Retrieving Docker Image Sizes

There are two metrics that are important to consider when discussing the size of Docker images.

Compressed size - This is often referred to as the wire size. This affects how fast/slow images can be pulled from a registry. This impacts the first run experience on machines where images are not cached.
Uncompressed size - This is often referred to as the size on disk. This affects how much local storage is required to support your Docker workloads.

The example commands shown below will work on Windows, MacOS, and Linux.

Removes older versions

sudo rm -rf /usr/local/go* && sudo rm -rf /usr/local/go

	#! /bin/sh

	for num in `gh release list 2>/dev/null \| awk '{print $1}'`; do
	gh release delete $num -y
	done

	for num in `gh api repos/:owner/:repo/tags \| jq -r '.[].name'`; do
	gh api repos/:owner/:repo/git/refs/tags/${num} -X DELETE
	echo '✓ Deleted tag' $num
	done

	# ~/.zshrc file for zsh non-login shells.
	# see /usr/share/doc/zsh/examples/zshrc for examples

	setopt autocd # change directory just by typing its name
	#setopt correct # auto correct mistakes
	setopt interactivecomments # allow comments in interactive mode
	setopt ksharrays # arrays start at 0
	setopt magicequalsubst # enable filename expansion for arguments of the form ‘anything=expression’
	setopt nonomatch # hide error message if there is no match for the pattern
	setopt notify # report the status of background jobs immediately

	# Convert it into pkcs12 format
	openssl pkcs12 -export -out jenkins.p12 -inkey certificate.key -in certificate.crt -name "jenkins-cert"
