    TalosCon 2024

    We have 3 conversations from TalosCon 2024: 1. Vincent Behar & Louis Fradin from Ubisoft tell us how how they are building the next generation of game servers on Kubernetes. Recorded in a coffee shop. 2. We catch up with David Flanagan on the AI stack that he had success with in the context of rawkode.academy. David also tells us the full story behind his office burning down earlier this year. Recorded in the hallway track. 3. As for the last conversation, Gerhard finally gets together with Justin Garrison in person. They talked about TalosCon, some of the reasons behind users migrating off Cloud, and why Kubernetes & Talos hold a special place in their minds. Recorded in the workshop cinema room.

    Access your Kubernetes pods anywhere

    How does Michal Kuratczyk, Staff Software Engineer at RabbitMQ, access Kubernetes workloads securely, from anywhere? Regardless whether it's a Google Kubernetes Engine (GKE) cluster or Kubernetes in Docker (KiND), Tailscale is a simple solution for this particular use case. This also makes it easy to share private services with all devices on a tailnet, including with friends that want to access them on a smartphone.

  3. Modern CI/CD - Part 1

    Modern CI/CD - Part 1

    What does it look like to build a modern CI/CD pipeline from scratch in 2024? While many of you would pick GitHub Actions and be done with it, how do you run it locally? And what do you need to do to get caching to work? Tom Chauveau joins us to help Alex Sims build a modern CI/CD pipeline from scratch. We start with a Remix app, write the CI/CD pipeline in TypeScript and get it working locally. While we don't finish, this is a great start (according to Alex). This was recorded in January 2024, just as Dagger was preparing to launch Functions in the v0.10 release. While many things have improved in Dagger since then, the excitement & the joy of approaching CI/CD with this mindset have remained the same.

    80ms response SLO

    Alex Sims, Solutions Architect & Sr. Software Engineer at James and James Fulfilment, talks about their journey to 80ms response SLO with PHP & React. Alex shares how they optimised API performance, specifically highlighting improvements made by altering interactions with Amazon S3 and Redis. Key points include the transition from synchronous to asynchronous S3 processes, the impact of Amazon's SLO on write speed, and the significant runtime reduction achieved through JIT compilation in PHP 8.  We conclude with insights into decision-making in technology architecture, emphasising the balance between choosing cutting-edge technology and the existing skill set of the team. 🎬 View the video part of this episode at 80ms response SLO with PHP & React 🎁 Access the audio & video as a single conversation at makeitwork.gerhard.io EPISODE CHAPTERS (00:00) - Introduction (00:50) - 2023: A Year of Productive Chaos at James & James (02:43) - Alex's Journey throughout our Conversations (03:33) - What does James & James do?

  7. Automation Engine

    ١٩ شعبان

    Automation Engine

    Today we delve into BuildKit and Dagger, focusing on their significance in the development and deployment of containerized applications, as well as Kubernetes integration. BuildKit's Role: Essential for anyone using Docker Build, facilitating efficient, dependency-aware container builds with advanced caching mechanisms. It's not just for Docker but serves as a versatile execution engine across various projects, including Dagger.Eric's Attraction to BuildKit: The power of BuildKit's DAG (Directed Acyclic Graph) execution model and its parallelization and deduplication capabilities drew Eric to maintain and contribute to the project.First BuildKit Project: Eric's initial project, bincastle, aimed to build a development environment from source, highlighting BuildKit's ability to handle complex builds.Introduction of Dagger: Dagger builds on top of BuildKit, enhances automation by allowing developers to use familiar programming languages without being confined to a specific domain-specific language (DSL). It aims to simplify and optimize automation tasks, particularly in CI/CD environments.Dagger's Enhancements over BuildKit: Dagger introduces a language-agnostic layer, making automation more accessible and scalable. It incorporates features like remote caching and a services layer, potentially positioning it as a simpler alternative to Kubernetes for certain use cases.Future Directions: The podcast touches on ongoing developments, such as modules for sharing automation code within Dagger, aiming to foster an ecosystem where developers can easily reuse and contribute to collective automation solutions.The conversation highlights the evolving landscape of development tools, where BuildKit and Dagger play pivotal roles in making containerized development and deployment more efficient and user-friendly. Eric and Gerhard discuss the potential for these tools to simplify and enhance automation, reflecting on past projects and future possibilities. 🎬 View the video part of this episode: Deploying and Experimenting with Dagger 0.9 on Kubernetes 1.28 🎁 Access the audio & video as a single conversation at makeitwork.gerhard.io LINKS sipsma/bincastlemoby/buildkitdagger/daggerdagger --mod github.com/sipsma/daggerverse/yamlinvaders@8071646e5831d7c93ebcd8cca46444250bf25b8c shell play EPISODE CHAPTERS (00:00) - Intro (01:43) - What attracted you to BuildKit?

  8. How much CPU & Memory?

    ١٩ شعبان

    How much CPU & Memory?

    This episode looks into the observability tool Parca & Polar Signals Cloud with Frederic Branczyk and Thor Hansen. We discuss experiences and discoveries using Parca for detailed system-wide performance analysis, which transcends programming languages. We highlight a significant discovery related to kube-prometheus and the unnecessary CPU usage caused by Prometheus exporter's attempts to access BTRFS stats, leading to a beneficial configuration change for Kubernetes users globally. We also explore Parca Agent's installation on Kubernetes 1.28 running on Talos 1.5, the process of capturing memory profiles with Parca, and the efficiency of the Parca Agent in terms of memory and CPU usage. We  touch upon the continuous operation of the Parca Agent, the importance of profiling for debugging and optimization, and the potential of profile-guided optimizations in Go 1.22 for enhancing software efficiency. 🎬 Screensharing videos that go with this episode: First impressions: Parca Agent on K8s 1.28 running as Talos 1.5See where your Go code allocates memoryHow to debug a memory issue with Parca?See which line of your Go code allocates the most memory🎁 Access the audio & all videos as a single conversation at makeitwork.gerhard.io LINKS Go Profile-guided optimizationView Profiling Data within CodeAnnouncing Continuous Memory Profiling for RustEPISODE CHAPTERS (00:00) - Intro (02:21) - kube-prometheus discovery & fix (06:29) - Parca Agent on K8s 1.28 running as Talos 1.5 (06:49) - How to capture memory profiles with Parca?
