 *
 * IMPORTANT NOTE:
 * This file may have been set to read-only by the Drupal installation program.
 * If you make changes to this file, be sure to protect it again after making
 * your modifications. Failure to remove write permissions to this file is a
 * security risk.
 *
 * In order to use the selection rules below the multisite aliasing file named
 * sites/sites.php must be present. Its optional settings will be loaded, and
 * the aliases in the array $sites will override the default directory rules
 * below. See sites/example.sites.php for more information about aliases.
 *
 * The configuration directory will be discovered by stripping the website's
 * hostname from left to right and pathname from right to left. The first
 * configuration file found will be used and any others will be ignored. If no
 * other configuration file is found then the default configuration file at
 * 'sites/default' will be used.
 *
 * For example, for a fictitious site installed at
 * https://www.drupal.org:8080/mysite/test/, the 'settings.php' file is searched
 * for in the following directories:
 *
 * - sites/8080.www.drupal.org.mysite.test
 * - sites/www.drupal.org.mysite.test
 * - sites/drupal.org.mysite.test
 * - sites/org.mysite.test

 *
 * - sites/8080.www.drupal.org
 * - sites/www.drupal.org
 * - sites/drupal.org
 * - sites/org
 *
 * - sites/default
 *
 * Note that if you are installing on a non-standard port number, prefix the
 * hostname with that number. For example,
 * https://www.drupal.org:8080/mysite/test/ could be loaded from
 * sites/8080.www.drupal.org.mysite.test/.
 *
 * @see example.sites.php
 * @see \Drupal\Core\DrupalKernel::getSitePath()
 *
 * In addition to customizing application settings through variables in
 * settings.php, you can create a services.yml file in the same directory to
 * register custom, site-specific service definitions and/or swap out default
 * implementations with custom ones.

/**
 * Database settings:
 *
 * The $databases array specifies the database connection or
 * connections that Drupal may use.  Drupal is able to connect
 * to multiple databases, including multiple types of databases,
 * during the same request.
 *
 * One example of the simplest connection array is shown below. To use the
 * sample settings, copy and uncomment the code below between the @code and
 * @endcode lines and paste it after the $databases declaration. You will need
 * to replace the database username and password and possibly the host and port
 * with the appropriate credentials for your database system.
 *
 * The next section describes how to customize the $databases array for more
 * specific needs.
 *
 * @code
 * $databases['default']['default'] = [
 *   'database' => 'databasename',
 *   'username' => 'sqlusername',
 *   'password' => 'sqlpassword',
 *   'host' => 'localhost',
 *   'port' => '3306',
 *   'driver' => 'mysql',
 *   'prefix' => '',
 *   'collation' => 'utf8mb4_general_ci',
 * ];
 * @endcode
 */
$databases['default']['default'] = array (
  'database' => getenv('MYSQL_DATABASE'),
  'username' => getenv('MYSQL_USER'),
  'password' => getenv('MYSQL_PASSWORD'),
  'prefix' => '',
  'host' => getenv('MYSQL_HOSTNAME'),
  'port' => getenv('MYSQL_PORT'),
  'namespace' => 'Drupal\\Core\\Database\\Driver\\mysql',
  'driver' => 'mysql',
);

