Description

Technical Field

[0001] The present application relates to a field, and in particular, to a resource migration method, device, processor and electronic device. Background Art

[0002] K8s cluster migration is a common demand scenario in PaaS cloud operation and maintenance. In scenarios such as infrastructure changes, K8s upgrades, and technical architecture transformation, there will be a need for K8s cluster migration. Generally, K8s cluster migration mainly refers to recreating K8s resources in the source cluster in the target cluster. In addition to the migration of K8s resources, the migration of cluster traffic is equally important. In actual migration scenarios, applications hope that the service interruption time caused by migration to the business will be as short as possible.

[0003] Most of the existing k8s cluster migration technical solutions are based on the redeployment of cluster resources, that is, redeploying cluster resources in the target cluster according to the original deployment mode of the source cluster k8s resources. This technical solution generally requires sorting out the source cluster k8s resource list and ownership, sorting out the k8s resource creation logic, formulating and integrating the migration plan of each k8s resource, and formulating and integrating the emergency fallback plan of each k8s resource migration.

[0004] The k8s cluster migration technology solution based on cluster resource redeployment has the disadvantages of low automation, long closed loop, and poor versatility. Since the core idea of ​​this solution is to execute the original cluster resource deployment steps in the target cluster as is to achieve the effect of cluster migration, but since the k8s cluster is an infrastructure shared by multiple users, this will result in each user providing their own migration and fallback solutions, and the cloud platform operation and maintenance personnel will integrate them, which increases the uncertainty of migration. In addition, since each cluster deploys different resources and involves different applications, the migration solution varies from cluster to cluster and has poor versatility. Finally, the migration of cluster traffic is not considered, which will lead to the interruption of external service of applications during cluster migration.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] It should be noted that the relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties. For example, an interface is set between this system and the relevant user or organization. Before obtaining relevant information, it is necessary to send an acquisition request to the aforementioned user or organization through the interface, and obtain relevant information after receiving the consent information fed back by the aforementioned user or organization.

[0029] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a resource migration method provided according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0030] Step S102, obtaining a migration request for migrating a plurality of resources to be migrated in the original cluster;

[0031] Step S104, responding to the migration request, performing an operation of migrating multiple resources to be migrated in the original cluster to the target cluster;

[0032] Step S106, in the process of migrating the multiple resources to be migrated in the original cluster to the target cluster, if it is detected that there is a target resource that can provide external services in the target cluster, then determine the migration information of the target resource, wherein the multiple resources to be migrated include the target resource, and the migration information is used to indicate the migration progress of the target resource relative to the multiple resources to be migrated;

[0033] Step S108: Migrate 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 resources.

[0034] Through this application, the following steps are adopted: obtaining a migration request for migrating multiple resources to be migrated in the original cluster; responding to the migration request, executing the operation of migrating multiple resources to be migrated in the original cluster to the target cluster; in the process of migrating multiple resources to be migrated in the original cluster to the target cluster, if it is detected that there is a target resource that can provide external services in the target cluster, then determining the migration information of the target resource, wherein the migration information is used to indicate the migration progress of the target resource relative to the multiple resources to be migrated; migrating the request traffic of the original cluster to the target cluster according to the migration information, wherein the request traffic is provided by the target resource, solving the problem that the resources in the cluster cannot be hot migrated in the related technology. Thus, the effect of hot migration of resources in the cluster is achieved.

[0035] The cluster in the above steps S102 to S108 can be a k8s cluster, that is, the original cluster and the target cluster are both k8s clusters; the above steps are used to migrate resources in the original k8s cluster to the target k8s cluster.

[0036] In the above step S106, the process of migrating multiple resources to be migrated in the original cluster to the target cluster can adopt a grayscale migration strategy, wherein the grayscale migration strategy refers to splitting the multiple services supported by the multiple resources to be migrated and then migrating them one by one. Therefore, during the migration process, as long as the resources to be migrated that support a certain service are migrated, the services supported by the migrated resources can be used, without having to wait for the multiple resources to be migrated to be completely migrated before starting to use the migrated resources.

[0037] For example, when multiple resources to be migrated in the original cluster support service A, service B, and service C, grayscale migration means: first transmit the resources to be migrated corresponding to service A, then transmit the resources to be migrated corresponding to service B, and finally transmit the resources to be migrated corresponding to service C; during the transmission period, if the resources to be migrated of service A complete the migration, the target cluster can immediately use the migrated resources to execute service A; while the traditional migration solution requires that all the resources to be migrated in the original cluster complete the migration before the services in it can be used.

