are we really still doing this lol?

>> Kubernetes is feature-rich, yet these “enterprise” capabilities turned even simple tasks into protracted processes.

I don't agree. After learning the basics I would never go back. It doesn't turn simple tasks into a long process. It massively simplifies a ton functionality. And you really only need to learn 4 or 5 new concepts to get it off the ground.

If you have a simple website you don't need Kubernetes, but 99% of devs are working in medium sized shops where they have multiple teams working across multiple functionalities and Kubernetes helps this out.

Karpenter is not hard to set up at all. It solves the problem about over-provisioning out of the box and has for almost 5 years.

It's like writing an article: "I didn't need redis, and you probably don't either" and then talking about how Redis isn't good for relational data.

Earlier quoted context omitted.

So, let's say you want to deploy server instances. Let's keep it simple and say you want to have 2 instances running. You want to have zero-downtime-deployment. And you want to have these 2 instances be able to access configuration (that contains secrets). You want load balancing, with the option to integrate an external load balancer. And, last, you want to be able to run this setup both locally and also on at least…

Do you know of actual (not hypothetical) cases, where you could "flip a switch" and run the exact same Kubernetes setups on 2 different cloud providers?

Yes, but it would involve first setting up a server instance and then installing k3s :-)

Interesting that the mania for over-investment in devops is beginning to abate. Here on Hacker News I was a steady critic of both Docker and Kubernetes, going to at least 2017, but most of these posts were unpopular. I have to go back to 2019 to find one that sparked a conversation: https://news.ycombinator.com/item?id=20371961 The stuff I posted about Kubernetes did not draw a conversation, but I was simply document…

Serverless containers.

Effectively using Google and Azure managed K8s. (Full GKE > GKE Autopilot > Google Cloud Run). The same containers will run locally, in Azure, or AWS.

It's fantastic for projects but and small. The free monthly grant makes it perfect for weekend projects.

Start-ups that don't need to scale will quickly go away, because how else are you going to make a profit?

How have you been going since 2005 and still not understand the economics of software?

The attraction of this stuff is mostly the ability to keep your infrastructure configurations as code. However, I have previously checked in my systemd cofig files for projects and set up a script to pull them on new systems. It's not clear that docker-compose or even kubernetes* is that much more complicated if you are only running 3 things. * if you are an experienced user

Having done both: running a small Kubernetes cluster is simpler than managing a bunch of systemd files.

I've worked at a few tiny startups, and I've both manually administered a single server and run small k8s clusters. k8s is way easier. I think I've spent 1, maybe 2 hours on devops this year. It's not a full-time job, it's not a part-time job, it's not even an unpaid internship. Perhaps at a bigger company with more resources and odd requirements...

I think you are proving the point; there are very, very few applications that need to run on two cloud providers. If you do, sure, use Kubernetes if that makes your job easier. For the other 99% of applications, it’s overkill.

Apart from that requirement, all of this is very doable with EC2 instances behind an ALB, each running nginx as a reverse proxy to an application server with hot restarting (e.g. Puma) launched with a systemd unit.

Why does a startup need zero-downtime-deployment? Who cares if your site is down for 5 seconds? (This is how long it takes to restart my Django instance after updates).
