#container_all(filters = {}) ⇒ Object

filter options all – true or false, Show all containers. Only running containers are shown by default limit – Show limit last created containers, include non-running ones. since – Show only containers created since Id, include non-running ones. before – Show only containers created before Id, include non-running ones. size – true or false, Show the containers sizes
