### Running an ACI with rkt

After it has been retrieved and stored locally, an ACI can be run by pointing [`rkt run`][rkt-run] at either the original image reference (in this case, `coreos.com/etcd:v2.3.7`), the ACI hash, or the full URL of the ACI. Therefore the following three examples are equivalent:
