php - Docker-compose 构建内存不足

问题描述

我正在尝试为具有以下功能的旧版应用程序构建 php-apache 容器：

实际 git 控制的项目被挂载到容器中
容器以主机用户身份运行（使用 uid 和 gid）以克服权限问题
该项目几乎没有相互连接的站点，因此我们开放了一些端口，以便更轻松地从主机访问它们。

这是 docker-compose.yml 文件：

version: '3.7'

services:
  db:
    env_file:
      - ./docker/docker.env
    build:
      context: .
      dockerfile: ./docker/mysql/Dockerfile
      network: host
    user: '74:74'
    ports:
      - "3307:3306"
    volumes:
      - ./docker/mysql/db_data:/var/lib/mysql
    restart: on-failure
  php:
    env_file:
      - ./docker/docker.env
    build:
      args:
        - USER_ID=${USER_ID}
        - GROUP_ID=${GROUP_ID_WWW}
        - USER=cakephp
        - PWD=password
        - HTTP_PROXY=${HTTP_PROXY}
        - HTTPS_PROXY=${HTTPS_PROXY}
      context: .
      dockerfile: ./docker/php/Dockerfile
      network: host
    depends_on:
      - db
    ports:
      - "9080:80"
      - "9081:80"
      - "9082:80"
      - "9083:80"
    volumes:
      - ./bakery:/var/www/html
      - ./bakery-assets:/var/www/assets
      - ./bakery-live:/var/www/local-live
      - ./bakery-preview:/var/www/local-preview
      - ./docker/apache/vhosts:/etc/apache2/sites-enabled
      - ./docker/php/tmp:/tmp/xdebug
    restart: on-failure
networks:
  hostnet:
    external: true
    name: host

这是 php 服务的 dockerfile：

尝试构建 php 服务时，空间不足，运行“docker system df”会返回如下输出：

TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE

我不明白 php 容器构建过程为什么会占用 295GB 甚至更多。是我的 Docker 构建过程有问题还是 docker 有问题。

我尝试运行 'docker system prune' 和 'docker volume prune' 并重新启动 docker，但结果总是这样。

我很感激这方面的帮助。谢谢。
