Kubernetes 1.16 is out, and our guest this week is its release manager, Lachlan Evenson. Lachie is a Principal Program Manager at Microsoft and an Australian living in the US; Craig and Adam are therefore method-interviewing, being this week in those two countries respectively.
containerd was born from community desire for a core, standalone runtime to act as a piece of plumbing that applications like Kubernetes could use. It sits between command line tools like Docker, which it was spun out from, and lower-level runtimes like runC or gVisor, which execute the container’s code. This week’s guest is Derek McGowan, a Software Engineer at Docker and a containerd maintainer-d.
Along with the news of the week, Adam and Craig discuss the many Vancouvers.
Patrick Lang is the co-chair of the Kubernetes Windows SIG. He is a Senior Software Engineer at Microsoft, developing Kubernetes and related open-source projects supporting Windows Server Containers. Patrick joins Adam and Craig to tell the story of how containers came to Windows.
kind stands for Kubernetes in Docker. Originally built for continuous integration (CI) and testing of Kubernetes itself, kind has found many uses, including acting as a cluster for bootstrapping other clusters. Original author Ben Elder from Google Cloud joins Craig and Adam to talk about it.
Container Camp is a series of independent conferences, spanning three continents and in their fifth year. “Camp mother” Angie Maguire is the co-organiser, and is also the founder of Ladies of Code. She joins Adam, who is yet to attend a camp, but actually goes camping, and Craig, who has spoken at events in London and Sydney, and prefers hotels.
Kubernetes and Docker might not seem the obvious choice for managing virtual macOS instances on hosted Apple hardware. Learn how they were used to build Orka - Orchestration for Kubernetes on Apple - a virtualisation layer for Mac build infrastructure offered by hosting company MacStadium. Craig and Adam ask MacStadium SVP of Software Chris Chapman about Orka, and how Kubernetes is useful in places you might not expect.
No matter how you say it, you probably use kubectl all the time. Did you know you can extend it with plugins? Did you know you can find and install those plugins using krew, a plugin manager for kubectl? krew was built by Luk Burchard, a student at TUBerlin, as an intern project. He was supervised by Ahmet Alp Balkan at Google Cloud, and they both join Craig and Adam to discuss it.

All three join Adam and Craig for a short physics lesson and a view into computing at the largest scale, for particles at the smallest.
The Cloud Native Application Bundle is a spec for packaging distributed apps, developed by Microsoft with support from Docker and Pivotal. Jeremy Rickard, a senior software engineer at Microsoft Azure, and Ralph Squillace, principal PM for open source/developer user experience at Microsoft Azure, join Craig and Adam to discuss it.
Mark Shuttleworth is the founder of Ubuntu and CEO of its parent company Canonical. Ubuntu is the Linux distribution of the Cloud. You can use it inside your containers, or you can use it as your node OS. Canonical packages Kubernetes for both the edge (MicroK8s) and the server (Charmed Kubernetes). Oh, and aside from that, Mark was the first African in space, spending 8 days on the International Space Station in 2002. Craig and Adam ask Mark about how this all happened, and how it has changed his perspective on technology.
Banzai Cloud is a cloud-native software company that builds Pipeline, a managed Cloud Native application and devops platform, featuring tools for managing multi- and hybrid-cloud Kubernetes deployments.

John Murray, a product manager at Google Cloud, joins Craig and Adam to talk about policy and configuration, and introduce the new CSP Config Management tool launched to Beta along with the new Cloud Services Platform.
The history of Borg influences the history of Kubernetes in many ways: Google has different teams handle “get traffic to a cluster” and “serve traffic”, so Kubernetes has a conceptual split here too. Tim Hockin, Kubernetes co-founder, Google principal engineer and former Borg/Omega team leader, joins Adam and Craig to explain the history and future of the Ingress API, why it’s taken so long to get to v1, and how it might evolve in the future.
