Docker compose 将WP-CLI容器添加到LEMP堆栈

我有一个工作的LEMP堆栈和下面的docker compose文件

Docker version 18.09.1, build 4c52b90
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS
Release:        18.04
Codename:       bionic

PHP映像的Dockerfile包含以下内容

version: "3.7"

services:
  php:
    build: 
      context: './config/php/'
    networks:
      - dev
    volumes:
      - /WORK/:/var/www/html/

    working_dir: /var/www/html/
    container_name: php

  nginx:
    image: nginx:1.14-alpine
    depends_on:
      - php
      - mysql
    networks:
      - dev      
    ports:
      - "80:80"
    volumes:
      - ./config/nginx/nginx.conf:/etc/nginx/conf.d/default.conf:ro
      - /WORK/:/var/www/html/
    container_name: nginx

  mysql:
    image: mysql:5.7
    restart: always
    ports:
      - "3306:3306"
    volumes:
      - /MYSQL/:/var/lib/mysql
    networks:
      - dev      
    environment:
      MYSQL_ROOT_PASSWORD: "db_root"
      MYSQL_DATABASE: "test_db"
      MYSQL_USER: "test_db_user"
      MYSQL_PASSWORD: "test_db_pass"
    container_name: mysql

  wpcli:
    image: wordpress:cli
    depends_on:
      - mysql
    environment:
      WORDPRESS_DB_HOST: mysql 
      WORDPRESS_DB_NAME: test_db
      WORDPRESS_DB_USER: test_db_user
      WORDPRESS_DB_PASSWORD: test_db_pass
    networks:
      - dev
    command: '--path=`/var/www/html/WP-Site/`'      
    volumes:
      - /WORK/:/var/www/html/
      - /MYSQL/:/var/lib/mysql
    working_dir: /var/www/html/
    container_name: wpcli

networks:
  dev:

NGINX配置是这样的

FROM php:7.2-fpm-alpine

# docker-entrypoint.sh dependencies
RUN apk add --no-cache \
# in theory, docker-entrypoint.sh is POSIX-compliant, but priority is a working, consistent image
        bash \
# BusyBox sed is not sufficient for some of our sed expressions
        sed

# https://github.com/docker-library/wordpress/blob/master/php7.3/fpm-alpine/Dockerfile
# install the PHP extensions we need
RUN set -ex; \
    \
    apk add --no-cache --virtual .build-deps \
        libjpeg-turbo-dev \
        libpng-dev \
        libzip-dev \
    ; \
    \
    docker-php-ext-configure gd --with-png-dir=/usr --with-jpeg-dir=/usr; \
    docker-php-ext-install gd mysqli opcache zip; \
    \
    runDeps="$( \
        scanelf --needed --nobanner --format '%n#p' --recursive /usr/local/lib/php/extensions \
            | tr ',' '\n' \
            | sort -u \
            | awk 'system("[ -e /usr/local/lib/" $1 " ]") == 0 { next } { print "so:" $1 }' \
    )"; \
    apk add --virtual .wordpress-phpexts-rundeps $runDeps; \
    apk del .build-deps

除WP-CLI之外的所有服务均正常工作。我的文件夹结构是这样的，在主

WORK

文件夹下我有子文件夹，每个子文件夹中都有一个项目

这样的项目可以是WordPress，但也可以使用另一个CMS，或者只是小型静态站点

在

http://localhost/

我看到了包含所有子文件夹的

工作

文件夹的概述。点击任何项目文件夹，例如

WP站点

，将引导我进入例如

http://localhost/WP-Site/

。在那里，我有一个可以正常工作的WordPress安装，它可以很好地连接到PHP和MYSQL服务

但是，当尝试使用WP-CLI时，它会告诉我找不到工作的WordPress安装，当我在服务中传递命令并为其提供我拥有的WordPress项目之一的路径时，它将在没有错误消息的情况下退出

我真的需要WordPress映像才能使用WP-CLI映像吗。在WP-CLI服务中，我还提供了与MYSQL服务相同的环境变量，以便WP-CLI可以知道连接到何处

如果有任何方法可以运行WP-CLI容器并将其放在主

WORK

文件夹下，那么对于我可能制作的所有项目，这将是非常好的

我本想把所有的东西都安装到一个图像中，但这样做违背了Docker的目的，即能够将东西分开并交换。所以我希望能够制作一个WP-CLI容器，它确实能够连接到我的PHP和MYSQL容器
