It describes Koreo's approach to Kubernetes configuration management and resource orchestration, and compares it with Helm and Kustomize, including their limitations for complex or dependent deployments. ### Source excerpt The platform engineering toolkit for Kubernetes Last month we open sourced Koreo, our "platform engineering toolkit for Kubernetes." Since then, we've seen a lot of interest from folks in the platform engineering and DevOps space. We've also gotten a lot of questions from people trying to better understand how Koreo fits into an already crowded landscape of Kubernetes tools. Koreo is a fairly complex tool, so it can be difficult to quickly grasp just what exactly it is_,_ what problems it's designed to solve, and how it compares to other, similar tools. In this post, I want to dive into these topics and also discuss the original motivation behind Koreo. ## Controller-Driven Infrastructure as Code DevFeed: [Controller-Driven Infrastructure as Code]() Original publisher: [Read original article]() Published: 2025-03-19T20:36:25Z Content type: article Language: en Sources: [Brave New Geek]() Topics: [Infrastructure as code](), [Kubernetes](), [consistency](), [Terraform](), [AWS CloudFormation](), [configuration](), [API]() Tags: [cloudformation](), [consistency](), [controllers](), [declarative](), [iac](), [infrastructure](), [infrastructure-as-code](), [koreo](), [kubernetes](), [platform-engineering](), [policy](), [reconciliation](), [resource-orchestration](), [terraform]() ### AI overview The article explains Controller-Driven Infrastructure as Code, applying Kubernetes controllers and the Kubernetes Resource Model to infrastructure management. It contrasts this resource-centric, continuously reconciled approach with the operation-centric models used by Terraform and CloudFormation. ### Source excerpt Harnessing the Kubernetes Resource Model for modern infrastructure management Infrastructure as Code (IaC) revolutionized how we manage infrastructure, enabling developers to define resources declaratively and automate their deployment. However, tools like Terraform and CloudFormation, despite their declarative configuration, rely on an operation-centric model, where resources are created or updated through one-shot commands. The evolution of IaC: From operations to controllers In contrast, Kubernetes introduced a new paradigm with its controller pattern and the Kubernetes Resource Model (KRM). This resource-centric approach to APIs redefines infrastructure management by focusing on desired state rather than discrete operations. Kubernetes controllers continuously monitor resources, ensuring they conform to their declarative configurations by performing actions to move the actual state closer to the desired state, much like a human operator would. This is known as a control loop. ## Spotlight on SIG Apps DevFeed: [Spotlight on SIG Apps]() Original publisher: [Read original article]() Author: The Kubernetes Authors Published: 2025-03-12T00:00:00Z Content type: article Language: en Sources: [Kubernetes Contributors Blog]() Topics: [Kubernetes](), [Development](), [Deployment](), [Command-line interface]() Tags: [applications](), [controllers](), [interview](), [kubernetes](), [spotlight]() ### AI overview An interview with the chairs and tech leads of Kubernetes SIG Apps about the group's mission, leadership, and work on developing, deploying, and operating applications on Kubernetes. The discussion also covers controllers and challenges from running AI-related workloads. ### Source excerpt In our ongoing SIG Spotlight series, we dive into the heart of the Kubernetes project by talking to the leaders of its various Special Interest Groups (SIGs). This time, we focus on SIG Apps , the group responsible for everything related to developing, deploying, and operating applications on Kubernetes. Sandipan Panda (DevZero ) had the opportunity to interview Maciej Szulik (Defense Unicorns ) and Janet Kuo (Google ), the chairs and tech leads of SIG Apps. They shared their experiences, challenges, and visions for the future of application management within the Kubernetes ecosystem. Introductions Sandipan: Hello, could you start by telling us a bit about yourself, your role, and your journey within the Kubernetes community that led to your current roles in SIG Apps? Maciej: Hey, my name is Maciej, and I'm one of the leads for SIG Apps. Aside from this role, you can also find me helping SIG CLI and also being one of the Steering Committee members. I've been contributing to Kubernetes since late 2014 in various areas, including controllers, apiserver, and kubectl. Janet: Certainly! I'm Janet, a Staff Software Engineer at Google, and I've been deeply involved with the Kubernetes project since its early days, even before the 1.0 launch in 2015. It's been an amazing journey! My current role within the Kubernetes community is one of the chairs and tech leads