Title: April Fools’ Day Blues in 2019

---

Today marks a day typically filled with pranks and jests. But for many of us, this day was just another reminder that our infrastructure has to be robust enough to handle the unknown. It’s been a wild ride, especially as we navigate the shift towards platform engineering and the increasing complexity of Kubernetes.

I had a particularly tough week dealing with some pesky issues related to eBPF (extended Berkeley Packet Filter). For those who aren’t familiar, eBPF is gaining traction for its ability to inject code into the kernel, making it incredibly useful for monitoring, tracing, and security. However, like any new tool in our stack, there’s a learning curve.

Last week, we encountered some strange network performance issues on one of our critical services. The logs showed nothing unusual, but somehow requests were timing out or taking an eternity to process. I dove into the system, suspecting something was amiss with our eBPF setup. After hours of debugging and tracing every possible path, it turned out that a recent update to the eBPF module had introduced a subtle race condition.

The fix involved rewriting some of the kernel code and recompiling the module. It’s moments like these that make you appreciate the complexity of even what seems straightforward in our stack. The irony is not lost on me—the day we’re supposed to be playing pranks, I’m spending it debugging code that took a turn for the bizarre.

On a more serious note, platform engineering and internal developer portals like Backstage are really taking off. Our team has been tasked with creating an internal portal where developers can easily find all the tools they need, documentation, and guidance on how to deploy their services. It’s exciting to see the vision coming to life, but it’s also a lot of work. We’re trying to balance ease-of-use with security and compliance requirements, which isn’t always easy.

Speaking of internal tools, we’ve been exploring ArgoCD for our GitOps needs. While Flux has matured significantly, ArgoCD offers some unique features that could really streamline our deployment process. However, the learning curve is steep, and there’s a lot of trial and error involved in figuring out best practices.

The week wasn’t all about tech though. The world seemed to be on edge with events like Julian Assange’s arrest and Google blocking someone for creating a web browser. It’s crazy how such big stories can sometimes feel irrelevant in the day-to-day grind, but they are constant reminders of the broader context we’re operating within.

In conclusion, April 1st might have been a day to pull pranks, but it’s also a reminder that as platform engineers and DevOps professionals, our days are filled with troubleshooting real issues, learning new tools, and adapting to changing landscapes. It’s a blend of laughter and stress, all wrapped up in the relentless pursuit of making systems work better.

Happy April Fools’ Day—hopefully, next year we can focus more on jokes than bugs!
