The schedule for CiliumCon is out now and I always love to see what the community has been working on with talks ranging from IPv6 only clusters to increasing the scalability of Cilium to diving deep into the kernel to parse FQDNs with eBPF to getting Cilium service mesh into production in 90 days. It will be a whirlwind tour through the hive of activity around the project. Speaking of hive of activity, the eBPF Foundation just announced its first fellowship program with the goal of expanding the eBPF community. I'm looking forward to hearing your ideas on how to grow the buzz around eBPF. Feel free to reach out to me if you have any questions about the program or are interested in applying.

The Post of the Week

Submitted a Pull Request fixing a Renovate dependency issue for Cilium Tetragon. This was a good first issue to get familiar with their setup, and I learned a lot along the way, especially about their CI release pipelines.

As always, if youโ€™ve seen a blog post, a tool, or anything else eBPF or Cilium related that you think the rest of the community should hear about, send them my way. You can either hit reply or join the #echo-news channel on Cilium Slack. You can also find all of the past episodes on the website.