/**
 * Customizing database settings.
 *
 * Many of the values of the $databases array can be customized for your
 * particular database system. Refer to the sample in the section above as a
 * starting point.
 *
 * The "driver" property indicates what Drupal database driver the
 * connection should use.  This is usually the same as the name of the
 * database type, such as mysql or sqlite, but not always.  The other
 * properties will vary depending on the driver.  For SQLite, you must
 * specify a database file name in a directory that is writable by the
 * webserver.  For most other drivers, you must specify a
 * username, password, host, and database name.
 *
 * Transaction support is enabled by default for all drivers that support it,
 * including MySQL. To explicitly disable it, set the 'transactions' key to
 * FALSE.
 * Note that some configurations of MySQL, such as the MyISAM engine, don't
 * support it and will proceed silently even if enabled. If you experience
 * transaction related crashes with such configuration, set the 'transactions'
 * key to FALSE.
 *
 * For each database, you may optionally specify multiple "target" databases.
 * A target database allows Drupal to try to send certain queries to a
 * different database if it can but fall back to the default connection if not.
 * That is useful for primary/replica replication, as Drupal may try to connect
 * to a replica server when appropriate and if one is not available will simply
 * fall back to the single primary server (The terms primary/replica are
 * traditionally referred to as master/slave in database server documentation).
 *
 * The general format for the $databases array is as follows:
 * @code
 * $databases['default']['default'] = $info_array;
 * $databases['default']['replica'][] = $info_array;
 * $databases['default']['replica'][] = $info_array;
 * $databases['extra']['default'] = $info_array;
 * @endcode
 *
 * In the above example, $info_array is an array of settings described above.
 * The first line sets a "default" database that has one primary database
 * (the second level default).  The second and third lines create an array
 * of potential replica databases.  Drupal will select one at random for a given
 * request as needed.  The fourth line creates a new database with a name of
 * "extra".
 *
 * You can optionally set prefixes for some or all database table names
 * by using the 'prefix' setting. If a prefix is specified, the table
 * name will be prepended with its value. Be sure to use valid database
 * characters only, usually alphanumeric and underscore. If no prefixes
 * are desired, leave it as an empty string ''.
 *
 * To have all database names prefixed, set 'prefix' as a string:
 * @code
 *   'prefix' => 'main_',
 * @endcode
 *
 * Per-table prefixes are deprecated as of Drupal 8.2, and will be removed in
 * Drupal 9.0. After that, only a single prefix for all tables will be
 * supported.
 *
 * To provide prefixes for specific tables, set 'prefix' as an array.
 * The array's keys are the table names and the values are the prefixes.
 * The 'default' element is mandatory and holds the prefix for any tables
 * not specified elsewhere in the array. Example:
 * @code
 *   'prefix' => [
 *     'default'   => 'main_',
 *     'users'     => 'shared_',
 *     'sessions'  => 'shared_',
 *     'role'      => 'shared_',
 *     'authmap'   => 'shared_',
 *   ],
 * @endcode
 * You can also use a reference to a schema/database as a prefix. This may be
 * useful if your Drupal installation exists in a schema that is not the default
 * or you want to access several databases from the same code base at the same
 * time.
 * Example:
 * @code
 *   'prefix' => [
 *     'default'   => 'main.',
 *     'users'     => 'shared.',
 *     'sessions'  => 'shared.',
 *     'role'      => 'shared.',
 *     'authmap'   => 'shared.',
 *   ];
 * @endcode
 * NOTE: MySQL and SQLite's definition of a schema is a database.
 *
 * Advanced users can add or override initial commands to execute when
 * connecting to the database server, as well as PDO connection settings. For
 * example, to enable MySQL SELECT queries to exceed the max_join_size system
 * variable, and to reduce the database connection timeout to 5 seconds:
 * @code
 * $databases['default']['default'] = [
 *   'init_commands' => [
 *     'big_selects' => 'SET SQL_BIG_SELECTS=1',
 *   ],
 *   'pdo' => [
 *     PDO::ATTR_TIMEOUT => 5,
 *   ],
 * ];
 * @endcode
 *
 * WARNING: The above defaults are designed for database portability. Changing
 * them may cause unexpected behavior, including potential data loss. See
 * https://www.drupal.org/developing/api/database/configuration for more
 * information on these defaults and the potential issues.
 *
 * More details can be found in the constructor methods for each driver:
 * - \Drupal\Core\Database\Driver\mysql\Connection::__construct()
 * - \Drupal\Core\Database\Driver\pgsql\Connection::__construct()
 * - \Drupal\Core\Database\Driver\sqlite\Connection::__construct()
 *
 * Sample Database configuration format for PostgreSQL (pgsql):
 * @code
 *   $databases['default']['default'] = [
 *     'driver' => 'pgsql',
 *     'database' => 'databasename',
 *     'username' => 'sqlusername',
 *     'password' => 'sqlpassword',
 *     'host' => 'localhost',
 *     'prefix' => '',
 *   ];
 * @endcode
 *
 * Sample Database configuration format for SQLite (sqlite):
 * @code
 *   $databases['default']['default'] = [
 *     'driver' => 'sqlite',
 *     'database' => '/path/to/databasefilename',
 *   ];
 * @endcode

/**
 * Reverse Proxy Configuration:
 *
 * Reverse proxy servers are often used to enhance the performance
 * of heavily visited sites and may also provide other site caching,
 * security, or encryption benefits. In an environment where Drupal
 * is behind a reverse proxy, the real IP address of the client should
 * be determined such that the correct client IP address is available
 * to Drupal's logging, statistics, and access management systems. In
 * the most simple scenario, the proxy server will add an
 * X-Forwarded-For header to the request that contains the client IP
 * address. However, HTTP headers are vulnerable to spoofing, where a
 * malicious client could bypass restrictions by setting the
 * X-Forwarded-For header directly. Therefore, Drupal's proxy
 * configuration requires the IP addresses of all remote proxies to be
 * specified in $settings['reverse_proxy_addresses'] to work correctly.
 *
 * Enable this setting to get Drupal to determine the client IP from the
 * X-Forwarded-For header. If you are unsure about this setting, do not have a
 * reverse proxy, or Drupal operates in a shared hosting environment, this
 * setting should remain commented out.
 *
 * In order for this setting to be used you must specify every possible
 * reverse proxy IP address in $settings['reverse_proxy_addresses'].
 * If a complete list of reverse proxies is not available in your
 * environment (for example, if you use a CDN) you may set the

 * Be aware, however, that it is likely that this would allow IP

 * Trusted host configuration.
 *
 * Drupal core can use the Symfony trusted host mechanism to prevent HTTP Host
 * header spoofing.
 *
 * To enable the trusted host mechanism, you enable your allowable hosts
 * in $settings['trusted_host_patterns']. This should be an array of regular
 * expression patterns, without delimiters, representing the hosts you would
 * like to allow.
 *
 * For example:
 * @code
 * $settings['trusted_host_patterns'] = [
 *   '^www\.example\.com$',
 * ];
 * @endcode
 * will allow the site to only run from www.example.com.
 *
 * If you are running multisite, or if you are running your site from
 * different domain names (eg, you don't redirect http://www.example.com to
 * http://example.com), you should specify all of the host patterns that are
 * allowed by your site.
 *
 * For example:
 * @code
 * getenv = [
 *   '^example\.com$',
 *   '^.+\.example\.com$',
 *   '^example\.org$',
 *   '^.+\.example\.org$',
 * ];
 * @endcode
 * will allow the site to run off of all variants of example.com and
 * example.org, with all subdomains included.
