[0028] According to one aspect of an embodiment of the present application, a method for controlling the capacity of a containerized application is provided. The method for controlling the capacity of a containerized application is widely used in smart home, smart home, smart home device ecosystem, smart home ecosystem and other whole-house intelligent digital control application scenarios.

[0030] In another embodiment, the capacity control method of containerized applications provided in this application can be applied to smart home appliances. Among them, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology, and network communication technology into home appliances, which have the function of automatically sensing the state of residential space, the state of the home appliances themselves, and the state of home appliance services, and can automatically control and receive control instructions from residential users in the home or remotely. It can be understood that smart home appliances are a component of smart homes.
[0031] Figure 2 It is a flow chart of the capacity control method of containerized applications provided in this application.
[0032] In order to further introduce the capacity control method of containerized applications provided by this application, Figure 2 Provide explanation.
[0033] In an exemplary embodiment of the present application, the containerized application can be deployed on a container service management platform based on the Kubernetes mechanism. It is understandable that the application subject of the present application can be a container service management platform based on the Kubernetes mechanism, wherein the container service management platform is deployed with the containerized application. Figure 2 It can be seen that the capacity control method for containerized applications may include steps 210 to 230, and each step will be introduced below.
[0034] In step 210, a protocol message of an access request of a containerized application is received within a current time period.
[0035] In one embodiment, a protocol message of an access request of a containerized application may be received within a current time period.
[0036] It should be noted that in the present application, access requests are received in units of a time period, and subsequent processing is performed based on the access requests in order to achieve the query rate per second (also known as QPS), that is, to expand or shrink the containerized application according to the access situation of the containerized application, thereby effectively avoiding the impact of unbalanced traffic generated in the case of a surge or sudden decrease in access on the operation of the containerized application.
[0037] In another example, the container service management platform is a container service management platform based on the Kubernetes mechanism. Multiple containerized applications are deployed on the container service management platform.
[0038] In step 220, the proxy container based on the container service management platform parses the protocol message to obtain a parsing result.
[0039] In step 230, the containerized application is expanded or reduced in capacity based on the number of valid access requests and / or the number of valid TCP connections.
[0040] In one embodiment, the protocol message can be intercepted, forwarded, and parsed by a proxy container at the protocol layer of the container service management platform, and the parsing result can be obtained, thereby laying a foundation for expanding or shrinking the containerized application based on the parsing result.
[0041] The parsing result may include the number of valid access requests and / or the number of valid transmission control protocol connections, where a valid access request is an access request that is allowed to be accessed, and a valid transmission control protocol is a transmission control protocol that is allowed to be forwarded by a proxy container.
[0042] It should be noted that a valid access request refers to an access request that is allowed to access. In the application process, the protocol message of the access request includes a transmission control protocol. If the transmission control protocol is not an allowed transmission control protocol, then the access request can be considered not to be a valid access request. Among them, the allowed transmission control protocol can be determined according to actual conditions, for example, it can be an E++ protocol. In this embodiment, the allowed transmission control protocol is not specifically limited.
[0043] In another embodiment, the capacity of the containerized application may be expanded or reduced based on the number of valid access requests and / or the number of valid transmission control protocol connections, thereby enabling the containerized application to be expanded or reduced according to the access situation to the containerized application, thereby effectively avoiding the impact of unbalanced traffic generated when access surges or decreases on the operation of the containerized application.
[0044] Figure 3This is a flowchart of expanding or shrinking a containerized application based on the number of valid access requests and / or the number of valid transmission control protocol connections provided by the present application.
[0045] The following will be combined Figure 3 The process of scaling a containerized application up or down based on the number of valid access requests and / or the number of valid transmission control protocol connections is described.
[0046] In an exemplary embodiment of the present application, Figure 3 It can be seen that based on the number of valid access requests and / or the number of valid transmission control protocol connections, the expansion or reduction processing of the containerized application may include step 310 and step 320, and each step will be introduced below.
