All configuration changes can be made using [`mc admin config` get/set/reset/export/import commands](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md).

#### List all config keys available

```
~ mc admin config set myminio/
```

#### Obtain help for each key

```
~ mc admin config set myminio/ <key>
```

e.g: `mc admin config set myminio/ etcd` returns available `etcd` config args

export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
minio server http://server{1...8}/mnt/hdd{1...16}
```

or

```sh
mc admin config set myminio/ api requests_max=1600
mc admin service restart myminio/
```

> NOTE: A zero value of `requests_max` means MinIO will automatically calculate requests based on available RAM size and that is the default behavior.

### Set a hard quota of 1GB for a bucket `mybucket` on MinIO object storage

```sh
mc admin bucket quota myminio/mybucket --hard 1gb
```

### Verify the quota configured on `mybucket` on MinIO

```sh
mc admin bucket quota myminio/mybucket
```

### Clear bucket quota configuration for `mybucket` on MinIO

```sh
mc admin bucket quota myminio/mybucket --clear

    $MC_COMMAND ;
    STATUS=$? ;
  done ;
  set -e ; # reset `e` as active
  return 0
}

# checkSvcacctExists ()
# Check if the svcacct exists, by using the exit code of `mc admin user svcacct info`
checkSvcacctExists() {
  CMD=$(${MC} admin user svcacct info myminio $(head -1 $MINIO_ACCESSKEY_SECRETKEY_TMP) > /dev/null 2>&1)
  return $?
}

# createSvcacct ($user)
createSvcacct () {
  USER=$1
  FILENAME=$2

    ca_file:   "./testdata/contrib/certs/root_ca_cert.pem"
    verify_and_map: true
}
authorization {
    ADMIN = {
        publish = ">"
        subscribe = ">"
    }
    users = [
        {user: "CN=localhost,OU=Client,O=MinIO,C=CA", permissions: $ADMIN}
    ]

MINIO_IDENTITY_OPENID_KEYCLOAK_ADMIN_URL    (string)    Specify Keycloak 'admin' REST API endpoint e.g. http://localhost:8080/auth/admin/
MINIO_IDENTITY_OPENID_REDIRECT_URI_DYNAMIC  (on|off)    Enable 'Host' header based dynamic redirect URI (default: 'off')

authenticate prometheus scrape requests, override the default Prometheus config with the one generated using mc. To generate a Prometheus config for an alias, use [mc](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) as follows `mc admin prometheus generate <alias> [METRIC-TYPE]`. The valid values for METRIC-TYPE are `cluster`, `node`, `bucket` and `resource` and if not mentioned, it defaults to `cluster`.

The command will generate the `scrape_configs` section of the prometheus.yml...

### 2. Create a new user with canned policy

Use [`mc admin policy`](https://min.io/docs/minio/linux/reference/minio-mc-admin/mc-admin-policy.html) to create canned policies. Server provides a default set of canned policies namely `writeonly`, `readonly` and `readwrite` *(these policies apply to all resources on the server)*. These can be overridden by custom policies using `mc admin policy` command.

The MinIO TLS STS API can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`). Further, it can be configured via the following environment variables:

```
mc admin config set myminio identity_tls --env
KEY:
identity_tls  enable X.509 TLS certificate SSO support

ARGS:

```
 mc admin tier add azure source AZURETIER --endpoint https://blob.core.windows.net --access-key AZURE_ACCOUNT_NAME --secret-key AZURE_ACCOUNT_KEY  --bucket azurebucket --prefix testprefix1/
```

> The admin user running this command needs the "admin:SetTier" and "admin:ListTier" permissions if not running as root.
