Kubernetes feels like Javascript has reached the sysadmins, new updates, libraries, build tools every week.
It's mainly good for keeping high paid people employed, not keeping your servers stable.
I ran a cluster 1.5 years in production, took me so much energy. Especially that one night where digital ocean managed cluster forced an update that crashed all servers; and there was no sane way to fix it.
I'm back to stability with old school VPS; it just works. Every now and then you run a few patches. Simple & fast deploys; what a blessing.
