本地主机上的 docker - wordpress cron 问题 - 无法连接到 local.domain 端口 80：连接被拒绝

Question

我使用了一组 docker 图像在本地主机上运行 wordpress：https://github.com/wodby/docker4wordpress 当我从 php 文件或从 php 容器运行这个工具时，我遇到了 cURL 命令的问题。 cURL 仅在我从 nginx 命令行运行时才有效。 如何配置 docker-compose 运行 cURL 并修复 wordpress cron。 我的配置：

docker-compose

version: "3"

services:
  mariadb:
    image: wodby/mariadb:$MARIADB_TAG
    container_name: "${PROJECT_NAME}_mariadb"

      MYSQL_DATABASE: $DB_NAME

    volumes:
#    - ./mariadb-init:/docker-entrypoint-initdb.d # Place init .sql file(s) here.
    - ./db:/var/lib/mysql # I want to manage volumes manually.
