Question

因此，在运行docker-compose up后，我在访问Error establishing a database connection时收到了http://localhost:8000/消息

docker ps -a的输出：

➜  ~ docker ps -a
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                    NAMES
5a3c015efeec        dockercompose_wordpress   "docker-php-entryp..."   17 minutes ago      Up 16 minutes       0.0.0.0:8000->80/tcp     dockercompose_wordpress_1
4e46c85345d5        dockercompose_db          "docker-entrypoint..."   17 minutes ago      Up 16 minutes       0.0.0.0:3306->3306/tcp   dockercompose_db_1

这是对的吗？或者它应该只显示一个容器wordpress depends_on db？

所以我希望在localhost:8000看到我的Wordpress网站已导入数据库，确保我sed更改所有网址以指向http://localhost 还将包含我的源文件的./html挂载到容器的/var/www/html。

我错过了什么吗？

文件夹结构：

| |-Dockerfile
| |-db.sql

|-html

搬运工-composer.yml ：

version: '3'

services:
  db:
    build:
      context: ./db
      args:
        MYSQL_DATABASE: coown 
        MYSQL_ROOT_PASSWORD: root
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: coown 
      MYSQL_ROOT_PASSWORD: root

  wordpress:
    build:
      context: ./php
    depends_on:
      - db
    ports:
      - "8000:80"
    volumes:
      - ./html:/var/www/html

分贝/ Dockerfile ：

FROM mysql:5.7
RUN chown -R mysql:root /var/lib/mysql/

ARG MYSQL_DATABASE
ARG MYSQL_ROOT_PASSWORD

ENV MYSQL_DATABASE=$MYSQL_DATABASE
ENV MYSQL_ROOT_PASSWORD=$MYSQL_ROOT_PASSWORD

ADD db.sql /etc/mysql/db.sql
RUN cp /etc/mysql/db.sql /docker-entrypoint-initdb.d

EXPOSE 3306

的PHP / Dockerfile ：

FROM php:7.0-apache
RUN docker-php-ext-install mysqli

docker-compose up 的一些输出：

Answer 1

您使用“db”主机将PHP（Wordpress？wp-config.php？）连接到您的数据库而不是通常的“localhost”？
