Join the Guild and become your team's leader in AI for infrastructure automation https://www.bretfisher.com/theguild 🍾Bret is joined by Anca Iordache and Dave Scott, software engineers at Docker Inc, to talk about why they made Docker Desktop for Linux and how it's different from running the Docker Engine daemon. Streamed live on YouTube on 21 April 2022.Unedited live recording of the complete show on YouTube (Ep #167). Includes demos.We talk about the origins of Docker Desktop for Linux, why it needs to exist, and how it's different than  running Docker Engine on the native host. Docker Desktop for Linux behaves like Mac and windows versions where it uses a VM and we clear up some confusion around that. Further, we talk about some of the functionality with operating it in tandem with Docker Engine on the host so you can run both at the same time and use context to switch between them. ★ Topics ★Download Docker Desktop for LinuxDocker RoadmapDocker Desktop for Linux GitHub IssuesDocker Developer Preview ProgramDocker Community SignupDockerCon 2022★ Join My Community ★Best coupons for my Docker and Kubernetes coursesChat with us on our Discord Server Vital DevOpsHomepage bretfisher.com (00:00) - DDT MAIN (00:04) - Show intro (00:53) - Bret intro (01:56) - Main show (02:14) - About Dave (03:15) - About Anca (04:45) - Compose is her favorite (06:16) - Why does Docker Desktop exist?

Meetups are happening now, with new course videos dropping every few weeks. Join the Guild and become your team's leader in AI for infrastructure automation https://www.bretfisher.com/theguild 🍾Bret is joined by Lukas Gentele and Rich Burroughs of Loft Labs to talk about vcluster, a Kubernetes distribution that can run inside an existing cluster namespace, aka "clusters in clusters." Lukas is the CEO of Loft Labs and Rich is their Senior Developer Advocate. VCluster is quite a universal tool for running fully-fledged Kubernetes clusters for dev and test environments and even potentially in production. In this episode, Lukas and Rich break down a ton of ways vcluster is currently being used and where they see it going in the future.

Jim is the CEO and co-founder of Nirmata. He's also the founder of Kyverno, an CNCF Sandbox Project and open source project for managing policies in Kubernetes. We talk about what Kyverno is, what it isn't, and what problems it solves. We also talk a bit about Narmada and how it expands on that.If you're in a team using Kubernetes together, controlling settings and standards in your workloads and clusters can be a constant source of frustration unless you have something to govern those policies across all your workloads and clusters.Streamed live on YouTube on Feb 24, 2022.Unedited live recording of the complete show on YouTube (Ep #160). Includes demos.★Topics ★Kyverno is a policy engine designed for Kubernetes. With Kyverno, policies are managed as Kubernetes resources, and no new language is required to write policies. This allows using familiar tools such as kubectl, git, and kustomize to manage policies. Kyverno policies can validate, mutate, and generate Kubernetes resources plus ensure OCI image supply chain security. The Kyverno CLI can be used to test policies and validate resources as part of a CI/CD pipeline.Nirmata "Intelligent Guardrails for Kubernetes."
