The invention discloses a distributed container cluster mirror image management master node, slave nodes, a system and a method, wherein the main node comprises a mirror image database which is a distributed database and is used for storing node information of all nodes in the system; the request input module is used for receiving request content including a request target and command execution content; mirror image management module, the verification module is used for communicating the password and verifying whether the request content acquired by the request record input module is legal; ifit is judged that a request target in the request content is a specified single slave node or grouped slave nodes, sending a communication password and command execution content including a pulling operation, an updating operation, a deleting operation and a cleaning operation to IP addresses corresponding to the slave nodes; and receiving the state feedback content sent by the slave node. According to the invention, the flattening management of the container cluster mirror image is realized, the management efficiency of the cluster container mirror image in a distributed system is improved,and the high reliability and safety of the whole cluster are improved.