of SIG Apps. My journey with SIG Apps started organically. I started with building the Deployment API and adding rolling update functionalities. I naturally gravitated towards SIG Apps and became increasingly involved. Over time, I took on more responsibilities, culminating in my current leadership roles. About SIG Apps All following answers were jointly provided by Maciej and Janet. Sandipan: For those unfamiliar, could you provide an overview of SIG Apps' mission and objectives? What key problems does it aim to solve within the Kubernetes ecosystem? As described in our charter , we cover a broad area related to de ## VIPER Architecture for iOS Apps DevFeed: [VIPER Architecture for iOS Apps]() Original publisher: [Read original article]() Author: Surbhi Gupta Published: 2023-05-18T14:59:24Z Content type: tutorial Language: en Sources: [ymedialabs-innovation - Medium]() Topics: [iOS](), [Code](), [business logic](), [ui](), [navigation](), [mvc]() Tags: [apps](), [architecture](), [business-logic](), [code](), [controllers](), [flow](), [ios](), [modular](), [mvc](), [mvvm](), [navigation](), [patterns](), [swift](), [ui](), [viper]() ### AI overview This tutorial explains VIPER, an architectural pattern for iOS apps. It describes how VIPER divides each module into View, Presenter, Interactor, Entity, and Router components, with separate responsibilities and delegation-based communication. ### Source excerpt What is a Good Architecture? Architecture serves as a blueprint for a system. It provides a mechanism to communicate between various components and abstracts the complexity. It is important to separate out code components so that they are identifiable, serve a single purpose/responsibility and also fit logically. Code should be scalable, stable upon expansion, and flexible, which brings in the need for a good architecture. A good architecture not only helps in the success of the product but also allows for easy maintenance and makes people's lives easier. This article will talk about VIPER architecture, which is used to build many large projects. What is VIPER? VIPER is an architectural pattern like MVC and MVVM. One of the major issues with MVC and MVVM is bulky controllers. VIPER solves this problem by following Single Responsibility Principle and making the code more modular. Flow of Control Each module created with VIPER has five classes, each with their own responsibilities. No class does anything other than the specified role. These classes are listed below: View: It is responsible for only maintaining and displaying the view. It picks up any user interactions and passes the information to the presenter to decide the next step. Unlike other architecture patterns like MVC or MVVM, its sole responsibility is to manage and show the UI. Presenter: It is the only class that interacts with all other components except Entity. It is the decision-making engine for routing the flow. Interactor: It interacts with Entity and contains business logic. This class is where all the API calls and database interactions are added. Entity: Data model that is used by the interactor. Router: It does all the wire-framing or navigation from one module to another based on the information passed by the presenter. An ideal folder structure would be like below: Ideal Folder Structure with VIPER The communication between various components follows a delegation pattern. One component calls ## Fixing FactoryBot Validation Name Has Already Been Taken Controller Test or Spec Errors DevFeed: [Fixing FactoryBot Validation Name Has Already Been Taken Controller Test or Spec Errors]() Original publisher: [Read original article]() Author: Fuzzygroup Published: 2022-06-10T12:41:00Z Content type: tutorial Language: en Sources: [Scott Johnson]() Topics: [Rails](), [Testing](), [Ruby](), [Development]() Tags: [activerecord](), [bug](), [controllers](), [development](), [factorybot](), [rails](), [testing](), [tests]() ### AI overview This troubleshooting article examines recurring ActiveRecord "Name has already been taken" failures in FactoryBot-backed Rails controller tests. It describes investigating associations, test data, database cleaning, and model accessors while tracing the source of the validation behavior. ### Source excerpt So, last night, whilst pulling vampire hours on writing tests - always, always, always a bad idea - I encountered multiple variants on this bug: ❯ bundle exec rails test test/controllers/links_controller_test.rb:44 Running 7 tests in a single process (parallelization threshold is 50) Run options: --seed 21798 # Running: E Error: LinksControllerTest#test_should_get_edit: ActiveRecord::RecordInvalid: Validation failed: Name has already been taken test/controllers/links_controller_test.rb:47:in `block in ' This was particularly vexing because while the object in question did have a name attribute, it did not have name validations: ######################################################################### # # validations # ######################################################################### validates_presence_of :project_id validates_presence_of :team_id validates_presence_of :account_id validates_presence_of :link_type_id There are a number of people on the internet that have this issue including this stack overflow post. What I noticed as I researched this is that I only saw it in controller tests. Also my model tests continued to function correctly without any validation issues. I had initially discovered this while working on my RodAuth testing deep dive and back burnered it until I got past that particularly nasty kettle of fix. I was working with two objects, link and project and project only through an association. So my Factory for link looked like this: FactoryBot.define do factory :link do url { "https://www.example.com/?time=#{Time.now.to_i}" } name { "Cartazzi App on development #{Time.now.to_i}" } active { true } association :account association :team association :project association :link_type end end You will notice the insane use of Time.now.to_i to try and generate more distinct data. This was an attempt to see if maybe some kind of hidden validation was present (it is ruby and everything is dynamic; who knows where a monk ## Rails 7, Rodauth, BootRails, Nested Resources and Testing Controllers DevFeed: [Rails 7, Rodauth, BootRails, Nested Resources and Testing Controllers]() Original publisher: [Read original article]() Author: Fuzzygroup Published: 2022-06-10T08:12:00Z Content type: tutorial Language: en Sources: [Scott Johnson]() Topics: [Rails](), [Authentication](), [Testing](), [Security]() Tags: [account](), [authentication](), [controllers](), [framework](), [rails](), [rodauth](), [testing]() ### AI overview A Rails 7 development account describes using BootRails and RodAuth with nested account and link resources. The article explains authentication-aware routing and discusses adapting generated scaffolding and controller parameter handling for nested-resource testing. ### Source excerpt I'm working on a new project and, as I am front end challenged, I started by purchasing a copy of the BootRails framework as it seemed to have sensible defaults and an appearance that vastly outstrips my personal ability to manipulate Bootstrap. Previously I've worked with the JumpStart framework from Go Rails and while I love, love, love Chris Oliver, GoRails, HatchBox and everything Chris has done (yes I'm a super fan), I just can't get past JumpStart's use of Tailwind. BootRails makes a bunch of fairly opinionated decisions including the choice of RodAuth for authentication. They also use minitest and fixtures instead of rspec and FactoryBot. This blog post will cover how I figured out how to make testing work in a RodAuth environment for a nested resource. Note: It has literally been years since I've used nested resources but the application I'm developing is one where I particularly don't want security holes and nested resources nicely handle that. And, yes, I'm tipping my hat towards Sean Kennedy in Arkansas who taught me all about nested resources about a thousand years ago, way, way pre-pandemic. Unlike devise and everything else I've ever used in Rails, RodAuth has current_account instead of current_user. So you have an account object instead of a user object (I'm not saying it is wrong but it is different). For my application I have two resources: account link My routes file looks like this: constraints Rodauth::Rails.authenticated do resources :accounts do resources :links end end This means that my urls will look something like this: /account/23/link/99 i.e. you have to be logged in as account 23 to access link 99. Note: Writing the line above makes me realize that no other account can ever reference link 99 since the account is the parent object of the resource. The likely needed change is to nest these under the project object and then have a account_project model. But, as always, I digress. My first thing when I generated the links model was to scaffo ## Matter Security Model DevFeed: [Matter Security Model]() Original publisher: [Read original article]() Author: John Lee Published: 2022-02-24T00:00:00Z Content type: article Language: en Sources: [Blog on Developer Portal]() Topics: [Matter](), [Security](), [Cryptography](), [Protocol (disambiguation)]() Tags: [attestation](), [blog](), [certificates](), [controllers](), [cryptographic](), [cryptography](), [devices](), [esp32](), [infrastructure](), [integrity](), [iot](), [ledger](), [manufacturing](), [matter](), [privacy](), [process](), [protocol](), [public-key](), [security](), [storage](), [trust](), [verify]() ### AI overview An overview of Matter's security model, explaining how PKI, certificates, cryptography, and session establishment support trusted devices, trusted controllers, private communication, and data integrity.

