goldilocks VS minikube

There's also tools like Goldilocks that can help with resource request planning.

I recently installed this into our cluster and it provides you a recommendation of what your resources should be set to based on VPA in monitor mode. https://github.com/FairwindsOps/goldilocks

While not directly what you're asking, a tool like Goldilocks combined with Kubernetes' Vertical Pod Autoscaler can give you an idea of the real CPU and memory consumption of your applications over a period of time. It's mainly used for cloud cost control, but could be useful.

We use it in a limited fashion as part of Goldilocks. Not all namespaces have it enabled, but any team that wants to use it can request their namespace be enabled.

We use https://github.com/FairwindsOps/goldilocks (zero affiliation) in our load testing environment and work from the recommendations there.

Come help us build great open source and commercial software for Kubernetes! You may know us from projects like Polaris and Goldilocks. We're building an inclusive, learning-driven, remote-first culture and are looking to grow our team.

With the containerized Node.js/Express API, I could run multiple containers, scaling to handle more traffic. Using a tool called minikube, we can easily spin up a local Kubernetes cluster to horizontally scale Docker containers. It was possible to keep one shared instance of the database, and many APIs were routed with an internal Kubernetes load balancer.

Install Minicube - a tool that allows us to spin up a Kubernetes cluster in a local machine Run minikube start to start your Kubernetes cluster Run minikube dashboard to spin up a web-based user interface that allows you to manage your Kubernetes cluster

If you're just messing around, just use kind (https://kind.sigs.k8s.io) or minikube if you want VMs (https://minikube.sigs.k8s.io). Both work on ARM-based platforms.

You can also use k3s; it's hella easy to get started with and it works great.

A Kubernetes distribution: You need to install a Kubernetes distribution to create the Kubernetes cluster and other necessary resources, such as deployments and services. This tutorial uses kind (v0.18.0), but you can use any other Kubernetes distribution, including minikube or K3s.

https://github.com/kubernetes/minikube for local learning that's lightweight.

Haven’t dabbled with minikube yet, but there’s a whole thread about this error here: https://github.com/kubernetes/minikube/issues/9798
