minikube VS kubernetes

A Kubernetes cluster - we're using a local Minikube cluster (https://minikube.sigs.k8s.io)

To begin with, I don't have a home lab as such, so I'll run everything through minikube. I may switch things up later to get a more "realistic" k8s install, but minikube will be fine for a start.

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.

Recently, I’ve spent some time playing around with Kubernetes (K8s). Having never used it before, I gave it my humble first try. I used it as part of a project where I wanted to use self host some tools on a VPS and write some server code for some life automations and potentially a blog in the future. You can find the Github Repo for the project at the time of writing for it here.

Kubernetes - An open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes Documentation - Official documentation.

A manufacturing company might leverage a combination of Kafka for real-time data streaming, Kubernetes for container orchestration, and dbt for data transformations. They could use Dataplex for unified data management and security across domains. This technology stack would enable the Production Data team to monitor and analyze production metrics in real-time, the Supply Chain Data team to manage and optimize logistics and inventory, and the Quality Control Data team to ensure product compliance and quality. By investing in these tools, the company can effectively support the decentralized data management and governance principles of Data Mesh.

The best method to counter these problems is CloudNativePG operator, this operator manages PostgreSQL workloads on any supported Kubernetes cluster.

Stacklok was founded in 2023 by Craig McLuckie (co-creator of Kubernetes) and Luke Hinds (creator of the OpenSSF project Sigstore), with the goal of helping developers produce and consume open source software more safely.

Kubernetes, an open-source platform for automating the deployment, scaling, and operation of application containers, has become a fundamental tool for modern software development. Here are some of the top Kubernetes commands every developer should know, along with comments explaining their usage:

Orchestration with Kubernetes is simple to set up, but there are some challenges to managing resource usage in a cost effective way.

Said audience member here. "The Kubernetes project" includes a bit more than just https://github.com/kubernetes/kubernetes, but yes that's accurate.

Here's our GCP spend for the past month: https://imgur.com/a/VVJTSKx. Note that does not include a separate AWS cluster that we are migrating jobs too.

A large chunk of this comes from the nature of distributed tests. We need to reproduce the environment, spin up compute, etc. We do have a large problem with flaky tests on the project as well. Whether that's timeouts, memory/cpu consumption creep over time, loads of other things. We talk about how one day we'd like to get to the granulairty of being able to go to a SIG and say, "this flaky test of yours is costing the project $x in retries. Please dedicate some resources to fix it".

How we distribute the artifacts is a whole different conversation. The container world is unique in that voluntary mirrors are not as possible as with linux packages and other binaries.
