### 2. Create a sample OPA Policy

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
}

#!/usr/bin/env bash

# shellcheck disable=SC2120
exit_1() {
	cleanup

	echo "minio1 ============"
	cat /tmp/minio1_1.log
	echo "minio2 ============"
	cat /tmp/minio2_1.log
	echo "minio3 ============"
	cat /tmp/minio3_1.log

	exit 1
}

cleanup() {
	echo "Cleaning up instances of MinIO"
	pkill minio
	pkill -9 minio
	rm -rf /tmp/minio{1,2,3}
}

cleanup

unset MINIO_KMS_KES_CERT_FILE

	echo "BUG: expected no 'diff' after replication: $out"
	exit 1
fi

sitea_count=$(cat /tmp/sitea_dirs.txt | wc -l) # need to do it this way to avoid filename in the output
siteb_count=$(cat /tmp/siteb_dirs.txt | wc -l) # need to do it this way to avoid filename in the output
sitea_out=$(cat /tmp/sitea_dirs.txt)
siteb_out=$(cat /tmp/siteb_dirs.txt)

if [ $sitea_count -ne 0 ]; then

Zum Beispiel:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In diesem Fall ist `fluffy` eine Instanz der Klasse `Cat`.

Und um `fluffy` zu erzeugen, rufen Sie `Cat` auf.

Eine Python-Klasse ist also auch ein **Callable**.

#!/usr/bin/env bash

# shellcheck disable=SC2120
exit_1() {
	cleanup

	echo "minio1 ============"
	cat /tmp/minio1_1.log
	echo "minio2 ============"
	cat /tmp/minio2_1.log
	echo "minio3 ============"
	cat /tmp/minio3_1.log
	echo "minio4 ============"
	cat /tmp/minio4_1.log
	exit 1
}

cleanup() {
	echo -n "Cleaning up instances of MinIO ..."
	pkill -9 minio || sudo pkill -9 minio
	pkill -9 kes || sudo pkill -9 kes

# Use a check-sleep-check loop to wait for MinIO service to be available
connectToMinio() {
	SCHEME=$1
	ATTEMPTS=0
	LIMIT=29 # Allow 30 attempts
	set -e   # fail if we can't read the keys.
	ACCESS=$(cat /config/rootUser)
	SECRET=$(cat /config/rootPassword)
	set +e # The connections to minio are allowed to fail.
	echo "Connecting to MinIO server: $SCHEME://$MINIO_ENDPOINT:$MINIO_PORT"

これを「呼び出し可能」なものと呼びます。

## 依存関係としてのクラス

Pythonのクラスのインスタンスを作成する際に、同じ構文を使用していることに気づくかもしれません。

例えば:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

この場合、`fluffy`は`Cat`クラスのインスタンスです。

そして`fluffy`を作成するために、`Cat`を「呼び出している」ことになります。

そのため、Pythonのクラスもまた「呼び出し可能」です。

そして、**FastAPI** では、Pythonのクラスを依存関係として使用することができます。
