Do you guys think k8s is doing a job which previously the jvm did in enterprise? i.e. if everything is on the jvm, building distributed systems doesn't require a network of containers. Can k8s success be explained partly due to the need for a more polyglot stack?

Come on. What? Setting up a load balancer or nginx is considered complex now?
> What? Setting up a load balancer or nginx is considered complex now? It's not complex to set up a load balancer in a given specific environment. But it's another kind of ask to say "set up a load balancer, but also make it so that the load balancer also exists in future dev environments that can be auto-set-up and auto-teared-down. And also make it so that load balancer will work on dev laptops, AWS, Azure, google,…
My question is: Why is only k8s so popular when there are better alternatives for a large swath of users? I believe the answer is "Manufactured Hype". k8s is from a purely architectural standpoint the way to go, even for smaller setups, but the concrete project is still complex enough that it requires dozens of different setup tools and will keep hordes of consultants as well as many hosted solutions from Google/AWS/…
Then a lot of people drink the koolaid and apply it everywhere / feel they're behind if they aren't in Kubernetes.
We are not in Kubernetes and have multiple datacenters with thousands of VMs/containers. We are doing just fine with the boring consul/systemd/ansible set up we have. We also have somethings running in Containers but not much.
Funnily enough at the OSS summit I had a couple of chats with people in the big companies (AWS, Netflix, etc.) and they themselves have the majority of their workflows in boring VMs. Just like us.

Reading this charitably: I guess I agree. k8s is definitely overpowered for my needs. And I'm almost certain my blog or my business will never need that full power. Fully aware of that. But I'm not sure one can find something of "the right power" that has the same support from cloud providers, the open source community, the critical mass, etc. [1] Eventually, a standard "simplified" abstraction over k8s will emerge.…
Curious why run it at all? The cost must be 10 times more this way. It is mostly for the fun of learning. I come from the opposite approach. I have 4 servers two digital ocean $5 and two vulr $2.50 instances. One holds the db. One server as the frontend/code. One server to do heavy work and another to server a heavy site and holds backups. For $15 I'm hosting hundreds of sites, running so many background processes. I…

Well, set me up one. :P
my pubkeys are below, send me an ip address and port to an ssh server https://github.com/cameronnemo.keys

1) It solves many different universal, infrastructure-level problems. 2) More people are using containers. K8s helps you to manage containers. 3) It's vendor agnostic. It's easy to relocate a k8s application to a different cluster 5) People see that it's growing in popularity. 6) It's Open source. 7) It helps famous companies run large-scale systems. 8) People think that it looks good on a resume and they want to work at a well known company. 9) Once you've mastered K8s, it's easy to use on problems big and small. (Note, I'm not talking about installing and administrating the cluster. I'm talking about being a cluster user.) 10) It's controversial which means that people keep talking about it. This gives K8s mind share.
I'm not saying K8s doesn't have issues or downsides.
1) It's a pain to install and manage on your own. 2) It's a lot to learn--especially if you don't think you're gonna use most of it's features. 3) While the documentation has improved a lot, it's still weak and directionless in places.
I think K8s is growing more popular because it's pros strongly outweigh it's cons.
(Note I tried to be unbiased on the subject, but I am a K8s fan--so much so that I wrote a video course on the subject: https://www.true-kubernetes.com/. So, take my opinions with a grain of salt.)

Have you tried or considered Nomad (from the makers of Terraform)?
can it handle networking (including load balancing and reverse proxies with automatic TLS) or virtualized persistent storage? Make it easy to integrate common logging system? Cause those are the parts that I miss probably the most when dealing with non-k8s deployment, and I haven't had the occasion to use Nomad.
- Yes, just added CSI plugin support. Previously had ephemeral_disk and host_volume configuration options, as well as the ability to use docker storage plugins (portworx)
- I haven’t personally played with it, but apparently nomad does export some metrics, and they’re working on making it better
