Docker compose 编写器未通过dockerfile安装wordpress插件

我正在使用docker compose构建wordpress环境。我的计划是使用composer安装我需要的插件和主题。当我运行docker compose build时，一切都很好，没有问题。当我运行docker compose up时，我看到所有容器都在运行，包括composer。当我导航到wordpress构建时，只安装了默认主题和插件。我的问题是为什么没有安装我的插件和主题。我错过了什么

我试着把我认为相关的文件包括进去

文件结构

composer.json

Dockerfile作曲家

Dockerfile Wodrpess

Dockerfile数据库

docker-compose.yml

正如我在评论中解释的，你需要重新安排一下你的项目

composer文件夹和服务可能会消失。将文件夹生成器的内容移动到wordpress文件夹中

wordpress文件夹中的Dockerfile应该如下所示：

FROM composer/composer:php7 as build

# Install composer
WORKDIR /var/www/html/wp-content

RUN curl -sS https://getcomposer.org/installer | \
    php -- --install-dir=/usr/bin/ --filename=composer

COPY composer.json /var/www/html/wp-content
# COPY composer.lock ./
RUN composer install --no-scripts --no-autoloader
# COPY ./ /var/www/
RUN composer dump-autoload --optimize

FROM wordpress:5.1.1-php7.3-apache

# Set our environment variables for logging into wordpress
ENV WORDPRESS_DB_HOST database:3306
ENV WORDPRESS_DB_USER username
ENV WORDPRESS_DB_PASSWORD password

COPY --from=build /var/www/html/wp-content /var/www/html/wp-content

# Expose a port to run on
EXPOSE 80

version: "3.3"
services:
  wordpress:
    build:
      context: ./config/docker/wordpress
    ports:
      - "8080:80"
    restart: always
    working_dir: /var/www/html
    depends_on:
      - database
  database:
    build:
      context: ./config/docker/database
    volumes:
      - datab:/var/lib/mysql
    restart: always
  phpmyadmin:
    build:
        context: ./config/docker/phpmyadmin
    ports:
      - 8181:80
    restart: always
    depends_on:
      - database
volumes:
    datab: {}

docker-compose.yml现在可以简化为：

FROM composer/composer:php7 as build

# Install composer
WORKDIR /var/www/html/wp-content

RUN curl -sS https://getcomposer.org/installer | \
    php -- --install-dir=/usr/bin/ --filename=composer

COPY composer.json /var/www/html/wp-content
# COPY composer.lock ./
RUN composer install --no-scripts --no-autoloader
# COPY ./ /var/www/
RUN composer dump-autoload --optimize

FROM wordpress:5.1.1-php7.3-apache

# Set our environment variables for logging into wordpress
ENV WORDPRESS_DB_HOST database:3306
ENV WORDPRESS_DB_USER username
ENV WORDPRESS_DB_PASSWORD password

COPY --from=build /var/www/html/wp-content /var/www/html/wp-content

# Expose a port to run on
EXPOSE 80

version: "3.3"
services:
  wordpress:
    build:
      context: ./config/docker/wordpress
    ports:
      - "8080:80"
    restart: always
    working_dir: /var/www/html
    depends_on:
      - database
  database:
    build:
      context: ./config/docker/database
    volumes:
      - datab:/var/lib/mysql
    restart: always
  phpmyadmin:
    build:
        context: ./config/docker/phpmyadmin
    ports:
      - 8181:80
    restart: always
    depends_on:
      - database
volumes:
    datab: {}

我希望这对你有用。否则，请告诉我错误，我会查看它。

composer服务实际上不需要运行，因为它在构建期间完成了所有工作。在构建时，您在docker compose中执行的卷映射不可用。我建议对wordpress服务使用多阶段构建：第一阶段应该是撰写dockerfile的撰写部分，第二阶段应该将/var/www/html/wp内容复制到wordpress图像中，并继续在wordpress dockerfile中进行任何工作。Hi@Mihai感谢您的回复。你有没有这样的例子？我从docker compose文件中删除了composer服务。首先，我运行了composer docker文件来安装composer，但第二部分我对复制的内容感到困惑。谢谢你的帮助好的，你能发布你正在使用的wordpress Dockerfile吗？我已经用wordpress和数据库Dockerfile更新了我的问题非常感谢你的例子。这对我有用！
