[0035] Embodiment one

[0036] Figure 1 A flowchart of a configuration updating method is provided for the first embodiment of the present application. The present embodiment can be applied to the case of combining the configuration management resource object of the container management cluster with the external shared storage to realize efficient synchronization and consistency guarantee of configuration information. The method can be executed by a configuration updating device, which can be realized in the form of hardware and / or software, and can be configured in various general-purpose computing devices. As shown in the figure, the method comprises: Figure 1

[0037] S110, creating a mounting configuration of the shared storage; the shared storage stores a configuration file containing configuration information in the configuration management resource object.

[0038] The shared storage is an architecture for realizing data sharing of multiple devices or processes through shared storage resources, which can improve the data consistency and reliability of shared objects. For example, the shared storage is a network file system, a reliable autonomous distributed object storage system, or a distributed file system. The shared storage stores a configuration file containing configuration information in the configuration management resource object. Specifically, the content of the configuration management resource object can be written into the shared storage by an external script to form a configuration file.

[0039] In the embodiment of the present application, in order to enable the container group to read the configuration information in the shared storage, the mounting configuration of the shared storage is first created in the container group. Specifically, the content of the initial configuration management resource object is written into the shared storage by initializing the container or an external script, so that the shared storage obtains the initial configuration information. Then, the directory of the shared storage is mounted to the local working path pre-set in the container group, so that the processes in the container group can access the shared storage in the form of directly accessing local files.

[0040] ​In one specific example, the shared storage is a network file system, and a persistent volume can be created first, then a persistent volume claim is created, and finally the shared storage is mounted to a local working path. Subsequent container groups can access the shared storage by directly accessing the local working path.

[0041] S120, in response to the configuration file change message initiated by the file change monitoring system, obtaining the updated configuration file from the shared storage based on the mounting configuration.

[0042] The file change monitoring system runs in the node where the current container group is located, and is used for change monitoring of the configuration file in the shared storage.

[0043] In the embodiment of the application, the shared storage updates the current configuration file stored in response to listening to the configuration management resource object update event of the container management cluster, and updates the configuration management resource object based on the updated configuration management resource object. In order to realize efficient updating of configuration information in the container group, the file change monitoring system is used for change monitoring of the configuration file in the shared storage. When it is detected that the configuration file in the shared storage is changed, the file change monitoring system sends a configuration file change message to the container group to ensure that the container group can obtain the updated configuration information in time. The container group obtains the updated configuration file from the shared storage based on the mounting configuration in response to the configuration file change message initiated by the file change monitoring system.

[0044] By monitoring the configuration file in the shared storage through the file change monitoring system, it can be ensured that the container group can obtain the latest configuration information in time, and the synchronization delay of the traditional updating method is solved, and the configuration synchronization efficiency is improved. By creating the shared storage mounting configuration, the processes in the container group access the shared storage in the form of directly accessing local files, and based on the efficient access performance of the shared storage, in the scene of frequent configuration updating, the configuration updating performance can be greatly improved.

[0045] By using the strong consistency feature of the shared storage, it is ensured that the container groups in all nodes of the cluster obtain the same configuration information, and the inconsistency problem caused by concurrent access is avoided. Moreover, by using the high-availability design of the shared storage, even if some nodes fail, other nodes can still access the latest configuration information, and the high availability of the system is ensured.

[0046] In one specific example, when the file change monitoring system detects that at least one configuration file in the shared storage is changed, the target container group associated with the changed configuration file is determined according to the mapping relationship table of the configuration file and the container group, and a configuration file change message is sent to the target container group. The target container group obtains the updated configuration file from the shared storage based on the mounting configuration.

[0047] In another specific example, when the file change monitoring system detects a change in at least one configuration file in shared storage, it sends a configuration file change message to the container group on the corresponding node to ensure that the container group can obtain the updated configuration information in a timely manner. In response to the configuration file change message initiated by the file change monitoring system, the container group retrieves the updated configuration file from the shared storage based on the mounted configuration. It can then determine the target updated configuration information associated with the current container group from the retrieved updated configuration information.

[0048] Optionally, before retrieving the updated configuration file from shared storage based on the mount configuration in response to a configuration file change message initiated by the file change monitoring system, the following steps are also included:

[0049] Mount the initial configuration management resource object in the container management cluster to the designated directory; the initial configuration management resource object includes the current configuration information.

[0050] In this optional embodiment, in response to a configuration file change message initiated by the file change monitoring system, before retrieving the updated configuration file from shared storage based on the mounted configuration, the initial configuration management resource object in the container management cluster is mounted to a designated directory to obtain the initial configuration information as the current configuration information in the container group. The initial configuration management resource object includes the current configuration information. Specifically, the initial configuration management resource object is mounted to the designated directory via a volume to obtain the current configuration information, enabling containers to directly access the configuration information within the initial configuration management resource object.

