Kubernetes VCluster for "Clusters in Namespaces"

🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation in 2025. I'm so thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾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. Streamed live on YouTube on March 10, 2022.Unedited live recording of the complete show on YouTube (Ep #162).
