Early Bird is live
50 Early Bird seats.
First come, first served.
Tickets just opened on the CNCF community platform. The Early Bird batch is capped at fifty. Once these are gone the price moves to Regular and stays there until the room fills. Last year that happened well before the door.
- 50 Early Bird tickets only, then the door closes on this tier.
- Tier 2 CNCF rules cap the whole room at 600 seats total.
- Individual community ticket. We can't issue a company invoice or VAT receipt against an Early Bird seat. For corporate billing, wait for the Regular Corporate tickets to open, or write to [email protected] to lock seats in advance.

EBKCDSOFIA2026
Registration is handled by the CNCF community platform (Bevy). You'll be asked for your name + email there.
Why come
Three good reasons
The room is a mix: Kubernetes maintainers, platform engineers running clusters at scale, SREs, security folks, and the CTOs that pay for it all.
See what production looks like
Engineers from Bulgaria and beyond walk through how they actually run clusters: what broke, what they tried, what stuck.
Meet the rest of the room
Long breaks on purpose. Bring a question, leave with a name and a Slack handle from someone who has solved it.
