The embodiment of the invention provides an
image acquisition method in a node cluster, node equipment and a
server, and relates to the technical field of the information. The problem that a service container cannot operate as normal since the resource limitation of the existing service container cannot be used as normal under the situation that the used resource is unlimited when the existing
cluster node downloads an image through a P2P way by starting a BT
client is solved. The method comprises the following steps: a first node receives a service container operation request including an
image identifier of the image of a first to-be-operated service container and the resource limitation of the first to-be-operated service container, and requests mirror distribution information corresponding to the mirror identifier from the first
server; when an acquisition way of the
image layer comprises the P2P acquisition way, the first node creates a P2P container, and sets that the operation resource limitation of the P2P container to be less than and equal to the resource limitation of the first to-be-operated service container, and an
image layer compression sack corresponding to the
image layer identifier is acquired through the P2P container.
