Embodiment Construction

[0025] figure 1 It is a flow chart of the application migration method across kubernetes clusters in the embodiment of the present invention. The basic process of the method of the present invention is as follows:

[0026] S10: The original cluster exports the orchestration file of the application subject object.

[0027] Objects representing an application (workload) in Kubernetes mainly include: stateless application (Deployment), stateful application (StatefulSet), daemon process (DaemonSet), job (Job) and scheduled job (CronJob). When an application is running normally in the kubernetes cluster, you can obtain the configuration information of the application by viewing the yaml interface of the object. However, the configuration information obtained in this way usually includes information about the current cluster operation, such as the startup time of the application and specific information about the current environment. It usually fails to run such information direct...

Abstract

The invention relates to the technical field of application migration, in particular to an application migration method suitable for a cross-kubernetes cluster. The method comprises the following steps: 1, exporting an arrangement file of an application subject object by an original cluster; 2, extracting a dependent object according to the arrangement file of the application main body object, andexporting configuration information of the dependent object; 3, determining, by a new cluster, processing methods of all immigration objects, and forming a final configuration file and an immigrationsequence of the immigration objects; and 4, creating, by the new cluster, an immigration object and application external access information. According to the method, the problem that when the kubernetes cluster is migrated to another cluster, the yaml file of the application needs to be exported by using an original method for rearrangement is solved; and the method can be used for application migration across kubernetes clusters.

Description

technical field [0001] The invention relates to the technical field of application migration, in particular to an application migration method applicable to cross-kubernetes clusters. Background technique [0002] With the development and widespread popularity of Docker container technology, more and more applications are deployed using Docker. In order to make application deployment more convenient, the container orchestration technology represented by kubernetes has developed rapidly; major cloud vendors are gradually combining kubernetes with their own cloud services to support user application deployment. [0003] Native kubernetes application deployment has a relatively high threshold for users, and users must be familiar with the syntax of writing yaml layout files; therefore, third-party products (such as rancher) will package kubernetes to provide a graphical interface and convenient application store Users can quickly deploy applications through simple configuratio...
