[0060] Embodiment one

[0061] Figure 1 is a flowchart of a data communication method provided by the first embodiment of the present application. The present embodiment can be applied to the case of realizing communication between external devices and cluster containers in the same VPC network. The method can be executed by a data communication device, which can be realized by software and / or hardware, and can be directly integrated in an electronic device that executes the method, which can be a terminal device or a server device. The present embodiment does not limit the type of electronic device that executes the data communication method. Specifically, as shown in Figure 1 the data communication method can specifically include the following steps:

[0062] S110, obtaining a proxy service creation request, and creating a target proxy service according to the proxy service creation request.

[0063] The proxy service creation request can be a request to create a proxy service. Optionally, the proxy service can be a forwarding proxy service in the K8s cluster, for example, an SVC in the K8s cluster, i.e., a Service resource object in the K8s cluster. It can be understood that the container in the K8s cluster is the carrier of the application program, and the application program can be accessed through the IP address of the container. However, the IP address of the container is not fixed, so the IP address of the container cannot be directly used to access the service. Therefore, the K8s cluster provides a Service resource. The Service can aggregate multiple containers that provide the same service and provide a unified entry address, so that the application program in the container can be accessed by accessing the entry address of the Service. The target proxy service can be a proxy service created according to the proxy service creation request.

[0064] In the embodiment of the present application, the proxy service creation request is acquired to create a target proxy service according to the proxy service creation request. It should be noted that the embodiment of the present application does not limit the specific implementation manner of creating the target proxy service according to the proxy service creation request, as long as the creation of the target proxy service can be realized. For example, after the proxy service creation request is acquired, the K8s cluster underlying kube-apiserver interface can be called to create the target proxy service according to the proxy service creation request through the kube-api server interface.

[0065] In S120, the proxy service type of the target proxy service is determined, and the substitute proxy service of the target proxy service is determined according to the proxy service type.

[0066] The proxy service type can be the type of the proxy service, for example, the proxy service type with its own IP address, or the proxy service type without its own IP address, and the like, and the embodiment of the present application does not limit this. The substitute proxy service can be a proxy service that can replace the target proxy service.

[0067] It should be noted that the embodiment of the present application does not limit the specific implementation manner of determining the proxy service type of the target proxy service, as long as the proxy service type of the target proxy service can be realized. For example, the proxy service type of the target proxy service can be determined according to the clusterIP parameter in the proxy service creation request.

[0068] In the embodiment of the present application, after the target proxy service is created according to the proxy service creation request, the proxy service type of the target proxy service can be further determined to determine the substitute proxy service of the target proxy service according to the proxy service type. It can be understood that in the same VPC network, the containers in the K8s cluster and the external devices outside the cluster cannot communicate through the SVC in the K8s cluster, so the substitute proxy service of the target proxy service can be determined to realize the communication between the containers in the cluster and the external devices outside the cluster in the same VPC network through the substitute proxy service.

[0069] In S130, the data communication request is responded through the substitute proxy service in the case that the data communication request is received, wherein the data communication request is a data request between the external devices and the cluster containers in the same network.

[0070] The data communication request can be a data request for communication, for example, an access request, and the like, and the embodiments of the present application do not limit the same. The same network can be the same VPC network. The cluster external device can be a virtual machine device outside the K8s cluster, or a physical machine device outside the K8s cluster, and the embodiments of the present application do not limit the same. The cluster container can be a container in the K8s cluster.

[0071] In the embodiments of the present application, after the alternative proxy service of the target proxy service is determined according to the proxy service type, the data communication request can be further responded through the alternative proxy service when the data communication request is received, so as to realize the data communication between the cluster external device and the cluster container in the same network.

[0072] The technical scheme of the present embodiment, by obtaining a proxy service creation request, creating a target proxy service according to the proxy service creation request, determining the proxy service type of the target proxy service, and determining the alternative proxy service of the target proxy service according to the proxy service type, so as to respond to the data communication request through the alternative proxy service when the data communication request is received, solves the problem of high cost and difficult maintenance caused by modifying the source code in the prior art, and can realize the communication between the cluster external device and the cluster container in the same VPC network, thereby reducing the labor cost and improving the maintainability of the system.

