How does a Docker container always run in the background using PHP-FPM?

On the basis of the official centos started a container, installed in the PHP-FPM. now I want this container to run in the background, and another container (such as the NGINX server container) is connected to its PHP-FPM service. The following is my startup parameter: {code ...} {code ...} the container does not seem to be... on the basis of the official centos started a container, installed in the PHP-FPM.

The following are my startup parameters:

# Test/php is the image name docker-d -- name php-fpm test/php/usr/sbin/php-fpm

docker -d --name php-fpm test/php /usr/sbin/php-fpm -D #daemonize

In the container, it seems that php-fpm cannot be started through the service.

[root@5233bbc57e72 /]# systemctl start php-fpmFailed to get D-Bus connection: No connection to service manager.

So install a supervisor.

Start

docker run -d test/php /usr/bin/supervisord

If the container can be maintained in the background, but php-fpm is not started!
The configuration of php-fpm is default.
