registry.yml

version: "3"

services:
  registry:
    restart: always
    image: registry:2
    ports:
      - 5000:5000
    volumes:
      - /data/docker/registry/storage:/var/lib/registry
      - /data/docker/registry/auth:/auth

setup.sh

#!/usr/bin/env bash

## Stop on errors:
set -e

## Get the username and password:
_USER="${1}"
_PASS="${2}"

## Check username and password:
if [ -z "${_USER}" ]; then
      echo "Username is not provided. Exiting..."
      exit 1
elif [ -z "${_PASS}" ]; then
      echo "Password is not provided. Exiting..."
      exit 1
fi

## Create required directories:
mkdir -p /data/docker/registry/{auth,storage}

## Update the password:
docker run --entrypoint htpasswd registry:2 -Bbn "${_USER}" "${_PASS}" > /data/docker/registry/auth/htpasswd

## Run the registry:
docker-compose -f registry.yml up -d