[0073] Embodiment Two

[0074] Figure 2 is a flowchart of a data communication method provided by the second embodiment of the present application, and the present embodiment is a further refinement of the above-mentioned technical solutions, and gives a plurality of specific optional implementation manners for determining the alternative proxy service of the target proxy service according to the proxy service type, and responding to the data communication request through the alternative proxy service. The technical scheme in the present embodiment can be combined with each optional scheme in one or more of the above-mentioned embodiments. As shown in the above-mentioned flowchart, the method can include the following steps: Figure 2

[0075] S210, obtaining a proxy service creation request, and creating a target proxy service according to the proxy service creation request.

[0076] S220, determining the proxy service type of the target proxy service.

[0077] S230, in the case where the proxy service type is determined to be a normal proxy service type, determining a current network identifier.

[0078] ​The common proxy service type can be a type of common proxy service. The common proxy service can be a proxy service with an IP address. It can be understood that the common proxy service is also a header proxy service, which has an IP address of its own, and the common proxy service can be accessed through the IP address. That is, the IP address of the target proxy service of the common proxy service type can be obtained by resolving the target proxy service of the common proxy service type. The current network identifier can be an identifier of a VPC network in which the current K8s cluster is located. It can be understood that the current network identifier can uniquely identify the current network.

[0079] In the embodiments of the present application, after determining the proxy service type of the target proxy service, the current network identifier can be further determined when the proxy service type is a common proxy service type.

[0080] S240, creating a load balancing service according to the target proxy service and the current network identifier.

[0081] The load balancing service can be a service that can balance and distribute received data communication requests to a load. It can be understood that the load can be a container in the K8s cluster.

[0082] In the embodiments of the present application, after determining the current network identifier, the load balancing service can be further created according to the target proxy service and the current network identifier. It can be understood that the IP address of the current network can be determined according to the current network identifier, so as to create the load balancing service according to the target proxy service and the IP address of the current network, so that the load balancing service can be in the same network segment as the current network. Optionally, creating the load balancing service according to the target proxy service and the current network identifier can include calling a vpc-api interface to create the load balancing service according to the target proxy service and the current network identifier through the vpc-api interface.

[0083] S250, updating a first data structure of the target proxy service according to the load balancing service, and determining the substitute proxy service according to a first data structure update result.

[0084] The first data structure can be a data structure of the target proxy service of the common proxy service type. It can be understood that the data structure of the target proxy service can be determined after the target proxy service is created according to the proxy service creation request. The first data structure update result can be a new data structure obtained after the first data structure is updated.

[0085] In the embodiment of the present application, after the load balancing service is created according to the target proxy service and the current network identifier, the first data structure of the target proxy service can be further updated according to the load balancing service to determine the substitute proxy service according to the update result of the first data structure.

[0086] The above technical solution proposes a specific application scenario of the proxy service type being the ordinary proxy service type, so as to determine the substitute proxy service of the target proxy service of the ordinary proxy service type, thereby improving the reliability of communication between the cluster external device and the cluster container in the same VPC network.

[0087] Optionally, updating the first data structure of the target proxy service according to the load balancing service can include: determining the IP address corresponding to the load balancing service; and updating the IP address corresponding to the first data structure to the IP address corresponding to the load balancing service.

[0088] Specifically, after the load balancing service is created according to the target proxy service and the current network identifier, the IP address corresponding to the load balancing service can be further determined to update the IP address corresponding to the first data structure to the IP address corresponding to the load balancing service.

[0089] The above technical solution proposes a specific implementation manner of updating the first data structure of the target proxy service according to the load balancing service, which can more accurately update the first data structure of the target proxy service.

[0090] Optionally, after the first data structure of the target proxy service is updated according to the load balancing service, the update result of the first data structure can be stored in a database for display to a user.

[0091] S260, in a case where the proxy service type is determined to be the headless proxy service type, a second data structure of the target proxy service is determined, and the substitute proxy service is determined according to the second data structure.

[0092] The headless proxy service type can be the type of headless proxy service. The headless proxy service can be a proxy service without an assigned IP address. It can be understood that the IP addresses of all containers managed by the target proxy service of the headless proxy service type can be obtained by parsing the target proxy service of the headless proxy service type. The second data structure can be the data structure of the target proxy service of the headless proxy service type.

