[0072] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0073] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0074] Kubernetes (k8s for short) is a container orchestration engine that supports automated deployment, large-scale scalability, and application container management. It has become a standard in the field of container orchestration. It has the advantages of managing large container clusters and providing high reliability services.

[0075] For distributed applications in a large k8s container cluster, there are two situations where application migration is required:

[0076] Case 1: Cluster version upgrade: Cluster version upgrade (for example, the operating system or interface service version upgrade that the applications in the cluster rely on) cannot guarantee the compatibility between multiple versions. If the application configuration of the old cluster is used with the new cluster, the service may not be created. For example, some parameters of the new version of the cluster have been abandoned.

[0077] Case 2: Deploy the application in multiple clusters. When a cluster has a problem, you can migrate the application from that cluster to another cluster.

[0078] Currently, there is no solution that can smoothly migrate applications between multiple clusters. Most of the time, operations and maintenance personnel manually upgrade the applications in the cluster, such as manually creating the configuration corresponding to the migrated application in the new cluster, which makes it difficult to ensure stable service startup and traffic switching during the entire application migration process, resulting in low efficiency of application migration. Currently.

[0079] Therefore, the present application provides an application migration method. In order to maintain the consistency between the old and new clusters, the configuration information of the target application is created in the new cluster (i.e., the second cluster) according to the configuration information of the target application in the old cluster (i.e., the first cluster). Then, in order to ensure the stability of the service, a part of the traffic can be migrated to the new cluster, and the traffic of the new cluster and the old cluster can be mixed. After the new cluster is normal, the remaining traffic can be migrated from the old cluster to the new cluster, thereby achieving lossless traffic during the migration process and improving the efficiency of application migration.

[0080] For ease of understanding, the following Figure 1 The examples are used to illustrate the application scenarios to which the embodiments of the present application are applicable.

[0081] Figure 1 For a schematic diagram of an application scenario applicable to this application, please see Figure 1 , including: a first cluster 101, a second cluster 102, and a migration server 103. The first cluster 101 includes multiple servers, each server serves as a node in the first cluster 101. The second cluster 102 includes multiple servers, each server serves as a node in the second cluster 102.

[0082] The nodes of the first cluster 101, the nodes of the second cluster 102, and the migration server 103 can communicate and collaborate with each other through the network. It can be understood that the client of the application also accesses the nodes in the cluster through the network.

[0083] When there is a need for application migration, the target application in the first cluster 101 needs to be migrated to the second cluster. The migration server 103 can create the configuration information of the target application in the second cluster 102 according to the configuration information of the target application in the first cluster 102, so that the target application remains consistent between the two clusters to determine the stability of the services provided by the target application.

[0084] Then, the migration server 103 can migrate part of the traffic of the client accessing the target application in the first cluster 101 to the target application in the second cluster 102 by load balancing, so that the traffic is intact during the migration process. After the target application in the second cluster 102 is normal, the remaining traffic is migrated to the second cluster, so as to realize the migration of the target application between the first cluster 101 and the second cluster 102.

[0085] Exemplarily, the target application may include multiple microservices, each of which is responsible for one function. Taking the first cluster 101 as an example, the target application is deployed in the first cluster 101, and the multiple microservices may be deployed on multiple nodes in the first cluster 101 for separate deployment and operation. During application migration, the multiple microservices of the target application may also be deployed on multiple nodes in the second cluster 102.

[0086] It can be understood that the number of nodes in the first cluster 101 and the second cluster 102 can be multiple, which is not shown in the figure.

[0087] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments may exist independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0088] Figure 2 A flow chart of an application migration method provided in an embodiment of the present application, the method can be executed by a migration server, or by an application migration device set in the migration server, the device can be a chip, a chip module, or an integrated development environment (IDE), etc., refer to Figure 2 , the method comprises the following steps:

[0089] S201. Obtain first configuration information of a target application in a first cluster.

[0090] When application migration is triggered, the migration server may obtain first configuration information of the target application in the first cluster, that is, the migration server may detect service dependencies of the target application in the first cluster.

[0091] Exemplarily, the first configuration information may include, for example, port information, storage space information, and configuration files of the target application.

[0092] The storage space information may be, for example, storage information of storage mounted via a persistent volume (PV) / persistent volume claim (PVC).

