October 09, 2025Move K8s Stateful Pods Between Nodes
Bret is joined by Philip Andrews and Dan Muret of Cast AI to discuss pod live migration between nodes in a Kubernetes cluster.
🙌 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. I'm thrilled to announce this course.

Cast AI dynamically moves your pod to a different node without downtime or data lost. It copies your running pod data, memory, IP address, and TCP connections from one node to another in real time.
In this episode, we nerd out over how Cast AI works under the hood, use cases for it, including hardware and OS maintenance on a node. I've got a feeling Cast AI has a winning feature on their hands.

We run through almost the entire Docker AI ecosystem, including the Model Runner for hosting open-source models locally or remotely, the Hub model catalog, Gordon AI chatbot integration within Docker Desktop and CLI, how MCP toolkit and catalog enable seamless tool integration with local AI systems, Docker's open-source MCP gateway for managing these connections, plus Docker's new Offload service for running containers and models entirely in Docker Cloud and much, much more!

July 29, 2025Could AI End Human QA?
Bret is joined by Andrew Tunall, the President and Chief Product Officer at Embrace, to discuss his prediction that we’ll all start shipping non-QA'd code (buggier code in production) and QA will need to be replaced with better observability.
🙌 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. I'm 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🍾

If AI causes us to ship more code, we’ll need more testing and QA. It’s unlikely that orgs will want to add staff just so they can use AI, so what’s the solution? Would we start relying more on production observability to detect code issues that affect user experience?
Embrace is a mobile observability platform company that I first met at KubeCon London this year. Their pitch was that mobile apps were ready for the full observability stack and that we now have SDKs to let mobile dev teams integrate with the same tools that we platform engineers and DevOps people and operators have been building and enjoying for years now. I wanted to hear from observability experts on how they think this is all going to shake out.

July 01, 2025AI Agents Running Containers
The Daytona founders - Ivan Burazin and Vedran Jukic - discuss their pivot to an AI agent cloud.
We dig into the new infrastructure requirements of developing agents that need their own sandboxes to operate in.
A year ago, we had them on to talk about Daytona giving us remote development environments for humans, and they have now pivoted the company to focusing on providing cloud hosting environments for AI agents to operate.
I suspect this is something we're all gonna eventually need to tackle as we work to automate more of our software engineering. So we spend time breaking down the concepts and the real world needs of humans developing agents, and then the needs of AI that require places to run their own tools in code.

April 21, 2025Docker Model Runner
Docker launched "Docker Model Runner" to run LLMs through llama.cpp with a single "docker model" command. In this episode Bret details examples and some useful use cases for using this way to run LLMs. He breaks down the internals. How it works, when you should use it or not use it; and, how to get started using Open WebUI for a private ChatGPT-like experience.
