laravel redis best practice

say:

Before using Redis with Laravel, we encorage you to install and use the PhpRedis PHP extension via PECL. The extension is more complex to install but may yield better performance for applications that make heavy use of Redis. Predis has been abandoned by the package's original author and may be removed from Laravel in a future release.

so we should use PhpRedis not predis. try this:

apt install php-redis

it's fine on local Ubuntu, but faild in Docker "php:7.3-apache", error:

root@b7aea273ec31:/var/www/laravel# apt search php-redis

This may mean that the package is missing, has been obsoleted, or
is only available from another source
