Backup S3, Google Drive, iCloud, Notion with Plakar
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.

Your Images are Out of Date (probably) - The Silent Rebuilds problem
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!

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. ★Show Links★ Cast AI website Cast AI YouTube Channel Check out the video podcast version here: https://youtu.be/yINNWxRywv4 Creators & Guests Cristi Cotovan - Editor Bret Fisher - Host Beth Fisher - Producer Dan Muret - Guest Philip Andrews - Guest You can also support this podcast by subscribing to my YouTube channel and my monthly newsletter at bret.news!

Could 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 new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code. You'll leave with a deep understanding of risks and mitigations as well as a list of helpful tools to keep your repos safe, including my new "gasa" tool for scanning your repos and orgs. 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. ★Show Links★ Embrace website Embrace GitHub repository Embrace docs Check out the video podcast version here: https://youtu.be/HHpn3OqMrbU Creators & Guests Cristi Cotovan - Editor Bret Fisher - Host Beth Fisher - Producer Andrew Tunall - Guest You can also support this podcast by subscribing to my YouTube channel and my monthly newsletter at bret.news!

AI 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.

What's Coming in 2025?
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. 😇 My new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code. You'll leave with a deep understanding of risks and mitigations as well as a list of helpful tools to keep your repos safe, including my new "gasa" tool for scanning your repos and orgs. ★Topics★ My work at KubeCon EU in London What's next for this Podcast and my YouTube What's up with AI for DevOps?

Docker Build the best way with Docker Bake
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. 😇 My new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code.