[0093] In the embodiments of the present application, after determining the proxy service type of the target proxy service, the second data structure of the target proxy service can be further determined when the proxy service type is a headless proxy service type, so as to determine the substitute proxy service according to the second data structure. Optionally, after determining the second data structure of the target proxy service, the second data structure can be stored in the database for display to the user.

[0094] The above technical solution proposes a specific application scenario of the proxy service type being a headless proxy service type, so as to determine the substitute proxy service of the target proxy service of the headless proxy service type, thereby improving the reliability of communication between the cluster external device and the cluster container under the same VPC network.

[0095] Optionally, after determining the substitute proxy service of the target proxy service according to the proxy service type, the K8s cluster underlying kube-api server interface can be further called to delete the target proxy service through the kube-apiserver interface.

[0096] S270, in the case of receiving a data communication request, responding to the data communication request through the substitute proxy service.

[0097] Optionally, responding to the data communication request through the substitute proxy service can include: in the case of determining that the data communication request includes the service IP address of the substitute proxy service, responding to the data communication request through the substitute proxy service according to the service IP address.

[0098] The service IP address can be the IP address of the substitute proxy service. It can be understood that if the data communication request includes the service IP address of the substitute proxy service, it means that the proxy service type of the target proxy service corresponding to the substitute proxy service is a normal proxy service type.

[0099] Specifically, after receiving the data communication request, the service IP address of the proxy service can be further included in the data communication request, and the data communication request can be responded to by the proxy service according to the service IP address. It can be understood that there can be multiple proxy services before receiving the data communication request, and each proxy service can manage containers in multiple K8s clusters. After receiving the data communication request, if the service IP address is included in the data communication request, the service IP address in the data communication request can be compared with the IP address corresponding to each proxy service for consistency to determine the proxy service whose IP address is consistent with the service IP address, so that the data communication request is forwarded to the container managed by the proxy service. That is, if the service IP address in the data communication request is the IP address of the proxy service, it means that the service IP address is consistent with the IP address of the proxy service, and the data communication request can be responded to by the proxy service.

[0100] The above technical solution proposes an application scenario in which the data communication request includes the service IP address of the proxy service, so that the data communication request can be responded to by the proxy service according to the service IP address in the data communication request, thereby enabling the communication between the external device and the container in the cluster in the same VPC network to be realized by the proxy service when the data communication request includes the service IP address of the proxy service.

[0101] Optionally, after creating the target proxy service according to the proxy service creation request, the target proxy service corresponding service internal network resolution record can be created according to the target proxy service, and the target proxy service corresponding service attribute information can be determined according to the service internal network resolution record. Correspondingly, responding to the data communication request by the proxy service can include: in the case where the data communication request includes the target proxy service corresponding service attribute information, responding to the data communication request by the proxy service according to the service attribute information; wherein the service internal network resolution record can include a first type internal network resolution record and / or a second type internal network resolution record; the service attribute information includes service domain name information and / or service port information.

[0102] The service internal network resolution record can be an internal network resolution record corresponding to the target proxy service. The first type of internal network resolution record can be a type of internal network resolution record, for example, can be an internal network resolution record of type A, and the like. The present embodiment does not limit the second type of internal network resolution record. The second type of internal network resolution record can be another type of internal network resolution record, for example, can be an internal network resolution record of type SRV, and the like. The present embodiment does not limit the service attribute information. The service attribute information can be attribute information corresponding to the target proxy service, for example, can be domain name information of the target proxy service, or can be port information of the target proxy service, and the like. The present embodiment does not limit the service domain name information. The service domain name information can be domain name information of the target proxy service. The service port information can be port information of the target proxy service.

[0103] Specifically, after creating the target proxy service according to the proxy service creation request, the service internal network resolution record corresponding to the target proxy service can be further created according to the target proxy service, and the service attribute information corresponding to the target proxy service is determined according to the service internal network resolution record, so that when the service attribute information corresponding to the target proxy service is included in the data communication request, the surrogate proxy service responds to the data communication request according to the service attribute information. Optionally, creating the service internal network resolution record corresponding to the target proxy service according to the target proxy service can include calling a vpc-api interface to create the service internal network resolution record corresponding to the target proxy service according to the target proxy service through the vpc-api interface.

