Dive into the world of K Configuration Language (KCL). This review and walkthrough illuminates the features and advantages of using KCL to generate YAML or JSON configurations and manifests. We cover the basics of KCL’s syntax, its approach to handling hierarchical data, and demonstrate how to define and manipulate configurations with clarity and precision.
Continue readingEmbark on a journey to Kubernetes excellence with a dive into Kubernetes Workloads APIs. This video is your one-stop shop for mastering the various controllers and APIs that define how applications run on the powerful orchestration platform.
We kick off with the building blocks of all Kubernetes workloads – Pods. You’ll learn about their lifecycle, how to create them, and what makes them tick. But since Pods alone aren’t enough for a robust system, we introduce ReplicaSets – the key to ensuring your desired number of pod replicas are always up and running.
Next, we level up to Deployments for complete lifecycle management of your Pods and ReplicaSets, including updates and rollbacks. You’ll gain insights into setting up zero-downtime deployment strategies that keep your applications resilient.
For applications that require stable networking and persistent storage, we dive into StatefulSets, explaining how they differ from Deployments and suit specific use cases. You’ll learn how to handle stateful applications with confidence, ensuring data consistency and service discovery.
DaemonSets ensure that some workloads are a constant presence on your nodes. We cover scenarios where DaemonSets are essential and show you how to utilize them for tasks such as log collection and monitoring.
For workloads that need to run once or periodically, we unpack Jobs and CronJobs. Discover how to define batch jobs that run to completion and schedule them to run automatically, so your applications can handle maintenance tasks, data processing, or any other work that doesn’t fit into the always-on service model.
By the end of this video, you’ll possess an understanding of Kubernetes Workloads APIs. You’ll not only be able to deploy various types of applications but also manage their lifecycle and scale with the demands of your users.

In this tutorial, we focus on ensuring your Kubernetes deployments, services, and entire cluster configurations stand up to the highest standards of quality and reliability.
Get ready for a review and hands-on walkthrough on utilizing Kyverno Chainsaw to test your Kubernetes resources.
Continue readingSimplify your development game with Devbox acting as a simplification layer on top of Nix. Use it to install all the tools required to work on a project and create ephemeral environments that can run as local Shells, remotely as DevContains for GitHub CodeSpaces or DevPod, in Docker containers, or in CI/CD pipelines.
Continue readingIn this fifth installment of our Crossplane tutorial series, we are exploring Composition Functions. They allow us infinite flexibility to define which Managed Resources to create, manage, and delete, and how to do that.
Continue readingExplore the world of data serialization formats as we delve into the question, Is PKL the Ultimate Data Format? In this video, we embark on a journey to discover the strengths and weaknesses of Apple Pkl. We put it up against popular contenders like YAML, JSON, CUE, and others, to assess its usefulness.
Continue readingIn this fourth installment of our Crossplane tutorial series, we are exploring Configuration Packages. They allow us to package Crossplane Compositions as OCI (Docker) images and distribute them to control plane clusters.
Continue readingWe dive into the powerful synergy between External Secrets Operator (ESO) and Crossplane to efficiently manage and propagate secrets across your Kubernetes clusters, databases, and secrets managers. Learn how to securely and seamlessly integrate with cloud providers’ secret management systems using ESO, and see how to leverage Crossplane’s infrastructure as code capabilities to ensure your secrets are consistently deployed wherever they’re needed.
Continue readingIn this third installment of our Crossplane tutorial series, we are exploring Compositions, probably the most important feature in Crossplane. They allow us to define interfaces (CRDs) and controllers that represent services we can use to enable others to manage resources like databases, clusters, applications, or anything else.
Continue readingWe dive deep into the world of developer platform consoles, exploring the importance of simplicity, API-based architectures, and the crucial role these elements play in discoverability, operations, and observability. We argue that developer platform consoles should aim for a ‘dumb’ design philosophy – one that emphasizes straightforward interfaces and leverages APIs to interact with underlying services and data. By stripping down the complexity traditionally found in these consoles, developers can achieve greater efficiency and enhance the maintainability of their systems.
