我正在尝试使用这个简单的示例链接 Amazon ECS（容器服务）中的两个容器：http: //docs.aws.amazon.com/AmazonECS/latest/developerguide/example_task_definitions.html
无论出于何种原因，WordPress 容器无法访问 MySQL 数据库，并且从 WordPress 容器的日志中我看到以下内容：
Warning: mysqli::mysqli(): (HY000/2002): Connection refused in - on line 10
在DockerHub上说 WordPress 容器会自动从链接的容器中获取 Root PW 和 HOST IP，所以我为什么会遇到这个问题。
我的 JSON 配置如下所示：
