我正在尝试使php在正式的nginx高山linux docker映像nginx:alpine上运行。在容器的入口点，我正在运行一个脚本，该脚本执行以下操作：
rc-service -v php-fpm7 restart && nginx-debug -g "daemon off;"
但是高山linux继续显示
警告：php-fpm7已经开始
我也尝试过先在容器rc-service -v php-fpm7 stop内执行，然后在rc-service -v php-fpm7 start内执行，但是我得到了几乎相同的错误：
错误：php-fpm7被别的东西停止了
警告：php-fpm7已经开始
随机执行几次后，我得到：

* You are attempting to run an openrc service on a
* system which openrc did not boot.
* You may be inside a chroot or you may have used
* another initialization system to boot this system.
* In this situation, you will get unpredictable results!
* If you really want to do this, issue the following command:
* touch /run/openrc/softlevel
* ERROR: networking failed to start
* ERROR: cannot start php-fpm7 as networking would not start
我们将不胜感激。
