06-創建一個 wordpress 博客

有了前面的準備，後續服務就超級簡單了，比如我們現在要創建一個博客服務，只需要創建一個 blog 項目在 compose.yaml 中輸入下述 compose 設定

networks:
  ingress_intranet:
    external: true
services:
  db:
    image: ${IMAGE_OF_DB}
    restart: always
    environment:
      - TZ=Asia/Shanghai
      - MYSQL_ROOT_PASSWORD=123
      - MYSQL_DATABASE=wordpress
    volumes:
      - /opt/data/blog/mysql:/var/lib/mysql
  blog:
    image: ${IMAGE_OF_WORDPRESS}
    restart: always
    environment:
      - WORDPRESS_DB_HOST=db
      - WORDPRESS_DB_USER=root 
      - WORDPRESS_DB_PASSWORD=123
      - WORDPRESS_DB_NAME=wordpress
      - FORCE_SSL_ADMIN=false
    volumes:
      - /opt/data/blog/wordpress/plugins:/var/www/html/wp-content/plugins
      - /opt/data/blog/wordpress/themes:/var/www/html/wp-content/themes
      - /opt/data/blog/wordpress/uploads:/var/www/html/wp-content/uploads
    networks:
      default:
      ingress_intranet:
        ipv4_address: ${IP_OF_INGRESS}

.env 環境設定如下

IMAGE_OF_DB="mariadb:10.5.9"
IMAGE_OF_WORDPRESS="wordpress:6.1"

IP_OF_INGRESS="172.20.1.10"

執行 docker-compose -d 就部署好了：

1. services db 創建好了博客需要的數據庫
2. services blog 創建好了博客，記得去網關入口將域名反代到這個 service 的 80 端口

如此就又水一篇文章，docker compose 就是如此容易與簡單
