I am always getting an error that PDO driver not found. I tried restarting, installing PDO extensions directly. Note that this docker setup works on my Linux box last night. Only difference is I did it from scratch compared to on my Windows box I already has images.
After getting the error initially I tried to remove the images, the base PHP image failed to remove for some reason. I then ran:
docker exec -it php shdocker-php-ext-install pdo pdo_mysql
Running that command explains that the extensions were already installed. But I still receive the error.
I also noticed this is present along with the modules:
/var/www/html # ls /usr/local/etc/php/conf.d/ docker-php-ext-pdo_mysql.ini /var/www/html # cat /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini extension=pdo_mysql.so DockerFile PHP

I did use to see the already installed message when I ran docker build but it still built the image fine for me.

Try building it from fresh using docker build --no-cache=true
