protection bits added automatically to provide the regular safety for these objects up to 50% of the number of drives.
This will allow normal write operations to take place on systems that exceed the write tolerance.

	Novamente, apenas com a mesma declaração de tipo do Python, o **FastAPI** te dá de forma automática e interativa a documentação (integrada com o Swagger UI).

## Get started

### 1. Start OPA in a container

```sh
podman run -it \
    --name opa \
    --publish 8181:8181 \
    docker.io/openpolicyagent/opa:0.40.0-rootless \
       run --server \
           --log-format=json-pretty \
           --log-level=debug \
           --set=decision_logs.console=true
```

### 2. Create a sample OPA Policy

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  4096;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

# For Cygwin and MinGW, ensure paths are in Unix format before anything is touched
if $cygwin || $mingw ; then
  [ -n "$JAVA_HOME" ] &&
    JAVA_HOME=`cygpath --unix "$JAVA_HOME"`
fi

if [ -n "$JAVA_HOME" ] ; then
  if [ -x "$JAVA_HOME/jre/sh/java" ] ; then
    # IBM's JDK on AIX uses strange locations for the executables

  else
    JAVACMD="$JAVA_HOME/bin/java"

* `frozenset`:
    * Em requisições e respostas, será tratado da mesma forma que um `set`:
        * Nas requisições, uma lista será lida, eliminando duplicadas e convertendo-a em um `set`.
        * Nas respostas, o `set` será convertido para uma `list`.
