[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, 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 part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0038] Since the IP of the application instance (Pod) is temporary in the K8s public shared cluster environment, the original IP will be recycled as the Pod is killed or rebuilt. At the same time, the same IP may belong to Pods deployed by different business lines at different time points. In addition, when the problem IP is discovered and the time when the Pod to which it belongs needs to be located, the ownership of the IP may have changed, which brings a lot of difficulty to the problem of assigning responsibility for repair. To this end, the embodiments of the present application provide an information query system and method.

[0039] The present application embodiment provides an information query system, such as Figure 1 As shown, it includes: a recording device 11 and a query device 12, wherein the recording device 11 and the query device 12 can be set independently of the physical cluster, and can be set on the same electronic device or on different electronic devices; the information query system also includes: a listening device 13 set in the physical cluster, and the listening device 13 can be set independently of the physical cluster, and can be set on the same electronic device or on a different electronic device as the recording device and the query device;

[0040] The recording device 11 is used to store the IP address information and the attribution information corresponding to each application instance in the physical cluster. The IP address information and the attribution information are stored in the recording device 11 when the state of the application instance in the physical cluster changes. That is, each time the state of the application instance in the physical cluster changes, the IP address information and the attribution information of the application instance are stored in the recording device 11 to ensure that all the IP address information and the attribution information of the application instance in history are recorded in the recording device 11;

[0041] In the embodiment of the present application, an application instance (Pod) may refer to a minimum deployment unit in a Kubernetes (an open source container orchestration system, i.e., K8s, whose main function is to automatically deploy, scale, and manage containerized applications) physical cluster that can create and manage a group of related containers. They share storage resources and can communicate with each other through localhost.

[0042] The recording device can persistently store the Pod's IP address information, operating status, and ownership information, so that even after the Pod goes offline, the IP used can be queried.

[0043] The query device 12 is used to respond to a query request for an application instance in the physical cluster and query the IP address information and / or attribution information corresponding to the query request from the recording device.

[0044] In the embodiment of the present application, the query device 12 can view information through multiple dimensions, for example: query through IP, query through a certain time period, query through the owner, etc.

[0045] The IP address information is the Pod IP, which is allocated by the K8s CNI plug-in. The corresponding IP can only be allocated after the Pod is scheduled to the K8s cluster.

[0046] The monitoring device 13 is used to monitor the trigger event triggered when the state of the application instance changes, and in response to the trigger event, extract the ownership information of the application instance from the instance tag corresponding to the application instance, and obtain the IP address information allocated by the physical cluster to the application instance, and store the ownership information and the IP address information corresponding to the application instance in the recording device 11.

[0047] When an embodiment of the present application receives a query request for an application instance in a physical cluster, it can automatically query the recording device for IP address information and / or attribution information that matches the query request, and the IP address information and attribution information are stored when the status of the application instance in the physical cluster changes, thereby realizing real-time query of the IP address information and / or attribution information of the application instance throughout its history. Even if the IP address information or attribution information changes, it can be tracked, which is convenient for determining the responsibility and repairing the problem.

[0048] In an implementation manner of the present application, the monitoring device 13 is further configured to determine that the triggering event is monitored when the event of creating the application instance is monitored.

[0049] In another implementation manner of the present application, the monitoring device 13 is further configured to determine that the triggering event is monitored when an event of updating the application instance is monitored.

[0050] In another implementation manner of the present application, the monitoring device 13 is further configured to determine that the triggering event is monitored when an event of deleting the application instance is monitored.

[0051] In an embodiment of the present application, the monitoring device 13 can monitor the creation / update / deletion events of the Pod on each K8s cluster, and then extract the instance label (Label) information in the Pod and record the obtained IP address information in the recording device.

[0052] In Kubernetes, Pod Labels are key-value pairs used to identify and organize Pods. They can be used to select and manipulate a group of Pods with the same label, such as in a deployment or service selector.