[0093] The port information may be, for example, port information of a port for external cluster traffic exposed by the target application to access an application within the cluster, such as a node port (Nodeport).

[0094] The configuration file may be, for example, a configuration file mounted by the target application through a Configmap component.

[0095] In one possible implementation, application migration can be triggered in the following ways:

[0096] The migration server may obtain an application migration request, where the application migration request includes an identifier of a target application, an identifier of a first cluster, and an identifier of a second cluster to which the target application is to be migrated.

[0097] Then, the migration server may obtain the first configuration information from the first cluster according to the application migration request. Specifically, the migration server may detect the first configuration information of the target application from the first cluster according to the identifier of the first cluster and the identifier of the target application.

[0098] Among them, the application migration request can be manually triggered by the operation and maintenance personnel when determining that the application needs to be migrated, or the migration server can send application migration information to the terminal device of the operation and maintenance personnel when detecting the need for application migration (for example, there is a version upgrade in the first cluster) to obtain the application migration request sent by the operation and maintenance personnel through their terminal device to confirm the application migration.

[0099] S202: Create second configuration information of the target application in the second cluster according to the first configuration information.

[0100] After acquiring the first configuration information, the migration server may create second configuration information of the target application in the second cluster according to the first configuration information.

[0101] Specifically, the migration server may create second configuration information of the target application in the second cluster.

[0102] S203: Start the second cluster based on the second configuration information.

[0103] After creating the second configuration information, the migration server may start the second cluster based on the second configuration information. After the second cluster is successfully started, the target application in the second cluster is started.

[0104] S204: Migrate a preset proportion of traffic of the target application from the first cluster to the second cluster.

[0105] After the second cluster is successfully started, the migration service can migrate a preset proportion of traffic of the target application from the first cluster to the second cluster.

[0106] Exemplarily, the preset ratio may be 10% or 30%, ie, a small portion of the traffic of the target application of the first cluster.

[0107] It can be understood that at this time, a preset proportion of traffic accesses the target application of the second cluster, and the remaining traffic accesses the target application of the first cluster, thereby achieving mixed traffic operation.

[0108] S205: Determine a first state of the target application in the second cluster, where the first state is a normal state or an abnormal state.

[0109] After migrating part of the traffic to the first cluster, a first state of the target application in the second cluster may be determined, where the first state is a normal state or an abnormal state.

[0110] Exemplarily, the first state may be determined by determining whether the target application in the second cluster can provide services normally.

[0111] S206: If the first state is a normal state, migrate the remaining traffic of the target application except for a preset proportion of traffic from the first cluster to the second cluster.

[0112] If the first state is a normal state, the migration server may migrate the remaining traffic of the target application except for a preset proportion of traffic from the first cluster to the second cluster.

[0113] If the first state is an abnormal state, the migration server may perform a rollback operation to migrate a preset proportion of traffic of the target application to the first cluster to ensure normal provision of services.

[0114] In this embodiment, the first configuration information of the target application in the first cluster is obtained, and the second configuration information of the target application in the second cluster is created according to the first configuration information, and then the second cluster is started based on the second configuration information. After startup, a preset proportion of the traffic of the target application is migrated from the first cluster to the second cluster, and the first state of the target application in the second cluster is determined. If the first state is a normal state, the remaining traffic of the target application is migrated from the first cluster to the second cluster, and traffic mixing is achieved during the migration process, so that the traffic is lossless during the application migration process, and the stability of the service is ensured, thereby improving the migration efficiency.

[0115] Next, another application migration method provided by the present application is described through another embodiment.

[0116] Figure 3 A flow chart of another application migration method provided in an embodiment of the present application, the method can be executed by a migration server, or by an application migration device set in the migration server, the device can be a chip, a chip module, or an IDE, etc., refer to Figure 3 , the method comprises the following steps:

[0117] S301: Obtain first configuration information of a target application in a first cluster.

[0118] For the description of the first configuration information, reference may be made to the above embodiment and will not be repeated here.

[0119] S302: Determine an information configuration specification for the second cluster.

[0120] When creating the second configuration information in the second cluster, an information configuration specification of the second cluster may be determined. The information configuration specification may be understood as the format of the second cluster configuration information, which may include template parameters for configuring relevant configuration information of the target application in the second cluster.

[0121] S303: Create second configuration information in the second cluster according to the port information, the storage space information, and the configuration file and the information configuration specification.

