5/5 And as with every KubeCon, it was also great to meet all kinds of old and new friends, and remember the "good old times".

4/5 And those who already used it seemed mostly like happy users. Our maintainer track talk was also successful and very well attended. Kudos to Daniel Mulder and Sahil Sharma for their help!

3/5 But it turns out I was wrong. Strimzi is on fire (and no, for once, it is not a dumpster fire)! We were busy most of the time and rarely had time to munch on some snacks or take a sip of coffee. And the best of it, most people already used Strimzi, or at least knew about it.

2/5 I was mainly afraid that we would be standing there, alone, the whole afternoon, all three days ... and look like complete idiots. I was actually worried about that since we signed up for it with @ppatierno.

1/5 KubeCon is over, and I'm traveling back from Amsterdam to Prague. This was the first #KubeCon #Strimzi took part in the project pavilion with our own kiosk. A week ago, when going to KubeCon, I was a bit nervous about how it would go.

#Kubecon is in the air ...

Prague to Amsterdam ... from the start till the end. Apart from the early morning start it was a fine ride ... #KubeTrain #NoAirplaneMode

Another major milestone on the road to #Strimzi 1.0.0! If you want to learn more about our journey, come to the talk I have with Paolo Patierno at #KubeCon in Amsterdam next week ... kccnceu2026.sched.com/event/2EF6l/...

On 9th March 2018, we released #Strimzi 0.2.0 - the first Strimzi release following the operator pattern. So ... HAPPY BIRTHDAY STRIMZI! 🥳🥂🥳

Next stop: #Strimzi 1.0.0!

March is here. And that means #KubeCon starts in a few weeks. With Paolo Patierno, we will talk about #Strimzi 1.0.0 in the maintainer track. And for the first time, we will also have a Strimzi kiosk in the project pavilion. Hope to see you in Amsterdam!

Just a small change ... but another big step towards the #Strimzi 1.0.0 release ...

And that was another week of my life I will never get back 😫.

Finding CVEs in your own project sucks. No sense of achievement, no feeling of accomplishment. Just banging my head against the desk because I didn't find this during the review. 🤦‍♂️🤷‍♂️

Last chance to apply for the current term of LFX Mentorship. One of the projects is a #Strimzi plugin for the @headlamp.dev ... github.com/headlamp-k8s...

4/4 Stage three:
* The snow piled on the side of the cleaned sidewalks starts to melt, the water flows onto the sidewalk, and freezes overnight ... it is hard to walk on it again
* The snow on the uncleaned sidewalks melted away and they now dry and easy to walk on

3/4 Stage two:
* The cleaned sidewalks are now dry and easy to walk on
* On uncleaned sidewalks, the fresh snow turned into ice, and the uncleaned sidewalks are now hard to walk on

2/4 Stage one:
* The sidewalks that were cleaned of the fresh snow were not cleaned properly and are icy, slippery, and hard to walk on
* The uncleaned sidewalks still have the fresh snow on them and are easy for walking

In-Place Pod Resizing in Strimzi YouTube video by Jakub Scholz

2/2 So I put together a prototype youtu.be/983tFK2327A and a proposal github.com/strimzi/prop.... Let's see if it helps us to build something useful in the future ... 🤔

1/2 In-place Pod resizing was one of the interesting features that graduated to stable in #Kubernetes 1.35. While in-place changes to memory are limited in Java, it might help to give #Strimzi users some more flexibility.

2/2 It is pretty hard to derail me when I set my sights on some goal 😜

1/2 So far so good ... and according to the plan:

✅ 1.0.0 and v1 CRD API Proposal (September 2025)
✅ Strimzi 0.49 + v1 CRD API (November 2025)
✅ Strimzi 0.50 (January 2026)
🔜 Strimzi 0.51 (February 2026)
🔜 #KubeCon Europe talk (March 2026)
🔜 Strimzi 1.0.0 (April 2026)

4/4 Or will it be that the world where AI does everything does not need clean code and APIs anymore, because - unlike humans - the AIs using the API can deal with it easily?

3/4 But how will this work in the AI world? AI seems to love messy spaghetti code, where you just add new features over the others. Will it learn how to do a clean and future-proof API design one day? Will it know when to refuse the new feature and instead request a refactoring?

2/4 Almost every developer can add support for yet another feature by adding gazillion new options into a messy API. But it takes a lot of experience to know when to pause and do some refactoring first in order to have a nice and clean design.

1/4 Maintaining a project is not just about new features and bug fixes. You need long-term thinking, planning, and design. You have to make sure your APIs have the right shape, are easy to use, and can be extended again in the future. You have to deal with technical debt. Etc.

Yesterday was not just the last day of 2025, but also my last day at Red Hat. Now I'm looking forward to what 2026 will bring ...🤞

Release 0.7.0 · scholzj/kekspose Main changes since 0.6.x 0.7.0 introduces a new proxyless model. It no longer uses a Kafka proxy deployed inside the Kubernetes cluster in an additional pod. Instead, all proxying is done directly ...

3/3 Give it a try in the new 0.7.0 release: github.com/scholzj/keks... ... and if you run into any issues, make sure to open an issue or let me know 😉
