#88 Kubernetes on a Tractor: Precision Farming with K3s and Edge AI 31:21

cách đây 4 ngày trước31:21

31:21

Recorded at the Dutch Cloud Native Day, hosts Ronald Kers (CNCF Ambassador) and Jan Stomphorst (Solutions Architect at ACC ICT) dive into one of the most original edge computing use cases we’ve seen so far—running a full Kubernetes environment from the top of a tractor. They speak with Wieneke Keller, CTO at Aurea Imaging, and Sebastian Lenartowicz, Senior Software Engineer on the TreeScout project, about how Kubernetes—specifically K3s—is transforming apple and pear orchards across Europe. 🚜 From Monolith to Microservices… on a Tractor Aurea Imaging’s TreeScout system mounts on tractors and uses cameras, deep learning models, and high-precision GPS to scan individual trees in real time. The goal: optimize every tree’s yield by targeting only the trees that need treatment—such as blossom thinning—rather than spraying entire fields. This leads to better-sized apples and reduced waste, with significant environmental and economic benefits. In 2023, their first field trials struggled with reliability and maintainability. A monolithic Python application in a single Docker container was hard to debug, and even small errors had major impact. Only 6 out of 40 test runs were successful. That’s when the team decided to introduce Kubernetes at the edge. 🧠 Why Kubernetes (K3s)? With limited power and compute available on the tractor, they chose K3s, a lightweight Kubernetes distribution perfect for single-node setups. Each tractor runs a ruggedized NVIDIA Jetson, hosting microservices for computer vision, data processing, and communication. The services interact via RabbitMQ, and deployment is managed via Argo CD with OCM (Open Cluster Management), allowing over-the-air updates even on flaky 4G connections. This setup significantly improved resilience and observability—when a critical bug appeared during a large-scale rollout in Italy, the team could diagnose and fix it within 4 hours and redeploy remotely. 🌱 Scalable, Sustainable, and Smart TreeScout is currently in use with 25 customers and expanding internationally. Future plans include yield prediction, time series insights per tree, and even integration into smart sprayers that dynamically adjust treatment as the tractor moves. The team discusses Kubernetes not just as a technology choice but as an enabler for sustainable, scalable agriculture. They also reflect on the broader trend of Kubernetes moving to the far edge, and how tools like K3s, Kairos, and batteries-included Kubernetes distros will be key for the future. 🌍 Final Thought: Tech with Impact Wieneke and Sebastian share how working at the intersection of data, hardware, and sustainability is incredibly rewarding. TreeScout not only empowers farmers—it also shows how Kubernetes can contribute to a better, more precise and environmentally conscious future. Stuur ons een bericht.

#87 Beyond Containers: WebAssembly in Kubernetes 35:52

cách đây 11 ngày trước35:52

35:52

📍 Recorded during SRE Day in Amsterdam In this episode of the Dutch Kubernetes Podcast, Ronald Kers (CNCF Ambassador) and Jan Stomphorst (Solutions Architect at ACC ICT) sit down with Deepu K Sasidharan (Co-chair of JHipster ) to explore a groundbreaking topic: running Kubernetes without traditional containers using WebAssembly (Wasm). 🔹 What is WebAssembly, and why should you care? Originally designed for running high-performance applications in web browsers, WebAssembly is now making its way into cloud-native computing and Kubernetes environments. Deepu explains how WebAssembly differs from containers and why it could be a game-changer for serverless computing and edge workloads. 🔹 Why WebAssembly in Kubernetes? ✅ Faster startup times – Near-instant execution compared to container cold starts. ✅ Lightweight execution – No OS dependencies, making it more efficient. ✅ Better security & isolation – Sandboxed execution with minimal attack surface. ✅ True serverless? – Potential for workloads that truly start and stop instantly. 🔹 Challenges & Limitations 🔸 Not every application can be easily ported – Multi-threading and TLS support are still evolving. 🔸 Standardization is still in progress – Different WebAssembly runtimes (e.g., WASI, Spin, WasmEdge) implement features differently. 🔸 Limited ecosystem adoption – Kubernetes and cloud providers are still building support for WebAssembly workloads. 🔮 What’s Next? As WebAssembly adoption grows, could it replace containers for certain workloads? Major cloud providers, Kubernetes distributions, and companies like Docker are investing in Wasm, but there’s still a long way to go before it becomes a mainstream alternative. 🚀 Is WebAssembly the next big thing in cloud-native computing, or just another niche technology?

#76 Kubernetes at the Edge? Think Again 55:32

cách đây 13 weeks trước55:32

55:32

In this episode of the Nederlandse Kubernetes Podcast , hosts Ronald Kers (CNCF Ambassador) and Jan Stomphorst (Senior Solutions Architect bij ACC ICT) sit down with Carl Moberg , an expert in network automation and co-founder of an innovative edge orchestration platform. Carl shares his extensive experience in automation and orchestration, highlighting why Kubernetes, despite its strengths, is not always the best solution for edge computing. Carl describes how edge computing environments, such as retail stores, manufacturing plants, and mining operations, face unique challenges. Unlike the cloud, edge deployments require systems that are lightweight , resilient , and able to operate offline . These environments often run on constrained hardware with little room for the complexity that Kubernetes introduces. Why Kubernetes Isn’t Always the Right Choice Carl explains that while Kubernetes excels in the cloud, it struggles at the edge due to: Resource Constraints: Kubernetes assumes ample compute, memory, and network resources, which edge locations lack. Operational Overhead: Supporting components like registries, policy engines, and logging tools make Kubernetes impractical across thousands of edge nodes. Resilience Needs: At the edge, workloads must run uninterrupted, even when internet connectivity is lost—something Kubernetes’ centralized architecture complicates. Instead of Kubernetes, Carl and his team developed a 150MB lightweight agent that runs on Docker or Podman. This solution provides core features like: Dynamic Application Placement: Applications are deployed based on criteria like hardware capabilities (e.g., GPUs), location, or attached devices (e.g., cameras). Resilient Offline Operations: Local registries, automated updates, and failover mechanisms ensure continuity during outages. Simplified Management: By abstracting orchestration complexity, the platform avoids Kubernetes’ resource and setup overhead.
