How docker modify php. ini?

Today, I changed to the Deepin operating system. The development environment was built through Docker. The specific structure is as follows:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
ef6fadf6ebf0        nginx               "nginx -g 'daemon of…"   19 hours ago        Up 2 hours          0.0.0.0:8080->80/tcp     nginx
edb6bc0ad5bc        php:7.1-fpm         "docker-php-entrypoi…"   19 hours ago        Up 2 hours          0.0.0.0:9000->9000/tcp   php7.1
c77df990721e        mysql:5.6           "docker-entrypoint.s…"   23 hours ago        Up 3 hours          0.0.0.0:3306->3306/tcp   mysql5.6

The php container is installed through the following command:

docker pull php:7.1-fpm

Now we need to upload files in the project, but the php upload configuration provided by the mirror is:

upload_max_filesize=2M
post_max_size=2M

is obviously insufficient, so we need to modify the configuration file, but after searching for a long time, I couldn’t find php.ini Where is the configuration file? Finally, you can do this:

cd /usr/local/etc/php/conf.d
 
vi upload.ini

Enter the following content:

upload_max_filesize=100M
post_max_size=100M

In this way, the configuration is completed. Why is this okay? Because the ini configuration file under the /usr/local/etc/php/conf.d directory will be loaded automatically.
