KCD Budapest 2026

On October 30, 2026, KCD Budapest met for the second time. It is a local Kubernetes community day organized by enthusiastic people from the CNCF community.

The venue was a well-regarded university in Budapest, and its students also had the pleasure of joining the event, meeting and talking to many representatives of the Kubernetes ecosystem.

At 14:40, Gergely Bräutigam presented in Room 1 on Sovereign Cloud and Air-Gapped Delivery with Open Component Model. The presentation focused on introducing the problem of getting software into an air-gapped or sovereign environment where pieces of the application need to travel with the application itself, so it doesn’t try to call them from public locations; instead, it should look for them in the new environment.

The presentation was largely similar to what Jakob Möller presented during his talk at Sovereign Cloud Days 2026 with a few differences.

Gergely, for better or worse, chose to try something new, and hand-drew their slides. You can page through them here:

The message

Gergely’s presentation focused more on why it’s important to be aware of what travels with your application. Supply chain security is nothing to sneeze at, looking at the weekly exploits in the Node ecosystem. From there, it showed how OCM can help define the various components, track them, and then deploy them in an air-gapped environment. The deployment and the upgrade flow ran with the WiFi disabled on Gergely’s machine, proving that all parts of the application were fetched from the local registry instead of public sources.

The application

There was also a bit of a change in the application to make the presentation and the message a bit more memorable and flashy. The app was a basic Asteroid web game with a backing database. The upgrade brought a new version of the game that added different firing modes and power-ups to the ship.

Explore OCM yourself

The talk closed with a simple adoption path:

  • Pilot: pack one product as an OCM component.
  • Standardize: make OCM the default way you deliver components.
  • Steward: bring yourself into the OCM community.

The Getting Started guides are the fastest way to the first step, and the community page shows how to reach us.

Huge shoutout to the people organizing KCD Budapest and Óbuda University for having us and providing the venue. See you next year! 🤞
