Can I ask people who _don't_ use Kubernetes and maybe have architectures built on proprietary cloud services: how do you manage this?
Immutable infrastructure using Nix/NixOS.
NixOS, however, I will not recommend as your dev environment. Use a regular distro and use NixOS for your containers.

> you can get these same properties from any of a variety of easier-to-use schedulers such as Fargate, Heroku, or even EC2 autoscaling group Serious question, as I don't have any experience of those, can you scale based on a custom metric? It's probably the one feature of k8s I appreciate the most.
On Heroku, I have written a very small autoscaling script that is called once every few minutes by Heroku Scheduler (like a cronjob). The autoscaling script pulls the custom metric, does some arithmetic, and calls the Heroku API to scale the dyno count up/down as desired. (That script was probably shorter and more readable than this comment.)

If I understood correctly, this means that every time you add a new dependency, it takes 15 minutes to rebuild the first time you `docker-compose up` right? I assume this is due to docker downloading the related image and running the container. If this is the case, isn't this orders of magnitude faster than adding the dependency manually. And aren't the gains are even more significant when we factor the fact that mos…

Yes > If this is the case, isn't this orders of magnitude faster than adding the dependency manually. No. When developing a rails server running locally, you just need to install the new dependency via bundle install (usually takes just a few seconds) and then your server is ready to run…
Not a single mention of elastic beanstalk or App Engine? The best middle ground for small teams who just want one reliable website with minimal scaling (and who can't just choose a nom-aws service).
Do you have any examples of non-proprietary solutions?
I think one of the underrated parts of using something like Kubernetes early (or even w/ simpler orchestrators like swarm or rancher), is that it encourages (and sometimes enforces) architecture best practices from the start. IE, you won't be storing state locally, you'll be able to handle servers being randomly killed, you'll already have horizontal scaling, etc. In my experience the hard part of migrating to contai…
> I good reason not to use kubernetes though is if you know your app is probably never going to scale Suggesting that you can only scale with Kubernetes just isn't true. Our tech stack originally ran on AWS in multi-regions. Then we moved to GCP. The architecture was the same for both: - public facing Load Balancer - instance groups attached to the LB - add health checks so unresponsive instances get killed - add sca…

There are a lot of projects these days that aim to use Kubernetes as a docker-compose environment. I personally use http://skaffold.dev/ with either a local Kubernetes cluster built with https://github.com/rancher/k3d or https://github.com/kubernetes-sigs/kind . I think there's a very easy argument to be made that says that running K8s locally is overkill, but what I will say is that if you run your applications loca…
`kind` and `k3d` are great but I don't think their aimed at being a developer friendly cluster from what I understand. They both require a lot of tweaking and setup to make them look like their a managed kube cluster (LB, storage, ingresses, etc). I wish there was something that could create a kube cluster that: 1. sets up automatic port forwards to my host system 2. handles ingresses by binding port :80 on my system…

Talking about kind and k3s, does anyone know how to load a local docker image into a k3d cluster? The command is supposed to be: 'k3d image import --cluster myCluster image:tag', but it fails with "Failed to start exec process in node 'k3d-myCluster-tools'" On kind it works fine with 'kind load docker-image --name myCluster image:tag'. I'm using WSL2.

> people were amazed by the productivity gains Yeah, docker compose is great for running distributed apps locally when everything “just works”. The problem is that it also impedes development when the compose setup isn’t fully optimized. I work on dockerized rails apps, and whenever a new dependency is added, it can take 15 minutes to rebuild the image, which completely breaks my flow. Docker also creates a ton of da…
At my current company, since I'm using gRPC, the build contexts for my containers are annoyingly large and I'm definitely feeling this. It's a massive pain and really annoys me but If I had to choose between 40 minutes of stressful debugging of someone else's config files vs 40 minutes of waiting for a command to finish, I'd take the latter. Long term I'm planning on moving these builds to bazel and taking advantage…
Then just have a different Docker-compose config for prod
