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.

Or watch the video version on YouTube. Bret is joined by Willem Delbare and Roeland Delrue to discuss Aikido, a security tool consolidation platform designed specifically for smaller teams and solo DevOps practitioners.
The discussion explores how Aikido addresses the growing challenges of software supply chain security by bringing together various security tools - from CVE scanning to cloud API analysis - under a single, manageable portal. Unlike enterprise-focused solutions, Aikido targets the needs of smaller teams and individual DevOps engineers who often juggle multiple responsibilities. During the episode, they demonstrate Aikido's capabilities using Bret's sample GitHub organization, and show how teams can implement comprehensive security measures without managing multiple separate tools.

Bret is joined by Mumshad Mannambeth and Vijin Palazhi of KodeKloud for Q&A on what we should be studying and certifying for in 2025.

💥 This episode is brought to you by our valued sponsor and friends at Aikido!💥
Aikido is a no-nonse platform that helps developers get security done. It consolidates multiple scanning tools like code analysis, dependency analysis, and cloud security into a single platform. Aikido’s superpower is its ability to remove false positives, so you can focus on the real issues. Aikido not only helps you find true vulnerabilities but their new AI features auto triage and even fix issues for you.
Aikido is FREE for small teams or anyone wanting to simply explore so check it out today at aikido.dev

You've probably seen Mumshad's courses. He has been another person like myself who, for almost a decade, has been making container courses on Docker, Kubernetes, all the tooling. Now he's running a giant platform of learning and they're introducing AI into your learning and certification prep, courses, and skills labs. And we go through all of it.

We talk about all of the Linux Foundation certifications they cover. They've launched over 100 courses now on their platform and they cover a lot, if not all of the Linux certifications, especially around Kubernetes and the Cloud Native ecosystem. I'm a huge fan of that. I think this is great stuff for everyone, especially if you're early in your career and you're using certifications as a way to prove your expertise or you're like me, you've been around forever and you want to show that you're up to date.

There's also a video version of this show on YouTube.

Bret and Nirmal recorded this special offline episode at KubeCon North America in Salt Lake City. We hung out at the AWS booth to break down the major trends and developments from the conference.
The event drew a record-breaking 10,000 attendees, with roughly half being first-timers to the Cloud Native ecosystem.

Starting with Cloud Native Rejekts and moving through the pre-conference events, we noticed Platform Engineering emerged as the dominant theme, with its dedicated conference track drawing standing-room-only crowds.

The main conference showcased a notable surge in new vendors, particularly in AI and security sectors, representing about a quarter of all exhibitors. We dissect the key engineering trends, ongoing challenges in Cloud Native adoption, and insights gathered from various conferences including ArgoCon, BackstageCon, and Wasm Day. In our 40-minute discussion, we tried to capture the essence of what made this year's KubeCon significant. It's a great listen whether you couldn't attend or if you're a veteran of the Cloud Native community.
