### 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
}

# All other users may do anything other than call PutObject
allow {
