Right now we're 4 weeks in and IT and 2 guys want it. We're 3 server nodes + 2 client nodes big, 128G RAM, 16 cores, 32 threads. Please go ahead and call this tiny and irrelevant. I'm aware and under the same assumption. I've dealt with individual servers around 4x that size.
But, go ahead and ask me again in 3 or 6 month. We'll migrate around 10 HW servers as nomad clients, we'll probably get HW capacity from our sister company and then we'll start interacting with the 2 other sister companies. If we get all of their resources into nomad, we'd be up to 60 - 80 beefy metal servers. And those 2 other sister companies are in pain for easy windows resources. If nomad can do that properly, I'll be sold for it quite hard. It'll be fun.
I'm not the person you're directly replying to but I'm the guy who originally asked the question at the top level, and I can say your needs right now are far bigger than mine. Right now my 5-container Dokku host has 4GB of RAM with 2 CPUs, but we're expecting to ramp up quickly.
It's good to hear your input as I expect to be a similar size to you in a year or two. Far from irrelevant. I'll have to look into it.
The problem is if you come on here and talk about how great nomad is, then only later say you are only running five nodes, that gives people false impressions. Kubernetes is tested regularly with 5000 nodes. To get to that level takes an entirely different level of software to be able to run a cluster that large reliably without issues.
Isn't the entire purpose of this threat that Kubernetes is a big solution made for big problems and smaller problems might not need that big of a solution?
The comment was in response to a question I asked about "do I really need something as big as Kubernetes". Not sure why people are picking apart this answer when it seems to answer my question quite well.
The purpose of this threads, and threads like it, is they turn into a "nobody needs kubernetes" when xyz exists, and they completely ignore the fact that kubernetes is not meant for small shops.
I didn't see yours was in the context of a small cluster, since I was reading the whole thread, so I apologize. It seems that every single comment is roughly the same as yours, though, and they act as if anyone who chose kubernetes/openshift is clearly an idiot. There's a reason big clusters use it, but the people running the large clusters don't come on HN to comment. Look at the openai blog, for example.
There's a reason the community is so large.
There's a reason people are developing tons of tools around it.
