Technical Field

Background

The k8s cluster migration is a common requirement scenario in PaaS cloud operation and maintenance, and under scenarios such as infrastructure change, k8s upgrade, and technology architecture transformation, there is a requirement for k8s cluster migration. Generally, k8s cluster migration refers primarily to the re-creation of k8s resources in a source cluster in a target cluster. Besides migration of k8s resources, the migration of cluster traffic is also important, and in an actual migration scenario, the shorter the service interruption time brought to the service by migration of an application is, the better.

The existing k8s cluster migration technical scheme is mostly based on cluster resource redeployment, that is, cluster resources are redeployed in a target cluster according to the original deployment mode of the k8s resources of a source cluster. The technical scheme generally needs to comb resource lists and attributions of a source cluster k8s, comb k8s resource creation logic, make and integrate migration schemes of k8s resources, make and integrate emergency rollback schemes of k8s resource migration and other steps.

The k8s cluster migration technical scheme based on cluster resource redeployment has the defects of low automation degree, long closed loop, poor universality and the like. The core idea of the scheme is to execute the original steps of cluster resource deployment in the target cluster to achieve the effect of cluster migration, but since the k8s cluster is an infrastructure shared by multiple users, the migration and rollback schemes need to be provided by the users, and the cloud platform operation and maintenance personnel are integrated, so that the migration uncertainty is increased. In addition, because the resources deployed by each cluster are different and the related applications are different, the migration scheme is different according to different clusters, and the universality is poor. Finally, the migration of the cluster traffic is not considered, which may cause the interruption of the external service of the application in the cluster migration process.

Aiming at the problem that resources in a cluster cannot be subjected to hot migration in the related art, an effective solution is not provided at present.

For example, an interface is provided between the system and the relevant user or organization, before obtaining the relevant information, an obtaining request needs to be sent to the user or organization through the interface, and after receiving the consent information fed back by the user or organization, the relevant information is obtained.

The present invention is described below with reference to preferred implementation steps, and fig. 1 is a flowchart of a resource migration method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step S102, acquiring a migration request for migrating a plurality of resources to be migrated in an original cluster;

step S104, responding to the migration request, and executing the operation of migrating a plurality of resources to be migrated in the original cluster to the target cluster;

step S106, in the process of migrating a plurality of resources to be migrated in an original cluster to a target cluster, if it is detected that a target resource capable of providing external services exists in the target cluster, determining migration information of the target resource, wherein the plurality of resources to be migrated include the target resource, and the migration information is used for indicating the migration progress of the target resource relative to the plurality of resources to be migrated;

and step S108, migrating the request traffic of the original cluster to the target cluster according to the migration information, wherein the request traffic is served by the target resource.

Through the application, the following steps are adopted: acquiring a migration request for migrating a plurality of resources to be migrated in an original cluster; responding to the migration request, and executing the operation of migrating a plurality of resources to be migrated in the original cluster to the target cluster; in the process of migrating a plurality of resources to be migrated in an original cluster to a target cluster, if it is detected that a target resource capable of providing external services exists in the target cluster, determining migration information of the target resource, wherein the migration information is used for indicating migration progress of the target resource relative to the plurality of resources to be migrated; and migrating the request traffic of the original cluster to the target cluster according to the migration information, wherein the request traffic is served by the target resource, so that the problem that the resources in the cluster cannot be subjected to hot migration in the related technology is solved. And further, the effect of carrying out hot migration on the resources in the cluster is achieved.