[0104] It can be understood that there can be multiple surrogate proxy services before receiving the data communication request. After receiving the data communication request, if the service attribute information is included in the data communication request, the service attribute information in the data communication request can be compared with the attribute information of each surrogate proxy service for consistency, to determine the surrogate proxy service whose attribute information is consistent with the service attribute information, so that the data communication request is forwarded to the container managed by the surrogate proxy service through the surrogate proxy service. That is, if the service attribute information in the data communication request is the attribute information of the target proxy service, it means that the service attribute information is consistent with the attribute information of the surrogate proxy service corresponding to the target proxy service, and the data communication request can be responded through the surrogate proxy service.

[0105] Optionally, when the proxy service type of the target proxy service is a normal proxy service type, the service internal network resolution record corresponding to the target proxy service can be a first type of internal network resolution record. When the proxy service type of the target proxy service is a headless proxy service type, the service internal network resolution record corresponding to the target proxy service can be a first type of internal network resolution record, a second type of internal network resolution record, or a first type of internal network resolution record and a second type of internal network resolution record. The present embodiment does not limit the service attribute information.

[0106] The technical solution described above creates a service-intranet resolution record corresponding to the target proxy service, and determines service attribute information according to the service-intranet resolution record, so that when the service attribute information is included in the data communication request, the data communication request is responded to by the substitute proxy service according to the service attribute information, thereby enabling the communication between the cluster external device and the cluster container in the same VPC network to be realized by the substitute proxy service when the service attribute information is included in the data communication request.

[0107] Optionally, after determining the substitute proxy service of the target proxy service according to the proxy service type, the method can further include: in the case of listening to a container new event, determining a first substitute proxy service corresponding to the new container, and adding the new container to a member list of the first substitute proxy service; in the case of listening to a container destruction event, determining a second substitute proxy service corresponding to the destroyed container, and removing the destroyed container from the member list of the second substitute proxy service.

[0108] The container new event can be an event of a new container. The new container can be a newly created container. The first substitute proxy service can be a substitute proxy service for managing the new container. The member list of the first substitute proxy service can be a list of all containers managed by the substitute proxy service for managing the new container. The container destruction event can be an event of a destroyed container. The destroyed container can be a destroyed container. The second substitute proxy service can be a substitute proxy service for managing the destroyed container. The member list of the second substitute proxy service can be a list of all containers managed by the substitute proxy service for managing the destroyed container.

[0109] Specifically, after determining the substitute proxy service of the target proxy service according to the proxy service type, the container new event and the container destruction event can be further listened to. When the container new event is listened to, the first substitute proxy service corresponding to the new container is determined to add the new container to the member list of the first substitute proxy service. When the container destruction event is listened to, the second substitute proxy service corresponding to the destroyed container is determined to remove the destroyed container from the member list of the second substitute proxy service. Optionally, the container new event and the container destruction event can be listened to by the watch mode of the K8s client (client). Another optional way is to determine the first substitute proxy service corresponding to the new container by the label (label) method, and to determine the second substitute proxy service corresponding to the destroyed container by the label method.

[0110] The technical solution increases the supplementary processing strategy of the monitoring event, that is, when the container creation event is monitored, the newly created container is added to the member list of the corresponding surrogate service, and when the container destruction event is monitored, the destroyed container is deleted from the member list of the corresponding surrogate service, so that the container managed by the surrogate service can be added or deleted in time, and the reliability of communication is further improved.

[0111] Optionally, after adding the newly created container to the member list of the first surrogate service, the container internal network resolution record of the newly created container can be obtained, and the container domain name information of the newly created container can be determined according to the container internal network resolution record; in the case that the container domain name information of the newly created container is included in the data communication request, the data communication request is responded according to the container domain name information.

[0112] Optionally, after adding the newly created container to the member list of the first surrogate service, the container internal network resolution record of the newly created container can be obtained, and the container domain name information of the newly created container can be determined according to the container internal network resolution record; in the case that the container domain name information of the newly created container is included in the data communication request, the data communication request is responded according to the container domain name information.

