#!/usr/bin/env bash
command -v docker >/dev/null 2>&1 || { echo >&2 "I require Docker but it's not installed. Aborting."; exit 1; }
echo "Basic auth for traefik >= v1.7"
read -p "User: " USER
read -p "Password: " PW
# Pull httpd:alpine image (small and includes httpasswd)
docker pull httpd:alpine >/dev/null 2>&1
# Generate strings
echo "------- Your string for configuration file (YAML/TOML) --------"
string=$(docker run --rm -i -t httpd:alpine htpasswd -nbB $USER $PW)
echo $string
echo "------- Your string for docker-compose.yml --------"
# Escape string
echo "$string" | sed -e 's/\$/\$\$/g'
