Dockerfile as a bash script

A simple experiment.

By creating bash functions for common Dockerfile commands (e.g., RUN, COPY) you can sort of implement docker build as a bash script.

It's sort of like a cheap buildah knockoff.

It creates the image example:build.bash

docwhat

#!/bin/bash
#
# Usage: ./run.bash $(sort --random-sort /usr/share/dict/words| head -n10 ) | tee /tmp/foo.html

set -euo pipefail

function string_to_color_hex {
    local -r string="$1"
    local -r hash=$(echo -n "$string" | md5sum | cut -d' ' -f1)
    local -ir r=$((16#${hash:0:2}))
