DevOps and Docker Talk: Cloud Native Interviews and Tooling

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!

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 in 2025. I'm so 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://courses.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. ★Show Links★ Embrace website Embrace GitHub repository Embrace docs Check out the video podcast version here: https://youtu.be/HHpn3OqMrbU Creators & Guests Cristi CotovanBret FisherBeth FisherAndrew Tunall You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!

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.

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. ★Topics★ Highlights I'm excited about related to KubeCon What's next for my Podcast and YouTube What's up with AI?

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 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 CloudNative community.

Bret and Nirmal Mehta are joined by Ken Collins to dig into using AI for more than coding, and if we can build an AI assistant that knows us. They touch on a lot of tools and platforms. "We're bit all over the place on this one, from talking about AI features in our favorite note taking apps like Notion, to my journey of making an open AI assistant with all of my Q&A from my courses, thousands of questions and answers, to coding agents and more." Ken is a local friend in Virginia Beach and was on the show last year talking about AWS Lambda, and we've both been trying to find value in all of these AI tools for our day to day work.
