P2P IMAGE DISTRIBUTION

1 . A computer-implemented method of pulling container images, the method comprising:

adding, by a processor, a new node to a multi-node cluster that includes worker nodes deployed across availability zones, wherein the new node is deployed in a first availability zone; and

pulling, by the processor, container images from a first subset of the worker nodes deployed in the first availability zone, and providing the container images to the new node.

2 . The method of claim 1 , wherein the container images are pulled concurrently to the new node.

3 . The method of claim 1 , wherein the processor is configured to pull the container images by:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.

4 . The method of claim 3 , wherein the spliced container images are pulled without performing compression on the spliced container images.

5 . The method of claim 1 , further comprising:

for the worker nodes not deployed in the first availability zone, pulling, by the processor, the container images from a second subset of the worker nodes deployed in a second availability zone closest to the first availability zone, from the availability zones.

6 . The method of claim 5 , wherein the processor is configured to pull the container images by:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.

7 . The method of claim 6 , wherein the spliced container images are pulled without performing compression on the spliced container images.

8 . A non-transitory computer readable medium, storing instructions for pulling container images, the instructions comprising:

adding a new node to a multi-node cluster that includes worker nodes deployed across availability zones, wherein the new node is deployed in a first availability zone; and

pulling container images from a first subset of the worker nodes deployed in the first availability zone, and providing the container images to the new node.

9 . The non-transitory computer readable medium of claim 8 , wherein the container images are pulled concurrently to the new node.

10 . The non-transitory computer readable medium of claim 8 , wherein the pulling container images comprises:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.

11 . The non-transitory computer readable medium of claim 10 , wherein the spliced container images are pulled without performing compression on the spliced container images.

12 . The non-transitory computer readable medium of claim 8 , further comprising:

for the worker nodes not deployed in the first availability zone, pulling the container images from a second subset of the worker nodes deployed in a second availability zone closest to the first availability zone, from the availability zones.

13 . The non-transitory computer readable medium of claim 12 , wherein the pulling container images comprises:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.

14 . The non-transitory computer readable medium of claim 13 , wherein the spliced container images are pulled without performing compression on the spliced container images.

15 . A system for pulling container images, the system comprising:

a multi-node cluster that includes worker nodes deployed across availability zones; and

a processor, wherein the processor is configured to:

add a new node to the multi-node cluster, wherein the new node is deployed in a first availability zone; and

pull container images from a first subset of the worker nodes deployed in the first availability zone, and providing the container images to the new node.

16 . The system of claim 15 , wherein the container images are pulled concurrently to the new node.

17 . The system of claim 15 , wherein the processor is configured to pull the container images by:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.

18 . The system of claim 17 , wherein the spliced container images are pulled without performing compression on the spliced container images.

19 . The system of claim 15 , further comprising:

for the worker nodes not deployed in the first availability zone, pulling, by the processor, the container images from a second subset of the worker nodes deployed in a second availability zone closest to the first availability zone, from the availability zones.

20 . The system of claim 19 , wherein the processor is configured to pull the container images by:

splitting each of the container images into corresponding spliced container images; and

pulling the spliced container images.
