Learn Kubernetes Weekly issue 31
Sync 10k Argo CD apps, Kubernetes as a platform vs API, 100k concurrent jobs, tcpdump+knsiff+wireshark
14 Jun 2023
Howdy!
Just a quick note before you start reading this issue.
I shared one (interesting) Kubernetes post every week for the past five months, and you can find the recap of all the posts here.
I won't lie; it's been hard! But I hope this helps you with your Kubernetes journey!
