Kubernetes Podcast from Google

Prodfiler is a new tool that provides fleet-wide full-system continuous profiling. It is in some ways the second act of its co-creator Thomas Dullien, who is an internationally-renowned reverse engineer and vulnerability researcher under the name Halvar Flake. Thomas joins us to discuss his career, what you should profile in a distributed system, and why you can’t sell something with a negative cost.

The most popular Ingress controller for Kubernetes is ingress-nginx, created in 2015 by Alejandro de Brito Fontes. Alejandro stepped down earlier this year, and the project is now maintained by a team including Ricardo Katz. Learn the history and what’s in the new 1.0 release from a pair of South American self-proclaimed sysadmins.

Adevinta is an online classified ads company, operating many local brands. Daniel Megyesi is a DevOps engineer at Adevinta and maintainer of their central big data and Machine Learning platform, Unicron. Learn why they wanted to replace Mesos, how they aligned their engineering efforts to do so, and the choices that had to be made to provide an easy experience for their data engineers.

KEDA, the Kubernetes Event-Driven Autoscaler, is a project that adds superpowers to the Kubernetes horizontal pod autoscaler, including zero-to-one scaling. Celebrate KEDA reaching Incubation in the CNCF by listening to an interview with maintainer Tom Kerkhove from Codit. But first, learn about Craig’s worst concert experience.

Kubernetes lets us manage our infrastructure declaratively, so why do we still manage the underlying OS with a myriad of different text files? And why allow shell and SSH access to a machine that should be immutable? So asked Andrew Rynhard before creating Talos, a Linux distribution built for Kubernetes. He’s now CTO of Talos Systems, a company founded to take it to market.

What is a telecommunications provider, if not a very distributed system? Kubernetes is becoming an important engine for the world’s telcos, especially as they roll out 5G. Vuk Gojnic leads the team rolling out Kubernetes across Deutsche Telekom (the parent company of T-Mobile), and he tells us how the worlds of telco and cloud have converged.

It’s Kubernetes release day! The team that launched v1.22 of everyone’s favourite cluster management software was led by Savitha Raghunathan, Senior Platform Engineer at MathWorks. Savitha joins host Craig Box to talk contribution, containers and cricket.

Sebastien Pahl is a pioneer of container technology, building the predecessor to Docker as a co-founder of Dotcloud. After working at some big tech companies, he’s back to the startup life as co-founder of Opstrace, a fully open source observability distribution, built on top of the tools you know and love.

The idea of software supply chain security rocketed into the public consciousness in the last year, with the news that US government agencies had been breached. Priya Wadhwa is a software engineer at Google working on open source security, including projects to secure and verify container deployments. She outlines what is being done to make sure this doesn’t happen to you.

Gatekeeper is an open source project which lets you enforce policy in a Kubernetes cluster. It’s also the basis for Policy Controller, a hosted and managed version now available for all GKE users. Max Smythe, a senior SWE at Google, is a maintainer of Gatekeeper and the TL of Policy Controller. He joins us to talk constraints, config and Cruise.

Debugging Kubernetes often involves correlating what happened just before something went bad. Itiel Shwartz is a co-founder of Komodor, a startup who builds a platform to help with exactly that. We talk Hebrew names, Hungarian dogs and German car crashes.

Steve McGhee worked as an SRE at Google for almost 10 years, then took a job outside the company. He was tasked with recreating “Google Production” and SRE practice from first principals, but with three books, modern cloud providers, and the entire Kubernetes ecosystem to help. How did he do? Learn about that which you can and can’t replace.

NVIDIA and Google have teamed up to bring the new Multi-Instance GPU feature, launched with the NVIDIA A100, to GKE. We speak to Kevin Klues from NVIDIA and Pradeep Venkatachalam from Google Cloud on how and why people use GPUs, optimising instance shapes for machine learning, and why less is often more.

Pixie Labs built an observabiity platform for Kubernetes, which uses eBPF to get telemetry without user intervention. They were recently acquired by New Relic, who open sourced the Pixie software. Co-founders Zain Asgar and Ishan Mukherjee join Craig Box to tell the story and talk about what’s next. Guest host Alex Ellis tends his garden.

A small army of community volunteers is necessary to host a KubeCon, but behind them is a professional events team. Colleen Mickey is Director of Event Services at the Linux Foundation and is responsible for KubeCon + CloudNativeCon, as well as other events like Hyperledger Global Forum and cdCon. She talks to us about hosting, feeding and watering 10,000 people, as well as the change to virtual events. We also bring the round-up of the KubeCon news, including our famous Lightning Round.