[0038] In the above step S104, in the process of migrating multiple resources to be migrated in the original cluster to the target cluster, a cloud storage device can be used as an intermediate device between the original cluster and the target cluster. The cloud storage device copies the files to be migrated from the original cluster and then restores the files to be migrated in the cloud storage device to the target cluster.

[0039] Optionally, in the resource migration method provided in an embodiment of the present application, in response to a migration request, the operation of migrating multiple resources to be migrated in the original cluster to the target cluster includes: copying the multiple resources to be migrated in the original cluster to a cloud storage device; and restoring the multiple resources to be migrated received by the cloud storage device to the target cluster.

[0040] It should be noted that cloud storage devices are used to store the original files of the resources to be transferred in the original cluster. The migration tool currently supports object storage cloud storage services, including object storage services of mainstream public cloud vendors such as AWS, GCP, and Azure. In addition, it also supports any object storage compatible with the Amazon S3 interface.

[0041] Figure 2 is a schematic diagram of a resource migration solution provided according to an embodiment of the present application, such as Figure 2 As shown, a migration tool is provided in the cluster, and the migration tool executes the copying and recovery functions of resources. In the case where the cluster is a k8s cluster, the original cluster is the original k8s cluster 2022, and the target cluster is the target k8s cluster 2042. The migration tool in the original cluster is the first migration tool 2024 for executing the copy function, and the migration tool in the target cluster is the second migration tool 2044 for executing the recovery function.

[0042] Alternatively, if Figure 2 As shown, the original cluster is connected to the cloud storage device 206 via the first migration tool 2024, which is used to copy multiple resources to be migrated in the original cluster to the cloud storage device, and the target cluster is connected to the cloud storage device 206 via the second migration tool 2044, which is used to copy multiple resources to be migrated in the cloud storage device to the target cluster.

[0043] Alternatively, if Figure 2 As shown, the resource migration solution also includes a migration management module 208 connected to the original cluster and the target cluster, wherein the migration management module is a control module for cluster migration, and mainly provides capabilities such as cluster resource migration 2082, cluster traffic migration 2084, and cluster migration monitoring 2086.

[0044] Optionally, the migration tool mainly provides the copying and recovery functions of k8s resources, that is, during the migration process, the migration tool is first used to complete the copying of k8s resources in the source cluster, and then the k8s resources are restored in the target cluster, thereby completing the migration of k8s resources.

[0045] Optionally, the migration tool needs to be deployed in both the source k8s cluster and the target k8s cluster, and is called by the migration management module to perform operations such as resource copying and resource recovery according to the calling parameters.

[0046] Optionally, in the resource migration method provided in the embodiment of the present application, in response to the migration request, executing the operation of migrating multiple resources to be migrated in the original cluster to the target cluster includes: checking whether the calling interfaces of the original cluster and the target cluster are successfully connected to the cloud storage device; in the case that the calling interfaces of the original cluster and the target cluster are successfully connected to the cloud storage device, identifying the task type indicated by the migration request, wherein the task types include: resource copy task and resource recovery task; in the case that the task type is a resource copy task, copying the multiple resources to be migrated in the original cluster to the cloud storage device; in the case that the task type is a resource recovery task, restoring the multiple resources to be migrated received by the cloud storage device to the target cluster.

[0047] Optionally, the calling interface can be the kube-apiserver interface in the k8s cluster.

[0048] In the above-mentioned embodiment of the present invention, the migration request is used to indicate the task type of the migration task, wherein the task type of the migration request can be divided into a resource copy task and a resource recovery task. The resource copy task is executed by the original cluster, and multiple resources to be migrated in the original cluster are copied to the cloud storage device; the resource recovery task is executed by the target cluster, and multiple resources to be migrated received by the cloud storage device are restored to the target cluster, so that the resource copy task and the resource recovery task can be executed by the original cluster and the target cluster respectively, thereby realizing reasonable allocation of resource migration tasks.

[0049] Figure 3 is a schematic diagram of executing resource copy and resource recovery according to an embodiment of the present application, such as Figure 3 As shown, the following steps are included:

[0050] S301: Receive a migration request sent by a migration management module.

[0051] S302, execute the health check logic of the migration tool, mainly to check whether the cloud storage device is successfully connected and whether the kube-apiserver of the k8s cluster is successfully connected. If any of the cloud storage and kube-apiserver fails to connect, an error is returned and the request processing ends.

[0052] S303, judging whether a resource copy or resource recovery task needs to be executed according to the migration parameters of the migration request, if it is a resource copy task, executing step S304, if it is a resource import task, executing step S314.

