This bash script addition looks for the REDIS_HOST and REDIS_PORT environment variables in the container. If they are present, it adds them to the wp-config.php in the form that the redis-cache plugin expects. It uses the wp-cli wp config command to alter the existing wp-config.php file.
It also checks for the existence of the redis-cache plugin. If present, the script activates it and uses the wp-cli interface of the plugin to create the object-cache.php file to enable the WordPress object cache.
If the environment variables and the plugin are not available, it will skip the cache setup.
