This is getting downvoted for cynicism maybe, but I feel it's the most important advice here. Know /when/ to use Kubernetes.

It's very often the wrong tool to deploy our tiny app but many of us go along with it because it ticks some management boxes for various buzzwords, compliance, hipness, or whatever. Once you get out this hammer factory, it's a big and complicated one, so you will probably need a full time team to understand it and manage it. It's also a metric hammer factory, so you'll need to adapt all your other tooling to interoperate. Most of us can get by with lesser hammer factories, even k3s is less management.

If you just need to deploy some containers, think hard if you want to buy the whole tool factory or just a hammer.

This kind of comment is on every single HN post about Kubernetes and is tiresome. I also think it's off topic (TFA is about kubectl tricks, not about the merits of K8s).

I think it's important to have comments like those as Google, who does not use Kubernetes, is exerting a lot of pressure on the industry to adopt it. It is an extremely complicated tool to learn to use well and companies act like there aren't reasonable alternatives.

Those of us who have gone through it are often coming back with war stories saying to use something else. Some of us have invested thousands of man hours into this already and have strong opinions. At the very least, give Nomad a look. It is maybe a tenth of the effort to run for exactly the features most people want and then some.

People need to be made aware that there are options. I have friends at companies that have large teams just dedicated to managing Kubernetes and they still deal with failure frequently or they spend their entire day-to-day tuning etcd.

We get paid because we know these tools. It's why we're desired: because the company thinks they want K8s or they're one foot in EKS and they're doubling down. We don't get hired because we dare to suggest they dismantle their pilot cluster and take a sharp turn into Nomad.

Most of us aren't the engineering heads of our departments. So you'll forgive us if we continue pushing the moneymakers we have in our heads and setting up our homelab clusters. I want to be paid, I want to be paid well. It may as well be pushing the technology stack that scales to megacorps because who knows maybe I'll make it there one day.
