what is k9s and why is it needed?

k9s is an open source terminal based ui that simplifies the management and monitoring of k8s clusters by providing an interactive way to view and manage resources like - pods, deployments, and services

pressing num keys will list pods in specific namespaces ex- 0 (for all namespaces), 1 (for namespace a), 2 (for namespace b) etc.
use vim navigations to travel the list (h, j, k, l)
shift + a → sort based on age of the pod
shift + s → sort based on status (running or completed)
press “l” while on any pod to see its logs
search anything like vim using ”/”
: → change resources - pods, deployments, namespaces, services Note: to check logs natively using kubectl command do the following:

kubectl logs <podname> | less

attach to pods directly by pressing “s” by opening shell
press “d” to go to the description of a pod
shift + f → port forward options
press “e” on any resource to edit it live
press “y” to get the yaml for the resource
ctrl + k to kill/delete a resource
k9s is just like a native unix tool making the keybindings extremely evident Note: when doubtful use the ”?” on any resource to see the keybindings or refer official docs
