Weekly Community Meeting

The Cilium contributors gather every Wednesday at 8am PDT, 17:00 CEST, for a one-hour Zoom call open to everyone. During that time, we discuss:

  • the statuses of the next releases for each supported Cilium release
  • the current state of our CI: flakes being investigated and upcoming changes
  • the development items for the next release
  • miscellaneous topics during the open session

If you want to discuss something during the next meeting’s open session, you can add it to the meeting’s Google doc. The Zoom link to the meeting is available in the #development Slack channel and in the meeting notes.


Our Cilium & eBPF Slack is the main discussion space for the Cilium community. Click here to request an invite.
