> **NOTE:** `{1...n}` shown have 3 dots! Using only 2 dots `{1..n}` will be interpreted by your shell and won't be passed to MinIO server, affecting the erasure coding order, which would impact performance and high availability. **Always use ellipses syntax `{1...n}` (3 dots!) for optimal erasure-code distribution**

Environment variables could be useful for handling application **settings**, as part of the **installation** of Python, etc.

## Create and Use Env Vars { #create-and-use-env-vars }

You can **create** and use environment variables in the **shell (terminal)**, without needing Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"

GraalVM Native Image
--------------------

Building your native images with [GraalVM] should work automatically.

See the okcurl module for an example build.

```shell
$ ./gradlew okcurl:nativeImage
$ ./okcurl/build/graal/okcurl https://httpbin.org/get
```

Java Modules
------------

OkHttp (5.2+) implements Java 9 Modules.

Puedes leer más sobre esto en las <a href="https://docs.docker.com/reference/dockerfile/#shell-and-exec-form" class="external-link" target="_blank">documentación de Docker para formas de shell y exec</a>.

```

⛔️ **Shell**-форма:

```Dockerfile
# ⛔️ Не делайте так
CMD fastapi run app/main.py --port 80
```

Обязательно используйте **exec**-форму, чтобы FastAPI мог корректно завершаться и чтобы срабатывали [события lifespan](../advanced/events.md){.internal-link target=_blank}.

For example:
```shell
group_search_filter: (&(objectClass=group)(member:1.2.840.113556.1.4.1941:=%d))
user_dn_search_filter: (&(memberOf:1.2.840.113556.1.4.1941:=CN=group,DC=dc,DC=net)(sAMAccountName=%s))
```

### Sample settings

Here are some (minimal) sample settings for development or experimentation:

```shell
export MINIO_IDENTITY_LDAP_SERVER_ADDR=myldapserver.com:636

	if err != nil {
		if legacyCredentials {
			logger.Fatal(config.ErrInvalidCredentials(err),
				"Unable to validate credentials inherited from the shell environment")
		} else {
			logger.Fatal(config.ErrInvalidRootUserCredentials(err),
				"Unable to validate credentials inherited from the shell environment")
		}
	}
	if env.IsSet(config.EnvAccessKey) && env.IsSet(config.EnvSecretKey) {
