A single API for multicloud with Control Plane Sep 18, 2026

Show notes

Control Plane CEO Doron Grinstein joins me to discuss how they’ve created an AI-native cloud API that virtualizes multi-cloud and hybrid cloud to simplify management and ship faster.

🖥️ Watch demos from the live stream.

😇 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.

K8s Maxxing with AI-Native Platform Engineering Stack with OpenChoreo Jun 12, 2026

Show notes

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.

Backup S3, Google Drive, iCloud, Notion with Plakar Mar 20, 2026

Show notes

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Your Images are Out of Date (probably) - The Silent Rebuilds problem Mar 04, 2026

Show notes

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!

Move K8s Stateful Pods Between Nodes Oct 09, 2025

Show notes

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

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.

Swarm 2030. Let's Go! Aug 20, 2025

Show notes

Bret discusses exciting news about Swarm being maintained until 2030.

In this episode, I give an update on the future of Docker Swarm, the renewed long-term support and ongoing development from Mirantis. The news should be reassuring for you, Swarm users. Swarm remains a viable, supported option for your container orchestration needs, at least until 2030.
