In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

# All other users may do anything other than call PutObject
allow {
 input.action != "s3:PutObject"

MinIO now includes support for using an Access Management Plugin. This is to allow object storage access control to be managed externally via a webhook.

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.

```
$ go run docs/sts/web-identity.go -cid account -csec 072e7f00-4289-469c-9ab2-bbe843c7f5a8  -config-ep "http://CASDOOR_ENDPOINT/.well-known/openid-configuration" -port 8888

## Concepts

- All Buckets on MinIO are always in one of the following states: unversioned (the default) and all other existing deployments, versioning-enabled, or versioning-suspended.

## Features

- A pool in decommission still allows READ access to all its contents, newer WRITEs will automatically be scheduled to only pools not in decommission status.

be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

#### MINIO_DOMAIN

This is the top level domain name used for the federated setup. This domain name should ideally resolve to a load-balancer
running in front of all the federated MinIO instances. The domain name is used to create sub domain entries to etcd. For

  "http://localhost:8080/auth/admin/realms/{realm}/users/{userid}"
```

### Configure MinIO

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
minio server /mnt/export
```

Here are all the available options to configure OpenID connect

```
mc admin config set myminio/ identity_openid

KEY:
identity_openid  enable OpenID SSO support

ARGS:

```

MinIO supports all the exchanges available in [RabbitMQ](https://www.rabbitmq.com/). For this setup, we are using `fanout` exchange.

from flask import Flask, request, abort, make_response
import requests

app = Flask(__name__)
@app.route('/', methods=['POST'])
def get_webhook():
	if request.method == 'POST':
		# obtain the request event from the 'POST' call
		event = request.json

		object_context = event["getObjectContext"]

		# Get the presigned URL to fetch the requested
		# original object from MinIO
		s3_url = object_context["inputS3Url"]

> [!NOTE]
> To enable compression for all content when using environment variables, set either or both of the extensions and MIME types to `*` instead of an empty string:
> ```bash
> export MINIO_COMPRESSION_ENABLE="on"
> export MINIO_COMPRESSION_EXTENSIONS="*"
> export MINIO_COMPRESSION_MIME_TYPES="*"
> ```

### 3. Compression + Encryption

Combining encryption and compression is not safe in all setups.
