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.

😇 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.

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!

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. 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.

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.
