Fatal error Incorrect DB config, or could not connect to DB PDOException: could not find driver

Hi All,

I am setting up the YOURLS, my environment is below
I created a docker image with

• php apache 8.0
• mysql
  After apply the config.php of YOURLS, it keeps saying
  "Fatal error Incorrect DB config, or could not connect to DB PDOException: could not find driver"

I have a simple PHP code to connect to the database, it works.
attached with the docker file, config.php and the index.php for your reference.
Much appreciated if anyone could provide me direction to proceed the installation

I fixed this error to add the PDO for mySQL driver
RUN docker-php-ext-install pdo pdo_mysql
