You can package an application in each container image without binding to the external basic environment, because the application does not require external dependencies to be more transparent than virtual machines, the depression monitoring management application is encapsulated in containers, and managing co

only local mirrors, never download　　　　ifnotpresent: Download the image only if it is not available locallyAfter the pod is assigned to node, it is mirrored and downloaded according to the image download policy, which can be used to determine the download strategy based on the characteristics of the cluster. Regardless of the strategy, make sure that the correct image is available on node.2.4 Other SettingsWith the Yaml file, you can set it in the pod
