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.

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.

This episode is about what I'm seeing and what I'm doing right now, and then for the rest of the year. There are three parts. First, I talk about what's about to happen for me for the next few weeks re going to London for KubeCon. Then what I'm planning to change in this podcast, as well as my other content on YouTube for the rest of the year. And lastly, I talk about some industry trends that I'm seeing that will force me, I think, to change the format of this show. I recorded the episode on March 22, 2025.

The Docker Bake Build tool just went general availability, and I'm excited about what this means for creating reproducible builds and automation that can run anywhere. In this video I'm gonna break down some of the features, the benefits and walk through some examples.

In this episode I explain why docker buildx bake exists, what it can do, and I walk through multiple examples of Bake files and how it's better than docker build image and docker compose build. I also touch on BuildKit and Docker's GitHub Actions.
There's also a video version of this show on YouTube.

I've been a big fan of Swarm since it was launched over a decade ago and I've made multiple courses on it that still sell. But, we recently got some news out of Mirantis that might be bad news. So I talked about it last week on my live stream.