[0122] The migration server may create the second configuration information in the second cluster according to the port information, storage space information, and configuration file in the first configuration information and the information configuration specification of the second cluster.

[0123] S304: Start the second cluster based on the second configuration information.

[0124] S305: Migrate a preset proportion of traffic of the target application from the first cluster to the second cluster.

[0125] After starting the second cluster, the migration server may migrate a preset proportion of traffic of the target application from the first cluster to the second cluster.

[0126] In a possible implementation, in order to further improve the stability of services provided by the target application, the migration server may perform health monitoring on the second cluster after starting the second cluster to obtain a second state of the second cluster, where the second state is a healthy state or an unhealthy state.

[0127] If the second state is a healthy state, it means that the target application in the second cluster is available, and a preset proportion of traffic of the target application can be migrated from the first cluster to the second cluster.

[0128] If the second state is an unhealthy state, it means that the target application in the second cluster is unavailable. It can also be understood that the unhealthy state of the second cluster will affect the stability of services provided by the target application. The health of the second cluster can be continuously monitored without traffic migration until the second state of the second cluster is a healthy state, and then the traffic migration operation can be performed.

[0129] Exemplarily, the migration server may migrate a preset proportion of traffic of the target application from the first cluster to the second cluster through a load balancing system (Nginx, etc.).

[0130] S306: Within a preset time period after the second cluster is successfully started, determine whether the first state of the target application in the second cluster is a normal state.

[0131] If the first state of the target application in the second cluster is a normal state, S307 is executed; if the first state of the target application in the second cluster is not a normal state, that is, the first state is an abnormal state, S308 is executed.

[0132] Exemplarily, the migration server may make a judgment once or multiple times within a preset time period, and the multiple judgments may be made at preset time intervals.

[0133] In a possible implementation, the migration server can track multiple service requests corresponding to the target application in the second cluster through link tracking within a preset time after the second cluster is successfully started, and determine whether the service requests are executed. If it is determined that the multiple service requests are executed, the first state is determined to be a normal state. If it is determined that at least one service request among the multiple service requests is not executed, the first state is determined to be an abnormal state.

[0134] In another possible implementation, the migration server can detect the log of the target application in the second cluster within a preset time after the second cluster is successfully started, and if no log alarm is detected, the first state is determined to be a normal state, and if a log alarm is detected, the first state is determined to be an abnormal state. The log alarm is determined based on the log of the target application, and if the target application is abnormal, a log alarm will be generated.

[0135] Through the above two methods, the migration server can determine the first state of the target application to ensure whether the target application of the second cluster is available, thereby ensuring the stability of the service.

[0136] S307: Migrate the remaining traffic of the target application except for a preset proportion of traffic from the first cluster to the second cluster.

[0137] If the first state of the target application in the second cluster is a normal state, the migration server may migrate the remaining traffic of the target application except for a preset proportion of traffic from the first cluster to the second cluster to provide corresponding services through the target application of the second cluster.

[0138] In a possible implementation, after migrating the remaining traffic of the target application except for a preset proportion of traffic from the first cluster to the second cluster, the migration server may perform a recycling operation of the target application of the first cluster, thereby releasing resources of the first cluster.

[0139] S308: Perform a rollback operation on the target application, and migrate a preset proportion of traffic of the target application to the first cluster.

[0140] If the first state of the target application in the second cluster is an abnormal state, the migration server may perform a rollback operation on the target application and migrate a preset proportion of traffic of the target application to the first cluster to ensure that the service request of the client is normally served.

[0141] In this embodiment, by obtaining the first configuration information of the target application in the first cluster and determining the information configuration specification of the second cluster, the second configuration information is then created in the second cluster according to the port information, storage space information, and configuration files in accordance with the information configuration specification. The second cluster is then started based on the second configuration information, and after startup, a preset proportion of the traffic of the target application is migrated from the first cluster to the second cluster, and within a preset time after the second cluster is successfully started, it is determined whether the first state of the target application in the second cluster is a normal state. If so, the remaining traffic of the target application is migrated from the first cluster to the second cluster. If not, a rollback operation is performed on the target application, and a preset proportion of the traffic of the target application is migrated to the first cluster, so that the client's service request can obtain normal service. The embodiment of the present application realizes mixed traffic during the migration process, so that the traffic is lossless during the application migration process, and the stability of the service is ensured, thereby improving the migration efficiency.
