Method, server, and system for image deployment

A server, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory has instructions stored therein, and the instructions, when executed by the processor, cause the server to perform actions comprising:
• receiving requests for pulling images from a plurality of nodes, wherein an image requested to be pulled by a first node is a first image;
• detecting that layers of a plurality of images requested to be pulled by the plurality of nodes all comprise a common layer;
• generating a transmission path of data of the common layer, wherein the transmission path comprises transmitting the data of the common layer to a second node, the second node being an initial node selected in the plurality of nodes for distributing the data of the common layer to other nodes;
• sending setting information to the first node according to the transmission path, wherein the setting information comprises instructing the first node to acquire the data of the common layer from a third node;
• and
• sending the data of the common layer to the second node, wherein the first node acquires the data of the common layer from the third node according to the setting information.

A computer program product that is tangibly stored on a non-transitory computer-readable medium and comprises machine-executable instructions, wherein the machine-executable instructions, when executed by a machine, cause the machine to perform a method for image deployment, the method comprising:

• receiving requests for pulling images from a plurality of nodes, wherein an image requested to be pulled by a first node is a first image;
• detecting that layers of a plurality of images requested to be pulled by the plurality of nodes all comprise a common layer;
• generating a transmission path of data of the common layer, wherein the transmission path comprises transmitting the data of the common layer to a second node, the second node being an initial node selected in the plurality of nodes for distributing the data of the common layer to other nodes;
• sending setting information to the first node according to the transmission path, wherein the setting information comprises instructing the first node to acquire the data of the common layer from a third node;
• and
• sending the data of the common layer to the second node, wherein the first node acquires the data of the common layer from the third node according to the setting information.