[0053] Through Pod Label, rich information can be injected into the Pod, and the Pod information is finally persisted in the recording device, which can track the IP allocation record.

[0054] In another embodiment of the present application, the monitoring device 13 is further configured to add an instance offline mark to the instance tag corresponding to the application instance when an event of deleting the application instance is monitored.

[0055] In another embodiment of the present application, the information query system further includes: a sending device 14, which can be set independently of the physical cluster, and can be set on the same electronic device or on different electronic devices as the recording device, the query device and the monitoring device;

[0056] The sending device 14 is further used to obtain the attribution information of the application instance to be sent to the physical cluster, and store the attribution information in the instance tag corresponding to the application instance.

[0057] The sending device 14 stores the attribution information, such as project information, personnel information, etc. When the relevant personnel under the relevant project create an application, the final Pod Label will be filled with the corresponding attribution information, such as project: A, personnel: B, etc., and then sent to the K8s cluster.

[0058] In another embodiment of the present application, the recording device 11 is further used to delete the IP address information and the attribution information whose storage time exceeds a preset threshold every preset time period.

[0059] The recording device 11 in the embodiment of the present application can regularly clean up data that is too old to prevent excessive information from being recorded, which affects query efficiency.

[0060] Based on the above-mentioned embodiment, a flowchart of information interaction between devices in an information query system in actual application can be as follows: Figure 2 shown.

[0061] Figure 2 In the process, the delivery device prepares to deliver the Pod and records the Pod ownership information in the Pod Label;

[0062] The delivery device delivers the Pod with the injected Label to the K8s cluster.

[0063] The monitoring device of the K8s cluster monitors Pod events and extracts information such as ownership from the Pod label. At this time, the Pod is also assigned an IP. The relevant information is prepared to be recorded in the recording device. When it is a deletion event, the Pod is marked as not offline.

[0064] Send the extracted Pod information, such as IP, running status, project, etc., to the recording device, which will record it persistently after receiving it;

[0065] The query device searches by IP, ownership information, etc.

[0066] In another embodiment of the present application, an information query method is also provided. Figure 3 As shown, including:

[0067] Step S101, the monitoring device monitors a trigger event triggered when the state of the application instance changes, and in response to the trigger event, extracts the ownership information of the application instance from the instance tag corresponding to the application instance, obtains the IP address information assigned by the physical cluster to the application instance, and stores the ownership information and the IP address information corresponding to the application instance in the recording device;

[0068] In an embodiment of the present application, when an event of creating the application instance is listened to, it is determined that the trigger event is listened to; when an event of updating the application instance is listened to, it is determined that the trigger event is listened to; when an event of deleting the application instance is listened to, it is determined that the trigger event is listened to, and when an event of deleting the application instance is listened to, an instance offline mark is added to the instance tag corresponding to the application instance.

[0069] Step S102, the recording device stores IP address information and attribution information corresponding to each application instance in the physical cluster, wherein the IP address information and the attribution information are stored in the recording device when the state of the application instance in the physical cluster changes;

[0070] In the embodiment of the present application, the recording device can delete the IP address information and the attribution information whose storage time exceeds a preset threshold every preset time period.

[0071] Step S103 : In response to a query request for an application instance in the physical cluster, the query device queries the recording device for IP address information and / or attribution information corresponding to the query request.

[0072] When an embodiment of the present application receives a query request for an application instance in a physical cluster, it can automatically query the recording device for IP address information and / or attribution information that matches the query request, and the IP address information and attribution information are stored when the status of the application instance in the physical cluster changes, thereby realizing real-time query of the IP address information and / or attribution information of the application instance throughout its history. Even if the IP address information or attribution information changes, it can be tracked, which is convenient for determining the responsibility and repairing the problem.

[0073] In another embodiment of the present application, the method further includes:

[0074] The sending device obtains the attribution information of the application instance to be sent to the physical cluster, and stores the attribution information in the instance tag corresponding to the application instance.
