CatOps Digest 2024-11-03
What was on CatOps in the last couple of weeks...
This is it, the last month of the autumn. A very warm autumn, I must say. When I moved to Berlin five years ago, it was a non-stop rain at this point. Today, on another hand, was sunny and pleasant.
Charity
Many thanks to y’all, folks! Together we’ve managed to close all the fundraisers I posted on the channel in these two weeks. So, I’d like to link some fundraisers from our friends.
Make sure to check out recent fundraisers by “Dzyga’s Paw” (they have a functional English version of their website)
“Gurkit” fundraiser by Kolo, which is almost done. The page is only available in Ukrainian, but the donation widget is in English ;)
A fundraiser by our friends at DOU.ua. It’s almost 90% done!
Time Sensitive
Shells and Scripting for Seasoned Admins is a book bundle by O’Reilly that has books about Linux, shells, CLI utils, etc. It’s still available for 15 more days as of today.

Kubernetes networking: service, kube-proxy, load balancing - a Kubernetes networking explainer. It uses IPTABLES as an example, which are not used anymore in many setups. However, it’s easier to use them as an illustration, since they are text-based.
Mantis - a new configuration management tool that tries to bring the best of DSL and Turing-complete programming languages together by using the CUElang for configuration. Keep in mind: it’s not production ready!
When Kubernetes and Go don’t work well together - a story of debugging a Go application inside Kubernetes. I do not fully agree with the premise of this article, but it has some insights into how Go’s garbage collector works.
8 ways to speed up your Ansible playbooks - a how-to by RedHat on how to improve the speed of your Ansible playbooks. Just brief actionable recommendations without any unnecessary text.
That’s all for today, folks! See you in two weeks. If you don’t want to wait so long, you can subscribe to the Telegram channel to get all these articles as I find them.
