UbuntuでDockerを使ったWordPress環境を作りたい

デスクトップUbuntuでWordPressの開発環境を作ろうと思っています。
見様見真似でDockerを使ってみようと思ったのですが

curl: (7) Failed to connect to localhost port 8000: 接続を拒否されました

と接続できずに困っています。ここからどう進めばいいのでしょうか？

#Docker-compose.yml

version: "2"
services:
  wordpress:
    image: wordpress:latest
    ports:
      - "8000:80"
    restart: always
    depends_on:
      - db
    environment:
      WORDPRESS_DB_HOST: db:3306
    env_file: .env
 db:
   image: mysql:latest
   env_file: .env
   volumes:
     - db-data:/var/lib/mysql

~/deb-wordpress以下にこのファイルをおいて

$sudo docker-compose up -d

をしています。

#環境
Ubuntu16.04
Docker version 1.12.6, build 78d1802
docker-compose version 1.15.0, build e12f3b

デスクトップUbuntuはVM等で構築した仮想環境ですか？

いえ、仮想環境では実行せず単独で動いています。

動作確認してみたので参考にどうぞ。

docker-compose.yml作成して実行

sh
1$ docker-compose up -d
2ERROR: yaml.parser.ParserError: while parsing a block mapping
3  in "./docker-compose.yml", line 1, column 1
4expected <block end>, but found '<block mapping start>'
5  in "./docker-compose.yml", line 13, column 2

字下げがおかしいので修正して実行
