The embodiment of the invention discloses a method and device for clearing a mirror image in a cluster node, and is applied to the cluster node. The method comprises the following steps: when a target application deployed on the cluster node of a server is upgraded, recording the name of the newly downloaded mirror image used for upgrading, the current latest version information of the mirror image, and the version information of the previous old version mirror image of the current latest version; when the task of clearing the mirror image is executed, keeping the current latest version mirror image and the previous old version mirror image of the current latest version in all the found locally stored mirror images according to the currently recorded name of the mirror image, the latest version information, and the version information of the previous old version mirror image of the current latest version, and clearing the mirror images of the other versions. By using the method provided by the embodiment of the invention, the probability of deleting by accident the mirror image probably reused in the future is reduced.
Description
technical field [0001] The invention relates to the technical field of information processing of server clusters, in particular to a method and device for clearing images in cluster nodes. Background technique [0002] In today's information age, the Internet has developed rapidly and provided many conveniences for people's production and life, and people are increasingly using the Internet to obtain corresponding services. [0003] Currently, server clusters use Docker containers extensively to run applications and provide services. The application scheduling server will deploy the application to each cluster node of the server cluster. Specifically, the scheduling server selects some cluster nodes according to the application configuration information, and notifies these cluster nodes to go to the image warehouse server to download the image corresponding to the image version information in the application configuration information, and use this version image to create an...