[0047] In step 310, access index information is determined based on the number of valid access requests and / or the number of valid TCP connections.
[0048] In step 320, the containerized application is expanded or reduced in capacity based on the access indicator information.
[0049] In one embodiment, Prometheus in the container service management platform can periodically collect access indicator information transmitted by the proxy container. And register the access indicator information to the server application program interface (also known as API server) of the container service management platform. Among them, the access indicator information is used to characterize the comparison between the number of valid access requests in the current time period and the number of valid access requests in the previous time period, and\or the comparison between the number of valid transmission control protocol connections in the current time period and the number of valid transmission control protocol connections in the previous time period.
[0050] Furthermore, the capacity of containerized applications can be expanded or reduced based on the access indicator information, thereby effectively avoiding the impact of unbalanced traffic caused by a surge or decrease in access on the operation of containerized applications.
[0051] In another exemplary embodiment of the present application, the above-described embodiment is continued to be used as an example for explanation. Before the containerized application is expanded or reduced in capacity based on the access index information (corresponding to step 320), the capacity control method of the containerized application may further include:
[0052] Register access indicator information to the server application programming interface of the container service management platform;
[0053] Reading access indicator information from the server application program interface. In one embodiment, the access indicator information can be read from the server application program interface, wherein the HPA expands or shrinks the containerized application according to the access indicator information provided by the APISERVER.
[0054] Among them, HPA is a resource object of Kubernetes, which can dynamically scale the number of Pods in sets such as statefulSet, replica Set, and deployment according to certain indicators, so that the services running on it have a certain degree of adaptability to changes in indicators.
[0055] Through the aforementioned embodiments, the HPA solutions of QPS of different back-end technology stacks can be unified through protocol proxy; and the platform capabilities and businesses can be decoupled through non-invasive integration, so that business development can focus on the business itself. The general capabilities are well unified on the platform, which achieves standardized processing and greatly reduces the subsequent maintenance costs.
[0056] In another exemplary embodiment of the present application, the above-mentioned embodiment is continued to be used as an example for description, wherein, based on the access indicator information, the containerized application is expanded or reduced in capacity (corresponding to step 320), which can be implemented in the following manner:
[0057] When the access indicator information is the first access indicator information, the containerized application is expanded, wherein the first access indicator information is that the number of valid access requests in the current time period is greater than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is greater than the number of valid transmission control protocol connections in the previous time period;
[0058] When the access indicator information is the second access indicator information, the containerized application is scaled down, wherein the second access indicator information is that the number of valid access requests in the current time period is less than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is less than the number of valid transmission control protocol connections in the previous time period.
[0059] In one embodiment, when the number of valid access requests in the current time period is greater than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is greater than the number of valid transmission control protocol connections in the previous time period, it means that the access volume in the current time period is greater than the access volume in the previous time period. In order to meet the processing capacity requirements, the containerized application needs to be expanded.
[0060] In another exemplary embodiment of the present application, the expansion of the containerized application may be implemented in the following manner:
[0061] Increase the number of minimum work units (also known as PODs) of the container service management platform to achieve capacity expansion for containerized applications.
[0062] It should be noted that Pod is the smallest working unit of Kubernetes (the unit that provides applications). Each Pod contains one or more containers. The containers in the Pod will be scheduled as a whole by the Master to run on a Node. In this embodiment, the number of PODs of the container service management platform can be increased to achieve capacity expansion of containerized applications.
[0063] In one embodiment, when the number of valid access requests in the current time period is less than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is less than the number of valid transmission control protocol connections in the previous time period, it means that the access volume in the current time period is less than the access volume in the previous time period. Under the premise of ensuring processing capacity, in order not to waste resources, the containerized application can be scaled down.
[0064] In another exemplary embodiment of the present application, scaling down the containerized application may be implemented in the following manner:
[0065] Reduce the number of minimum work units (also known as PODs) of the container service management platform to achieve downscaling of containerized applications.
