メモ的な記事です。
全然動くyamlが乗ってなかったので、書きました。

docker-compose.yml

version: '3'

services:

  mongo:
    image: mongo
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: MongoDB2019!
    ports:
      - 27017:27017
    volumes:
      - ./db:/data/db

  mongo-express:
    image: mongo-express
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_BASICAUTH_USERNAME: admin
      ME_CONFIG_BASICAUTH_PASSWORD: password
      ME_CONFIG_MONGODB_PORT: 27017
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: MongoDB2019!
    depends_on:
      - mongo

とりあえず、現時点での最低構成はこんな感じです。
これを書いてdocker-compose upして、http://localhost:8081か、もしくはローカルネットワーク上のサーバーで建てているのなら、http://192.168.0.25:8081のように接続すれば画像↓のようなコントロールパネルが出るかと思います。

一応起動ログを貼っておきます。dc upはdocker-compose upのaliasです。
