No, you don’t need to do rolling deployments.

Easier than ssh’ing in and running ps?
Don’t get me wrong, k8 is great if you need to manage a complex system. It’s just that most of the time you can choose to not build a complex system in the first place.
Have you ever been thrown into an unknown environment? SSH'ing where exactly? Oh but this runs at hosting partner X? That runs at hosting partner Y? Oh but this service is actually behind a reverse proxy running on box Z. Oh you need to RDP to a jump-server to SSH to those machines? Documentation? You mean these outdated Word documents and Excel sheets? And down the rabbit-hole you go. Fun!
And don't say that doesn't happen, I'm a freelance sysadmin - and am exactly in an environment like that right now, it's not the first, and won't be the last. To get a complete picture here, I needed 2 whole months for everything outside the Openshift clusters.
The stuff running on openshift was pretty simple, there is the master, here are your credentials - and that's it. The rest is pretty easy to figure out if you've worked with k8s/openshift. The biggest problem was knowing if the app in question ran on Openshift or somewhere else.
Yes, you’re describing pretty much every environment I’ve ever worked in.
I’m not arguing that k8s is the wrong tool to manage that kind of complexity. I’m arguing that, in almost all cases, that kind of complexity is completely unwarranted.
