Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, there is shown a flowchart for implementing an application processing method provided in the embodiment of the present application, where the method may include the following steps:
s110: and determining a target application to be subjected to backup processing in the K8S environment.
The target application is a stateful application.
In the K8S environment, a master node and a plurality of working nodes can be deployed, and various applications can be run on the working nodes. Such as stateful applications, stateless applications, etc. Stateful (stateful) refers to the presence of a data storage function. Stateless refers to an operation that cannot save data. For stateless applications, when a problem occurs, an application can be directly restarted without backing up the application, and for stateful applications, when a problem occurs, the restoration needs to be performed depending on previous configuration information, service data and the like, so that the stateful applications need to be backed up.
When there is a backup requirement for the stateful application, a user may send a corresponding backup request, where the backup request may carry application information to be backed up. The backup request can be received through an application program interface service (API Server), and based on the backup request, the target application to be subjected to the backup processing in the K8S environment is determined.
After the target application to be subjected to the backup processing in the K8S environment is determined, the operations of the subsequent steps can be continuously executed.
S120: and backing up the current configuration information of the target application in the service database.
In this embodiment of the application, after determining the target application to be backed up in the K8S environment, the current configuration information of the target application in the service database may be backed up. The service database may be an ETCD, and the configuration information of the target application may be recorded in the service database.
The current configuration information of the target application may include current container image version information, persistent volumes, persistent volume declarations, configuration parameter information, and configuration script information of the target application. The configuration script information is information such as a yaml file for recording specification, execution environment, and the like. Persistent Volume (PV) is an abstraction of the underlying shared storage, and is related to the implementation of the specific underlying shared storage technology, such as Ceph (a distributed File System), GlusterFS (an open source distributed File System), NFS (Network File System), and the like. The Persistent Volume Claim (PVC) is a statement stored by a user, and the PVC consumes PV resources, and the user who really uses the storage does not need to care about the storage implementation details of the bottom layer, but only needs to directly use the PVC.
In a specific embodiment of the present application, the current configuration information of the target application may be obtained by querying the service database, and then the current configuration information of the target application is written into the backup database. The backup database is different from the service database.
After writing the current configuration information of the target application into the backup database, a link and reference relationship of the current configuration information of the target application may be generated. Corresponding configuration information can be searched in the backup database through the link of the current configuration information of the target application, and the incidence relation between the current configuration information and other configuration information of the target application can be determined through the reference relation of the current configuration information of the target application.
S130: and calling a snapshot interface in the container storage interface, and backing up the current service data of the target application by executing snapshot operation on the current service data of the target application in the service storage.
In the embodiment of the application, a snapshot interface can be added to the container storage interface. Container Storage Interface (CSI) is an industry standard Interface specification jointly formulated by members (members) from communities such as kubernets, messes, dockers, etc., aimed at exposing arbitrary Storage systems to containerized applications. The CSI specification defines a minimum set of operations and deployment recommendations for a Storage Provider (SP) to implement a CSI-compliant plug-in. The main focus of the CSI specification is to declare the interface that the plug-in must implement.
And calling a snapshot interface in the container storage interface to execute snapshot operation on the current business data of the target application in the business storage. A snapshot is a fully available copy of a given data set that includes an image of the corresponding data at some point in time (the point in time at which the copy began). The snapshot may be a copy of the data it represents or may be a replica of the data.
By executing snapshot operation on the current service data of the target application in the service storage, the current service data of the target application can be backed up.
Specifically, a snapshot interface in the container storage interface may be called, a snapshot operation is performed on a service disk corresponding to the persistent volume of the target application in the service storage, a storage snapshot of the target application is generated, then a backup disk is created in the backup storage mounted on the working node where the target application is located, and the storage snapshot of the target application is copied to the backup disk.
Before backing up the current service data of the target application, a backup state machine can be started first, and the state of the backup operation executed on the current service data of the target application is recorded in real time, so that the backup operation can be continuously executed at the place where the problem occurs when the problem occurs in the backup process.
By calling a snapshot interface in the container storage interface, a snapshot operation can be executed on a service disk corresponding to a persistent volume of the target application in service storage, so that a storage snapshot of the target application can be generated. Each disk corresponds to a LUN (Logical Unit Number).
The backup storage can be mounted on a working node where the target application is located, a backup disc is created in the backup storage, and a storage snapshot of the target application, which is generated by performing a snapshot operation on a service disc corresponding to a persistent volume of the target application in the service storage, is copied to the backup disc, so that the backup of the current service data of the target application is realized.
In an embodiment of the present application, a plurality of storage snapshots of a target application in a business storage may be merged, so that only one snapshot point of the target application is saved in the business storage. Specifically, the merging processing may be performed on the multiple storage snapshots of the target application in the service storage when a set time interval is reached, or the merging processing may be performed on the multiple storage snapshots of the target application in the service storage after a snapshot operation is performed on a service disk corresponding to a persistent volume of the target application in the service storage to generate a storage snapshot of the target application and the storage snapshot of the target application is copied to a backup disk. This may reduce the footprint of the storage snapshot in the business storage.
