### 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 {

	authzBuilder := lb.authzBuilder
	if policySvc != nil {
		useFilterState := lb.node.Type == model.Waypoint
		authzBuilder = authz.NewBuilderForService(authz.Local, lb.push, lb.node, useFilterState, policySvc)
		authzCustomBuilder = authz.NewBuilderForService(authz.Custom, lb.push, lb.node, useFilterState, policySvc)
	}
