Description:

The Docker container for the project doesn't create the SQLite database as expected. Upon startup, the container runs a sed command to modify the telemetry_settings.php file, but this change doesn't align with the actual configuration line in the file. As a result, the SQLite database isn't created.

Steps to Reproduce:

1. Run the Docker container for the librespeed/speedtest project.
2. Observe the startup logs.
3. Note that the sed command modifies the $Sqlite_db_file variable in telemetry_settings.php.
4. Check the telemetry_settings.php file configuration for $Sqlite_db_file.
5. Notice that the sed command does not match the line in the config.

Expected Behavior:

The sed command should properly update the $Sqlite_db_file variable to ensure the database is created at the correct location (/database/db.sql).

Actual Behavior:

The sed command attempts to replace the $Sqlite_db_file path, but the existing configuration in telemetry_settings.php is as follows:

// Sqlite3 settings  
$Sqlite_db_file = __DIR__ . '/../../speedtest_telemetry.db';

This mismatch prevents the database from being created at the correct location.

Possible Cause:

The sed command executed at container startup is:

sed -i 's/$Sqlite_db_file = '\''.*'\''/$Sqlite_db_file='\''\/database\/db.sql'\''/g' /var/www/html/results/telemetry_settings.php

This command tries to replace the $Sqlite_db_file value, but it doesn't account for the exact structure of the current line:

$Sqlite_db_file = __DIR__ . '/../../speedtest_telemetry.db';

Therefore, the database path isn't updated properly, leading to the failure of database creation.
