### 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
}

// SYSREG_END is the last item in the automatically generated system register
// declaration, and it is defined in the sysRegEnc.go file.
// Define the special register after REG_SPECIAL, the first value of it should be
// REG_{name} = SYSREG_END + iota.
const (
	REG_SPECIAL = obj.RBaseARM64 + 1<<12
)

// Register assignments:
//
// compiler allocates R0 up as temps
// compiler allocates register variables R7-R25

// by the CPU correctly.