[0113] Optionally, after adding the newly created container to the member list of the first surrogate service, the container internal network resolution record of the newly created container can be obtained, and the container domain name information of the newly created container can be determined according to the container internal network resolution record; in the case that the container domain name information of the newly created container is included in the data communication request, the data communication request is responded according to the container domain name information.

[0114] It can be understood that each surrogate service can manage multiple containers, and each container can have its corresponding internal network resolution record. If the container domain name information is included in the data communication request, the container domain name information in the data communication request can be compared with the internal network resolution record of each container for consistency, to determine the container consistent with the container domain name information, so as to respond to the data communication request through the container. That is, if the container domain name information in the data communication request is the domain name information of the newly created container, the newly created container can be determined through the container domain name information, so as to respond to the data communication request through the newly created container.

[0115] The technical solution obtains the container internal network resolution record of the newly created container, and determines the container domain name information of the newly created container according to the container internal network resolution record, so as to respond to the data communication request according to the container domain name information when the container domain name information is included in the data communication request, thereby enabling the communication between the cluster external device and the cluster container under the same VPC network when the container domain name information is included in the data communication request.

[0116] Optionally, after removing the destroyed container from the member list of the second surrogate service, the internal network resolution record corresponding to the destroyed container can be further deleted.

[0117] Optionally, after removing the destroyed container from the member list of the second surrogate service, the internal network resolution record corresponding to the destroyed container can be further deleted.Figure 3 is a container new creation and destruction event execution logic schematic diagram provided by the second embodiment of the present application, as shown in Figure 3 As shown, the new creation and destruction events of the pod (container) are listened to through the watch mode of the k8s client, and the newly created pod is found through the label mode to correspond to the load balancing service, added to the member of the corresponding listener, and then written into the internal network resolution record of type A. The destroyed pod is found through the label mode to correspond to the load balancing service, deleted from the member in the corresponding listener, and the corresponding internal network resolution record is deleted.

[0118] The technical scheme of the embodiment, by obtaining a proxy service creation request, creating a target proxy service according to the proxy service creation request, and determining the proxy service type of the target proxy service, determines the current network identifier when the proxy service type is a normal proxy service type, and creates a load balancing service according to the target proxy service and the current network identifier, updates the first data structure of the target proxy service according to the load balancing service, and determines the replacement proxy service according to the first data structure update result; or when the proxy service type is a headless proxy service type, determine the second data structure of the target proxy service, and determine the replacement proxy service according to the second data structure, so as to respond to the data communication request through the replacement proxy service when receiving the data communication request, solve the problem of high cost and difficult maintenance caused by modifying the source code in the prior art, and realize the communication between the cluster external equipment and the cluster container in the same VPC network, thereby reducing the artificial cost and improving the maintainability of the system.

[0119] Embodiment three

[0120] In order for those skilled in the art to better understand the data communication method of the embodiment, a specific example is used to illustrate, Figure 4 is a timing diagram of a normal proxy service creation provided by the third embodiment of the present application, Figure 5 is a timing diagram of a headless proxy service creation provided by the fourth embodiment of the present application, as shown in Figure 4 , 5 The method can specifically include:

[0121] (1) Through the Service related operation interface of kube-external proxy kube-apiserver. Since the native SVC resource object of the K8s cluster has many properties, when kube-external receives a Service creation request, the underlying kube-apiserver real interface is called to create a native SVC.

[0122] (2) If the native SVC is a common SVC, a vpc-api interface is directly called to create an LB (load balancing service) and an internal network resolution record of type A, and the IP in the json content returned by creating the native SVC is replaced, finally the native SVC created by the K8s underlying is deleted, and the modified json content is stored in the database.

[0123] (3) If the native SVC is a headless SVC, a vpc-api interface is called to create an internal network resolution record of type A and type SRV, the json content returned by creating the native SVC is stored in the database, and the native SVC created by the K8s underlying is deleted.

[0124] (4) When receiving an access request, the native SVC in the K8s cluster is replaced by the LB or the internal network resolution record to respond to the access request.

[0125] The above technical solution uses the LB and the internal network resolution to replace the K8s native Service by the way of intercepting the kube-apiserver interface through the kube-external as a proxy, so that the network of the container deployment application and the virtual machine and the physical machine deployment application is communicated, thereby achieving the effect that the containers, the virtual machines and the physical machines intercommunicate under the same VPC.