[0051] S130. Update the current configuration information based on the updated configuration file.

[0052] In this embodiment of the invention, containers in a container group can read the updated configuration information in the update configuration file, and then update the current configuration information based on the updated configuration information. Specifically, in the update configuration file, a target update configuration file associated with the current container group is determined, and the current configuration information is updated based on the target update configuration file.

[0053] The technical solution of this invention creates a shared storage mount configuration, responds to a configuration file change message initiated by the file change monitoring system, obtains an updated configuration file from the shared storage based on the mount configuration, and updates the current configuration information based on the updated configuration file. By monitoring changes to the configuration file in the shared storage and promptly initiating a configuration file change message to the container group when changes occur, efficient synchronization and consistency assurance of configuration information updates can be achieved.

[0054] Example 2

[0055] Figure 2A flowchart of a configuration updating method provided for the second embodiment of the present application is further refined on the basis of the above-mentioned embodiments, and provides specific steps of creating a mounting configuration of shared storage, specific steps of obtaining an updated configuration file from the shared storage based on the mounting configuration in response to a configuration file change message initiated by a file change monitoring system, and specific steps of updating current configuration information based on the updated configuration file. As shown in FIG. 10, the method comprises the following steps. Figure 2

[0056] S210, creating a persistent volume and a persistent volume claim pointing to the shared storage.

[0057] In the embodiment of the present application, in order to mount the shared storage to the local working path, a persistent volume and a persistent volume claim pointing to the shared storage are first created.

[0058] S220, mounting the shared storage to the local working path; the shared storage stores a configuration file containing configuration information in the configuration management resource object.

[0059] In the embodiment of the present application, on the basis of creating the persistent volume and the persistent volume claim, the content of the initial configuration management resource object is written into the shared storage through an initialization container or an external script, so that the shared storage obtains the initial configuration information. Further, the shared storage is mounted to the local working path, so that the processes in the container group can access the shared storage in the form of directly accessing local files.

[0060] In addition, the initial configuration management resource object in the container management cluster is mounted to a designated directory in the container group, so that the container group obtains the configuration information in the initial configuration management resource object as the current configuration information.

[0061] Optionally, the shared storage is at least one of a network file system, a reliable autonomous distributed object storage system, and a distributed file system.

[0062] S230, in response to a configuration file change message initiated by a file change monitoring system, obtaining an updated configuration file in the shared storage under the local working path mounted by the shared storage.

[0063] The file change monitoring system runs in the node where the current container group is located, and is used for monitoring changes of the configuration file in the shared storage. Further, the updated configuration information and the current configuration information in the current configuration file are compared to determine the information difference, and finally the current configuration file is incrementally updated based on the information difference.

[0064] ​The shared storage listens for update events of configuration management resource objects in the container management platform and extracts the updated configuration information from the updated configuration management resource objects. By adopting an incremental update strategy, only the changed configuration parts are updated, rather than a full overwrite of the entire configuration management resource object each time. This significantly reduces network load during updates and improves synchronization efficiency.

[0065] In this embodiment of the invention, the file change monitoring system runs on the node where the current container group resides. It monitors changes to configuration files in shared storage and, upon detecting a change, sends a configuration file change message to the container group on that node. Upon receiving the configuration file change message from the file change monitoring system, the container group retrieves the updated configuration file from the shared storage at its local working path.

[0066] In addition, to ensure system reliability, the shared storage also supports configuration rollback functionality. When configuration management resource object updates fail or encounter problems, the shared storage's version control mechanism can be used to restore to a historical version, ensuring system reliability.

[0067] S240. In the update configuration file, determine the target update configuration file associated with the current container group.

[0068] In this embodiment of the invention, when multiple update configuration files are obtained, it is necessary to determine the target update configuration file associated with the current container group from among the update configuration files.

[0069] S250: Update the current configuration information based on the target update configuration file.

[0070] The technical solution of this invention combines the configuration management resource object of the container management cluster with external shared storage. Leveraging the efficient file access and strong consistency features of shared storage, the content of the configuration management resource object is directly stored in the shared storage. Multiple nodes or container groups can read the configuration file in real time through the shared storage, without relying on the container management cluster's interface for synchronous updates. This eliminates synchronization latency issues and consistency problems between different nodes or container groups. By monitoring file changes in the shared storage, when the configuration management resource is updated, all container groups using that resource can detect the update in real time and read the latest configuration content from the shared storage, reducing update latency and improving resource utilization efficiency.

[0071] Example 3

[0072] Figure 3 This is a schematic diagram of a configuration update system provided in Embodiment 3 of the present invention. Figure 3As shown, the system comprises a shared storage 1 and a container management cluster 2, the container management cluster 2 comprising at least one node 21, at least one container group 211 and a file change monitoring system 212 running in each node 21;

[0073] The shared storage 1 is configured to, in response to listening to a configuration management resource object update event of the container management cluster 2, update a current configuration file currently stored based on an updated configuration management resource object.

