在 Docker compose 加上 log server 設定

希望將 docker compose logs -f 的訊息轉到 log server

針對 docker-compose.yml 內的每個服務設定 logging Exp.

  mariadb:
    image: mariadb
    container_name: db
    ports:
      - 3306:3306
    environment:
      - MARIADB_ROOT_PASSWORD=${MARIADB_ROOT_PASSWORD}
      - TZ=Asia/Taipei
    restart: always
    volumes:
      - ./db_data:/var/lib/mysql
    logging:
      driver: syslog
      options:
        syslog-address: "udp://192.168.11.230:514"
        syslog-facility: "local0"
        tag: "mariadb/{{.ID}}"
