Processing JSON using jq

jq is useful to slice, filter, map and transform structured json data.

brew install jq

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

A common and reliable pattern in service unit files is thus:

NoNewPrivileges=yes
PrivateTmp=yes
PrivateDevices=yes
DevicePolicy=closed
ProtectSystem=strict

	user web;

	# One worker process per CPU core.
	worker_processes 8;

	# Also set
	# /etc/security/limits.conf
	# web soft nofile 65535
	# web hard nofile 65535
	# /etc/default/nginx

	#!/bin/sh

	#Check the Drive Space Used by Cached Files
	du -sh /var/cache/apt/archives

	#Clean all the log file
	#for logs in `find /var/log -type f`; do > $logs; done

	logs=`find /var/log -type f`
	for i in $logs

	# This script can keep the computer awake while executing another executable, or
	# if no executable was passed in, then it stays awake until this script stops.
	# There are 3 different ways of staying awake:
	# Away Mode - Enable away mode (https://blogs.msdn.microsoft.com/david_fleischman/2005/10/21/what-does-away-mode-do-anyway/)
	# Display Mode - Keep the display on and don't go to sleep or hibernation
	# System Mode - Don't go to sleep or hibernation
	# The default mode is the System Mode.
	# Away mode is only available when away mode is enabled in the advanced power options.
