### 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 |

You can either use KES - together with an external KMS - or, much simpler,
set the env. variable `MINIO_KMS_SECRET_KEY` and start/restart the MinIO server. For more details about KES and how
to set it up refer to our [KMS Guide](https://github.com/minio/minio/blob/master/docs/kms/README.md).

Instead of configuring an external KMS you can start with a single key by
setting the env. variable `MINIO_KMS_SECRET_KEY`. It expects the following
format:

```sh

// decreasing precedence:
//
// 1. the value of the corresponding environment variable if set,
// 2. the value of the parameter in the config store if set,
// 3. the default value,
//
// This function only works for a subset of sub-systems, others return
// `ValueSourceAbsent`. FIXME: some parameters have custom environment
// variables for which support needs to be added.
//

mc admin service restart myminio
```

NOTE: `http://endpoint:port/path` is a placeholder value to indicate the URL format, please change this accordingly as per your configuration.

MinIO also honors environment variable for HTTP target logging as shown below, this setting will override the endpoint settings in the MinIO server config.

```
export MINIO_LOGGER_WEBHOOK_ENABLE_target1="on"
export MINIO_LOGGER_WEBHOOK_AUTH_TOKEN_target1="token"

| policy     | _string_ or _[]string_ or _comma_separated_value_ | Canned policy name to be applied for STS credentials. (Mandatory) - This can be configured to any desired value such as `roles` or `groups` by setting the environment variable `MINIO_IDENTITY_OPENID_CLAIM_NAME` |

## Get started

In this document we will explain in detail on how to configure all the prerequisites.

For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.

MINIO_POLICY_PLUGIN_COMMENT       (sentence)  optionally add a comment to this setting
```

By default this plugin uses HTTP 1.x. To enable HTTP2 use the `MINIO_POLICY_PLUGIN_ENABLE_HTTP2` environment variable.

## Request and Response

MinIO will make a `POST` request with a JSON body to the given plugin URL. If the auth token parameter is set, it will be sent as an authorization header.

			return newServerCfg()
		}
	}

	if !globalCredViaEnv && cfg.Credential.IsValid() {
		// Preserve older credential if we do not have
		// root credentials set via environment variable.
		globalActiveCred = cfg.Credential
	}

	// Init compression config. For future migration, Compression config needs to be copied over from previous version.
	switch cfg.Version {
	case "29":
		// V29 -> V30

```bash
~ mc admin config set myminio compression enable="on" extensions="" mime_types=""
```

The compression settings may also be set through environment variables.
When set, environment variables override the defined `compress` config settings in the server config.

```bash
export MINIO_COMPRESSION_ENABLE="on"
export MINIO_COMPRESSION_EXTENSIONS=".txt,.log,.csv,.json,.tar,.xml,.bin"