S140: and generating a current backup point based on the current configuration information of the backed-up target application and the current service data of the target application, and updating a backup chain of the target application based on the current backup point.
In the embodiment of the application, the current configuration information of the target application in the service database is backed up, a snapshot interface in the container storage interface is called, a snapshot operation is performed on the current service data of the target application in the service storage, and after the current service data of the target application is backed up, a current backup point can be generated based on the backed-up current configuration information of the target application and the current service data of the target application, and the current backup point can record the link, the reference relationship and the like of the current configuration information of the target application and can also record the snapshot information of the current service data of the target application. The backup processing of the target application at different times may generate corresponding backup points, and a plurality of backup points may form a backup chain. After the current backup point is generated, the backup chain of the target application may be updated based on the current backup point.
For ease of understanding, the backup process provided by the embodiment of the present application is described with reference to the system architecture shown in fig. 2.
The K8S environment may include a master node and a plurality of work nodes, such as a work node 1 and a work node 2, where the work node 1 runs a target application, the target application is a stateful application and is composed of a front-end pod (minimum resource organization unit in K8S) and a database pod, and the work node 2 runs a stateless application. The target application and the stateless application can both perform external service access through kubbeproxy (core component of Kubernetes) deployed on respective nodes. The user can manage the K8S environment through the container cloud management platform. A node proxy kubelet is also running in working node 1 and working node 2, maintaining the pots in operation and providing a kubernets runtime environment.
The main node may be deployed with application program interface services, a backup server, and a container storage interface. A backup client may be deployed in the working node 1. The K8S environment may correspond to business storage and backup storage.
The backup server can receive a backup request for the target application sent by a user through the container cloud management platform through the application program interface service, and determine that the target application in the K8S environment is the application to be backed up.
The backup server side can acquire the current configuration information of the target application by inquiring the service database, and write the current configuration information of the target application into the backup database.
The backup server side can also start a backup state machine, call a snapshot interface in the container storage interface, execute snapshot operation on a service disk corresponding to the persistent volume of the target application in service storage, and generate a storage snapshot of the target application;
the backup client may mount the backup storage to the working node 1, then copy the storage snapshot to a backup disk of the backup storage, and update the backup chain in the backup storage.
According to the embodiment of the application, the snapshot interface is added in the container storage interface, and the independent backup server is deployed in the K8S environment, so that the container storage interface can be controlled to snapshot the corresponding disk in the service storage under the condition that the application is unaware, and the snapshot is backed up to other storage, thereby realizing the backup of the service data of the stateful application. Meanwhile, the backup of the complete stateful application is realized by combining the backup of the stateful application configuration information.
By applying the method provided by the embodiment of the application, after the target application to be backed up in the K8S environment is determined, the current configuration information of the target application in the service database is backed up, the snapshot interface in the container storage interface is called, the current service data of the target application in the service storage is backed up by performing the snapshot operation on the current service data of the target application, a current backup point is generated based on the current configuration information of the backed up target application and the current service data of the target application, and the backup chain of the target application is updated based on the current backup point. When the backup of the target application in the K8S environment is required, the current configuration information and the current service data of the target application can be backed up independently, and the backup of the configuration information of all applications in the whole K8S environment is not required, so that the backup efficiency can be improved, the consumption of excessive resources can be avoided, and the effective recovery of the target application can be realized based on the current configuration information and the current service data of the target application.
In one embodiment of the present application, the method may further comprise the steps of:
the method comprises the following steps: receiving a recovery request for a target application in a K8S environment;
step two: determining a target backup point in a backup chain of the target application according to the recovery request;
step three: exporting the target backup point and the service data corresponding to all backup points before the target backup point to a new disc stored by the service;
step four: creating a new persistent volume and a new persistent volume declaration for the new disk;
step five: and recovering the target application based on the configuration information corresponding to the target backup point, and associating a new persistent volume statement.
For convenience of description, the above steps are combined for illustration.
The target application may not operate normally due to errors, exceptions, etc., and in this case, the target application needs to be recovered. A corresponding recovery request may be issued by the user. After receiving a restore request for a target application in the K8S environment, a target backup point in a backup chain of the target application may be determined based on the restore request. The recovery request can carry the information of the target backup point, and the target backup point can be determined by analyzing the recovery request.
After the target backup point is determined, the service data corresponding to the target backup point and all backup points before the target backup point in the backup chain can be exported to a new disk of the service storage, and the service data exported to the new disk of the service storage can be merged.
For a new disk, a new persistent volume and a new persistent volume declaration may be created.
Then, the configuration information corresponding to the target backup point is obtained, the configuration information corresponding to the target backup point can be obtained by reading the backup database, the target application can be recovered based on the configuration information corresponding to the target backup point, and then a new persistent volume statement can be associated, so that the target application can normally run.
According to the embodiment of the application, the target application can be quickly restored based on the backup chain of the target application, and the influence on the normal operation of the target application is avoided.
