Using S3 as Local Storage on kubernetes with S3 CSI Driver

Originally posted on the Israeli Tech Radar on medium.

TLDR; In the world of cloud-native applications, efficient and scalable storage solutions are crucial. Amazon S3 (Simple Storage Service) is a popular object storage service, but what if you could use it as local storage in your Kubernetes clusters? Enter the S3 CSI (Container Storage Interface) Driver, a game-changer for developers and operations teams alike.

Building a Developer Platform: “Behind the Scenes” of application lifecycle management

Originally posted on the Israeli Tech Radar on medium.

In the dynamic realm of software development, particularly within agile and cloud-native landscapes, the ability to swiftly adapt and innovate is paramount. This agility, however, often comes with its own set of challenges, especially when it involves the coordination and management of numerous microservices and processes. Herein lies the crux of our narrative: the establishment of a robust developer platform, metaphorically dubbed “The Show” for its ability to seamlessly present the final act to the audience — our customers — without exposing the countless hours and effort invested backstage by developers and operations personnel.

TLDR; This is a quick share of a neat tool which found it’s way into my toolset, it did it in such a significant way which enabled me to combine tools in a common way — something I’ve been missing for quite a while. This is also a thank you to the author’s and contributors of go-task which is such an awesome tool.

Kubernetes Control Loops: The Secret Sauce Behind Your Microservice Bliss

Originally posted on the Israeli Tech Radar on medium.

TLDR; Ever dreamt of a system that manages your microservices like a maestro, constantly keeping them in perfect harmony? Kubernetes makes this a reality with control loops, the magic behind the scenes. Operators take it a step further, letting you customize Kubernetes for even more control over custom workload needs.

Background on why I’m writing this series

Part of my role at Tikal requires me to interview candidates for DevOps / SRE / Platform Engineers, nowadays in the center of any modern application we have kubernetes and considering kubernetes has many extensions in the form of controllers and operators, one of the questions I like asking is — give me an example of 5 controllers or operators you used / will use when setting up a new kubernetes cluster, this post will attempt to answer that question as much as possible tackling the core challenges we meet when setting up and running an application on kubernetes.

Planning a production ready kubernetes with fundamental Controllers & Operators — Part 3 — DNS & Service discovery

Originally posted on the Israeli Tech Radar on medium.

As we continue to build our production grade cluster, we should explore the central components of Kubernetes, one of it’s core features is service discovery which is achieved by using DNS, this sub-system is fundamental for understanding how applications communicate with one other, and are how they are made accessible externally. This part of the series will start by diving into the internal mechanisms of service discovery, and then expand on how Kubernetes integrates with external DNS systems for service accessibility which will also prepare us for part 4 which will discuss ingress traffic.ֿ

Welcome back to part four of our series on building a production-ready Kubernetes cluster with fundamental controllers and operators! In the previous parts, we explored essential components like Secrets and DNS management. Today, we’ll delve into the world of Ingress, a critical concept for routing external traffic to your applications within the cluster. To explain Ingress, I’ll be taking the Analogy approach, I’ll use the analogy of a city compared to a modern distributed computer:

TLDR; Just when we thought we’ve got it figured out! We learn there’s a better, faster way of doing things, frameworks, abstractions, and methodologies invented to make our development experience easier, and help us during our journey to building a platform. But…Do we really need one?/Should we adopt one? What impact will that have on our product? The following post will try to tackle some of these questions as we explore building a better Developer Experience.
