Learn Kubernetes Weekly issue 124

Mercado Libre, From Autopilot to Standard GKE, Dynamic Kubernetes API Server, ArgoCD got beaten by FTP, Observability strategies

26 Mar 2025

KubeFM published a book of battle-tested experiences from engineers who pushed Kubernetes to its limits and lived to tell the tale. Download for free here.

  1. Kubernetes at Mercado Libre

    Juliano Marcos Martins

    Learn how Mercado Libre adopted Kubernetes to manage 30,000 microservices and support 16,000 developers, streamlining infrastructure and improving cost efficiency.

  2. From Autopilot to Standard GKE: The Key to 15x Cheaper Istio

    Yurii Serhiichuk

    Discover how switching from GKE Autopilot to GKE Standard & Istio Ambient mode can reduce costs by 15x, from $3065/month to $185/month for 10 nodes.

  3. How We Built a Dynamic Kubernetes API Server for the API Aggregation Layer in Cozystack

    Learn how the Kubernetes API aggregation enables dynamic resource management by creating custom API servers that extend platform capabilities, solving complex API interaction challenges without traditional CRD limitations.

  4. All my DevOps pipelines from GitLab commit to ArgoCD got beaten by FTP

    David Pech

    In this case study, you will learn how a pipeline from GitLab to ArgoCD was outperformed by FTP uploads, highlighting the importance of team readiness and customer needs before adopting new tech like Docker and containerization.

  5. Examining approaches and patterns for debuggability: ephemeral containers and Argo Workflows

    Anusha Ragunathan

    In this article, you'll explore the journey behind building a "Debuggability Paved Road" at Intuit — a concept that defines a common set of standardized tools, practices, and processes to streamline development workflows.

  6. Observability strategies to efficiently scale Kubernetes pods

    Jay

    The article advocates using eBPF and tools like Cilium & Hubble to efficiently scale Kubernetes pods via granular observability, enabling dynamic scaling, auto-throttling, and latency optimizations, reducing resource waste and improving efficiency.