[0066] Figure 4 This is a flow chart of parsing protocol messages based on a proxy container in a container service management platform provided by the present application.
[0067] The following will be combined Figure 4 The process of parsing protocol messages based on the proxy container in the container service management platform is described.
[0068] In an exemplary embodiment of the present application, the protocol message may include a transmission control protocol and access device information. Figure 4 It can be seen that parsing the protocol message based on the proxy container in the container service management platform may include steps 410 to 440, and each step will be introduced below.
[0069] In step 410, based on the proxy container, it is determined whether the TCP is a valid TCP.
[0070] In step 420, when the transmission control protocol is a valid transmission control protocol, it is determined whether the access device is a registered access device based on the access device information.
[0071] In step 430, when the access device is a registered access device, the access request corresponding to the protocol message is regarded as a valid access request.
[0072] In step 440, the number of valid access requests and the number of valid transmission control protocol connections in the current time period are counted, and the number of valid access requests and the number of valid transmission control protocol connections in the current time period are used as the analysis result.
[0073] In one embodiment, the transmission control protocol can be identified based on the proxy container to determine whether the transmission control protocol is a valid transmission control protocol. In one example, a table can be pre-set, and the table includes various valid transmission control protocols. By traversing the table, it can be determined whether the transmission control protocol is a valid transmission control protocol.
[0074] Furthermore, when the transmission control protocol is a valid transmission control protocol, it can be further determined based on the access device information whether the access device is a registered access device. Among them, a registered access device refers to a preset registered device that can access the containerized application. During the application process, by identifying the access device, if the access device is a registered access device, the access request corresponding to the protocol message will be regarded as a valid access request. In other words, the access request in this scenario will truly affect the access volume of the containerized application.
[0075] In another embodiment, the number of valid access requests and the number of valid transmission control protocol connections in the current time period are counted, and the number of valid access requests and the number of valid transmission control protocol connections in the current time period are used as the parsing result, thereby laying a foundation for scaling containerized applications based on the number of valid access requests and / or the number of valid transmission control protocol connections.
[0076] In another exemplary embodiment of the present application, the above-described embodiment is continued to be used as an example for explanation. After determining whether the access device is a registered access device based on the access device information (corresponding to step 420), the method for scaling the containerized application further includes:
[0077] When the access device is not a registered access device, stop responding to the access request corresponding to the protocol message.
[0078] In one embodiment, when it is determined that the access device is not a registered access device, the access request corresponding to the protocol message can be stopped from being responded to, thereby reducing the access traffic. In another example, the data reported by the access device, i.e., the unregistered device, can be filtered to reduce the access traffic.
[0079] Figure 5 This is a schematic diagram of the architecture of the container service management platform based on the Kubernetes mechanism provided in this application.
[0080] In order to further introduce the capacity control method of containerized applications provided by this application, Figure 5 The architecture diagram of the container service management platform based on the Kubernetes mechanism is shown for explanation.
[0081] In one embodiment, in combination Figure 5 It can be seen that business access can send protocol packets corresponding to access requests to SLB (Server Load Balancing), which is the load balancing service at the network entrance. Furthermore, SLB can also forward protocol packets corresponding to access requests to the service of the container service management platform based on the Kubernetes mechanism. Among them, service can be understood as a load balancer for containerized applications.
[0082] Understandably, Figure 5 The framed K8S part can represent a container service management platform based on the kubernetes mechanism.
[0083] In another embodiment, the Service may forward the protocol message corresponding to the access request to the proxy container. The proxy container identifies the protocol, and when it is determined that the protocol is a valid transmission control protocol, it may also determine whether the access device is a registered access device based on the access device information included in the protocol message. If the access device is a registered access device, the access request corresponding to the protocol message is regarded as a valid access request. If it is determined that the access device is not a registered access device, the data reported by the access device, i.e., an unregistered device, may be filtered, thereby reducing access traffic.
