使用Docker Compose部署NextCloud和WordPress

一、全局配置

name: lnmp
services:
  caddy:
    image: caddy:latest
    volumes:
      - ./www:/var/www/html
      - ./caddy/etc:/etc/caddy
      - ./caddy/data:/data
      - ./caddy/config:/config
    ports:
      - 80:80
      - 443:443/tcp
      - 443:443/udp
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: 3
    restart: always

  redis:
    image: redis:latest
    volumes:
      - ./redis/config:/etc/redis
      - ./redis/data:/data
    restart: always
    command: /etc/redis/redis.conf

  mysql:
    image: mysql:latest
    volumes:
      - ./mysql/config:/etc/mysql
      - ./mysql/data:/var/lib/mysql
      - ./mysql/mysql-files:/var/lib/mysql-files
    cap_add:
      - SYS_NICE
    security_opt:
      - seccomp:unconfined
    environment:
      MYSQL_ROOT_PASSWORD: password
    ports:
      - 3306:3306
    restart: always

  php:
    build: ./php
    volumes:
      - ./php/config:/usr/local/etc
      - ./php/logs:/var/log/php
      - ./www:/var/www/html
    depends_on:
      - caddy
      - mysql
      - redis
    cap_add:
      - SYS_PTRACE
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: 3
    restart: always

  imaginary:
    image: nextcloud/aio-imaginary:latest
    restart: always
    command: -concurrency 2 -enable-url-source
    environment:
      - PORT=9000

1. PHP

PHP官方的镜像启用和安装的扩展比较少，直接使用会导致WordPress和Nextcloud的健康检查一堆信息，所以使用Dockerfile来基于官方镜像构建一个专用的镜像，PHP需要的扩展包括:

• gd(png/jpeg/gif/webp/avif)
• imagick
• opcache(考虑性能)
• apcu(Nextcloud的本地缓存)
• zip(影响WordPress插件安装)
• redis(WordPress的对象缓存和Nextcloud的分布式缓存)
• gmp
• intl
