A small, lightweight, m1-friendly, fully-portable (yay Docker) kubernetes setup & some goodies

Kube Productivity teengz

Kubernetes management

• https://k8slens.dev/ -- LENS is like a full-blown IDE for Kubernetes. Hook up any of your kubectl contexts or files to it and you're off to the races!
• https://octant.dev/ -- Octant is like Lens, but different. In some ways, better, albeit it feels slightly slower...but it's dope also!
• https://k9scli.io/ -- Manage your kube clusters in style via one of the coolest, most-bad ass CLIs ever

Debugging/Observing

• https://github.com/boz/kail -- VIEW A LIVE TAIL OF ALL (or some filtered set) of services, pods, deployments, nodes, etc... with just one, simple, cli command

Local Kubernets

• https://k3d.io/ -- a lightweight k3s wrapper for quickly spinning up local k3s clusters
