Jenkins Agents On Kubernetes
default is where any actions which require a namespace will go into if one is not explicitly defined in a default setup (tools such as kubens can alter this behavior). In the context of Jenkins, namespaces are a useful way to allow isolation of individual Jenkins instances that want to utilize the same Kubernetes cluster. Creation of a namespace is a simple option to kubectl:

Tool to manage kubeconfig configurations
Here you go: https://github.com/ahmetb/kubectx and https://kubecm.cloud/
-
Setting kubectl context via env var
check out kubectx/kubens https://github.com/ahmetb/kubectx very handy tool to permanently switch context/namespace

[ANN] Kele: Snappy Kubernetes cluster management in Emacs
For a peek at what's currently possible, visit the documentation site, in particular the Usage section. For this initial release, it has feature parity with kubectx and kubens and that's about it, but there's lots of room for growth.

Injecting secrets from Vault into Helm charts with ArgoCD
I also encourage you to install kubectx + kubens to navigate Kubernetes easily.
- What daily terminal based tools are you using for cluster management?

I wrote a setup guide for developers to practice and learn Kubernetes locally
I would recommend those 2 tools to easily switch between contexts and namespaces : kubectx and kubens

Building Llama as a Service (LaaS)
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.

Can I scale my dockerized Flask solution with Kubernetes?
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

K3s β Lightweight Kubernetes
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.

Implementing TLS in Kubernetes
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.

Best way to install and use kubernetes for learning
minikube (https://github.com/kubernetes/minikube) - based off of docker machine, uses driver for backend, so can use KVM, Vagrant, or Docker itself to bootstrap K8S cluster.

Running Kubernetes locally on M1 Mac
When I run minikube start --driver=docker (having installed the tech preview of Docker Desktop for M1), an initialization error occurs. It seems to me that this is being tracked here https://github.com/kubernetes/minikube/issues/9224.
