# Einstellungen und Umgebungsvariablen { #settings-and-environment-variables }

In vielen Fällen benötigt Ihre Anwendung möglicherweise einige externe Einstellungen oder Konfigurationen, zum Beispiel geheime Schlüssel, Datenbank-Anmeldeinformationen, Anmeldeinformationen für E-Mail-Dienste, usw.

Die meisten dieser Einstellungen sind variabel (können sich ändern), wie z. B. Datenbank-URLs. Und vieles könnten schützenswerte, geheime Daten sein.

## Переменная окружения `PATH` { #path-environment-variable }

Существует **специальная** переменная окружения **`PATH`**, которая используется операционными системами (Linux, macOS, Windows) для поиска программ для запуска.

## Змінна оточення `PATH` { #path-environment-variable }

Є спеціальна змінна оточення `PATH`, яку використовують операційні системи (Linux, macOS, Windows) для пошуку програм для запуску.

   *
   * @param formal The type whose type variables or itself is mapped to other type(s). It's almost
   *     always a bug if {@code formal} isn't a type variable and contains no type variable. Make
   *     sure you are passing the two parameters in the right order.
   * @param actual The type that the formal type variable(s) are mapped to. It can be or contain yet

# Settings and Environment Variables { #settings-and-environment-variables }

In many cases your application could need some external settings or configurations, for example secret keys, database credentials, credentials for email services, etc.

Most of these settings are variable (can change), like database URLs. And many could be sensitive, like secrets.

For this reason it's common to provide them in environment variables that are read by the application.

     * <li>If <code>type</code> is a wildcard type, its (first) upper bound is returned.</li>
     * <li>If <code>type</code> is a type variable and is a key in the given map, its actual type argument is returned.</li>
     * <li>If <code>type</code> is a type variable and is not a key in the given map, its (first) upper bound is returned.</li>
     * <li>If <code>type</code> is an array, the actual class of its elements is returned.</li>

* `tuple`
* `set`
* `dict`

#### Liste { #list }

Definieren wir zum Beispiel eine Variable, die eine `list` von `str` – eine Liste von Strings – sein soll.

Deklarieren Sie die Variable mit der gleichen Doppelpunkt-Syntax (`:`).

Als Typ nehmen Sie `list`.

Da die Liste ein Typ ist, welcher innere Typen enthält, werden diese von eckigen Klammern umfasst:

export MINIO_IDENTITY_LDAP_TLS_SKIP_VERIFY=on
```

### Variable substitution in configuration strings

In the configuration variables, `%s` is substituted with the _username_ from the STS request and `%d` is substituted with the _distinguished username (user DN)_ of the LDAP user. Please see the following table for which configuration variables support these substitution variables:

| Variable                                    | Supported substitutions |
