Docker-Compose：“在此目录或任何父目录中找不到合适的配置文件”

Question

在使用 docker pull ajitgoel/socialmediascrubber 命令从 docker 拉取图像后，我正在尝试使用 docker-compose build 命令运行应用程序。 然而，我得到了一个

Can't find a suitable configuration file in this directory or any parent. Are you in the right directory?

错误。运行ls | grep *compose.yml 也不会返回任何结果。 我错过了什么？

当找不到docker-compose.yml 文件时，您看到的错误是docker-compose 错误。

不确定为什么要显示 ls 输出 - 但如果它是您正在运行的同一文件夹的输出，那么您也可以看到没有 docker-compose.yml 文件。

在运行任何docker-compose 命令之前无需执行docker pull。
