我有magento运行在一个docker容器使用本教程（https://github.com/markshust/docker-magento）。
docker容器是通过https://magento.test访问的，在浏览器中可以正常工作。我们在magento中有一个脚本试图从容器中连接到https://magento.test，但Could not resolve host: magento.test失败。
基本上主机可以访问magento.test并连接到docker容器。但docker容器不能连接到自己。
我试过在docker-composer.yml中添加额外的主机（见下面），但是没有成功。我猜IP 127.0.0.1是不正确的。
