kubectl-ipick

A kubectl plugin that is easy-to-use, flexible, and interactive You will have the ability to roam around the Kubernetes world with a blazing fast selection menu

Introduction

Let's say we'd like to edit a resource in kubernetes using native kubectl and compare it to using kubectl-ipick. First, we'll start by trying to filter out by the relevant resource type and identify the correct resource. So we'll run:

kubectl get configmap

In some cases, we just noticed it's not the right namespace, so we'll run again:

kubectl get configmap -n <namespace>

Then, we'll need to go over the list, identify our resource and copy the resource ID and trigger edit command.

kubectl edit configmap <configmap_id> -n <namespace>

This is basically what we need to do for every single resource in our cluster as resource IDs keeps changing. Instead, we'll leverage kubectl-ipick to minimize the number of operations. In order to modify a single resource with a single operation, we can run:

kubectl ipick edit configmap --all-namespaces

This command will query all namespaces and present a list for us to pick from, once we've chosen the right resource, the plugin will run the command we've passed as argument (edit). And we're done!

➜ kubectl ipick edit configmap --all-namespaces
ID    NAME                                 NAMESPACE
1     cluster-info                         kube-public
2     coredns                              kube-system
3     nginx                                kube-system
select configmap from the list:

You can even use the "like" filter on top of the list to show only resources that contains the supplied string.

➜  ~ kubectl ipick describe configmap --all-namespaces --like nginx 
ID    NAME                              NAMESPACE
1     nginx                             kube-system
2     nginx-load-balancer-conf          kube-system
select configmap from the list:

Recommendation: make an alias to kubectl ipick to increase the speed of your work even more!

alias kp='kubectl ipick'

kubectl-ipick makes our day to day work with kubectl much more faster by listing the resources you wish to edit within a single command. kubectl-ipick
