kubectl oneliners

These scripts can be used as subcommands for kubectl to serve a specific purpose

Installation

sudo cp ./kubectl-* /usr/local/bin/

Desciption

kubectl-resources

This oneliner shows you the resource limits/requests for pods in a namespace or all namespaces

Usage example:

# Supports --all-namespaces
kubectl resources

kubectl-containerids

This oneliner shows you the associated containerids for kubernetes pods. It can be used to debug a container directly on the node. The containerId matches the ID on the node itsself

Usage example:

# Supports --all-namespaces
kubectl containerids

kubectl-geteverything

This oneliner shows all (and by that it means every resource/cr) in a namespace. It requires an argument which is the name of the namespace in question.

It may be used to debug a namespace stuck in terminating state to find out which resources remain.

Usage exmaple:

kubectl geteverything my-namespace

kubectl-finalize-namespace

This is a dangerous script but sometimes necessary to get rid of a namespace which is stuck in Terminating state

Run this script with extrem caution!

Usage example:

kubectl finalize namespace some-namespace --yes-i-really-mean-it
