    The hater's guide to Kubernetes, with Paul Butler

    If you're trying to make sense of when to use Kubernetes and when to avoid it, this episode offers a practical perspective based on real-world experience running production workloads. Paul Butler, founder of Jamsocket, discusses how to identify necessary vs unnecessary complexity in Kubernetes and explains how his team successfully runs production workloads by being selective about which features they use. You will learn: The three compelling reasons to use Kubernetes are managing multiple services across machines, defining infrastructure as code, and leveraging built-in redundancy. Why to be cautious with features like CRDs, StatefulSets, and Helm and how to evaluate if you really need them. How to stay on the "happy path" in Kubernetes by focusing on stable and simple resources like Deployments, Services, and ConfigMaps. When to consider alternatives like Google Cloud Run for simpler deployments that don't need the full complexity of Kubernetes Sponsor This episode is sponsored by Syntasso, the creators of Kratix, a framework for building composable internal developer platforms More info Find all the links and info for this episode here: https://kube.fm/kubernetes-hater-s-guide-paul Interested in sponsoring an episode?

You will learn: How the Kubernetes API processes requests through authentication, authorization, and Admission Controllers. The difference between Validating and Mutating webhooks and how to implement them using JSON Patch. Best practices for testing webhooks and avoiding common pitfalls that can break cluster deployments. Real-world examples of webhook implementations, including injecting secrets from HashiCorp Vault into containers.

    98% faster data imports in deployment previews, with Nick Nikitas

    Are you facing challenges with pre-production environments in Kubernetes? This KubeFM episode shows how to implement efficient deployment previews and solve data seeding bottlenecks. Nick Nikitas, Senior Platform Engineer at Blueground, shares how his team transformed their static pre-production environments into dynamic previews using ArgoCD Application Sets, Wave and Velero. He explains their journey from managing informal environment sharing between teams to implementing a scalable preview system that reduced environment creation time from 19 minutes to 25 seconds. You will learn: How to implement GitOps-based preview environments with Argo CD Application Sets and PR generators for automatic environment creation and cleanup. How to control cloud costs with TTL-based termination and FIFO queues to manage the number of active preview environments. How to optimize data seeding using Velero, AWS EBS snapshots, and Kubernetes PVC management to achieve near-instant environment creation.

    When Kubernetes and Go don't work well together, with Emin Laletović

    Discover how a seemingly simple 502 error in Kubernetes can uncover complex interactions between Go and containerized environments. Emin Laletović, a solution architect at Hybird Technologies, shares his experience debugging a production issue in which a specific API endpoint failed due to out-of-memory errors. He walks through the systematic investigation process, from initial log checks to uncovering the root cause in Go's memory management within Kubernetes. You will learn: How Go's garbage collector interacts with Kubernetes resource limits, potentially leading to unexpected OOMKilled errors. The importance of the GOMEMLIMIT environment variable in Go 1.19+ for managing memory usage in containerized environments. Debugging techniques for memory-related issues in Kubernetes, including GODEBUG for garbage collector tracing. Considerations for optimizing Go applications in Kubernetes, balancing performance and resource utilization.

    Declarative configuration and the Kubernetes Resource Model, with Brian Grant

    This episode offers a rare glimpse into the design decisions that shaped the world's most popular container orchestration platform. Brian Grant, CTO of ConfigHub and former tech lead on Google's Borg team discusses the Kubernetes Resource Model (KRM) and its profound impact on the Kubernetes ecosystem. He explains how KRM's resource-centric API patterns enable Kubernetes' flexibility and extensibility and influence the entire cloud native landscape. You will learn: How the Kubernetes API evolved from inconsistency to a uniform structure, enabling support for thousands of resource types. Why Kubernetes' self-describing resources and Server-side Apply simplify client implementations and configuration management. The evolution of Kubernetes configuration tools like Helm, Kustomize, and GitOps solutions. Current trends and future directions in Kubernetes configuration, including potential AI-driven enhancements.