It also discusses its benefits for rapid prototyping and quality, along with limitations such as no built-in factories or authorization. ### Source excerpt Wow. I am a damn idiot who has literally made his life harder than it ever needed to be -- for years. Sigh. I am referring to the Rails generator and the scaffold command. When you have complex software tools, sometimes you don't discover features - great damn features - for a long time. In this case I'm referring to: rails g scaffold pluralized_object_name In my case, I'm building a project where the ultimate goal is to create a label on something. Never mind what a label is or what the something is. A friend I've been helping with Rails recently asked me what rails g scaffold does and I muttered something about "makes the model and controller in one go" but I never thought to try it myself until just now. HOLY CRAP!

We also look at higher level abstractions such as Services, Controllers, and Deployments and how they can be used to ensure the desired state of an application deployed in Kubernetes
  • **Installing and Configuring Kubernetes** - In this module, we learn several ways to install a Kubernetes cluster. We start off simple with an installation using `kubeadm`. Then we head off to the Cloud, we look at the current state of the cloud managed Kubernetes services and installation methods for each of the maj ## Response: The Laws of Core Data DevFeed: [Response: The Laws of Core Data]() Original publisher: [Read original article]() Author: Marcus Zarra Published: 2018-05-10T21:39:50Z Content type: opinion Language: en Sources: [Cocoa Is My Girlfriend]() Topics: [Persistence](), [Concurrent Programming]() Tags: [asynchronous](), [controllers](), [core-data](), [data](), [main-thread](), [migrations](), [network](), [persistence](), [threads]() ### AI overview The author responds to another developer's proposed laws of Core Data, agreeing that Core Data should be treated as an object model rather than a database or thin SQLite wrapper. The article argues for encapsulating the persistence stack, using contexts only on their assigned queues, treating managed objects as data objects, and using parent-child contexts when working with external systems such as networks or imports and exports. ### Source excerpt Recently, I saw a post from Dave DeLong and knowing his history with the framework I read it with extreme curiosity. Unfortunately, that read led to this post as I disagree strongly with a number of the laws he has laid down. Since I know people are going to be asking me about this post [...] ## Testing MVC in Spring DevFeed: [Testing MVC in Spring]() Original publisher: [Read original article]() Published: 2018-01-30T00:00:00Z Content type: tutorial Language: en Sources: [Paweł Chudzik]() Topics: [Testing](), [Spring MVC](), [Spring Framework](), [REST API](), [Java]() Tags: [controllers](), [how-to](), [java](), [kotlin](), [rest-api](), [spring](), [testing]() ### AI overview A practical guide to testing Spring MVC applications, covering controller tests, separate MVC test groups, minimal test contexts, @WebMvcTest, and strict JSON verification. It also explains how API tests help preserve REST contracts and keep API documentation aligned with the build. ### Source excerpt Most of java web applications is built on top of the Spring Framework. Spring has pretty good support for testing and it is a mistake not to take advantage of features it offers. I've been developing various applications using Spring MVC for some time and I've noticed few patterns for testing that do work.

It compares a Converter implementation, PropertyEditor with @InitBinder, and @ControllerAdvice, while explaining why a Converter may not be discovered by @WebMvcTest. ### Source excerpt The story is really simple. I wanted to accept my class as rest controller method param. I decided that I don't want to convert a simple string to object every time and it would be faster if I do the conversion in the single place. After a quick research I've found Converter interface which looked like perfect for the job. After some digging and investigation it turns out that there is a lot of automagic in the Spring conversion service. Read more [Next page]()