[0084] In another embodiment, the proxy container may forward the protocol message to the service container, record the number of valid access requests and the number of valid transmission control protocol connections in the current time period, and provide a standard query externally.
[0085] Furthermore, Prometheus can obtain pod registration information based on the service, regularly collect access indicators (including the number of valid access requests and valid transmission control protocol connections in the current time period) transmitted by the proxy container, and register the access indicators in the API server. HPA can periodically scale containerized applications and adjust the number of pods based on the access indicators provided by the API server.
[0086] In one embodiment, when the number of valid access requests in the current time period is greater than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is greater than the number of valid transmission control protocol connections in the previous time period, it means that the access volume in the current time period is greater than the access volume in the previous time period. In order to meet the processing capacity requirements, the containerized application needs to be expanded.
[0087] In another example, the number of PODs of the container service management platform may be increased to achieve capacity expansion for containerized applications.
[0088] In another embodiment, when the number of valid access requests in the current time period is less than the number of valid access requests in the previous time period, and\or the number of valid transmission control protocol connections in the current time period is less than the number of valid transmission control protocol connections in the previous time period, it means that the access volume in the current time period is less than the access volume in the previous time period. Under the premise of ensuring processing capacity, in order not to waste resources, the containerized application can be scaled down.
[0089] In one embodiment, the number of PODs of the container service management platform may be reduced to achieve scaling down of containerized applications.
[0090] According to the foregoing description, the capacity control method for containerized applications provided in the present application is applied to a container service management platform based on the Kubernetes mechanism. The container service management platform is deployed with a containerized application. In the current time period, the protocol message of the access request of the containerized application; based on the proxy container of the container service management platform, the protocol message is parsed to obtain the number of valid access requests and\or the number of valid transmission control protocol connections; then based on the number of valid access requests and\or the number of valid transmission control protocol connections, the containerized application is expanded or reduced in capacity, so that the containerized application can be expanded or reduced in capacity according to the access situation of the containerized application, effectively avoiding the impact of the unbalanced traffic generated in the case of a surge or sudden decrease in access on the operation of the containerized application.
[0091] Figure 6It is a structural schematic diagram of a capacity control device for containerized applications provided in this application.
[0092] The capacity control device for a containerized application provided in the present application is described below. The capacity control device for a containerized application described below and the capacity control method for a containerized application described above can refer to each other.
[0093] In an exemplary embodiment of the present invention, Figure 6 It can be seen that the capacity control device for containerized applications can be applied to a container service management platform based on the Kubernetes mechanism, and the container service management platform is deployed with the containerized application. The capacity control device for containerized applications can include an acquisition module 610, a parsing module 620, and a processing module 630, and each module will be introduced below.
[0094] The receiving module 610 may be configured to receive a protocol message of an access request of a containerized application within a current time period;
[0095] The parsing module 620 may be configured to parse the protocol message based on the proxy container of the container service management platform to obtain a parsing result, wherein the parsing result includes the number of valid access requests and / or the number of valid transmission control protocol connections, the valid access request is an access request that is allowed to be accessed, and the valid transmission control protocol is a transmission control protocol that is allowed to be forwarded by the proxy container;
[0096] The processing module 630 may be configured to scale up or scale down the containerized application based on the number of valid access requests and / or the number of valid transmission control protocol connections.
[0097] In an exemplary embodiment of the present application, the processing module 630 may implement the following method to expand or reduce the capacity of the containerized application based on the number of valid access requests and / or the number of valid transmission control protocol connections:
[0098] Based on the number of valid access requests and / or the number of valid transmission control protocol connections, access indicator information is determined, wherein the access indicator information is used to characterize the comparison between the number of valid access requests in the current time period and the number of valid access requests in the previous time period, and / or the comparison between the number of valid transmission control protocol connections in the current time period and the number of valid transmission control protocol connections in the previous time period;