[0074] In the embodiment of the application, the shared storage 1 updates the current configuration file currently stored based on the updated configuration management resource object in response to listening to the configuration management resource object update event of the container management cluster 2, so that the container group 211 mounted on the shared storage 1 can obtain the updated configuration file in the shared storage 1 in time.

[0075] Through the high availability and consistency guarantee mechanism of the shared storage 1, it is ensured that the data read by all nodes and container groups 211 is always consistent when the configuration file is updated. When multiple container groups 211 or nodes 21 access the same configuration, the problem of inconsistent data caused by concurrent access is avoided.

[0076] The shared storage 1 is at least one of a network file system, a reliable autonomous distributed object storage system, and a distributed file system.

[0077] The file change monitoring system 212 is configured to monitor the configuration file in the shared storage 1 and send a configuration file change message to the container group 211 in the node 21 when the configuration file in the shared storage 1 changes.

[0078] In the embodiment of the application, the file change monitoring system 212 runs in the node 21 where the current container group 211 is located, and is configured to monitor the configuration file in the shared storage 1. When the configuration file in the shared storage 1 changes, the file change monitoring system 212 sends a configuration file change message to the container group 211 in the node 21, so that the container group 211 can obtain the updated configuration information in time.

[0079] The container group 211 is configured to perform the following operations:

[0080] Create a mounting configuration of the shared storage 1; the shared storage 1 stores a configuration file containing configuration information in the configuration management resource object;

[0081] In response to the configuration file change message initiated by the file change monitoring system 212, obtain an updated configuration file from the shared storage 1 based on the mounting configuration;

[0082] The file change monitoring system 212 is run in the node 21 where the current container group 211 is located, and is used for monitoring changes of the configuration file in the shared storage 1.

[0083] The current configuration information is updated based on the updated configuration file.

[0084] When the container group 211 is mounted on the shared storage 1, the container group 211 acts as a client, and the shared storage 1 adopts a distributed system design, and the consistency of the data written by the container group 211 is ensured according to the design and configuration of the distributed storage.

[0085] The shared storage 1 is specifically used for:

[0086] In response to monitoring a configuration management resource object update event in the container management platform, updated configuration information in the updated configuration management resource object is extracted;

[0087] The updated configuration information is compared with current configuration information in the current configuration file to determine information differences;

[0088] The current configuration file is incrementally updated based on the information differences.

[0089] In the embodiment of the application, the shared storage 1 responds to the monitoring of the configuration management resource object update event in the container management platform, extracts the updated configuration information in the updated configuration management resource object, further compares the updated configuration information with the current configuration information in the current configuration file to determine information differences, and finally incrementally updates the current configuration file based on the information differences. Through the incremental update mechanism, only the changed part of the configuration file is updated, rather than the entire configuration file content being written into the shared storage 1 every time. In this way, the network transmission pressure and storage pressure caused by configuration update can be effectively reduced.

[0090] The shared storage 1 is further used for:

[0091] In response to a configuration management resource object update failure, a version management mechanism is run to roll back the updated configuration file.

[0092] In the embodiment of the application, a version management mechanism of the configuration file is run in the shared storage 1, so that the rollback operation of the configuration can be ensured. For example, in a distributed file system, a file version control function can be enabled. When the configuration update fails, for example, the configuration management resource object update fails, the version management mechanism is run to roll back the configuration file to a previous version to restore the normal operation of the system, thereby enhancing the reliability of the system.

[0093] The configuration information in the configuration management resource object is configured as the configuration source of the shared storage 1, the original configuration information of the program can be recorded, and the shared storage 1 records the configuration information update in the configuration management resource object, so that the version strategy of the background distributed service of the shared storage 1 is used to record the update of the configuration content without restarting the container group 211. The version control and rollback management of the shared storage 1 are key mechanisms to guarantee data consistency, traceability and disaster recovery capability. The background storage system realizes version control through snapshot, versioned object, incremental backup and the like, and supports rollback to a specific historical state, thereby providing a more flexible mechanism for version control of the application program.

[0094] The technical scheme of the embodiment of the application combines the configuration management resource object of the container management cluster and the external shared storage, directly stores the content of the configuration management resource object in the shared storage by using the efficient file access characteristics and the strong consistency features of the shared storage, and multiple nodes or container groups read the configuration file in real time through the shared storage without having to rely on the interface of the container management cluster for synchronous update, thereby solving the problem of synchronization delay and the consistency problem between different nodes or container groups. By monitoring the file change in the shared storage, when the configuration management resource is updated, all container groups using the configuration management resource can perceive the update in real time and read the latest configuration content from the shared storage, thereby reducing the update delay and improving the utilization efficiency of the resource.
