## Quickstart

To easily try out the feature, run the included demo Access Management Plugin program in this directory:

```sh
go run access-manager-plugin.go
```

This program, lets the admin user perform any action and prevents all other users from performing `s3:Put*` operations.

In another terminal start MinIO:

```sh
export MINIO_CI_CD=1

### Mehrere Prozesse – Ein Beispiel

Im folgenden Beispiel gibt es einen **Manager-Prozess**, welcher zwei **Workerprozesse** startet und steuert.

Dieser Manager-Prozess wäre wahrscheinlich derjenige, welcher der IP am **Port** lauscht. Und er würde die gesamte Kommunikation an die Workerprozesse weiterleiten.
