    K8s Maxxing with AI-Native Platform Engineering Stack with OpenChoreo

    OpenChoreo is a “batteries included”, AI-native Kubernetes platform stack for Platform Engineers that combines GitOps, Observability, AI Agents, and Workflows into a custom K8s distribution “super pack” that is managed via Backstage, CLI, API, or MCP. Check out the video podcast version here: https://youtu.be/AqGWjxEfj2g 😇 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. ★Show Links★ OpenChoreo on CNCFOpenChoreo on GitHubOpenChoreo websiteSRE Day walkthroughCreators & Guests Cristi Cotovan - Editor Bret Fisher - Host Beth Fisher - Producer Sameera Jayasoma - Guest Lakmal Warusawithana - Guest You can also support this podcast by subscribing to my YouTube channel and my monthly newsletter at bret.news!

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    Your Images are Out of Date (probably) - The Silent Rebuilds problem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

    AI Wins and Misses for 2025

    I'm joined by Nirmal Mehta of AWS and Viktor Farcic from Upbound, to go through our 2025 year in review.

    Move K8s Stateful Pods Between Nodes

    Bret is joined by Philip Andrews and Dan Muret of Cast AI to discuss pod live migration between nodes in a Kubernetes cluster. 😇 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.

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. Cast AI dynamically moves your pod to a different node without downtime or data lost. It copies your running pod data, memory, IP address, and TCP connections from one node to another in real time. 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!
