DevOps and Docker Talk: Cloud Native Interviews and Tooling

Bret is joined by the founders of Plakar - Julien Mangeard and Gilles Chehade - to nerd out over backup engineering. The kind where you're building your own file formats and cryptographic layers, not just wiring up cron jobs. We get into how Plakar deduplicates and encrypts at the source so your cloud provider never sees your keys. Also, their snapshot model has no chain dependencies, which means you can delete any backup without breaking the others. We had a fun hour of backup horror stories, ransomware pragmatism, where I'm lobbying hard for a Docker volume integration.

...

Container base images (like Official Docker Hub images) are often updated without new tag versions. I call this Silent Rebuilds. There's no way to know this happens without image digest-checking automation like Dependabot and Renovate with specific settings. Failure to keep up-to-date is a prime source of vulnerabilities that can lead to serious security breaches. Automate the updates!

I'm joined by Nirmal Mehta of AWS and Viktor Farcic from Upbound, to go through our 2025 year in review. We look into the AI tools that consumed us this year, from CLI agents to terminal emulators, IDEs, AI browsers - what worked, what flopped, what's worth your time and money, and what we think isn't!

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...

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.
