Abstract: The disclosure provides methods, apparatuses, and systems for downloading Docker images using a P2P distribution system. In one embodiment, a method comprises receiving, by a supernode from a client device, a download request for a layer of a container image file, the supernode selected from a supernode list comprising a plurality of supernodes; generating, by the supernode, slice information of each slice of the layer; and transmitting, by the supernode, the slice information and at least one target node to the client device, the transmitting of the slice information and the target node causing the client device to initiate a download of slices from the supernode to the at least one target node. By means of embodiments of the disclosure, the efficiency and stability of Docker image downloading can be improved.
