetes. It focuses on a developer-centric experience by using tools like Git and continuous deployment that developers are already familiar with. GitOps uses Git as the single source of truth for infrastructure configuration and changes. It has four main principles: the system is described declaratively, Git is the single source of truth, changes can be automatically applied, and the system is continuously validated and improved. Common GitOps operators that facilitate continuous delivery include Flux, Argo CD, and Jenkins X. The GitOps model uses a pull-based deployment approach rather than pushing changes, improving security, observability, and productivity.

GitOps è un nuovo metodo di CD che utilizza Git come unica fonte di verità per le applicazioni e per l'infrastruttura (declarative infrastructure/infrastructure as code), fornendo sia il controllo delle revisioni che il controllo delle modifiche. In questo talk vedremo come implementare workflow di CI/CD Gitops basati su Kubernetes, dalla teoria alla pratica passando in rassegna i principali strumenti oggi a disposizione come ArgoCD, Flux (aka Gitops engine) e JenkinsX

This document discusses GitOps, an operational framework that uses version control and CI/CD practices to automate infrastructure provisioning. It defines GitOps as using a Git repository as the single source of truth for infrastructure definitions, with merge requests used to approve all infrastructure updates. These updates are then automated through continuous integration and delivery workflows. The document also introduces Argo CD as a GitOps tool that uses declarative specifications to accelerate application deployment and lifecycle management on Kubernetes through a pull-based model where the agent on the cluster pulls the desired application state from Git.

Looking ahead, many Ceph upstream projects are discussed that may be added to RHCS like erasure coding,

Modern cloud-native applications are incredibly complex systems. Keeping the systems healthy and meeting SLAs for our customers is crucial for long-term success. In this session, we will dive into the three pillars of observability - metrics, logs, tracing - the foundation of successful troubleshooting in distributed systems. You'll learn the gotchas and pitfalls of rolling out the OpenTelemetry stack on Kubernetes to effectively collect all your signals without worrying about a vendor lock in. Additionally we will replace parts of the Prometheus stack to scrape metrics with OpenTelemetry collector and operator.

GitHub plays a key role in the everyday work of thousands of developers and is a central piece of the open-source software ecosystem. Even though it is getting better and better every day, it still misses some key features that we need. If you want a better way of reviewing PRs, navigating through the code or better yet - writing the code without leaving the browser - this talk is for you! This talk will be demo driven, and as the title suggests, we will start with the aesthetic revamp. But we definitely won’t stop there! You will also learn a few cool things about interacting with GitHub through the command line. So not only your UI will be officially revamped, but you will also gain a productivity boost.

You will also learn how to deploy serverless applications (Quarkus) using a Knative service. Finally, KEDA will enable you to autoscale Knative Eventing components (KafkaSource) through events consumption over standard resources (CPU, memory).

Loom is among the most highly anticipated projects in the Java world. It promises to address concurrency and Java execution model issues by providing virtual threads. Thus, there is no need to write concurrent programs using asynchronous or reactive APIs; it will be possible to use the traditional imperative model and let Loom handle the rest. The JVM will execute the program and leverage non-blocking APIs automatically! Sounds good, doesn't it? How does it work, though? Are there any hidden costs? What is Loom going to change in modern Java frameworks? We will answer these questions in this talk. Starting with the integration of Loom in Quarkus, we will compare the different approaches we considered, discuss their respective pros and cons, and show how Loom might change the Java world.
