Friendly Reminder: 12 Oct is the #CfP deadline for #KubeCon + #CloudNativeCon EU 2026!

I submitted three proposals:
First, my #CDS25 session on fully declarative and reproducible #K8s workloads with #Kubenix.
Second, a deep dive into secure, reproducible #OCI container images with #Nix, beyond #Docker.
Last but not least, together with @FaniD, our case study automating #Keycloak #IAM on Kubernetes via #Nix.

Regardless how the #CfP​s go, looking forward to see you in Amsterdam!

I had lots of fun last week at #ContainerDays chatting about #observability and the @OpenSearchProject In fact, it was my first public speaking as an official OpenSearch Ambassador under The Linux Foundation's OpenSearch Software Foundation 🤩
It was also a good opportunity to share about the new observability technical advisory group we started this month for #OpenSearch.

Had an incredible time at #ContainerDays2025! I'm still amazed by the fantastic feedback on my #Kubenix talk, as well as the tremendous interest in #Nix within the #CNCF and #Kubernetes communities. Thank you all for making my time in Hamburg so memorable!

Day 2 at #ContainerDays 2025

It was so great to connect with people in real life instead of just on LinkedIn, hopefully we’ll stay in touch! 🙌

Some of my highlights today:

How to Provide Kubernetes LoadBalancers with MetalLB and kubeLB?
Mainframes Aren’t Dead — They’re Running Kubernetes and Attesting Confidential Containers (probably the most fun and exciting talk today!)
From VMware to KubeVirt: A Technical Migration Journey
Day-2’000 – Migration from kubeadm+Ansible to ClusterAPI+Talos: A Swiss Bank’s Journey
FROM VMWARE TO KUBEVIRT: A TECHNICAL MIGRATION JOURNEY

Another inspiring day full of technical deep dives and great conversations.

👉 Which session did you enjoy the most today? And what are you looking forward to tomorrow?

Container Days is really great so far, looking forward to some relaxed networking tonight and a chair to sit after standing all day 👴🏻

#CDS25 #ContainerDaysHamburg

First day at ContainerDays 2025, what a ride!

So many inspiring people, products, and talks. The hardest part? Choosing which session to attend, since so many great ones were happening in parallel.

Some of my highlights today:

  • Beyond the Surface: Exploring Attacker Persistence Strategies in Kubernetes
  • KubeNix: Declare Your K8s Workloads Fully Reproducible
  • Dynamic Multi-Cluster Controllers with controller-runtime
  • Kelsey Hightower on stage: Why are we still talking about containers?
  • Beyond the Limits: Scaling Kubernetes Controllers Horizontally

I didn’t make it to the After Show Party today, but I’ll definitely stay longer tomorrow 😄. Already got a lot of insights, learned new things, and refreshed some knowledge.

The best part: all talks are being recorded and will be available on YouTube soon, so nothing is really “missed”!

Which talk was your favorite today, and what’s on your list for tomorrow?

First session of the day at #CDS25, starting of with some #oTel 🎉
Excited to give my talk today at #ContainerDays, stage #K4 at 10:05! I'll show how #Kubenix leverages #NixOS modules to generate reproducible, declarative #Kubernetes manifests, no more #YAML templating. See how #Kubenix connects with #Helm and builds #OCI container images with #Nix, simplifying cloud-native stacks. Don't miss it if you want more control and reliability in your infra!