[0053] S304: If it is a resource copy task, query the kube-apiserver for all resources in the cluster (ie, resources to be migrated), and upload the original files of all resources (ie, resources to be migrated) to the cloud storage device.

[0054] S305, determining whether the resource copy task is completed, or determining whether the resource copy task has timed out, if so, then the process ends, otherwise, returning to step S304 based on executing the resource copy task.

[0055] S314, if it is a resource recovery task, the original file of the k8s resource is obtained from the cloud storage device, and the kube-apiserver of the target cluster is called to restore all k8s resources (ie, resources to be migrated).

[0056] S315, determine whether the resource recovery task is completed, or determine whether the resource recovery task has timed out. If so, end it; otherwise, return to step S314 based on executing the resource recovery task.

[0057] It should be noted that kube-apiserver is one of the most important cores of k8s. Its main functions include: - providing a rest api interface for cluster management, including authentication and authorization, data verification, and primary cluster status changes; providing data interaction and communication with other modules. Among them, only the api server can directly operate the etcd database.

[0058] Alternatively, if Figure 2 As shown, the migration management module includes: a cluster resource migration module, a cluster traffic migration module, and a cluster migration monitoring module.

[0059] Alternatively, if Figure 2 As shown, the cluster resource migration module provides the management capability of resource migration tasks, mainly including: configuration of resource migration parameters and scheduling of resource migration tasks.

[0060] Optionally, in the resource migration method provided in an embodiment of the present application, responding to a migration request and migrating resources in an original cluster to a target cluster includes: identifying migration parameters in the migration request, wherein the migration parameters include at least: a migration address, a migration resource namespace, and a migration resource type; configuring the original cluster and the target cluster to be connected according to the migration address; determining, from the original cluster according to the migration resource namespace or the migration resource type, a plurality of resources to be migrated that require resource migration; and migrating the resources to be migrated to the target cluster.

[0061] Optionally, the migration parameters also include: a cloud storage address of the cloud storage device.

[0062] In the above-mentioned embodiments of the present invention, the addresses of the original cluster and the target cluster are indicated by migration parameters in the migration request to determine the device cluster that needs to perform resource migration; the resources to be migrated that need to be migrated are indicated by the migration resource namespace or the migration resource type to realize the selection of the resources to be migrated; thus, the resources to be migrated can be specified according to the migration resource namespace or the migration resource type according to the actual scenario requirements, thereby improving the flexibility of cluster migration.

[0063] Optionally, the configuration of resource migration parameters is used to configure migration parameters, where the migration parameters are shown in Table 1. By migrating the resource namespace and migrating the resource type parameters, specific k8s resources can be specified for migration according to actual scenario requirements, thereby improving the flexibility of cluster migration.

[0064] Parameter name Parameter Value illustrate Task Type Copy / Restore / Cloud storage address xx.xx.xx.xx Cloud storage service address kube-apiserver address xx.xx.xx.xx kube-apiserver service address Migrating resource namespaces demo-namespaces Specify the migration of a namespace resource Migrate resource types configmap Specify the migration of a certain type of resources

[0065] Table 1

[0066] Optionally, in the resource migration method provided in an embodiment of the present application, responding to a migration request and migrating resources in an original cluster to a target cluster includes: responding to the migration request and identifying dependencies between multiple resources to be migrated in the original cluster; determining a migration order of multiple resources to be migrated based on the dependencies; and migrating multiple resources to be migrated in the original cluster to the target cluster according to the migration order.

[0067] Optionally, the orchestration of resource migration tasks enables the control of the migration order of resources to be migrated. In a multi-cloud scenario, a service is sometimes provided by applications deployed in multiple different k8s clusters, which are mutually dependent. The orchestration of resource migration tasks can be used to migrate multiple clusters in the required order.

[0068] Optionally, in the resource migration method provided in an embodiment of the present application, migrating the request traffic of the original cluster to the target cluster according to the migration information includes: determining a grayscale ratio according to the migration information, wherein the grayscale ratio is used to represent the ratio of the target resource amount of the target resource to the total migration resource amount, and the total migration resource amount is the resource amount of multiple resources to be migrated in the original cluster before the migration starts; determining the migration ratio of the request traffic according to the grayscale ratio; and migrating the request traffic of the original cluster to the target cluster based on the migration ratio.

[0069] In the above-mentioned embodiments of the present invention, the grayscale ratio refers to the ratio of the target resource amount of the target resource to the total migration resource amount of all resources to be migrated in the original cluster. According to the grayscale ratio, the request traffic can be determined, and part of the request traffic executed in the original cluster can be migrated to the target cluster for execution, thereby achieving the technical effect of hot migration of resources in the cluster.

