为laravel Project运行docker-compose up -d时遇到错误。

ERROR: for groshop_laravel-env_1  Cannot start service laravel-env: OCI runtime create failed: container_linux.go:370: starting container process caused: exec: "php-fpm": executable file not found in $PATH: unknown

我也有在配置下的PHP文件。尝试了CMD更改，但没有运气。任何想法？我还看到的另一项观察结果是，我看不到/ etc下的那些php-fpm。*文件，但仅看到下面内容的supervisord.conf文件。