[0070] Optionally, in the resource migration method provided in an embodiment of the present application, migrating the request traffic of the original cluster to the target cluster according to the migration information includes: determining the grayscale time according to the migration information, wherein the grayscale time is used to represent the migration time of migrating multiple resources to be migrated from the original cluster to the target cluster; when the grayscale time exceeds a predetermined time threshold, all request traffic of the original cluster is migrated to the target cluster.

[0071] In the above-mentioned embodiment of the present invention, the predetermined time threshold is a pre-set total migration time required to migrate all resources to be migrated in the original cluster to the target cluster. Furthermore, when the grayscale time exceeds the predetermined time threshold, it indicates that all resources in the original cluster have been migrated to the target cluster, and all request traffic executed by the original cluster is migrated to the target cluster.

[0072] Alternatively, if Figure 2 As shown, the cluster traffic migration module mainly provides the ability to migrate application traffic (ie, request traffic) during the cluster migration process, and realizes hot migration of the cluster in combination with cluster resource migration.

[0073] Optionally, the parameters involved in the cluster traffic migration task are shown in Table 2. The traffic migration instance can be specified by configuring the service name, and the grayscale strategy of traffic switching can be specified by the grayscale ratio and grayscale time.

[0074] Parameter name Parameter Value illustrate Service Name Mysql-0010 Name of the traffic service instance to be migrated Service domain name http: / / mysql:8080 Domain name for external service access Health Check Probes http: / / healthy:2020 Used to check whether the service is healthy Grayscale ratio 20％ Traffic migration grayscale ratio Gray Time 30min Traffic migration grayscale time

[0075] Table 2

[0076] Figure 4 is a schematic diagram of a traffic migration provided according to an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0077] S401, receiving a migration management module request.

[0078] S402, query whether the specified service instance (ie, target resource) in the target k8s cluster is ready, that is, whether the recovery is successful. If not, retry; if ready, execute step S403.

[0079] S403, calling the service health check probe to check whether the application of the target resource can provide external services. If the health check fails, retry; if the check succeeds, execute step S404.

[0080] S404, calling DNS to modify the domain name resolution configuration, and migrating a portion of the request traffic to the target cluster application according to the grayscale ratio.

[0081] S405, checking whether the grayscale time has timed out (ie, checking whether the grayscale time has exceeded a predetermined time threshold), if so, executing step S406, if not, returning to step S404.

[0082] S406, calling DNS to modify the domain name resolution configuration, and migrating all request traffic to the target cluster application.

[0083] Alternatively, if Figure 2 As shown in the figure, the cluster migration monitoring module mainly displays the monitoring indicators during the cluster migration process. Among them, the monitoring indicators are divided into two categories. One is the monitoring indicators of cluster resource migration, which mainly include: the total amount of cluster resource migration, the total amount of migrated resources, the migration time, etc.; the other is the monitoring indicators of cluster traffic migration, which mainly include: traffic migration progress, the success rate of requests during traffic migration grayscale, request time, etc.

[0084] Compared with the existing k8s cluster migration technology, the present invention has the advantages of high automation and strong versatility. By connecting to kube-apiserver and cloud storage, highly automated cluster resource copying and recovery capabilities are achieved, the migration logic is coded, and the migration efficiency is improved. And compared with the existing k8s cluster migration technology, the present invention has the advantages of little impact on the business and uninterrupted external services. By adding a cluster traffic migration mechanism, application traffic is migrated while cluster resources are migrated, and the stability of traffic migration is ensured through a grayscale strategy, the ability of cluster hot migration is realized; thereby overcoming the shortcomings of the existing k8s cluster migration technology, such as low automation, poor versatility, and inability to guarantee application business continuity.

[0085] The resource migration method provided in the embodiment of the present application obtains a migration request for migrating multiple resources to be migrated in the original cluster; responds to the migration request, and performs an operation of migrating multiple resources to be migrated in the original cluster to the target cluster; in the process of migrating multiple resources to be migrated in the original cluster to the target cluster, if it is detected that there is a target resource that can provide external services in the target cluster, the migration information of the target resource is determined, wherein the migration information is used to indicate the migration progress of the target resource relative to the multiple resources to be migrated; according to the migration information, the request traffic of the original cluster is migrated to the target cluster, wherein the request traffic is provided by the target resource, thereby solving the problem that the resources in the cluster cannot be hot migrated in the related technology. Thus, the effect of hot migration of resources in the cluster is achieved.

[0086] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
